Abstract: A total of 54 MADS-box genes were identified from the grape genome,including 10 Type-Ⅰand 44 Type-Ⅱgenes. All of them distributed on 15 chromosomes,encoded protein sequence was 62–596 amino acids,and the number of exons 1–16 pieces. The promoter region contains a large number of related functional domains such as light signal,plant hormone,stress and meristem. According to the results of qRT-PCR,the expression level of SEP,FUL,FLC,SVP,SOC1 and ANR1 gradually increased with the leaves growth,reaching the highest in mature leaves,then decreased in old leaves;the first fruit expansion period and fruit color change period are the two peak expression stages of SEP,SOC1 and ANR1 subclass genes;hydrogen cyanamide treatment induced the expression of SVP,AGL15,SOC1,AP3/PI,AGL12 and FLC subclass genes to increase continuously during dormancy and decrease during dormancy release.
