S7 Description: Perennial shrub to 2 m tall and 4 m wide (although generally smaller) that can be prostrate or erect. Stems touching the ground may form roots. Leaves 1 cm to about 3 cm long. Generally, male and female flowers on separate plants (dioecious) (see photo). Fruits woody or papery 2–6 mm wide. Flowering is variable depending on seasonal conditions. Key features: Leaves variable in shape but often characteristically spear-shaped (see photo). Value: Low to moderate energy value—at best it only provides maintenance for dry sheep. Moderate crude protein and up to 25% salt in leaves. Some supplements (grain, pasture or hay) and good quality drinking water are essential. River Saltbush is more palatable to sheep than other livestock. Once established, extremely tolerant of heavy grazing for short periods of time. Salinity and waterlogging tolerance: Moderate to high salinity tolerance and high drought tolerance. Once established it can tolerate winter waterlogging surviving several weeks of flooding in winter. Notes: Native of Gascoyne and Murchison area of WA. Seed harvested in late summer. Sometimes difficult to establish by seed. Readily grows from stem pieces. Commonly sown in mixtures with other saltbushes (especially in WA).

Functional Role of Betalains in Disphyma Australe Under Salinity Stress
FUNCTIONAL ROLE OF BETALAINS IN DISPHYMA AUSTRALE UNDER SALINITY STRESS BY GAGANDEEP JAIN A thesis submitted to the Victoria University of Wellington In fulfillment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington (2016) i “ An understanding of the natural world and what’s in it is a source of not only a great curiosity but great fulfillment” -- David Attenborough ii iii Abstract Foliar betalainic plants are commonly found in dry and exposed environments such as deserts and sandbanks. This marginal habitat has led many researchers to hypothesise that foliar betalains provide tolerance to abiotic stressors such as strong light, drought, salinity and low temperatures. Among these abiotic stressors, soil salinity is a major problem for agriculture affecting approximately 20% of the irrigated lands worldwide. Betacyanins may provide functional significance to plants under salt stress although this has not been unequivocally demonstrated. The purpose of this thesis is to add knowledge of the various roles of foliar betacyanins in plants under salt stress. For that, a series of experiments were performed on Disphyma australe, which is a betacyanic halophyte with two distinct colour morphs in vegetative shoots. In chapter two, I aimed to find the effect of salinity stress on betacyanin pigmentation in D. australe and it was hypothesised that betacyanic morphs are physiologically more tolerant to salinity stress than acyanic morphs. Within a coastal population of red and green morphs of D. australe, betacyanin pigmentation in red morphs was a direct result of high salt and high light exposure. Betacyanic morphs were physiologically more tolerant to salt stress as they showed greater maximum CO2 assimilation rates, water use efficiencies, photochemical quantum yields and photochemical quenching than acyanic morphs.

Perennial Shrubs: Production, Grazing and Recovery in the Mallee
Invited article Perennial shrubs: production, grazing and recovery in the Mallee Dr. Dave Monks (Victorian DPI) Take home messages • Atriplex and Rhagodia species fared best in these experiments, producing the highest biomass on offer to sheep, plant survival rate and health scores. However, the Rhagodia species consistently demonstrated low stock grazing preference and of the Atriplex species, only A. vesicaria and A. cinerea were shown some preference by sheep • four species showed poor adaptation to the environment at Walpeup and produced little edible biomass, namely Atriplex semibaccata, Convolvulus remotus, Cullen australasicum and Medicago strasseri. Grazers often exhibited greatest preference for these species, which is likely to have contributed to their swift exit from the experiment • results from this experiment and others across the nation have led to establishment of a new site at Manangatang to demonstrate the most promising species for the Mallee region’s poorer soils Background In 2008, the Mallee Catchment Management Authority (CMA) funded the establishment of an Enrich shrub evaluation experiment at Walpeup Research Station, with the support of the Department of Primary Industries. Native shrubs have potential for biomass production and grazing in these areas where alternative perennial options are limited. Deep rooted perennials have also been identified as having the most impact on improvement of ecological stability by reduction of groundwater recharge and salinity. Aim This shrub experiment is an initiative of the Future Farming Industries CRC and aims to explore use of perennial shrubs as a feed source for profitable and sustainable grazing systems in low-to-medium rainfall areas of the Mallee.

