RUVBL proteins are involved in plant gametophyte development

The Plant Journal, Volume 114, Issue 2, Page 325-337, April 2023., 2023
Significance Statement We show that RUVBL1 and RUVBL2, plant orthologues of human Pontin and Reptin, are essential for the proper development of both male and especially female gametophytes in Arabidopsis. SUMMARY The proper development of male and female gametophytes is critical for successful sexual reproduction and requires a carefully regulated ...

Hydroxyproline-O-Galactosyltransferases Synthesizing Type II Arabinogalactans Are Essential for Male Gametophytic Development in Arabidopsis

Frontiers in Plant Science, 2022
In flowering plants, male reproductive function is determined by successful development and performance of stamens, pollen grains, and pollen tubes. Despite the crucial role of highly glycosylated arabinogalactan-proteins (AGPs) in male gamete formation,

Strategies of tolerance reflected in two North American maple genomes

The Plant Journal, Volume 109, Issue 6, Page 1591-1613, March 2022., 2022
SUMMARY Maples (the genus Acer) represent important and beloved forest, urban, and ornamental trees distributed throughout the Northern hemisphere. They exist in a diverse array of native ranges and distributions, across spectrums of tolerance or decline, and have varying levels of susceptibility to biotic and abiotic stress.

NETWORKED2‐subfamily proteins regulate the cortical actin cytoskeleton of growing pollen tubes and polarised pollen tube growth

New Phytologist, Volume 231, Issue 1, Page 152-164, July 2021., 2021
Summary We have recently characterised NET2A as a pollen‐specific actin‐binding protein that binds F‐actin at the plasma membrane of growing pollen tubes. However, the role of NET2 proteins in pollen development and fertilisation have yet to be elucidated.

High Temperature Has Negative Impact on Pollen Development in Chili Pepper (Capsicum annuum L.) cv. Tanjung-2

Jurnal Ilmu Pertanian Indonesia, 2020
The development of male reproductive organ in plants is seriously affected by the adverse abiotic stresses. In this study, we investigated pollen development, particularly at microsporogenesis and micro gametogenesis stages of chili pepper (Capsicum ...

Dynamics of Calcium during In vitro Microspore Embryogenesis and In vivo Microspore Development in Brassica napus and Solanum melongena

Frontiers in Plant Science, 2017
Calcium is widely known to have a role as a signaling molecule in many different processes, including stress response and activation of the embryogenic program.

Differential Expression Profiling Reveals Stress-Induced Cell Fate Divergence in Soybean Microspores

Plants, 2020
Stress-induced microspore embryogenesis is a widely employed method to achieve homozygosity in plant breeding programs. However, the molecular mechanisms that govern gametophyte de- and redifferentiation are understood poorly.

Plasmodium APC3 mediates chromosome condensation and cytokinesis during atypical mitosis in male gametogenesis [PDF]

, 2018
The anaphase promoting complex/cyclosome (APC/C) is a highly conserved multi-subunit E3 ubiquitin ligase that controls mitotic division in eukaryotic cells by tagging cell cycle regulators for proteolysis.

Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]

, 2009
In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.

Microsporogenesis and microgametogenesis of the Argentinian species ofPodocarpus(Podocarpaceae) [PDF]

Botanical Journal of the Linnean Society, 1996
Abstract The development of the microsporangium and male gametophyte of three species of Podocarpus was studied with light microscopy (LM) and the morphology of pollen with scanning and transmission electron microscopy (SEM and TEM). During early stages, the male cone is covered with coriaceous scales.
