callose synthase 5
NCBI Summary
Responsible for the synthesis of callose deposited at the primary cell wall of meiocytes, tetrads and microspores. Required for exine formation during microgametogenesis and for pollen viability. Highest expression in meiocytes, tetrads, microspores and mature pollen.

UniProt Comments
Required for the formation of the callose wall separating the tetraspores (interstitial wall) and surrounding the pollen mother cells (pheripheral wall). Required for exine formation on pollen wall. May be involved in callose synthesis during pollen tube growth. During plant growth and development, callose is found as a transitory component of the cell plate in dividing cells, is a major component of pollen mother cell walls and pollen tubes, and is found as a structural component of plasmodesmatal canals.
