Abstract
Summary: Though plant meiotic mutants have been isolated and analyzed for along time, molecular analyses of plant meiosis have practically begun when new technologies, transposon or T-DNA tagging methods, became available for such area of plant researches. By these methods, many meiotic tagged mutants were isolatedfrom Arabidopsis and other plants. At the same time, recent cytological methods, such as FISH(fluorescence in situ hybridization)and fluorescent immunohistochemistry, provided more specific analyses of meiotic mutants, which enabled us to study chromosome behavior and protein localization during meiosis in detail. Along with accumulation of knowledge about meiosis of different organisms, combined application of the two techniques has accelerated the progress of plant meiosis research since 1998. In this paper, concentrating on the tagged mutants of meiosis and their analytical methods, recent results of plant meiosis study will be summarized.
