A pollen-expressed gene from rice, OsPCBP, that was previously cloned and identified encodes a novel calmodulin-binding protein. Here, we investigated its functioning in pollen development. Overexpression of OsPCBP in transgenic rice plants did not lead to phenotypic changes but did delay anther formation by about 1 week. Cytological observations at(More)
The Wnt4 molecule is a secretory glycoprotein implicated in proliferation and differentiation of both normal and malignant cells. Despite extensive investigation of Wnt4 expression in various cancers, little is known about its expression pattern in different types of pituitary tumors. In this study, we examined the expression of Wnt4 and its downstream(More)
