Preliminary field trial results suggest barley over-expressing AVP1 has greater shoot biomass and grain yield in a saline field than barley plants without AVP1.. The aim of the project was to evaluate the shoot growth and grain yield of barley over-expressing AVP1 in a saline field to test whether or not this gene is able to improve the salinity tolerance of this cereal crop... Preliminary results suggest that the over-expression of AVP1 improves the growth of barley leading to an increase in shoot biomass and grain yield in a saline field...

Phylogenetic tree of plant NHX proteins showing the evolutionary relationship of canola (BnNHX6), Brassica oleracea (BoNHX6) and Brassica rapa (BrNHX6) to other plant NHX proteins... The most common strategy is to actively transport excess Na+ ions out of the cell, or to sequester the Na+ ions in internal compartments (Hasegawa et al., 2000)... Figure 2 shows different stages of lateral root formation in WT plants (A - C), note the regular cell division and uniform rounded shape of the developing lateral root (A, B open triangles) in the nhx5 nhx6 double mutant there is a lack of clear cell division (D-F), the individual cells have a bubbly appearance (D) and the developing lateral root primordia has a non uniform concave like appearance (F filled triangle)...

" Quantifying the relative contribution of physiological traits contributing to salinity tolerance in barley and wheat.. Over the past decades, breeding for salinity tolerance both in Australia and worldwide was essentially empirically-driven and relied mainly on plant phenotyping under field or glasshouse conditions... Given the complexity and plethora of physiological and genetics mechanisms conferring salinity tolerance in plants, the practical outcomes of such approaches are disappointingly low...

Soil acidity, salinity, waterlogging, drought and frost are key factors limiting barley growing areas and sustainability of production in Australia... Australian barley lacks genetic variation for tolerance to these stresses... The proposal focuses on (1) screening 1000 barley accessions for acid soil, drought, frost or salinity tolerance in China, (2) identification and characterization of new genes from the Chinese germplasm for abiotic stress tolerance, and (3) introduction and evaluation of 100 barley accessions in Australia...
