Characterization and Primary Functional Analysis of a Bamboo ZEP Gene from Phyllostachys edulis.


PMID 28686465

Abstract

Zeaxanthin epoxidase (ZEP) plays important roles in plant response to various environmental stresses by involving in abscisic acid (ABA) biosynthesis and xanthophyll cycle. A full-length cDNA of PeZEP was isolated from moso bamboo (Phyllostachys edulis), which comprised of a 138-bp 5'-untranslated region (UTR), a 381-bp 3'-UTR, and a 2013-bp open reading frame (ORF) encoding a putative protein of 670 amino acids. PeZEP was mainly expressed in leaf blades and leaf sheaths, and less in roots and culms. The transcript level of PeZEP in bamboo leaf was elevated with the increasing light intensity. PeZEP was significantly upregulated in response to high light (HL: 1200 μmol·m
