基因家族鉴定分析

基因家族（Gene family），是来源于同一个祖先，由一个基因通过基因重复而产生两个或更多的拷贝而构成的一组基因，它们在结构和功能上具有明显的相似性，编码相似的蛋白质产物。同一家族基因可以紧密排列在一起，形成一个基因簇，但多数时候，它们是分散在同一染色体的不同位置，或者存在于不同的染色体上的，各自具有不同的表达调控模式。

研究人员主要关注一些重要的转录因子和酶家族，这些家族成员和生物的生长发育、逆境胁迫、初生代谢和此生代谢的合成、积累、化学修饰以及转运等生物过程息息相关。因此，对基因家族的系统研究，筛选出一个家族中的其关键功能的基因，并预测与之互作或具有调控关系的基因，可以为后期的深入实验验证提供理论指导。也为提高产量、抗性、品质或害虫防控等提供理论基础。
