A Full-Length Reference Floral Transcriptome of Boehmeria tricuspis Provides Insights into Apomeiosis and Polyploidy [PDF]
International Journal of Genomics, 2019 Boehmeria tricuspis (Hance) Makino constitutes a hardy herbaceous or shrubby perennial native to East Asia that includes different ploidy levels and reproductive modes (diplosporous to sexual).

Inheritance of apomeiosis (diplospory) in fleabanes (Erigeron, Asteraceae) [PDF]
Heredity, 2004 Unreduced egg formation (apomeiosis) in flowering plants is rare except when it is coupled with parthenogenesis to yield gametophytic apomixis via apospory or diplospory. Results from genetic mapping studies in diverse apomictic taxa suggest that apomeiosis and parthenogenesis are genetically linked, a finding that is compatible with the conventional ...

Asexual thalli originated from sporophytic thalli via apomeiosis in the green seaweed Ulva [PDF]
Scientific Reports, 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.

The
New Phytologist, 2013 Summary Apomixis or asexual seed formation in Hieracium praealtum (Asteraceae) is controlled by two independent dominant loci. One of these, the LOSS OF APOMEIOSIS (LOA) locus, controls apomixis initiation, mitotic embryo sac formation (apospory) and suppression of the sexual pathway.

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.

Apomictic and sexual germline development differ with respect to cell cycle, transcriptional, hormonal and epigenetic regulation. [PDF]
PLoS Genetics, 2014 Seeds of flowering plants can be formed sexually or asexually through apomixis. Apomixis occurs in about 400 species and is of great interest for agriculture as it produces clonal offspring. It differs from sexual reproduction in three major aspects: (1)

Methods in Molecular BiologyAbstract Heterosis, or hybrid vigor, is a crucial driver of yield and robustness in modern hybrid breeding. However, F1 hybrid plants give rise to genetically variable F2 offspring due to the segregation of genetic material in male and female meiosis.

Apomeiosis inAcinetospora (phaeophyceae, ectocarpales) [PDF]
Helgoländer Meeresuntersuchungen, 1986 Acinetospora crinita from the Mediterranean Sea has been studied in laboratory cultures. The plants formed monospores and unilocular sporangia. Both monospores and zoids from unilocular sporangia developed to new plants with the same habitus and chromosome number (average ca 47).

Phylogenetically Distant BABY BOOM Genes From Setaria italica Induce Parthenogenesis in Rice
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 ...
