摘要:

OVATE家族蛋白(OFPs)是一类植物中特有的调控生长发育的蛋白,在一些物种中已经被研究报道,但在黄瓜中的生物学功能还不清楚。我们在黄瓜中鉴定出19个CsOFPs。这些基因在黄瓜的7条染色体上均有分布。大多数在生殖器官中有表达,但表达模式具有差异性。在拟南芥中异源过表达CsOFP12-16c导致果实变短,末端钝圆。以上研究表明CsOFP12-16c在拟南芥中调节角果的发育,在黄瓜中可能参与了果实形状的调控。


Abstract: OVATE family proteins (OFPs) are plant-specific proteins with a conserved OVATE domain that regulate plant growth and development.  Although OFPs have been studied in several species, their biological functions remain largely unknown in cucumber (Cucumis sativus L.).  This study identified 19 CsOFPs distributed on seven chromosomes in cucumber.  Most CsOFP genes were expressed in reproductive organs, but with different expression patterns.  Ectopic expression of CsOFP12-16c in Arabidopsis resulted in shorter and blunt siliques.  The overall results indicated that CsOFP12-16c regulates silique development in Arabidopsis and may have a similar function in cucumber.
