Is the frequency of apomeiosis in the Rhodophyta a genetic character?
Hydrobiologia, 1987The small rhodophyte Antithamnionella sarniensis Lyle (Ceramiaceae), a very common species on the Atlantic coast of France, has a normal Polysiphonia-like life cycle (Sundene, 1964), but some tetraspores can give new tetrasporophytes directly (L’Hardy-Halos, 1985). This phenomenon has now been studied in detail (Magne, 1986).

Apomixis in daisy fleabanes (Erigeron annuus and E. strigosus) is controlled by two genetically unlinked loci that regulate, independently, the formation of unreduced female gametophytes (apomeiosis, diplospory) and autonomous seed formation (parthenogenesis).

Numerous candidate genes related to apomixis have been identified through transcriptomics; however, the molecular mechanism underlying apomixis remains unclear. Elucidation of the underlying mechanisms is essential to expand its application in crop breeding.

An Hieracium mutant, loss of apomeiosis 1 (loa1) is defective in the initiation of apomixis
Sexual Plant Reproduction, 2007Asexual seed formation (apomixis) in Hieracium aurantiacum occurs by mitotic embryo sac formation without prior meiosis in ovules (apomeiosis), followed by fertilization-independent embryo and endosperm development. Sexual reproduction begins first in Hieracium ovules with megaspore mother cell (MMC) formation.

Can We Use Gene-Editing to Induce Apomixis in Sexual Plants?
Genes, 2020 Apomixis, the asexual formation of seeds, is a potentially valuable agricultural trait. Inducing apomixis in sexual crop plants would, for example, allow breeders to fix heterosis in hybrid seeds and rapidly generate doubled haploid crop lines. Molecular

Revisiting apomixis via upstream epigenetic switches and downstream genetic effectors
The Plant JournalApomixis, the asexual formation of seeds, holds revolutionary potential for fixing hybrid vigor in crops. For decades, research in this field has been dominated by a gene‐centric view that focuses on identifying key regulators of apomeiosis and ...

A review on apomeiosis in Poa pratensis and Medicago sativa mutants.
2007In contrast to sexual reproduction, apomixis bypasses meiosis and egg cell fertilization. Gametophytic apomixis occurs with the parthenogenetic development of unreduced egg cells from apomeiotic embryo sacs originating from a nucellar somatic cell (apospory) or a megaspore mother cell with no, or modified, meiosis (diplospory).
