Ectopic expression of the MYB transcription factor of AmROSEA1 from has been reported to change anthocyanin and other metabolites in several species. In this study, we found that overexpression of significantly improved the tolerance of transgenic rice to drought and salinity stresses. Transcriptome analysis revealed that a considerable number of stress-related genes were affected by exogenous during both drought and salinity stress treatments. These affected genes are involved in stress signal transduction, the hormone signal pathway, ion homeostasis and the enzymes that remove peroxides. This work suggests that the gene is a potential candidate for genetic engineering of crops.
据报道，来自的AmROSEA1的MYB转录因子的异位表达会改变几种物种中的花青素和其他代谢产物。在本研究中，我们发现的过表达显著提高了转基因水稻对干旱和盐胁迫的耐受性。转录组分析表明，在干旱和盐胁迫处理期间，相当数量的胁迫相关基因受到外源的影响。这些受影响的基因参与胁迫信号转导、激素信号通路、离子稳态以及去除过氧化物的酶。这项工作表明该基因是作物基因工程的潜在候选基因。
