Abstract
Iso-electric focusing of extracts derived from stigmatic homogenates of Brassica oleracea reveals that the mature stigma possesses large quantities of a glycoprotein not present in earlier stages of development in the bud. Pollen germination experiments carried out in parallel with the biochemical tests suggest that the appearance of this glycoprotein, which has an isoelectric point of pH 5.8, is coincident with the development of the self-incompatibility response. The site of this protein, and the role it may play in pollen-stigma interactions are discussed in terms of current models of the self-incompatibility system in Brassica.This publication has 16 references indexed in Scilit:
