摘要: 为了进一步了解MADS-box家族基因的功能,利用生物信息学的手段,首次对甜菜MADS-box基因进行了全基因组的鉴定,并对其染色体定位、系统发生关系、基因结构、保守元件、表达模式以及蛋白功能联系进行预测和分析。结果表明,甜菜MADS-box基因共34个成员,其中,type Ⅰ成员7个和type Ⅱ成员27个,type Ⅰ进一步分为Mα(3)、Mβ(1)、Mγ(3)3个组;type Ⅱ进一步分为MIKCC(22)和MIKC*(5)2个组,MIKCC组可进一步分为AG (2)、AGL12(2)、AP3-PI (4)、Bs (2)、SOC1(1)、SVP (1)、SEP (3)、AGL17(5)、AP1-FUL (1)和FLC (1)10个亚组。MADS-box家族基因在染色体上呈不均匀分布,同一染色体上的基因簇状分布,其中,第6号染色体上分布最多,在第7号染色体上没有分布。甜菜MADS-box家族基因虽然基因结构差别较大,但蛋白序列相对保守。基因表达谱显示,大部分MADS-box基因优势表达于分生组织,部分MADS-box基因在种子、直根、幼叶等组织亦有较高表达。部分MADS-box基因响应盐、热胁迫轻微上调,可能参与甜菜逆境生理调控。

Abstract: To further understand the function of MADS-box family gene,the genome-wide of beet MADS-box genes were first identified by bioinformatics,and chromosomal localization,phylogenetic relationship,gene structure,conserved domain,expression pattern and proteins function connections were predicted and analyzed.The results showed that there were 34 MADS-box genes in beet,among which 7 members belong to type Ⅰ and 27 members belong to type Ⅱ.Type Ⅰ was further divided into three class:Mα (3),Mβ (1) and Mγ (3),type Ⅱ was further divided into two class:MIKCC (22) and MIKC* (5),and MIKCC class were further divided into ten subclass:AG (2),AGL12 (2),AP3-PI (4),Bs (2),SOC1 (1),SVP (1),SEP (3),AGL17 (5),AP1-FUL (1) and FLC (1).The MADS-box genes showed uneven distribution on the chromosome,and genes cluster distribution on one chromosome.The most distributed was on chromosome 6,none on chromosome 7.The structure of the MADS-box genes was different,but the protein sequences were conserved relatively.The expression profile showed that most MADS-box genes were expressed highly in meristem,and some MADS-box genes were expressed advantageously in seeds,roots,young leaves,and so on.Some MADS-box genes are slightly up-regulated in response to salt or heat stress and may be involved in the physiological regulation under stress.
