The recombination and copy number shifting activities of the plant mitochondrial genome are widely documented across plant genera, but these genome processes have not been as well examined with regard to their roles in plant evolution. Because of the extensive plant collections of Phaseolus spp a...

Isozyme variation was studied in 87 plants from 32 cultivated and wild accessions of banana passion fruit (P. tripartita var. mollissima, P. tripartita var. tripartita, P. tarminiana, and P. mixta), rosy passion fruit (P. cumbalensis), tin-tin (P. pinnatistipula), gulián (P. ampullacea), P. antio...

Relationships between cultivated and wild species]Isozyme variation in Passiflora subgenera Tacsonia and Manicata. Relationships between cultivated and wild species

Cassava cultivars often have poor resistance to biotic stresses and lack good quality traits. Wild species of cultivated crops have frequently been used as an important source of genetic diversity. Cassava breeders are becoming increasingly interested in incorporating genes of wild relatives. In ...

The extent of 5S and 45S ribosomal DNA (rDNA) variation was investigated in wild and domesticated common beans (Phaseolus vulgaris) chosen to represent the known genetic diversity of the species. 5S and 45S rDNA probes were localized on mitotic chromosomes of 37 accessions by fluorescent in situ ...

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant species, are sources of valuable genetic resources for crop improvement. Persisting gaps in knowledge of taxonomy, distributions, and characterization for traits of interest constrain their expanded use in p...

This paper summarizes results from a decade of collaborative research using advanced backcross (AB) populations to a) identify quantitative trait loci (QTL) associated with improved performance in rice and to b) clone genes underlying key QTLs of interest. We demonstrate that AB-QTL analysis is c...

Se presenta una revisión de la distribución geográfica de las formas silvestres del fríjol común y del fríjol lima en el Neotrópico, de sus características morfológicas y ecológicas, y de la variación bioquímica y molecular a lo largo de esta distribución. Estos hechos muestran que la diversidad ...
