Quantitative Trait Loci (QTL) Analysis Reveals Both Broad-Spectrum and Isolate-Specific QTL for Scab Resistance in an Apple Progeny Challenged with Eight Isolates of Venturia inaequalis.
ABSTRACT The major scab resistance gene Vf, extensively used in apple breeding programs, was recently overcome by the new races 6 and 7 of the fungal pathogen Venturia inaequalis. New, more durable, scab resistance genes are needed in apple breeding programs. F(1) progeny derived from the cross between partially resistant apple cv. Discovery and apple hybrid 'TN10-8' were inoculated in the gree...
متن کاملA cluster of four receptor-like genes resides in the Vf locus that confers resistance to apple scab disease.
The Vf locus, derived from the crabapple species Malus floribunda 821, confers resistance to five races of the fungal pathogen Venturia inaequalis, the causal agent of apple scab disease. In our previous research, the Vf locus was restricted to a BAC contig of approximately 290 kb covered by five overlapping BAC clones. Here, we report on cloning of the resistance gene(s) present in the Vf BAC ...
متن کاملDe Novo Transcriptome Sequencing and Analysis for Venturia inaequalis, the Devastating Apple Scab Pathogen
Venturia inaequalis is the causal agent of apple scab, one of the most devastating diseases of apple. Due to several distinct features, it has emerged as a model fungal pathogen to study various aspects of hemibiotrophic plant pathogen interactions. The present study reports de novo assembling, annotation and characterization of the transcriptome of V. inaequalis. Venturia transcripts expressed...
متن کاملSomatic variation plays a key role in the evolution of the Vf gene family residing in the Vf locus that confers resistance to apple scab disease.
A cluster of four receptor-like genes has been previously identified in the Vf locus of the crabapple Malus floribunda clone 821 that confers resistance to five races of the fungal pathogen Venturia inaequalis, the casual agent of apple scab disease. Pairwise comparisons of the four Vf paralogs in both promoter and coding regions reveal their timeline evolutionary history. The four Vf paralogs ...
متن کاملMetabolic and gene expression analysis of apple (Malus × domestica) carotenogenesis
Carotenoid accumulation confers distinct colouration to plant tissues, with effects on plant response to light and as well as health benefits for consumers of plant products. The carotenoid pathway is controlled by flux of metabolites, rate-limiting enzyme steps, feed-back inhibition, and the strength of sink organelles, the plastids, in the cell. In apple (Malus × domestica Borkh), fruit carot...
