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.