Eissa Department of Soils and Water, Faculty of Agriculture, Assiut University, Assiut 71526, Egypt Abstract: Chenopod shrubs accumulate Na, K and Cl. There is little information available on the factors affecting the accumulation of these and other minerals in these plants. A field experiment was conducted out to study the accumulation of Na, Cl, K, N, Ca, P, Mg, Cu, Zn, Cd, Pb and Mn in Atriplex amnicola grown on contaminated soils. Compost at rates of 0, 15 and 30 ton ha 1 was used to assay its role in plant growth and nutrient uptake. Compost application significantly increased N and P concentrations in the shoots of river saltbush; on the other hand it decreased Zn and Pb concentrations. Biomass yield, crude protein and ash content of river saltbush increased significantly by compost application. Despite the extremely high total micronutrients and heavy metals concentrations in the studied soil, river saltbush plants were able to maintain shoot elements below the toxic level. Contaminated soils can be managed by planting A. amnicola together with compost addition. Key words: INTRODUCTION maintain Hms in solution through the formation of low-molecular-weight organometallic complexes [6]. Halophytes are plants that can tolerate and grow on There is little information about many species of soils having high salt concentration and be irrigated with Atriplex grown in contaminated soils also the response the highly saline water.

Exploring the Biochemical and Phylogenetic Fingerprint of Australian Native Plants for Sustainable Use of Saline Lands
Exploring the biochemical and phylogenetic fingerprint of Australian native plants for sustainable use of saline lands Shanthi Safrina Maria Monica Joseph (MSc Biotechnology) This thesis is presented for the degree of Doctor of Philosophy March 2014 Department of Chemistry and Biotechnology Faculty of Science, Engineering and Technology Swinburne University of Technology Melbourne, Australia Abstract The remarkably rich Australian native vegetation has developed some unique morphological and genetic mechanisms to adapt to severe drought, salinity and water logging. However, the utilisation and significance of Australian native plant bio- resources has been under-exploited, with relatively few dedicated studies, particularly in comparison to crop plants such as rice, wheat or barley. This project investigated the unique gene pool of certain Australian salinity-tolerant plants (three saltbushes- Atriplex nummularia, A. semibaccata, A. amnicola and four Acacia species- Acacia victoriae, A. salicina, A. pendula and A. stenophylla). The osmoprotectants glycine betaine (GB), proline and trehalose known to impart salt tolerance were investigated in these plants. Genes encoding the enzymes choline monooxygenase (CMO) and betaine aldehyde dehydrogenase (BADH) involved in GB biosynthesis were identified in the three saltbushes. In-silico analyses of their cDNA sequences and predicted proteins revealed valuable predictive data pertaining to their extremely conserved functional and structural motifs, subcellular localisation and physico-chemical properties. Gene expression analyses indicated that the saltbush genes for CMO and BADH were differentially expressed in leaves and roots, with significant up-regulation (>1.5 fold change) of CMO and/or BADH mRNA in the leaf tissues indicating that these genes serve as ideal candidates in transgenic work to enhance salt tolerance in salt sensitive plants.

Taxonomic Resolution of Atriplex Sp. Yeelirrie Station (L
FINAL REPORT Commissioned by BHP Billiton Yeelirrie Uranium Project Taxonomic resolution of Atriplex sp. Yeelirrie Station (L. Trotter & A. Douglas LCH 25025) utilising morphological and molecular methods Prepared by Kelly A. Shepherd, Jane Sampson, Kevin Thiele and Margaret Byrne Science Division Department of Environment and Conservation Locked Bag 104, Bentley Delivery Centre Western Australia 6983 Email: [email protected] Taxonomic resolution of Atriplex sp. Yeelirrie Station Summary Atriplex sp. Yeelirrie Station (L. Trotter & A. Douglas LCH 25025) is supported as a distinct taxon differing from other known species of Atriplex based on both morphological and molecular evidence. A molecular study using AFLP markers did not detect a significant genetic difference between two morphotypes (adorned and unadorned fruits) present within A. sp. Yeelirrie Station. However, the two known populations of A. sp. Yeelirrie Station were found to be genetically remarkably distinct. This is congruent with recent findings in a concurrent population-level analysis using microsatellites by Clarke et al. (2011). It is unclear if the difference between the two populations of A. sp. Yeelirrie Station supports the recognition of two distinct taxa. The level of differentiation observed is similar to that identified between two subspecies of the related A. nummularia (Sampson & Byrne, 2011). Project Aim Resolution of the taxonomic status of Atriplex sp. Yeelirrie Station (L. Trotter & A. Douglas LCH 25025) and clarification of genetic diversity between morphotypes within this Priority One putative taxon, to inform environmental impact assessment processes. Project Background Atriplex sp. Yeelirrie Station (L. Trotter & A. Douglas LCH 25025) is a perennial, dioecious shrub currently known from two populations approximately 30 km apart on Yeelirrie Station, 60 km west of the BHP Billiton Mt Keith Nickel Operation.
