Proline synthesis in developing microspores is required for pollen development and fertility [PDF]
BMC Plant Biology, 2018 Background: In many plants, the amino acid proline is strongly accumulated in pollen and disruption of proline synthesis caused abortion of microspore development in Arabidopsis.

The GAMYB-like gene SlMYB33 mediates flowering and pollen development in tomato. [PDF]
Hortic Res, 2020 GAMYBs are positive GA signaling factors that exhibit essential functions in reproductive development, particularly in anther and pollen development. However, there is no direct evidence of the regulation of any GAMYB in these biological processes in ...

Transcript Profiling Analysis and ncRNAs’ Identification of Male-Sterile Systems of Brassica campestris Reveal New Insights Into the Mechanism Underlying Anther and Pollen Development [PDF]
Frontiers in Plant Science, 2022 Male-sterile mutants are useful materials to study the anther and pollen development. Here, whole transcriptome sequencing was performed for inflorescences in three sterile lines of Chinese cabbage (Brassica campestris L. ssp. chinensis Makino, syn.

Frontiers in Plant Science, 2017 Male sterility is important for hybrid seed production. Pollen development is regulated by a complex network. We previously showed that knockout of bHLH142 in rice (Oryza sativa) causes pollen sterility by interrupting tapetal programmed cell death (PCD)

Sequential Deposition and Remodeling of Cell Wall Polymers During Tomato Pollen Development [PDF]
Frontiers in Plant Science, 2021 The cell wall of a mature pollen grain is a highly specialized, multilayered structure. The outer, sporopollenin-based exine provides protection and support to the pollen grain, while the inner intine, composed primarily of cellulose, is important for ...

Mitochondrial Dynamics for Pollen Development
Plant Physiology, 2019 Mitochondria are active organelles that move rapidly, change shape, and undergo repeated fusion and fission ([Frederick and Shaw, 2007][1]; [Tilokani et al., 2018][2]). Since mitochondria have many important roles, including respiratory energy production

Rice GA3ox1 modulates pollen starch granule accumulation and pollen wall development.
PLoS ONE, 2023 The rice GA biosynthetic gene OsGA3ox1 has been proposed to regulate pollen development through the gametophytic manner, but cellular characterization of its mutant pollen is lacking.

Overexpression of SlOFP20 affects floral organ and pollen development. [PDF]
Hortic Res, 2019 The OVATE gene was initially identified in tomato and serves as a key regulator of fruit shape. There are 31 OFP members in the tomato genome. However, their roles in tomato growth and reproductive development are largely unknown. Here, we cloned the OFP

Biphasic regulation of the transcription factor ABORTED MICROSPORES (AMS) is essential for tapetum and pollen development in Arabidopsis [PDF]
New Phytologist, 2016 Viable pollen is essential for plant reproduction and crop yield. Its production requires coordinated expression at specific stages during anther development, involving early meiosis-associated events and late pollen wall formation.
