Microfluorometric analysis of the nuclear DNA contents of the somatic tissues of Arabidopsis thaliana has revealed extensive endoreduplication, resulting in tissues that comprise mixtures of polyploid cells. Endoreduplication was found in all tissues except those of the inflorescences and was developmentally regulated according to the age of the tissues and their position within the plant.
对拟南芥体细胞组织的核 DNA 含量进行微量荧光分析,发现存在广泛的内复制,导致组织中包含混合的多倍体细胞。内复制存在于除花序以外的所有组织中,并根据组织的年龄及其在植物中的位置进行发育调控。
