Callose Deposition during Pollen Development

Abstract

Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new article investigating pollen formation in cotton (Gossypium hirsutum), we now know that a pollen-specific protein regulates callose deposition by inhibiting the action of a transcription factor, WRKY15 (Li et al., 2020).
