MEMORIAL LECTURE: Improving salt tolerance in wheat:
|Improving salt tolerance in wheat: : Discoveries from the search for genes which reduce the rate of sodium accumulation in leaves
In this lecture, internationally renowned and highly cited plant scientist, Prof Rana Munns, will show how the combination of fundamental plant biology and targeted plant breeding can produce significant outcomes for crop production in saline soils.
Saline soils restrict plant growth in a large proportion of the Australian wheat belt. Plants exclude most of the salt from the water they take up from a saline soil, but with time it can build up to high concentrations in older leaves, and kill them. This reduces the supply of carbohydrates to the growing leaves or developing grain.
In a search for genes that reduce the rate of sodium accumulation in leaves, Prof Munns and her team discovered novel genes for controlling sodium transport in an ancestral wheat, crossed them into modern durum wheat, and showed that one of them increased yield in saline soils in farmersí fields by 25%.
