91) suggested that apogamy and apospory would probably be associated with changes in chromosome number.
One restriction fragment length polymorphism (RFLP) (UGT197) and one random amplified polymorphic DNA (RAPD) (OPC4) were syntenic with apospory in interspecific Pennisetum hybrids (Ozias-Akins et al.
Analyses of isozyme, protein, and RAPD markers did not identify associations with apospory in buffelgrass (Gustine et al.
1998) identified 12 sequence characterized amplified regions (SCARs) cosegregating with apospory in an interspecific population of P.
Apospory is the formation of a gametophyte by the sporophyte, without the function of actual melospores.
This is particularly true, as discussed, of such often hailed points (allegedly supporting the homologous theory) as apogamy/ apospory and the presence of limited chlorophyll in allegedly reduced hepatophyte sporophytes (such as those of Ricciocarpus).
Several clones of maize chromosome 5 (including UMC72 and UMC147) and rice chromosome 2 (including RZ273), have been found to belong to the linkage group that includes the factor(s) for apospory in Brachiaria hybrids (Pessino et al.
Regarding the location of markers that have been reported as linked to apomixis in related species, Paspalum Linkage Group 4 and 5, which included clones linked to apospory in Brachiaria (Pessino et al.
Thus, polysporic species may have in some cases evolved from diplospory or apospory, as well as monospory.
Ultrastructural characterization of apospory in Panicum maximum.
Additional RAPD markers are needed to prepare an initial map of loci linked to the apospory locus in buffelgrass.
The N15-370 marker was of interest in that the parents and the bulks (with one exception) fit the pattern of expression expected for a linked marker, and furthermore because its pattern of expression duplicated that of UGT197-144, which was linked to apospory (Ozias-Akins et al.
