Embryological studies on Fragaria x ananassa Duch. after pollination by three species of Potentilla
Embryological studies were carried out after pollinating four female varieties of Fragaria ananassa Duch. (Freja, Sonja, Mieze Schindler, Reine des Precoce) with three species of Poteiatilla (P. geoides, P. rupestris, P. fruticosa).

Identification of a molecular marker linked to apomixis in Brachiaria humidicola (Poaceae) [PDF]
A bulked segregant analysis using RAPD technique was carried out to identify molecular markers linked to apomixis in a Brachiaria humidicola F1 population that segregated 1 : 1 for the mode of reproduction (apomixis and sexual).

On the cytology of apogamy and apospory.—II. Preliminary note on apospory [PDF]
Apospory is the direct vegetative process which leads from the sporophyte to the gametophyte without the intervention of spores. This phenomenon has for a long time been known to occur in mosses and ferns, and several writers have described its morphological characters, but its cytological history has hitherto remained unrecorded.

In Silico and Fluorescence In Situ Hybridization Mapping Reveals Collinearity between the Pennisetum squamulatum Apomixis Carrier-Chromosome and Chromosome 2 of Sorghum and Foxtail Millet. [PDF]
Apomixis, or clonal propagation through seed, is a trait identified within multiple species of the grass family (Poaceae). The genetic locus controlling apomixis in Pennisetum squamulatum (syn Cenchrus squamulatus) and Cenchrus ciliaris (syn Pennisetum ...

Reproductive behavior in maize-Tripsacum polyhaploid plants : implications for the transfer of apomixis into maize [PDF]
L'expression de l'apomixie gamétophytique chez les graminées est limitée aux formes polyploïdes. Au cours de notre programme de transfert de l'apomixie de #Tripsacum$ tétraploïdes diplosporiques (2n = 4x = 72) au maïs (2n = 20) par rétrocroisements ...

Apomixis is a clonal mode of reproduction via seeds, which results from the failure of meiosis and fertilization in the sexual female reproductive pathway. In previous transcriptomic surveys, we identified a mitogen-activated protein kinase kinase kinase
