Callose (beta-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth.

BMC plant biology - 7 Oct 2005

Abstract excerpt

BACKGROUND: Callose (beta-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that segment growing tubes. Mutations in CalS5, one of several Arabidopsis beta-1,3 glucan synthases, were previously shown to disrupt callose formation around...
