摘要:
NRL(NPH3/RPT2-like)蛋白是植物特有的光响应蛋白家族,其成员在调节植物气孔开放、叶绿体运动、叶片伸长和向光性等方面起着重要作用。为探究甜瓜NRL家族基因结构、染色体位置及其编码蛋白质的理化性质、保守基序,弱光胁迫下甜瓜NRL家族基因的表达特征,本研究通过生物信息学手段,对甜瓜NRL家族基因进行鉴定。结果表明,甜瓜全基因组中存在24个NRL家族成员,分布在除5号染色体外的其他11条染色体上。甜瓜NRL家族基因结构较为保守。20个CmNRL家族基因在茎和叶中高表达,在根中表达水平较低,15个CmNRL家族基因可能参与甜瓜对弱光胁迫的响应。本研究结果可为甜瓜NRL家族基因功能研究和利用提供参考和依据。
Abstract:
The NRL (NPH3/RPT2-like) protein is a plant-specific light-responsive protein family, and its members play important roles in regulating plant stomatal opening, chloroplast movement, leaf elongation and phototropism. In order to explore the structure and chromosomal location of NRL family genes of Cucumis melo L., and physicochemical properties and conserved motifs of their encoded proteins, and the expression characteristics of melon NRL family genes under low light stress, this study identified melon NRL family genes by bioinformatics methods. The results showed that there were 24 NRL family genes in the whole genome of melon, which were distributed on 11 chromosomes except chromosome 5. The NRL family gene structure of melon was relatively conservative. The 20 CmNRL family genes were highly expressed in stems and leaves, and the expression level in roots was low. The 15 CmNRL family genes may be involved in the response of melon to low light stress. The results of this study can provide reference and basis for the functional research and utilization of melon NRL family genes.
