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

open access: yesThe Plant Journal, Volume 112, Issue 5, Page 1281-1297, December 2022., 2022
SUMMARY The tapetum is a specialized layer of cells within the anther, adjacent to the sporogenous tissue. During its short life, it provides nutrients, molecules and materials to the pollen mother cells and microsporocytes, being essential during ...

Identity Transitions of Tapetum Phases: Insights into Vesicular Dynamics and in Mortem Support During Pollen Maturation [PDF]

open access: yesPlants
Flower development progresses through twelve distinct stages, meticulously regulated to optimize plant reproductive success. At stage 5, the initiation of anther development occurs, which is further categorized into 14 stages divided into two defined ...

Plastid differentiation during microgametogenesis determines green plant regeneration in barley microspore culture.

open access: yesPlant Science, 2020
Developing plants from in vitro culture of microspores or immature pollen grains (androgenesis) is a highly genotype-dependent process whose effectiveness in cereals is significantly reduced by occurrence of albino regenerants. Here, we examined a hypothesis that the molecular differentiation of plastids in barley microspores prior to in vitro culture ...

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

open access: yesFrontiers 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 ...

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

open access: yesMicroorganisms
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.

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

open access: yesPeerJ, 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.

Quantitative assessment of DNA replication to monitor microgametogenesis in Plasmodium berghei

open access: yesMolecular and Biochemical Parasitology, 2009
Targeting the crucial step of Plasmodium transition from vertebrate host to mosquito vector is a promising approach to eliminate malaria. Uptake by the mosquito activates gametocytes within seconds, and in the case of male (micro) gametocytes leads to rapid DNA replication and the release of eight flagellated gametes.

Microsporogenesis, microgametogenesis and pollen morphology of Passiflora spp. (Passifloraceae) [PDF]

open access: yesBotanical Journal of the Linnean Society, 2002
Microsporogenesis, microgametogenesis and pollen morphology of six species of genus Passiflora L. belonging to three subgenera (Passiflora, Dysosmia, Decaloba) were studied with light and scanning microscopy; P. caerulea was also examined with transmission microscopy.

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

open access: yesmBio
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 ...

Identification of microspore-active promoters that allow targeted manipulation of gene expression at early stages of microgametogenesis in Arabidopsis

open access: yesBMC Plant Biology, 2006
Background The effective functional analysis of male gametophyte development requires new tools enabling the spatially and temporally controlled expression of both marker genes and modified genes of interest.
