Depletion of Key Meiotic Genes and Transcriptome-Wide Abiotic Stress Reprogramming Mark Early Preparatory Events Ahead of Apomeiotic Transition

open access: yesFrontiers in Plant Science, 2016
Molecular dissection of apomixis - an asexual reproductive mode - is anticipated to solve the enigma of loss of meiotic sex, and to help fixing elite agronomic traits.

An epiQTL underlying asexual seed formation in Arabidopsis. [PDF]

open access: yesPlant Reprod
The DNA methylation status at an epigenetic quantitative trait locus in the Arabidopsis chromosome 2 is linked to the formation of apomictic-like endosperms.

TRIMETHYLGUANOSINE SYNTHASE1 mutations decanalize female germline development in Arabidopsis

open access: yesNew Phytologist, Volume 240, Issue 2, Page 597-612, October 2023., 2023
Summary Here, we report the characterization of a plant RNA methyltransferase, orthologous to yeast trimethylguanosine synthase1 (Tgs1p) and whose downregulation was associated with apomixis in Paspalum grasses. Using phylogenetic analyses and yeast complementation, we determined that land plant genomes all encode a conserved, specific TGS1 protein ...

The spread of infectious asexuality through haploid pollen

open access: yesNew Phytologist, Volume 230, Issue 2, Page 804-820, April 2021., 2021
Summary The mechanisms of initiation and transmission of apomixis (asexual reproduction through seeds) in natural plant populations are important for understanding the evolution of reproductive variation. Here, we used the phylogenetic diversity of the genus Boechera (Brassicaceae), together with natural diversity in pollen types produced by apomictic ...

Skipping sex: A nonrecombinant genomic assemblage of complementary reproductive modules

open access: yesBioEssays, Volume 43, Issue 1, January 2021., 2021
Asexuality arises through developmental alterations with apparently unrelated origins. We show the occurrence of asexual animals and plants have a common genetic and developmental basis on a single nonrecombinant assemblage of genomic elements altering complementary reproductive modules.

Research Advances in Multiple Embryos and Apomixis in Rice (<i>Oryza sativa</i> L.). [PDF]

open access: yesInt J Mol Sci
A typical seed of rice (Oryza sativa L.) gives rise to a single seedling. In contrast, seeds from multiple embryos may develop into two or more seedlings, one of which is generated via sexual reproduction, while the others are likely to originate through

Differentially methylated genes involved in reproduction and ploidy levels in recent diploidized and tetraploidized Eragrostis curvula genotypes. [PDF]

open access: yesPlant Reprod, 2023
Epigenetics studies changes in gene activity without changes in the DNA sequence. Methylation is an epigenetic mechanism important in many pathways, such as biotic and abiotic stresses, cell division, and reproduction.

Synthetic apomixis: the beginning of a new era.

open access: yesCurrent Opinion in Biotechnology, 2023
Apomixis is a process of asexual reproduction that enables plants to bypass meiosis and fertilization to generate clonal seeds that are identical to the maternal genotype. Apomixis has tremendous potential for breeding plants with desired characteristics,

Ovule Transcriptome Analysis Discloses Deregulation of Genes and Pathways in Sexual and Apomictic Limonium Species (Plumbaginaceae). [PDF]

open access: yesGenes (Basel), 2023
The genus Limonium Mill. (sea lavenders) includes species with sexual and apomixis reproductive strategies, although the genes involved in these processes are unknown.
