Nutrient deficiency is commonly a limiting factor in reconstructing ecosystems on disturbed areas such as mines, quarries, and construction sites. An open-cut coal mine in southeastern Australia is being used as a model to explore strategies for reconstructing a sustainable forest ecosystem on a spoil substrate. This study aimed to identify the nutrients limiting forest establishment and ways of ameliorating these. A pot trial, using two endemic Myrtaceae tree species, found that nitrogen was the most growth-limiting nutrient followed by phosphorus. To overcome these spoil nutrient deficiencies, a field trial compared the application of forest topsoil to the addition of two rates of inorganic fertilizer, gypsum, or biosolids on the response of a range of native forest plant species directly seeded into the substrate. Only biosolids significantly increased total nitrogen levels in the spoil. However, all treatments significantly decreased spoil pH, thereby increasing nutrient availability. Topsoil produced the highest plant density of native species due to contributions from its seed bank. Biosolids increased growth of Corymbia maculata. The higher rate of fertilizer addition improved seedling establishment of Mimosaceae and the survival of Myrtaceae species. High nutrient treatments increased weed and grass densities, which may have reduced the nutrient benefit for native species. In conclusion, biosolids and the high rate of fertilizer application ameliorated the nitrogen and phosphorus deficiency of spoil to support growth and survival of reintroduced native species. However, potential benefits were attenuated by competition from accompanying weed growth that could be managed by implementing a control program.

Transfer cell morphology is characterized by a polarized ingrowth wall comprising a uniform wall upon which wall ingrowth papillae develop at right angles into the cytoplasm. The hypothesis that positional information directing construction of wall ingrowth papillae is mediated by Ca2+ signals generated by spatiotemporal alterations in cytosolic Ca2+ ([Ca2+]cyt) of cells trans-differentiating to a transfer cell morphology was tested. This hypothesis was examined using Vicia faba cotyledons. On transferring cotyledons to culture, their adaxial epidermal cells synchronously trans-differentiate to epidermal transfer cells. A polarized and persistent Ca2+ signal, generated during epidermal cell trans-differentiation, was found to co-localize with the site of ingrowth wall formation. Dampening Ca2+ signal intensity, by withdrawing extracellular Ca2+ or blocking Ca2+ channel activity, inhibited formation of wall ingrowth papillae. Maintenance of Ca2+ signal polarity and persistence depended upon a rapid turnover (minutes) of cytosolic Ca2+ by co-operative functioning of plasma membrane Ca2+-permeable channels and Ca2+-ATPases. Viewed paradermally, and proximal to the cytosol-plasma membrane interface, the Ca2+ signal was organized into discrete patches that aligned spatially with clusters of Ca2+-permeable channels. Mathematical modelling demonstrated that these patches of cytosolic Ca2+ were consistent with inward-directed plumes of elevated [Ca2+]cyt. Plume formation depended upon an alternating distribution of Ca2+-permeable channels and Ca2+-ATPase clusters. On further inward diffusion, the Ca2+ plumes coalesced into a uniform Ca2+ signal. Blocking or dispersing the Ca2+ plumes inhibited deposition of wall ingrowth papillae, while uniform wall formation remained unaltered. A working model envisages that cytosolic Ca2+ plumes define the loci at which wall ingrowth papillae are deposited.

