Titre : Genomic gymnastics help sorghum plant survive drought

Résumé
A new study provides the first detailed look at how the sorghum plant exercises exquisite control over its genome — switching some genes on and some genes off at the first sign of water scarcity, and again when water returns — to survive when its surroundings turn harsh and arid.

Scorching temperatures and parched earth are no match for the sorghum plant — this cereal crop, native to Africa and Australia, will remain green and productive, even under conditions that would render other plants brown, brittle and barren. A new study published this week in the journal Proceedings of the National Academy of Sciences provides the first detailed look at how the plant exercises exquisite control over its genome — switching some genes on and some genes off at the first sign of water scarcity, and again when water returns — to survive when its surroundings turn harsh and arid.
