与玉米雄性核不育相关的基因MS33及其在杂交育种中的应用
摘要：
本发明公开了一种与玉米雄性核不育相关的基因MS33及其在杂交育种中的应用。本发明提供了一种与玉米雄性核不育相关的MS33蛋白，是如下(a)或(b)：(a)由序列表中序列1所示的氨基酸序列组成的蛋白质；(b)将序列1的氨基酸序列经过一个或几个氨基酸残基的取代和/或缺失和/或添加，且与植物雄性育性相关的由序列1衍生的蛋白质。MS33基因突变导致玉米完全雄性不育，性状彻底，不受环境影响。该基因具有在玉米杂交种子生产上的应用潜力。
摘要（英）：

The invention discloses a gene MS33 related to maize male nuclear sterility and application thereof in cross breeding. The invention provides MS33 protein related to maize male nuclear sterility, which is shown in (a) or (b): (a) protein composed of an amino acid sequence shown in a sequence 1 in a sequence table; or (b) protein which is derived from the sequence 1 by substituting and/or deleting and/or adding one or more amino acid residues on the amino acid sequence of the sequence 1, and related to plant male fertility. MS33 gene mutation causes maize complete male sterility, characters are complete, and environmental influence is avoided. The gene has application potential in maize hybrid seeds.
