Wilt, caused by Fusarium oxysporum f. sp. ricini, is the most severe disease of castor bean (Ricinus communis). For the development of marker for wilt-resistant gene, 200 F2 individuals from a cross between the resistant cultivar 48-1 and the susceptible cultivar VP-1 were inoculated with a race of Fusarium oxysporum f. sp. ricini. Bulked segregant analysis was used to search for random amplifi...

An F(1) mapping population of the septoria tritici blotch pathogen of wheat, Mycosphaerella graminicola, was generated by crossing the two Dutch field isolates IPO323 and IPO94269. AFLP and RAPD marker data sets were combined to produce a high-density genetic linkage map. The final map contained 223 AFLP and 57 RAPD markers, plus the biological traits mating type and avirulence, in 23 linkage g...

doi: 10.1111/j.1399-3054.2006.00739.x To investigate selenium tolerance mechanisms in Arabidopsis thaliana, genetic and physiologic studies were performed in the three Arabidopsis accessions Landsberg erecta (Ler), Columbia (Col) and Wassilewskija (Ws). Accession Ler was significantly less tolerant to selenate than Ws and Col, whereas Ws was less tolerant to selenite than the others. Analysis o...

Quantitative trait loci (QTL) mapping of forest productivity traits was performed using an open pollinated half-sib family of Eucalyptus grandis. For volume growth, a sequential QTL mapping approach was applied using bulk segregant analysis (BSA), selective genotyping (SG) and cosegregation analysis (CSA). Despite the low heritability of this trait and the heterogeneous genetic background emplo...

Cytoplasmic male-sterility (CMS) has been exclusively used to produce F1 hybrid seeds of onion (Allium cepa L.). A single nuclear locus, Ms, is known restore male-fertility CMS in onions. Unstable male-sterile onions producing a small amount pollen grains have identified previous study. When such unstable were crossed with stable containing CMS-R cytoplasm, was completely restored, although gen...

Soybean (Glycine max) has a paleopolyploid genome, and many re-sequencing experiments to characterize soybean genotypes have been conducted using next-generation sequencing platforms. The accumulation of information about single nucleotide polymorphisms (SNPs) throughout the soybean genome has accelerated identification of genomic regions related to agronomically important traits through associ...

A Fragaria Discovery Panel (FDP; strawberry-specific SDA) containing 287 features was constructed by subtracting the pooled gDNA of nine non-angiosperm species from the pooled gDNA of five strawberry genotypes. This FDP was used for Bulk Segregant Analysis (BSA) to enable identification of molecular markers associated with day-neutrality. Analysis of hybridisation patterns of a short day (SD) D...

Abstract The present investigation was carried out to decipher inheritance of resistance and identify linked SSR markers for Phomopsis blight in eggplant. An F 2 population comprising 161 plants developed from the cross Pusa Kranti BR‐40‐7. Genetic analysis using Chi square test. Artificial inoculation fruits pin prick method, scoring done as per standard scale. segregated into 92 susceptible (...

A large number of spores from fruiting bodies can lead to allergic reactions and other problems during the cultivation of edible mushrooms, including Pleurotus eryngii (DC.) Quél. A cultivar harboring a sporulation-deficient (sporeless) mutation would be useful for preventing these problems, but traditional breeding requires extensive time and labor. In this study, using a sporeless P. eryngii ...

BACKGROUND Common diseases may be attributed to combinations of variant alleles, but there are few model systems where the interactions among such variants can be studied in controlled genetic crosses. While association studies are designed to detect common polymorphisms of moderate effect, new approaches are required to characterize the impact on disease of interactions among rare alleles. M...
