Observations of the Fine Structural Changes Associated with Merogony and Gametogony in Eimeria necatrix and Localization of Two Gametocyte Proteins [PDF]

Microorganisms
Coccidian parasites possess complex life cycles involving asexual proliferation followed by sexual development, producing oocysts that are transmitted from host to host through feces, guaranteeing disease transmission.

The rice eukaryotic translation initiation factor 3 subunit f (OseIF3f) is involved in microgametogenesis [PDF]

Frontiers in Plant Science, 2016
Microgametogenesis is the postmeiotic pollen developmental phase when unicellular microspores develop into mature tricellular pollen. In rice, microgametogenesis can influence grain yields to a great degree because pollen abortion occurs more easily ...

Comparative transcriptome analysis reveals key insights into male sterility in Salvia miltiorrhiza Bunge [PDF]

PeerJ, 2021
Background Large-scale heterosis breeding depends upon stable, inherited male sterility lines. We accidentally discovered a male sterility line (SW-S) in the F1progeny of a Salvia miltiorrhiza Bunge from Shandong, China (purple flowers) crossed with a S.

A multistage Plasmodium CRL4WIG1 ubiquitin ligase is critical for the formation of functional microtubule organization centers in microgametocytes [PDF]

mBio
Malaria is a mosquito-borne infectious disease caused by unicellular eukaryotic parasites of the Plasmodium genus. Protein ubiquitination by E3 ligases is a critical post-translational modification required for various cellular processes during the ...

Methodologies and Considerations in Evaluating Heat Stress Response and Thermotolerance of Pollen Grains. [PDF]

Physiol Plant
ABSTRACT Elevated temperatures severely disrupt pollen function, posing a major threat to agricultural productivity. While research into pollen thermotolerance is rapidly expanding, the quest to identify and develop heat‐tolerant crops is challenged by a lack of consistent methodological considerations and experimental design principles.

Whole-genomic DNA amplifications from individually isolated sweet sorghum microspores. [PDF]

Appl Plant Sci, 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

The effects of heat stress on male reproduction and tillering in Sorghum bicolor

Food and Energy Security, Volume 12, Issue 6, November 2023., 2023
Abstract Due to global climate change, heat stress is increasingly harming the growth, development, overall biomass, and grain yield of numerous crops. Heat stress impairs pollen development and thus reduces seed set in Sorghum bicolor (L.) Moench; however, the effects of heat stress on anther development at specific stages and tiller formation remain ...

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 ...

The tapetal tissue is essential for the maintenance of redox homeostasis during microgametogenesis in tomato

The Plant Journal, Volume 112, Issue 5, Page 1281-1297, December 2022., 2022
Significance Statement During anther development, the tapetal cells that surround the sporocytes have essential roles in male meiotic progression and the formation of mature pollen grains. In tomato, despite its importance for breeding purposes, the interaction between the tapetum and sporogenous tissues is poorly understood.

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,
