玉米衰老相关基因在2个杂交种及其亲本中的表达分析
Expression analysis of senescence-associated genes in maize in two different hybrids and its parent lines
摘要
Abstract
Maize hybrid Xianyu 335 and Zhengdan 958 as well as its parent lines were employed to analyze the expression pattern of senescence related gene in the development of leaves and embyro.The results showed that two stay-green genes SGR1 and SGR2 were up regulated in hybrid Xianyu 335 and Zhengdan 958 together with its parent lines with age,and the gene expression level in Xianyu 335 was higher than that in Zhengdan 958.Senescence associated gene SAP1 was up expressed in the leaves development process,and the expression of SAP2 was increased first and then decreased with the leaves development stages.Three embyro senescence associated genes,SAG1,SAG2 and SAG3,were analyzed in different growth period,and the results showed that SAG1 was down regulated after fertilization,while SAG2 and SAG3 were up-regulated.关键词
