Partitioning Apomixis Components to Understand and Utilize Gametophytic Apomixis [PDF]

Frontiers in Plant Science, 2019
Apomixis is a method of reproduction to generate clonal seeds and offers tremendous potential to fix heterozygosity and hybrid vigor. The process of apomictic seed development is complex and comprises three distinct components, viz., apomeiosis (leading ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

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

BMC 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

Frontiers 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

Theoretical 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

Frontiers 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.

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

Plants, 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 ...

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

, 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 ...

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

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

Genetic mechanisms of apomixis [PDF]

Philosophical 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 ...
