The phenotypes of T-DNA insertion mutants of OSR genes were screened under different abiotic stresses, and the mutants for 4 OSR genes were found to be more sensitive to drought stress than wild type plants.

• 对OSR家族基因的T-DNA插入纯合突变体进行表型分析的结果表明,该家族中有4个基因的突变体表现出对干旱胁迫敏感的性状,包括在干旱胁迫处理下较早萎蔫、复水后生存率较野生型低等。
