Abstract excerpt

The autophagy-related protein COST1 (constitutively stressed 1) is essential for the normal growth and response to abiotic stress via modulating the autophagy pathway in plants. However, the biological functions of COST family proteins in graminaceous crops like rice in response to salt stress remain uncharacterized. Here, OsCOST1 RNAi lines were generated. Knockdown of OsCOST1 expression enhanced the salt...
