摘　要：

植物早期光诱导蛋白(ELIP)是核编码的叶绿体蛋白, 它属于叶绿素结合蛋白超家族的成员。ELIP基因是一古老的基 因, 在原核细胞中即已存在。真核生物细胞核中的ELIP基因最初可能来源于其质体基因组。目前, 已从30多种不同植物中 克隆到该基因, 研究发现它们多属于胁迫诱导基因, 其功能可能涉及光保护作用。本文介绍了20多年来ELIP基因的克隆、 生物发生、表达调控和功能方面的研究进展, 以期为今后的进一步研究奠定基础。

Abstract:

Early light-induced proteins (ELIPs) are nuclear-encoded thylakoid proteins, and belong to the chlorophyll a/b binding protein superfamily. ELIP genes are thought to be ancient as they have appeared in prokaryocyte. ELIP genes of cell nucleus in eukaryocyte species may come from the genomes of the ancient plastids. Currently, ELIP genes have been cloned from more than 30 plant species, and proven to be stress-induced genes. It has been proposed that they may be involved in photoprotection role of plant leaves. In this paper, it is presented that advances on the study in cloning, biogenesis, expression-regulation and function of ELIP genes in past score years, in order to lay the foundation of further searching ELIPs.

Key words: early light-induced proteins; biogenesis; expression regulation; physiologic function
