Successful crosses between fungal-resistant wild species of Arachis (section Arachis) and Arachis hypogaea
Peanut (Arachis hypogaea) is the fifth most produced oil crop worldwide. Besides lack of water, fungal diseases are the most limiting factors for the crop. Several species of Arachis are resistant to certain pests and diseases. This study aimed to successfully cross the A-genome with B-K-A genome wild species previously selected for fungal disease resistance, but that are still untested. We als...
متن کاملAbundant Microsatellite Diversity and Oil Content in Wild Arachis Species
The peanut (Arachis hypogaea) is an important oil crop. Breeding for high oil content is becoming increasingly important. Wild Arachis species have been reported to harbor genes for many valuable traits that may enable the improvement of cultivated Arachis hypogaea, such as resistance to pests and disease. However, only limited information is available on variation in oil content. In the presen...
متن کاملGenomic characterisation of Arachis porphyrocalyx (Valls & C.E. Simpson, 2005) (Leguminosae): multiple origin of Arachis species with x = 9
The genus Arachis Linnaeus, 1753 comprises four species with x = 9, three belong to the section Arachis: Arachis praecox (Krapov. W.C. Greg. & Valls, 1994), Arachis palustris (Krapov. W.C. Greg. & Valls, 1994) and Arachis decora (Krapov. W.C. Greg. & Valls, 1994) and only one belongs to the section Erectoides: Arachis porphyrocalyx (Valls & C.E. Simpson, 2005). Recently, the x = 9 species of se...
متن کاملComparative bioinformatics analysis of a wild diploid Gossypium with two cultivated allotetraploid species
Background: Gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. G. thurberi belongs to D genome, which is an important wild bio-source for the cotton breeding and genetic research. To a certain degree, chloroplast DNA sequence information are a versatile tool for species identification and phylogenetic implications in plants. Different ch...
متن کاملMeiotic Diploid Progeny and Meiotic Nondisjunction in SACCHAROMYCES CEREVISIAE.
Abnormalities in chromosome number that occurred during meiosis were evaluated with a specially-constructed diploid strain of Saccharomyces cerevisiae. The strain is heterozygous for six markers of the right arm of chromosome V and heterozygous for cyh2 (resistance to cycloheximide) on chromosome VII.-Selection of meiotic spores on a medium containing cycloheximide and required nutrilites-excep...
