Abstract

Abstract: The exogenous DkERF9，a reported hypoxia responsive gene from persimmon，was transformed into‘Jiuyuejiu’chrysanthemum. Five positive lines（35S::DkERF9）were obtained and verified with PCR. Compared to the wild type plants，the growth of 35S::DkERF9 lines were inhibited significantly by water planting treatments for two weeks，as the length of roots and shoots were shorter in 35S::DkERF9 lines. The differences between 35S::DkERF9 lines and wild type plants remain significant，after three weeks recovery.

Key words: chrysanthemum, ERF, waterlogging, hypoxia, transformation