BACKGROUND: Transfer cells are characterized by intricate ingrowth walls, comprising an uniform wall upon which wall ingrowths are deposited. The ingrowth wall forms a scaffold to support an amplified plasma membrane surface area enriched in membrane transporters that collectively confers transfer cells with an enhanced capacity for membrane transport at bottlenecks for apo-/symplasmic exchange of nutrients. However, the underlying molecular mechanisms regulating polarized construction of the ingrowth wall and membrane transporter profile are poorly understood. RESULTS: An RNAseq study of an inducible epidermal transfer cell system in cultured Vicia faba cotyledons identified transfer cell specific transcriptomes associated with uniform wall and wall ingrowth deposition. All functional groups of genes examined were expressed before and following transition to a transfer cell fate. What changed were the isoform profiles of expressed genes within functional groups. Genes encoding ethylene and Ca(2+) signal generation and transduction pathways were enriched during uniform wall construction. Auxin-and reactive oxygen species-related genes dominated during wall ingrowth formation and ABA genes were evenly expressed across ingrowth wall construction. Expression of genes encoding kinesins, formins and villins was consistent with reorganization of cytoskeletal components. Uniform wall and wall ingrowth specific expression of exocyst complex components and SNAREs suggested specific patterns of exocytosis while dynamin mediated endocytotic activity was consistent with establishing wall ingrowth loci. Key regulatory genes of biosynthetic pathways for sphingolipids and sterols were expressed across ingrowth wall construction. Transfer cell specific expression of cellulose synthases was absent. Rather xyloglucan, xylan and pectin biosynthetic genes were selectively expressed during uniform wall construction. More striking was expression of genes encoding enzymes for re-modelling/degradation of cellulose, xyloglucans, pectins and callose. Extensins dominated the cohort of expressed wall structural proteins and particularly so across wall ingrowth development. Ion transporters were selectively expressed throughout ingrowth wall development along with organic nitrogen transporters and a large group of ABC transporters. Sugar transporters were less represented. CONCLUSIONS: Pathways regulating signalling and intracellular organization were fine tuned whilst cell wall construction and membrane transporter profiles were altered substantially upon transiting to a transfer cell fate. Each phase of ingrowth wall construction was linked with unique cohorts of expressed genes.

As there are numerous pathogen species that cause disease and limit yields of crops, such as wheat (Triticum aestivum), single genes that provide resistance to multiple pathogens are valuable in crop improvement. The mechanistic basis of multi-pathogen resistance is largely unknown. Here we use comparative genomics, mutagenesis and transformation to isolate the wheat Lr67 gene, which confers partial resistance to all three wheat rust pathogen species and powdery mildew. The Lr67 resistance gene encodes a predicted hexose transporter (LR67res) that differs from the susceptible form of the same protein (LR67sus) by two amino acids that are conserved in orthologous hexose transporters. Sugar uptake assays show that LR67sus, and related proteins encoded by homeoalleles, function as high-affinity glucose transporters. LR67res exerts a dominant-negative effect through heterodimerization with these functional transporters to reduce glucose uptake. Alterations in hexose transport in infected leaves may explain its ability to reduce the growth of multiple biotrophic pathogen species.

Cellular pathways of phloem loading in source leaves and phloem unloading in stems of sweet Sorghum bicolor (L.) Moench were deduced from histochemical determinations of cell wall composition and from the relative radial mobilities of fluorescent tracer dyes exiting vascular pipelines. The cell walls of small vascular bundles in source leaves, the predicted site of phloem loading, contained minimal quantities of lignin and suberin. A phloem-loaded symplasmic tracer, carboxyfluorescein, was retained within the collection phloem, indicating symplasmic isolation. Together, these findings suggested that phloem loading in source leaves occurs apoplasmically. Lignin was restricted to the walls of protoxylem elements located in meristematic, elongating and recently elongated regions of the stem. The apoplasmic tracer, 8-hydroxypyrene-1,3,6-trisulfonic acid, moved radially from the transpiration stream, consistent with phloem and storage parenchyma cells being interconnected by an apoplasmic pathway. The major phase of sucrose accumulation in mature stems coincided with heavy lignification and suberisation of sclerenchyma sheath cell walls restricting apoplasmic tracer movement from the phloem to storage parenchyma apoplasms. Phloem unloading at this stage of stem development followed a symplasmic route linking sieve elements and storage parenchyma cells, as confirmed by the phloem-delivered symplasmic tracer, 8-hydroxypyrene-1,3,6-trisulfonic acid, moving radially from the stem phloem.

