Effects of sucrose depletion on pollen tube growth
BcMF8 contributes to pollen wall development and tube growth
Lin et al. examine expression of Brassica campestris male fertility 8 (BcMF8) in pistils of Chinese cabbage (B. campestris ssp. chinensis), and find that it encodes a putative AGP that is located in the cell wall and is expressed in pollen grains and pollen tubes.

August Image: Apple Stigma
This month the inset cover image shows a detail of the stigma of a flower of apple, Malus × domestica. The acquisition of stigmatic receptivity is concomitant with secretion of arabinogalactan proteins (AGPs, strained green) into the intercellular spaces between cell walls (blue).
