水稻花器官发育不仅是形成水稻产量和稻米质量的基础,同时也是一个非常复杂的生物学过程,已有研究表明：OsMADS1和OsMADS6在水稻花器官的形成过程中起到了举足轻重的作用,其中,突变体Osmads1的内外稃不能紧密闭合并且内外稃伸长成为叶片状结构,雄蕊数目减少,花药变小花丝变短；Osmads6-5的外稃基本正常,内稃变厚,其内三轮花器官完全退化并且被大量的类似于稃片状的器官所取代.为了进一步分析这两个基因在水稻花器官中的作用机理以及突变时的相互关系,通过构建一个Osmads1+Osmads6-5双突变体,观察其表型以及石蜡切片,结果发现Osmads1+Osmads6-5的内外稃与Osmads1单突变体的内外稃基本相似,伸长呈叶状,其内三轮花器官不能够正常发育,浆片形成类似稃片的器官,最终形态变为水稻花中带着小穗即典型的“花中穗”的形态.

Rice floral organ development is not only the basis for the formation of grain yield and grain quality of rice,but also a very complex biological process,studies have shown that:the formation of OsMADS1 and OsMADS6 in rice in floral organs play a decisive role,which,mutant Osmads1 lemma and palea not tightly closed elongation become blade structure,fewer stamens,anther variable floret silk shorter; Osmads6-5 lemma and palea basically normal,thicker,completely degraded and replaced by a lot of similar to lemma patchy organ of floral organs in the round.In order to further analyze the relationship between the two genes in rice flower organ and mechanism of mutation,by constructing a Osmads1+Osmads6-5 double mutant,observe the phenotype and paraffin section,the lemma palea and the Osmads1 single mutant Osmads1+Osmads6-5 were basically similar,elongation was leaflike,can not be normal floral organ development in the in the round,lodicule formation similar lemmas organs,eventually form into a rice flower with a spike that is typical of the "flower spike" morphology.
