摘　　要：概述了包括赤霉素、成精子囊素、乙烯、细胞分裂素在内的植物激素、培养密度、营养条件、光照条件等环境因素以及配子体自身条件对蕨类植物性别决定的影响,并结合近年来性别决定调控机制在遗传学以及分子生物学方面取得的研究进展,综述了海金沙(Lygodium japonicum)中成精子囊素通过时空分离的赤霉素生物合成途径调控性别的分子机制、水蕨(Ceratopteris richardii)中性别决定遗传学和分子模型以及与性别决定相关的MADS-box基因,指出蕨类植物性别决定调控机制研究需要解决的一系列问题以及未来蕨类植物性别决定的研究方向。Combining with the latest genetic and molecular biological research on sex determinant, the authors in this paper reviewed the influence of environment factors, such as plant hormone （including antheridiogens, ethylene, cytokinin）, nutrient condition, population density, light condition, as well as its own conditions on sex determinant following the introduction of ferns life cycle and summaried the molecular mechanism of antheridiogen determines sex in Lygodiumjaponicum via a spatiotemporally split gibberellin synthesis pathway; the genetic and molecular model of sex-determining pathway in Ceratopteris., MADS-box genes which is related to sex determinant. A series of problems needed to be solved are also pointed out and the research direction in the future are also put forward to provide an effective contribution to elucidate the regulatory mechanism of sex determination in ferns.
