Description
Liqun Tang and six colleagues show that a rice transcription factor, OsbZIP60, strengthens the plant against salty soil. Salinity limits rice growth and harvests worldwide. The bZIP family of regulators coordinates stress responses, but this member's role was uncharacterized. The gene is switched on in all rice tissues, and its protein sits in the cell nucleus. Salt, drought-like osmotic stress, and stress hormones all raise its activity.
Plants engineered to overproduce the factor tolerated salt far better. Plants with the gene knocked out became hypersensitive. Protected plants stockpiled osmoprotectant molecules, suffered less oxidative injury, and ran their antioxidant enzymes hotter. The twenty twenty-six findings nominate OsbZIP60 as a breeding or engineering target for rice grown on salinized land, an expanding problem as irrigation and seas encroach.
