Structure of staminate flowers, microsporogenesis, and microgametogenesis in Helosis cayennensis var. cayennensis (Balanophoraceae)

Anales del Jardín Botánico de Madrid, 2013
We analyzed the microgametogenesis and microsporogenesis of the male flowers of the holoparasitic Helosis cayennensis (Sw.) Spreng. var. cayennensis using optical and scanning electron microscopy.

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.

Microsporogenesis, microgametogenesis, and pollen grain morphology of Fouquieria fasciculata (Fouquieriaceae, Ericales)

Botan‪ical Sciences, 2023
Background: Embryology of the male reproductive structures in Fouquieriaceae has been poorly studied. The ontogeny of the anther wall, microsporogenesis, microgametogenesis, and pollen morphology were described in detail for Fouquieria fasciculata ...

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 ...

Microgametophyte Development in Cannabis sativa L. and First Androgenesis Induction Through Microspore Embryogenesis

Frontiers in Plant Science, 2021
Development of double haploids is an elusive current breeding objective in Cannabis sativa L. We have studied the whole process of anther and pollen grain formation during meiosis, microsporogenesis, and microgametogenesis and correlated the different ...

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 ...

Classification and Computational Analysis of Arabidopsis thaliana Sperm Cell-Specific F-Box Protein Gene 3p.AtFBP113

Frontiers in Genetics, 2020
In plants, F-box proteins (FBPs) constitute one of the largest superfamilies of regulatory proteins. Most F-box proteins are shown to be an integral part of SCF complexes, which carry out the degradation of proteins and regulate diverse important ...

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 ...
