The chromosome segment related to apomixis in Paspalum simplex is homeologous to the telomeric region of the long arm of rice chromosome 12
(Springer, 2001-12)
Apomixis is a form of asexual reproduction that in plants leads to the production of seed progeny that are exact copies of the mother individual. A mapping population generated by backcrossing a sexual with an apomictic ...
La apomixis, su estudio y posibles usos
(Universidad Nacional del Sur, 2008-06)
La apomixis es una forma de reproducción asexual a través de semillas que origina plantas genéticamente idénticas a la planta madre (clones). Su estudio para entender el funcionamiento, herencia y regulación a nivel génico ...
Sporophytic apomixis in polyploid Anemopaegma species (Bignoniaceae) from central Brazil
(2013-09-01)
Apomixis and polyploidy have been important in the evolution of the angiosperms, and sporophytic apomixis has been associated with polyembryony and polyploidy in tropical floras. We studied the occurrence of polyembryony ...

A Portion of the Apomixis Locus of Paspalum Simplex is Microsyntenic with an Unstable Chromosome Segment Highly Conserved Among Poaceae
(Nature Publishing Group, 2019-12)
The introgression of apomixis in major seed crops, would guarantee self-seeding of superior heterotic seeds over generations. In the grass species Paspalum simplex, apomixis is controlled by a single locus in which ...
Analysis of the methylation status of the apomixis-specific region in Paspalum spp. suggests an epigenetic control on parthenogenesis
(Oxford University Press, 2014-12)
Apomixis, a clonal plant reproduction by seeds, is controlled in Paspalum spp. by a single locus which is blocked in terms of recombination. Partial sequence analysis of the apomixis locus revealed structural features of ...