The significance of the osmotic potential of the seed apoplast sap as a regulator of assimilate transfer to and within coats of developing seed of Vicia faba (cv. Coles Prolific) ... [more]
The significance of the osmotic potential of the seed apoplast sap as a regulator of assimilate transfer to and within coats of developing seed of Vicia faba (cv. Coles Prolific) was assessed using attached empty seed coats and intact developing seed. Following surgical removal of the embryos, through windows cut in the pod walls and underlying seed coats, the resulting attached ¿empty¿ seed coats were filled with solutions of known osmotic potentials (¿0. 02 versus ¿0. 75 MPa). Sucrose efflux from the coats was elevated at the higher osmotic potential (high osmotic concentration) for the first 190 min of exchange. Thereafter, this efflux was depressed relative to efflux from coats exposed to the low osmotic potential (high osmotic concentration) solution. This subsequent reversal in efflux was attributable to an enhanced diminution of the coat sucrose pools at the high external osmotic potential. Indeed, when expressed as a proportion of the current sucrose pool size, relative efflux remained elevated for coats exposed to the high osmotic potential solution. Measurement of potassium and sucrose fluxes to and from their respective pools in the coat tissues demonstrated that the principal, fluxes, sensitive to variative in the external osmotic potential, were phloem import into and efflux from the ¿empty¿ coats. Phloem import, consistent with a pressure-driven phloem transport mechanism, responded inversely with changes in the external osmotic potential. In contrast, sucrose and potassium efflux from the coats exhibited a positive dependence on the osmotic potential. Growth rates of whole seed were approximately doubled by enclosing selected pods in water jackets held at temperatures of 25°C. compared to 15°C. The osmotic potential of sap collected from the seed apoplast remained constant and independent of the temperature-induced changes in seed growth rates and hence phloem import. Based on these findings, it is proposed that control of phloem import by changes in the external osmotic potential observed with ¿empty¿ seed coats has no significance as a regulator of assimilate import by intact seed. Rather, maintenance of the seed apoplast osmotic potential, independent of seed growth rate, suggests that the observed osmotic regulation of efflux from the coats may play a key role in integrating assimilate demand by the embryo with phloem import.

Until recently a suitable experimental system to study sugar unloading from the phloem was not available. Now it is possible to gain a greater insight into this important process using excised seed-coat halves of bean. The technique is described along with three experiments illustrating important characteristics of sugar unloading. Full details of methods are given although the article can be used simply to introduce students to current terminology in phloem physiology, typical 14CO2-dosing techniques in plant studies, and the complex nature of sugar transport across the plasma membrane.

Phloem transport in stems of Phaseolus vulgaris was found to be sensitive to treatment with the auxin transport inhibitor, 2,3,5-triidobenzoic acid (TIBA). The response was dependent on the concentration of TIBA applied. A concentration of TIBA (0·5% in lanolin) which did not interfere with normal phloem transport proved inhibitory to both basipetal transport of IAA and the acropetal component of IAA-promoted metabolite transport. In contrast, both acropetal IAA transport and basipetal IAA-promoted metabolite transport were unaffected by TIBA treatment. The inhibitory effect of TIBA on acropetal IAA-promoted transport was overcome by providing IAA below the point of TIBA application. Both acropetal and basipetal IAA-promoted transport in stem segments were unaccompanied by any corresponding changes in the accumulation of [14C]sucrose by the segments. © 1978 Oxford University Press.

The hypothesis that indol-3yl-acetic acid (IAA) stimulates solute mobilization in stems by increasing metabolite utilization (i.e. sink strength) and/or sieve tube unloading mechanisms was investigated using seedlings of Phaseolus vulgaris L. Sink strength was assessed by obtaining estimates of rates of growth, 14C incorporation into protein, sucrose metabolism, and sucrose uptake. The data obtained suggest that, whilst enhancing assimilate mobilization, IAA had no short term effect on the sink strength of the treated stumps. In several experiments involving long distance transport of 14C-assimilates, the magnitude of auxin-promoted transport was found to be insensitive to potential changes in sink strength. Furthermore, 14C transport profiles demonstrated that the site of hormone action was not confined to its point of application. © 1976 Oxford University Press.

