Erysiphe necator is the causal agent of powdery mildew (PM), one most destructive diseases grapevine. PM controlled by sulfur-based and synthetic fungicides, which every year are dispersed into environment. This why PM-resistant varieties should become a priority for sustainable grapevine wine production. resistance can be achieved in other crops knocking out susceptibility S-genes, such as those residing at genetic loci known MLO (Mildew Locus O). All S-genes dicots belong to phylogenetic...
Durable resistance to blast, the most significant fungal disease of rice, represents an agronomically relevant character. Gigante Vercelli (GV) and Vialone Nano (VN) are two old temperate japonica Italian rice cultivars with contrasting response blast infection: GV displays durable broad while VN is highly susceptible. RNA-seq was used dissect early molecular processes deployed during at 24 h after inoculation. Differential gene expression analysis identified 1,070 1,484 modulated genes,...
Both inter- and intra-specific maps have been developed in eggplant (Solanum melongena L.). The former benefit from an enhanced frequency of marker polymorphism, but their relevance to marker-assisted crop breeding is limited. Combining the restriction-site associated DNA strategy with high throughput sequencing has facilitated discovery a large number functional single nucleotide polymorphism (SNP) markers discriminating between two mapping population parental lines '305E40' '67/3'. A set...
Fusarium fujikuroi is the causal agent of bakanae, most significant seed-borne disease rice. Molecular mechanisms regulating defence responses rice towards this fungus are not yet fully known. To identify transcriptional underpinning resistance, a RNA-seq comparative transcriptome profiling was conducted on infected seedlings selected genotypes at one and three weeks post germination (wpg). Twelve were screened against bakanae leading to identification Selenio Dorella as resistant...
The huge size, redundancy, and highly repetitive nature of the bread wheat [Triticum aestivum (L.)] genome, makes it among most difficult species to be sequenced. To overcome these limitations, a strategy based on separation individual chromosomes or chromosome arms subsequent production physical maps was established within frame International Wheat Genome Sequence Consortium (IWGSC). A total 95,812 bacterial artificial (BAC) clones short-arm 5A (5AS) long-arm (5AL) arm-specific BAC...
In order to mitigate methane emissions from paddy fields, it is important understand the sources and sinks. Most fields are heavily fertilized with nitrite nitrate, which can be used as electron acceptors by anaerobic methanotrophs. Here we show that slurry incubations of Italian field soil nitrate 13C-labelled have potential for nitrate-dependent oxidation (79.9 nmol g-1dw d-1). Community analysis based on 16S rRNA amplicon sequencing qPCR water-logged rhizosphere showed methane-associated...
