Abstract

Abstract: The characterization of a novel gene designated AmZFPG from Ammopiptanthus
mongolicus was described here. AmZFPG encodes a zinc-finger protein that is induced after different types
of stresses，namely cold，desiccation，and salt. Overexpression of the gene in transgenic tobacco conferred
tolerance to cold，dehydration，and salt stress at the seed-germination/seedling stage as reflected by the
percentage of germination，the fresh weight of seedlings，and their growth pattern. Thus，AmZFPG seems
to be an important determinant of stress response.

Key words: Ammopiptanthus mongolicus, AmZFPG gene, transgenetic tobacco, abiotic stress
