Résumé
Flowering is a prerequisite for pear fruit production. Therefore, the development of flower buds and the control of flowering time are important for pear trees. However, the molecular mechanism of pear flowering is unclear. SOC1, a member of MADS-box family, is known as a flowering signal integrator in Arabidopsis. We identified eight SOC1-like genes in Pyrus bretschneideri and analyzed their basic information and expression patterns. Some pear SOC1-like genes were regulated by photoperiod in leaves. Moreover, the expression patterns were diverse during the development of pear flower buds. Two members of the pear SOC1-like genes, PbSOC1d and PbSOC1g, could lead to early flowering phenotype when overexpressed in Arabidopsis. PbSOC1d and PbSOC1g were identified as activators of the floral meristem identity genes AtAP1 and AtLFY and promote flowering time. These results suggest that PbSOC1d and PbSOC1g are promoters of flowering time and may be involved in flower bud development in pear.
