In order to study the role in the process of drought resistance and salt tolerance of S-adenosylmethionine decarboxylase in Hibiscus cannabinus. We obtained the key fragment of SAMDC gene through screening kenaf transcriptome database, SAMDC gene named HcSAMDC was isolated using chromosome walking technology. The coding sequence of HcSAMDC gene has a length of 1 137 bp, which encod 378 amino acid, molecular weight is41.8 k D, isoelectric point is 4.86, HcSAMDC gene has high similarity with other species, am...
干旱、盐碱和极端温度等是目前世界范围内严重影响作物生长发育和产量形成的主要非生物因素(Fang and Xiong,2015;Zhang et al.,2015;翁宇和戴小枫,2008)。多胺是生物代谢过程中产生的具有生物活性的脂肪族含氮碱,在植物的性型分化、形态建成以及对外界生物逆境和非生物逆境反?
