WD40 domains have been found in a plethora of eukaryotic proteins, acting as scaffolding molecules assisting proper activity of other proteins, and are involved in multi-cellular processes. They comprise several stretches of 44-60 amino acid residues often terminating with a WD di-peptide. They act as a site of protein-protein interactions or(More)
Availability of complete Arabidopsis(Arabidopsis thaliana) and rice(Oryza sativa) genome sequences, together with molecular recourses of functional genomics and proteomics have revolutionized our understanding of reactive oxygen species (ROS) signalling network mediating disease resistance in plants. So far, ROS have been associated with aging, cellular and(More)
The arbuscular mycorrhizal (AM) symbiosis, formed between the majority of land plants and ubiquitous soil fungi of the phylum Glomeromycota, is responsible for massive nutrient transfer and global carbon sequestration. AM fungi take up nutrients from the soil and exchange them against photosynthetically fixed carbon (C) from the host. Recent studies have(More)
ANGUSTIFOLIA (AN), one of the CtBP family proteins, plays a major role in microtubule-dependent cell morphogenesis. Microarray analysis of mammalian AN homologs suggests that AN might function as a transcriptional activator and regulator of a wide range of genes. Genetic characterization of AN mutants suggests that AN might be involved in multiple(More)
The completion of the rice genome sequence has made it possible to identify and characterize new genes and to perform comparative genomics studies across taxa. The aldehyde dehydrogenase (ALDH) gene superfamily encoding for NAD(P)(+)-dependent enzymes is found in all major plant and animal taxa. However, the characterization of plant ALDHs has lagged behind(More)
The completion of maize genome sequencing has resulted in the identification of a large number of uncharacterized genes. Gene annotation and functional characterization of gene products are important to uncover novel protein functionality. In this paper, we identify, and annotate members of all the maize aldehyde dehydrogenase (ALDH) gene superfamily(More)
Rp1-D21 is a maize auto-active resistance gene conferring a spontaneous hypersensitive response (HR) of variable severity depending on genetic background. We report an association mapping strategy based on the Mutant Assisted Gene Identification and Characterization approach to identify naturally occurring allelic variants associated with phenotypic(More)
Previous studies have shown the role of melanized appressoria in the pathogenicity of various fungi. Diplocarpon rosae is a worldwide outdoor fungal pathogen of rose plants causing black spot disease of rose leaves. To fully understand how this fungus colonizes its host, which is critical for the development of an efficient and sustainable disease(More)
Genomic DNA extraction protocols generally require the use of expensive and hazardous reagents necessary for decontamination of phenolic compounds from the extracts. In addition, they are lengthy, hindering large-scale sample extractions necessary for high-throughput analyses. Here we describe a simple, time and cost-efficient method for genomic DNA(More)
Protocols for genomic DNA extraction from plants are generally lengthily, since they require that tissues be ground in liquid nitrogen, followed by a precipitation step, washing and drying of the DNA pellet, etc. This represents a major challenge especially when several hundred samples must be screened/analyzed within a working day. There is therefore a(More)
