biologists, that apomicts meet the first criterion for being victorious
Five accessions (PI 295657, PI 315679, PI 409367, PI 409407, and PI 409704) were obligate apomicts or highly apomictic, whereas S 12103 was sexual.
Cytologically, all tetraploids were facultative apomicts.
Precocious gametophytization occurs in other apomicts (Asker and Jerling, 1992; Leblanc and Savidan, 1994; Peel et al.
However, apomicts, with few exceptions, generally occur in genera with low chromosome base numbers (average of 9.
1994; Valle and Savidan, 1996): tetraploid apomicts are simplex for a dominant allele (Aaaa) at the putative "apomixis locus," sexuals being homozygous recessive at the locus and either diploid (aa) or tetraploid (aaaa).
In many plants, seeds regularly develop from unfertilized egg cells or from cells other than egg cells; the resultant plants, termed apomicts, are genetically identical with the mother plant.
Dennis says several pasture grasses, such as Pennisetum and the maize relative Tripsicum, arc facultative apomicts.
Environmental sensitivity of sexual and apomictic Antennaria: Do apomicts have general-purpose genotypes?
annuus is similar to that of other prominent apomicts in the family Asteraceae, such as Taraxacum and Antennaria (McDonald, 1927; Mogie, 1992; Asker and Jerling, 1992).
decumbens hybrids, which were expected to segregate for edaphic adaptation because of the typically high heterozygosity level of apomicts such as B.
It appears that apomicts have larger ecological tolerances than their sexual progenitors probably because of (1) a hybrid and polyploid nature, combining or even exceeding the progenitors' ecological ranges and (2) the (near) absence of recombination such that a genotype doing well in a certain environment can produce equally well-adapted progeny (Bierzychudek 1989).
The species of the genus Citrus are facultative or obligate apomicts.
1989), and only Bierzychudek (1989), in her study of apomictic and sexual forms of Antennaria, showed convincingly that apomicts were less sensitive to changes in environmental conditions (i.
