TLDR
The results showed that from small bud → middle bud → big bud, the content of IAA and ZT in CMS buds were higher than in maintainer line buds, and it was suggested that the changes of endogenous hormone contents were closely related with the occurrence of cytoplasmic male sterility.Abstract:
The dynamic changes of the indole acetic acid(IAA), gibberellin(GA-3),zeatin(ZT) and abscisic acid(ABA) contents in flower buds of tobacco cytoplasmic male sterility(CMS) and homolog maintainer lines were determined by high-performance liquid chromatogram.The results showed that from small bud → middle bud → big bud,the content of IAA and ZT in CMS buds were higher than in maintainer line buds.While the content of GA-3 and ABA in CMS buds were lower than in maintainer line buds.It was suggested that the changes of endogenous hormone contents were closely related with the occurrence of cytoplasmic male sterility.read more

TL;DR: A stably inherited male sterile mutant msm was obtained from the ‘FT’-doubled haploid line of Chinese cabbage using isolated microspore culture combined with 60Co γ-ray mutagenesis, indicating that the msm mutant phenotype is controlled by a single recessive nuclear gene.
