Proteins, pollen tube growth and guidance
Pollination is a vital step for successful fertilization and seed formation in the angiosperms. Chae and Lord outline the crucial roles of small, secreted proteins in angiosperm pollination and fertilization by highlighting recent new findings on the roles of Arabidopsis thaliana lipid transfer proteins (LTPs) and a plantacyanin in pollen-tube tip growth and chemotropic guidance, [...]
