小麦叶片生长发育是受基因调控的 ,到了一定阶段衰老基因就开始启动、表达 ,叶片开始衰老 ,人们已经分离出一系列与衰老有关的基因[1] 。细胞核是细胞内最大的细胞器 ,载有全部基因组的染色体 ,它是基因复制、RNA转录的中心。衰老过程是细胞死亡的一种形式 ,具有独特的形态学特
The growth and development of wheat leaves are regulated by genes. At a certain stage, the senescent genes are started, expressed and the leaves begin to age. A series of genes related to aging have been isolated [1]. The nucleus, the largest organelle in a cell, contains the entire genome of a chromosome, which is the center of gene transcription and RNA transcription. Aging is a form of cell death that has unique morphological characteristics