Indol-3yl-acetic acid (IAA) applied to sterns of Phaseolus vulgaris seedlings, decapitated above primary leaves, enhanced the mobilization of 14C-metabolites to the treated stumps and this effect was apparent within 3-6 h of applying the hormone. More than 90 per cent of the total 14C-activity transported to the stumps was detected in the alcohol-soluble extracts. In all treatments, less than 5 per cent of the 14C-photosynthate exported from the primary leaves was translocated upwards. Accumulation of 14C-activity was also increased when the IAA was applied laterally to intact internodes. This effect was obtained when 14C was supplied either above or below the point of hormone application. By selective heat girdling, it was shown that the auxin affected 14C transport when either the root 'sink' was removed or transpiratory flow of water through the treated internode was maintained. Decapitated stems treated with plain lanolin for 3 d were found to retain their responsiveness to auxin in terms of enhanced metabolite transport. Heat-girdling experiments and estimates of 14C transport velocity suggested that most of the 14C movement was restricted to the phloem of treated stumps. Similar effects of IAA on a transport in excised stem segments of Phaseolus vulgaris were observed. © 1973 OXFORD UNIVERSITY PRESS.

Physiological amounts of indol-3yl-acetic acid (IAA) were accumulated by decapitated stems of Phaseolus vulgaris L. seedlings from lanolin pastes, containing 0.1 per cent IAA, applied to the cut surfaces of the stumps. Both the levels and gradients of extractable and diffusable IAA detected in the treated stumps compared favourably with those reported for the whole plants. A considerable portion of IAA that entered the tissue was metabolized to a compound that had chromatographic properties similar to indol-3yl-acetylaspartic acid. Two other metabolities were tentatively identified as indol-3yl-acetylaspartic acid indol-3yl-acetylglucose. The accumulated IAA appears to be transported as indol-3yl-acetic acid at an apparent velocity of 28 mm/h down the decapitated internodes. © 1973 OXFORD UNIVERSITY PRESS.

The sequence of vascular differentiation in the shoot of the main tiller of Triticum aestivum L. was reconstructed from seriai transverse sections of shoot apices made at various stages of development. The pattern of initiation and development of the procambial strands was confirmed. The provascular bundles of the pith plexus arose independently and developed acropetally from the base of the future node. Early differentiation of proto-phloem and -xylem in the main procambial strands proceeded bidirectionally up the leaf primordia and down the stem from a site of initiation isolated from other differentiated vascular elements. Further development was basipetal from the tip of the primordia, and the rate of differentiation of the sieve elements was sufficient to maintain phloem continuity across the intercalary meristems of the laminae, sheaths, and internodes. Within the developing nodes sieve tube differentiation in the cross-linking strands lagged behind that of the leaf traces they interconnected, and this may influence the movement of photoassimilate from a recently expanded leaf to the apex. © 1972 CSIRO.

The courses of the various vascular bundles in the nodes of the main tiller of Triticum aestivum L. have been reconstructed from anatomical observations of consecutive serial transverse sections. Of the bundles entering a node (n) from its attached leaf, the first-formed and largest, the median, passes directly through the node to the second node below (n-2), where it bifurcates and fuses with other strands. These continue to node n-3 before fusing completely with the nodal plexus. The next six bundles to form (laterals) establish some links with bundles from higher leaves in the node of entry, much more extensive connections in node n-1, and fuse completely with the nodal plexus in node n-2. The next four lateral bundles to differentiate are more extensively linked in node n and fuse completely with the nodal plexus in node n - I. The remaining 16-20 bundles from the leaf (intermediates) follow much the same course but develop more extensive connections with other bundles. The extensive plexus which develops in each node ensures vascular connections between most bundles. The significance of these in transport is briefly discussed. © 1972 CSIRO. All Rights Reserved.
