Research progress on the relationship between anther wall tissue and male infertility
Male infertility has always been a hot research topic in the field of plant reproductive biology,in-volving in-depth and systematic analysis of epigenetics such as gene regulation of nuclear and cytoplas-mic infertility,as well as genome-wide DNA methylation and histone modifications.The development of microspores is closely related to the anther wall layers.Due to the dysfunction of anther wall cells and some physiological and genetic factors,microspores in anthers can not develop normally,which leads to abortion.Previous studies on male sterility have been carried out in depth,mainly involving the transcrip-tional regulation of nuclear sterility genes,molecular regulation of cytoplasmic male sterility,genome-wide DNA methylation and histone modification and other epigenetic modification tools.In recent years,there is a lack of systematic reports on the effect of anther wall layer on microspores.In this paper,the latest re-search findings on anther wall development of herbaceous model plants and crops are reviewed,in order to provide clues and ideas for further research on the molecular mechanism of anther wall development,microspore development and degradation,hybrid seed production or breeding research.
