Asexual thalli originated from sporophytic thalli via apomeiosis in the green seaweed Ulva. [PDF]
Sci Rep, 2019 AbstractApomixis is an asexual reproduction system without fertilization, which is an important proliferation strategy for plants and algae. Here, we report on the apomeiosis in the green seaweed Ulva prolifera, which has sexual and obligate asexual populations.

To infinity and beyond: recent progress, bottlenecks, and potential of clonal seeds by apomixis. [PDF]
Plant JSUMMARY Apomixis – clonal seed production in plants – is a rare yet phylogenetically widespread trait that has recurrently evolved in plants to fix hybrid genotypes over generations. Apomixis is absent from major crop species and has been seen as a holy grail of plant breeding due to its potential to propagate hybrid vigor in perpetuity.

Turning meiosis into mitosis. [PDF]
PLoS Biology, 2009 Apomixis, or asexual clonal reproduction through seeds, is of immense interest due to its potential application in agriculture. One key element of apomixis is apomeiosis, a deregulation of meiosis that results in a mitotic-like division.

Genetic fine-mapping of
BMC Plant Biology, 2010 Background DIPLOSPOROUS (DIP) is the locus for diplospory in Taraxacum, associated to unreduced female gamete formation in apomicts. Apomicts reproduce clonally through seeds, including apomeiosis, parthenogenesis, and autonomous or pseudogamous ...

New Frontiers in Potato Breeding: Tinkering with Reproductive Genes and Apomixis [PDF]
BiomoleculesPotato is the most important non-cereal crop worldwide, and, yet, genetic gains in potato have been traditionally delayed by the crop’s biology, mostly the genetic heterozygosity of autotetraploid cultivars and the intricacies of the reproductive system.

Phylogenetically Distant BABY BOOM Genes From Setaria italica Induce Parthenogenesis in Rice [PDF]
Frontiers in Plant Science, 2022 The combination of apomixis and hybrid production is hailed as the holy grail of agriculture for the ability of apomixis to fix heterosis of F1 hybrids in succeeding generations, thereby eliminating the need for repeated crosses to produce F1 hybrids ...

Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals [PDF]
Frontiers in Plant Science, 2019 Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo ...
