【摘要】：植物B-box基因參與植物形態(tài)建成、花器官發(fā)育以及響應(yīng)逆境脅迫過程中的多種生命活動的并具有重要作用,草莓是重要的經(jīng)濟(jì)果樹作物,然而對草莓B-box家族了解較少。為了研究草莓B-box基因家族成員及其在花器官發(fā)育過程中的表達(dá)情況,本研究利用計算生物學(xué)的方法從全基因組水平鑒定森林草莓(Fragaria vesca)B-box基因家族成員,并對家族成員的蛋白質(zhì)特征、基因組分布、內(nèi)含子個數(shù)以及基因表達(dá)進(jìn)行分析。結(jié)果表明,森林草莓中至少存在21個B-box基因家族成員,分布在6條染色體上,基因內(nèi)含子個數(shù)1~5個。基于蛋白質(zhì)模體組成與蛋白質(zhì)序列的分析將整個家族分為五個亞家族。14個基因家族成員以5種表達(dá)模式參與雄蕊器官發(fā)育進(jìn)程。研究結(jié)果表明:草莓B-box基因家族的5個亞家族經(jīng)過模體復(fù)制和刪除事件進(jìn)化而來,并參與花器官發(fā)育過程。試驗結(jié)果將為在草莓中進(jìn)一步研究該基因家族成員功能提供參考。
[Abstract]:Plant B-box gene is involved in plant morphogenesis, flower organ development and a variety of life activities in response to stress. Strawberry is an important economic fruit tree crop, but little is known about strawberry B-box family. In order to study the members of strawberry B-box gene family and their expression during floral organ development, the members of forest strawberry (Fragaria vesca) B-box gene family were identified by computational biology at the whole genome level. The protein characteristics, genome distribution, intron number and gene expression of family members were analyzed. The results showed that there were at least 21 members of B-box gene family in forest strawberry, distributed on 6 chromosomes, and the number of introns in the gene was 1 鈮，
