Abstract: We aimed to unravel the underlying mechanisms of pollen wall development in Hydrangea bretschneiderii . For this, we tested our hypothesis that distinct physical processes, phase separation and micellar self-assembly, underpinned exine development by taking… read more here.

Abstract: In angiosperms, mature pollen is wrapped by a pollen wall, which is important for maintaining pollen structure and function. Pollen walls provide protection from various environmental stresses and preserve pollen germination and pollen tube growth.… read more here.

DOI: 10.1073/pnas.2201446119
Abstract: The surface of pollen grains is reinforced by pollen wall components produced non-cell autonomously by tapetum cells that surround developing pollen within the male floral organ, the anther. Here we show that tapetum activity is… read more here.

DOI: 10.1093/plphys/kiac307
Abstract: The pollen wall is important for protecting the male gametophyte and for fertilization. The lipid components of the pollen wall are mainly synthesized and transported from the sporophytic tapetum. Although several factors related to lipid… read more here.

Abstract: BackgroundDuring pollen wall formation in flowering plants, a conserved metabolon consisting of acyl-CoA synthetase (ACOS), polyketide synthase (PKS) and tetraketide α-pyrone reductase (TKPR), is required for sporopollenin synthesis. Despite this, the precise function of each… read more here.

DOI: 10.3390/ijms231911683
Abstract: The pollen wall is a specialized extracellular cell wall that protects male gametophytes from various environmental stresses and facilitates pollination. Here, we reported that bHLH010 and bHLH089 together are required for the development of the… read more here.
