【摘要】：拟南芥At PRXs基因家族属于过氧化物酶类,在植物木质素形成过程中发挥了重要的作用。本研究对ATPRX在大豆中的同源基因Glyma06g28890进行基因结构功能预测和表达分析,发现了Glyma06g28890和At PRXs相同,具有一个保守的Plant peroxidase结构域,并且与ATPRX25具有最高的相似度;通过启动子顺式作用元件统计,发现在基因启动子序列中含有厌氧诱导调节、激素响应、分生组织表达以及植物防御相关的元件。Glyma06g28890在大豆的组织特异性表达分析结果表明,它在植物内木质素广泛分布的组织内,如根和茎内都有较高水平的表达。
[Abstract]:The at PRXs gene family of Arabidopsis thaliana belongs to peroxidase and plays an important role in the formation of plant lignin. In this study, the gene structure and function of homologous gene Glyma06g28890 of ATPRX in soybean were predicted and expressed. It was found that Glyma06g28890 and at PRXs share the same Plant peroxidase domain and have the highest similarity with ATPRX25. Through the statistics of cis-acting elements of promoter, it is found that the promoter sequence contains anaerobic-induced regulation and hormone response. The results of tissue specific expression analysis of Glyma06g28890 in soybean showed that Glyma06g28890 had a high level of expression in the tissue where lignin was widely distributed in plants, such as roots and stems.
