Transgenic plant study reveals guard cell phospholipase Dα1 expression reduces water loss and improves seed yield in Brassica napus under drought, highlighting a route to drought-tolerant crops.

Key Points

To determine whether guard cell-targeted expression of Arabidopsis phospholipase Dα1 can reduce water loss and improve drought tolerance and yield in canola.
Engineered two Brassica napus (canola) cultivars to express Arabidopsis PLDα1 driven by the guard cell-specific promoter AtKatIpro.
Evaluated multiple transgenic AtKatIpro::PLDα1 lines for water loss and biomass accumulation under hyperosmotic stress conditions including drought and high salinity.
Assessed seed production of transgenic and wild-type plants grown in field conditions under drought.
Multiple transgenic lines in both cultivars exhibited reduced water loss and increased biomass accumulation under drought and high salinity stress compared to wild-type controls.
Transgenic AtKatIpro::PLDα1 plants produced greater seed yields than wild-type plants in field drought trials.
