Small RNA sequencing provides candidate miRNA-target pairs for revealing the mechanism of apomixis in Zanthoxylum bungeanum

open access: yesBMC Plant Biology, 2021
Background Apomixis is a form of asexual reproduction that produces offspring without the need for combining male and female gametes, and the offspring have the same genetic makeup as the mother.

Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera

open access: yesFrontiers in Plant Science, 2022
Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Engineering apomixis in crops

open access: yesTheoretical and Applied Genetics, 2023
AbstractApomixis is an asexual mode of reproduction through seeds where progeny are clones of the mother plants. Naturally apomictic modes of reproduction are found in hundreds of plant genera distributed across more than 30 plant families, but are absent in major crop plants.

Genomic methylation patterns in pre-meiotic gynoecia of wild-type and RdDM mutants of Arabidopsis

open access: yesFrontiers in Plant Science, 2023
IntroductionAlthough DNA methylation patterns are generally considered to be faithfully inherited in Arabidopsis thaliana (Arabidopsis), there is evidence of reprogramming during both male and female gametogenesis.

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

open access: yes, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Differential Epigenetic Marks Are Associated with Apospory Expressivity in Diploid Hybrids of Paspalum rufum

open access: yesPlants, 2021
Apomixis seems to emerge from the deregulation of preexisting genes involved in sexuality by genetic and/or epigenetic mechanisms. The trait is associated with polyploidy, but diploid individuals of Paspalum rufum can form aposporous embryo sacs and ...

Genetic mechanisms of apomixis [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
The introduction of apomixis to crops would allow desirable genotypes to be propagated while preventing undesirable gene flow, but so far there has been little success in transferring this trait from a natural apomict to another species. One explanation is the sensitivity of endosperm to changes in relative maternal and paternal contribution owing to ...

Immanent Anthropology: A Comparative Study of 'Process' in Contemporary France [PDF]

open access: yes, 2014
This paper presents a comparative critique of the ‘processual temporalities’ which infuse both social-scientific theorizing and selected Western cultural practices.

Viewpoints on apornictic and sexual reproduction in angiosperms

open access: yesActa Societatis Botanicorum Poloniae, 2014
Gametophytic apomixis implies different changes of the reproductive cycle of sexual plants. Each of these "elements of apomixis" occurs in sexual plants, which may even display functional diploid parthenogenesis.

Crop biotechnology: prospects and opportunities [PDF]

open access: yes, 2010
SUMMARYThis paper is a brief review summarizing some of the important areas of activity in crop biotechnology likely to be exploited over the medium term (10–20 years), with an emphasis on agronomic traits.
