متن کاملGeographical and environmental range expansion through polyploidy in wild potatoes ( Solanum section Petota )
Aim To assess evidence for geographical and environmental range expansion through polyploidy in wild potatoes ( Solanum sect. Petota ). There are diploids, triploids, tetraploids, pentaploids and hexaploids in this group. Location Wild potatoes occur from the south-western USA (Utah and Colorado), throughout the tropical highlands of Mexico, Central America and the Andes, to Argentina, Chile an...
متن کاملEx Situ Conservation Priorities for the Wild Relatives of Potato (Solanum L. Section Petota)
Crop wild relatives have a long history of use in potato breeding, particularly for pest and disease resistance, and are expected to be increasingly used in the search for tolerance to biotic and abiotic stresses. Their current and future use in crop improvement depends on their availability in ex situ germplasm collections. As these plants are impacted in the wild by habitat destruction and cl...
متن کاملNew taxa in Aspergillus section Usti
Based on phylogenetic analysis of sequence data, Aspergillus section Usti includes 21 species, inclucing two teleomorphic species Aspergillus heterothallicus (= Emericella heterothallica) and Fennellia monodii. Aspergillus germanicus sp. nov. was isolated from indoor air in Germany. This species has identical ITS sequences with A. insuetusCBS 119.27, but is clearly distinct from that species ba...
متن کاملEcogeography of ploidy variation in cultivated potato (Solanum sect. Petota).
UNLABELLED PREMISE OF THE STUDY The taxonomy of cultivated potatoes has been highly controversial, with estimates of species numbers ranging from 3 to 17. Ploidy level has been one of the most important taxonomic characters to recognize cultivated potato species, containing diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), and pentaploid (2n = 5x = 60) cultivars. We...
