Question

英语翻译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

Answer 1

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.
