Comprehensive Insight into Tapetum-Mediated Pollen Development in Arabidopsis thaliana [PDF]
Cells, 2023 In flowering plants, pollen development is a key process that is essential for sexual reproduction and seed set. Molecular and genetic studies indicate that pollen development is coordinatedly regulated by both gametophytic and sporophytic factors ...

PXL1 and SERKs act as receptor-coreceptor complexes for the CLE19 peptide to regulate pollen development. [PDF]
Nat Commun, 2023 Gametophyte development in angiosperms occurs within diploid sporophytic structures and requires coordinated development; e.g., development of the male gametophyte pollen depends on the surrounding sporophytic tissue, the tapetum.

Functions of Redox Signaling in Pollen Development and Stress Response. [PDF]
Antioxidants (Basel), 2022 Cellular redox homeostasis is crucial for normal plant growth and development. Each developmental stage of plants has a specific redox mode and is maintained by various environmental cues, oxidants, and antioxidants.

MYB2 Is Important for Tapetal PCD and Pollen Development by Directly Activating Protease Expression in Arabidopsis. [PDF]
Int J Mol Sci, 2022 Tapetal programmed cell death (PCD) is a complex biological process that plays an important role in pollen formation and reproduction. Here, we identified the MYB2 transcription factor expressed in the tapetum from stage 5 to stage 11 that was essential ...
