植物谷胱甘肽过氧化物酶（GPX）家族由多个同工酶组成，它们具有不同的亚细胞位置、组织特异性表达模式和环境胁迫反应。本研究从棉花（Gossypium hirsutum, GhGPXs）基因组中鉴定出13个推测的GPXs，发现它们在植物GPXs中具有保守模式，并且对多种环境胁迫有响应，我们预测它们的启动子区域具有激素响应的顺式元件。大多数在酵母中表达的GhGPXs都能清除H2O2。我们的研究结果表明，GhGPX基因家族的不同成员在特定的环境胁迫条件下协同调节，提示GhGPX在激素治疗和非生物胁迫应答中的重要性。
The plant glutathione peroxidase (GPX) family consists of multiple isoenzymes with distinct subcellular locations, tissue-specific expression patterns and environmental stress responses. In this study, 13 putative GPXs from the genome of Gossypium hirsutum (GhGPXs) were identified and a conserved pattern among plant GPXs were exhibited, besides this they also responded to multiple environmental stresses and we predicted that they had hormone responsive cis-elements in their promoter regions. Most of the GhGPXs on expression in yeast can scavenge H2O2. Our results showed that different members of the GhGPX gene family were co-ordinately regulated under specific environmental stress conditions, and suggested the importance of GhGPXs in hormone treatments and abiotic stress responses.
