Effect of climate, anther morphology and pollination syndrome on pollen availability in Penstemon

open access: yesJournal of Pollination Ecology, 2023
Traditionally, pollen presentation is thought to be a function of pollinator type and visitation frequency. However, despite the repeated observation that pollen presentation is influenced by flower morphology and abiotic factors, these aspects have been

Tapetal 3-Ketoacyl-Coenzyme A Synthases Are Involved in Pollen Coat Lipid Accumulation for Pollen-Stigma Interaction in Arabidopsis

open access: yesFrontiers in Plant Science, 2021
Pollen coat lipids form an outer barrier to protect pollen itself and play essential roles in pollen-stigma interaction. However, the precise molecular mechanisms underlying the production, deposition, regulation, and function of pollen coat lipids ...

miR167 limits anther growth to potentiate anther dehiscence [PDF]

open access: yesDevelopment, 2019
ABSTRACT In flowering plants, anther dehiscence and pollen release are essential for sexual reproduction. Anthers dehisce after cell wall degradation weakens stomium cell junctions in each anther locule, and desiccation creates mechanical forces that open the locules. Either effect or both together may break stomium cell junctions.

Integrated Isoform Sequencing and Dynamic Transcriptome Analysis Reveals Diverse Transcripts Responsible for Low Temperature Stress at Anther Meiosis Stage in Rice

open access: yesFrontiers in Plant Science, 2021
Low temperatures stress is one of the important factors limiting rice yield, especially during rice anther development, and can cause pollen sterility and decrease grain yield.

Heat stress affects tassel development and reduces the kernel number of summer maize

open access: yesFrontiers in Plant Science, 2023
Maize grain yield is drastically reduced by heat stress (HTS) during anthesis and early grain filling. However, the mechanism of HTS in reproductive organs and kernel numbers remains poorly understood.

ZmMs33 promotes anther elongation via modulating cell elongation regulators, metabolic homeostasis, and cell wall remodeling in maize

open access: yesCrop Journal, 2023
Plant cell elongation depends on well-defined gene regulations, adequate nutrients, and timely cell wall modifications. Anther size is positively correlated with the number and viability of pollen grains, while little is known about molecular mechanisms ...

A Fragment Substitution in Promoter of MS92/PTC1 Causes Male Sterility in Rice

open access: yesRice Science, 2020
Persistent tapetal cell1 (PTC1) plays a curial role in pollen development, and is thought to function as a transcriptional activator in rice. However, the molecular mechanism of PTC1 in regulating pollen development and its cis-elements are not well ...
