Abstract

Phosphoglucomutases (PGM) (5.4.2.2.) belong to the Phosphohexomutases superfamily and are highly specific in catalyzing the interconversion of Glc-1-P to Glc-6-P. In this study, we characterize the expression and activity of two cytosolic PGMs (cPGM2 and cPGM3) stigmas of ornamental kale during flower development. In stigmas, cPGM expression and activity showed a gradual increase during stigma development with the highest activity around the time of anthesis. Blocking of cPGM activity in the stigmas using a known inhibitor, resulted in breakdown of self-incompatibility in immature S3 and S4 stigmas, but had no effect on the fully mature S5 stigmas. It is likely that cPGMs are required for accumulation of factors necessary for SI response in mature stigmas.

摘要

磷酸葡萄糖变位酶（PGM）（5.4.2.2.）属于磷酸己糖变位酶超家族，在催化葡糖-1-磷酸（Glc-1-P）和葡糖-6-磷酸（Glc-6-P）的相互转化方面具有高度特异性。在本研究中，我们对观赏羽衣甘蓝花发育过程中两个胞质PGM（cPGM2和cPGM3）在柱头中的表达和活性进行了表征。在柱头中，cPGM的表达和活性在柱头发育过程中逐渐增加，在开花期前后活性最高。使用一种已知抑制剂阻断柱头中的cPGM活性，导致未成熟的S3和S4柱头的自交不亲和性被打破，但对完全成熟的S5柱头没有影响。很可能cPGM是成熟柱头中SI反应所需因子积累所必需的。
