Definition of apomixis in English:

apomixis

noun

Botany
  • [mass noun] Asexual reproduction in plants, in particular agamospermy.

    Often contrasted with amphimixis
    • ‘Some angiosperms reproduce by apomixis, a natural way of cloning through seeds.’
    • ‘During in vivo development, maternal apomixis refers to the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization.’
    • ‘To eliminate the possibility of apomixes an additional treatment was added in 2000: flowers on 10 female plants were bagged.’
    • ‘A second explanation for the formation of seed in bagged hermaphroditic flowers can be apomixis, the formation of seed without pollination.’
    • ‘Polyembryonic seeds can arise through several developmental pathways and in some cases may involve apomixis stimulated by fertilization of nearby ovules.’
    • ‘Plants also show great ranges in self-fertility from obligate outcrossing to complete selfing to apomixis (uniparental).’
    • ‘Pollen quality may be correlated with male fertility and apomixis.’
    • ‘It is noteworthy that according to the studies of Illg, M. brasiliensis may be apomictic, although pollinator-dependent; i.e. apomixis is triggered by pollen-tube development.’
    • ‘Five individuals were assigned to a fifth treatment to investigate the possibility of apomixis.’
    • ‘No experiments were conducted to test whether or not the high fruit set observed in this species was due to apomixis.’
    • ‘Only one plant in the apomixis treatment developed two ovules.’
    • ‘Another example is the major impact that understanding apomixis would have on plant breeding.’
    • ‘The particular form of apomixis involves the development of a 2n embryo sac followed by fertilization of the central nuclei to form the endosperm (pseudogamy).’
    • ‘There are two types of thelytokous reproduction: apomixis - clonal reproduction, which can be diploid or polyploid - and automixis, a meiosis that takes place after which diploidy is restored.’
    • ‘Therefore it can be assumed that the seeds analyzed in this study were the result of neither selfing nor apomixis.’
    • ‘Most published work on poaceae is devoted to plant breeding issues, since apomixis - which allows hybrids to breed true - is as valuable a trait in plant breeding as in population biology.’
    • ‘The asexuality may be of any kind including apomixis (reproduction by unreduced egg cells).’
    • ‘The values given in Table 3 are only indicative of the success of the crosses and should not be considered as definitive, since selfing, and probably also apomixis, took place in some of the cases.’
    • ‘Genetic and molecular mapping studies based on the analysis of offspring from apomictic by sexual crosses have been carried out on multiple species reproducing by gametophytic apomixis.’
    • ‘In apomixis, an embryo is created from a diploid cell in the ovule.’
