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.

A review on apomeiosis in Poa pratensis and Medicago sativa mutants.
, 2007 In 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).

Research Advances in Multiple Embryos and Apomixis in Rice (Oryza sativa L.) [PDF]
Int J Mol SciA typical seed of rice (Oryza sativa L.) gives rise to a single seedling. In contrast, seeds from multiple embryos may develop into two or more seedlings, one of which is generated via sexual reproduction, while the others are likely to originate through

Recent Progress on Plant Apomixis for Genetic Improvement [PDF]
Int J Mol SciApomixis is a reproductive process that produces clonal seeds while bypassing meiosis (or apomeiosis) without undergoing fertilization (or pseudo-fertilization).

Gamete formation without meiosis in Arabidopsis
Nature, 2008 Apomixis, the formation of asexual seeds in plants, leads to populations that are genetically uniform maternal clones. The transfer of apomixis to crop plants holds great promise in plant breeding for fixation of heterozygosity and hybrid vigour because ...

Quantitative variation for apomictic reproduction in the genus Boechera (Brassicaceae).
American-Eurasian journal of botany, 2010 • Premise of the study: The evolution of asexual seed production (apomixis) from sexual relatives is a great enigma of plant biology. The genus Boechera is ideal for studying apomixis because of its close relation to Arabidopsis and the occurrence of ...
