چکیده انگلیسی
In seed plants, anthers are critical for sexual reproduction, because they foster both meiosis and subsequent pollen development of male germinal cells. Male-sterile mutants are analyzed to define steps in anther development. Historically the major topics in these studies are meiotic arrest and post-meiotic gametophyte failure, while relatively few studies focus on pre-meiotic defects of anther somatic cells. Utilizing morphometric analysis we demonstrate that pre-meiotic mutants can be impaired in anticlinal or periclinal cell division patterns and that final cell number in the pre-meiotic anther lobe is independent of cell number changes of individual differentiated somatic cell types. Data derived from microarrays and from cell wall NMR analyses allow us to further refine our understanding of the onset of phenotypes. Collectively the data highlight that even minor deviations from the correct spatiotemporal pattern of somatic cell proliferation can result in male sterility in Zea mays.
