| 摘 要： | Aux/IAA基因家族是一个典型的被生长素诱导而表达的基因家族,可以被生长素快速诱导表达。采用生物信息学方法在黄瓜基因组中确定了28个Aux/IAA基因,除4号染色体外,其他6条染色体均有分布,编码蛋白序列在70~427个氨基酸残基之间,22个黄瓜Aux/IAA蛋白具有完整的4个保守结构域,进化方式多样化。该研究结果有助于黄瓜生长素信号转导途径的解析。

| Abstract: | Aux/IAA genes are typical gene family induced by auxin. Their expression can be induced rapidly by auxin. We identified 28 Aux/IAA genes by using bioinformatics methods in the cucumber genome database. They are distributed on the 6 chromosomes except on the 4th of 7 chromosomes of cucumber,their encoding protein sequences are between the 70427 amino acid residues and 22 cucumber Aux/IAA proteins have four complete conserved domains,which showed their evolutionary diversification. The study will not only hel... |
