摘要: NAC转录因子家族是植物特有的一类重要转录因子,广泛参与植物生长、发育以及器官的建成、逆境胁迫应答等过程。为进一步研究白羊草(Bothriochloa ischaemum) NAC转录因子家族,本研究利用生物信息学方法对白羊草NAC基因所编码的蛋白理化性质、二级结构、保守基序、亚细胞定位、潜在磷酸化位点及系统进化关系进行了分析。结果显示,具有NAC结构域的21条白羊草氨基酸序列共分为10个亚家族,蛋白二级结构以无规则卷曲为主要组成部分,含有5个保守基序,大多数NAC蛋白定位于细胞核,均含有潜在的丝氨酸(Ser)、苏氨酸(Thr)、和酪氨酸(Tyr)磷酸化位点。本研究将为白羊草NAC基因家族的进一步功能分析奠定重要的研究基础。

Abstract: NAC gene family encode a kind of plant specific important transcriptional factors,which are involved extensively in plant growth,development and organogenesis and stress responses. However,up to date,little is known about NAC genes in Bothriochloa ischaemum. Hence,by utilizing the bioinformatics method,we analyzed the physical and chemical characteristics of encoding proteins,conserved motif,subcellular localization,potential phosphorylation sites and evolutionary relationship of 21 NAC family protein sequence from B. ischaemum. The result showed that these 21 amino acid sequences could be clustered into ten groups. The secondary structure of NAC genes was mainly random coil,containing 5 conserved motifs. Most of the NAC proteins were located in the nucleus,and potential phosphorylation sites analysis indicated that all NAC proteins contain Ser,Thr and Tyr phosphorylation sites.These results of this investigation could definitely provide a significant foundation for further research on the functional analysis of Bothriochloa ischaemum NAC gene family.
