Skipping sex: A nonrecombinant genomic assemblage of complementary reproductive modules
BioEssays, 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.

Harnessing wild relatives of pearl millet for germplasm enhancement: Challenges and opportunities
Crop Science, Volume 61, Issue 1, Page 177-200, January/February 2021., 2021 Abstract Pearl millet [Pennisetum glaucum (L.) R. Br.] is one of the world's hardiest warm‐season cereal crop and is cultivated mainly in the semi‐arid tropics of Asia and Africa for food, feed, fodder, and brewing. It is mainly cultivated for its gluten‐free grains with high content and better quality of nutrients.

Evolution of the apomixis transmitting chromosome in
BMC Evolutionary Biology, 2011 Background Apomixis is an intriguing trait in plants that results in maternal clones through seed reproduction. Apomixis is an elusive, but potentially revolutionary, trait for plant breeding and hybrid seed production.

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]
, 2017 Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

Chromosomal Evolution and Apomixis in the Cruciferous Tribe Boechereae
Frontiers in Plant Science, 2020 The mustard family (Brassicaceae) comprises several dozen monophyletic clades usually ranked as tribes. The tribe Boechereae plays a prominent role in plant research due to the incidence of apomixis and its close relationship to Arabidopsis.

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 ...

Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...

A unique life cycle transition in the red seaweed Pyropia yezoensis depends on apospory
Communications Biology, 2019 Plant life cycles consist of two temporally separated stages: a haploid gametophyte and a diploid sporophyte. In plants employing a haploid–diploid sexual life cycle, the transition from sporophyte to gametophyte generally depends on meiosis.
