| 摘 要： | 异戊烯基转移酶是细胞分裂素生物合成第一步的催化酶,也是限速酶。其编码基因ipt已被克隆,运用生物信息学方法,在拟南芥中鉴定出与微生物同源的编码异戊烯基转移酶的基因家族,推测这些基因可能存在特殊时空表达来调控细胞分裂素的合成途径。本文着重介绍ipt在细胞分裂素合成中的作用和研究进展。

| Abstract: | Isopentenyl-transferases catalyze the first and rate-limiting steps of cytokinin biosynthesis, and the corresponding genes have been cloned. A family of genes from Arabidopsis coding for cytokinin biosynthesis enzymes have been identified by a bioinformatic approach. It is speculated that these genes might be expressed in distinct spatial and temporal patterns to regulate cytokinin biosynthesis. This review specially introduced the functions and advances of ipt in cytokinin biosynthesis. |
