The SlHB8 acts as a negative regulator in tapetum development and pollen wall formation in Tomato. [PDF]
Hortic Res, 2022 Pollen development is crucial for the fruit setting process of tomatoes, but the underlying regulatory mechanism remains to be elucidated. Here, we report the isolation of one HD-Zip III family transcription factor, SlHB8, whose expression levels ...

POLLEN WALL ABORTION 1 is essential for pollen wall development in rice
Plant Physiology, 2022 Abstract The integrity of pollen wall structures is essential for pollen development and maturity in rice (Oryza sativa L.). In this study, we isolated and characterized the rice male-sterile mutant pollen wall abortion 1 (pwa1), which exhibits a defective pollen wall (DPW) structure and has sterile pollen.

AN OVERVIEW OF POLLEN AND ANTHER WALL DEVELOPMENT IN Catalpa bignonioides Walter (BIGNONIACEAE)
Trakya University Journal of Natural Sciences, 2017 Anther development in Catalpa bignonioides Walter was investigated from the sporogenous cell to the mature pollen grain stages to determine whether the pollen and anther wall development follows the basic scheme in angiosperms.

Acta Societatis Botanicorum Poloniae, 2014 Autafluarescence of the pollen wall of Lilium shows a correlative change with its development. When the pollen of Gasteria is injected into the anther of Lilium, it exhibits almost the same characteristics of wall autofluorescence as those of Lilium ...

Defective Pollen Wall 3 (DPW3), a novel alpha integrin‐like protein, is required for pollen wall formation in rice [PDF]
New Phytologist, 2019 Summary In flowering plants, pollen wall is a specialized extracellular cell‐wall matrix surrounding male gametophytes and acts as a natural protector of pollen grains against various environmental and biological stresses. The formation of pollen wall is a complex but well‐regulated process, which involves the action of many different genes. However,

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation. [PDF]
Proc Natl Acad Sci U S A, 2022 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.

ADAPTOR PROTEIN-1 complex-mediated post-Golgi trafficking is critical for pollen wall development in Arabidopsis. [PDF]
New Phytol, 2022 Summary Primexine deposition is essential for the formation of pollen wall patterns and is precisely regulated by the tapetum and microspores. While tapetum‐ and/or microspore‐localized proteins are required for primexine biosynthesis, how their ...
