PubMedRice feeds more than half the world's population, and the salty, degraded farmland spreading across Asia and Africa could soon grow the food you eat — these genes are a key to making that possible.
Rice plants have a set of 'switch' genes that help them sense and respond when the soil around them gets too salty. Researchers mapped out this whole gene family in rice and dug into what one of them actually does when salt stress hits. Understanding these switches could help scientists breed tougher rice that thrives on land that's currently too salty to farm.
Key Findings
A genome-wide scan identified the complete ARR-B (B-type response regulator) gene family in rice for the first time
At least one ARR-B gene was functionally characterized and shown to play a role in the rice plant's response to salinity stress
Salinity stress is identified as a primary environmental factor severely limiting rice productivity globally
chevron_right Technical Summary
Scientists identified a family of genes in rice that help the plant respond to salt stress, potentially opening new paths to breed rice varieties that can grow in salty soils where most crops fail.

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
