Genes specific to cowpea: cowpea vs adzuki bean

Project description:Comparative hybridization analysis Microarray-based genomic hybridization was used here as a high-throughput analog to traditional southern hybridization, which is the classical standard method for detecting specific DNA fragments in a genome.

Identification and analysis of microRNAs associated with drought tolerance in cowpea

Project description:To identify novel microRNAs that are associated with drought tolerance in two different cowpea genotypes, we generated small RNA sequences from adult cowpea plants under control and dought stress treatments. Over 79 million raw reads were generated and numerous novel microRNAs are identified, including some associated with drought tolerance.

Gel-free/label-free proteomic, biochemical and photosynthetic anaysis of cowpea resistance against Cowpea severe mosaic virus

Project description:In this present work, photosynthetic and biochemical parameters in conjunction with gel-free/label-free proteomic analysis were assessed in a resistant cowpea genotype challenged with CPSMV and compared with the corresponding data of the mock-inoculated control as an attempt to find out some clues to the molecular mechanims by which this cowpea genotype is resistant to CPSMV.

Transcriptional profiling of root-knot nematode induced feeding sites in cowpea (Vigna unguiculata L. Walp)

Project description:In this study we have looked at the transcriptome profile of both incompatible and compatible cowpea-RKN interaction for two different time points using the Affymetrix soybean GeneChip. This is the first study of this kind in cowpea-RKN interaction. This study provides a broad insight into the Rk-mediated resistance in cowpea and creates an excellent dataset of potential candidate genes involved in both nematode resistance and parasitism, which can be further tested for their role in this biological process using functional genomics approaches. our results have shown that the root-knot nematode resistant pathway is still partially suppressed at 9 days post inoculation in resistant cowpea root. There is indication that subtle variation of ROS concentration, induction of toxins and other defense related genes play a role in this unique resistance mechanism. Further functional analysis of these differentially expressed genes will help us to understand this intriguing plant-nematode interaction in a more precise manner.

Label-free Proteomics Reveals that Cowpea Severe Mosaic Virus Transiently Suppresses the Host Leaf Protein Accumulation During the Compatible Interaction with Cowpea (Vigna unguiculata [L.] Walp.)

Project description:Viruses are important plant pathogens that threaten diverse crops worldwide. Diseases caused by Cowpea severe mosaic virus (CPSMV) have drawn attention because of the serious damages they cause to economically important crops including cowpea. This work was undertaken to quantify and identify the responsive proteins of a susceptible cowpea genotype infected with CPSMV, in comparison with mock-inoculated controls, using label-free quantitative proteomics and databanks, aiming at providing insights on the molecular basis of this compatible interaction. Cowpea leaves were mock-inoculated or inoculated with CPSMV and 2 and 6 days later proteins were extracted and analyzed. More than 3000 proteins were identified and 75 and 55 of them differentially accumulated in response to CPSMV, at 2 and 6 DAI, respectively. At 2 DAI, 76% of the proteins were down-represented and 24% upaccumulated. However, at 6 DAI, 100% of the identified proteins were up-accumulated. Thus CPSMV transiently suppresses the synthesis of proteins involved particularly in the redox homeostasis, protein synthesis, defense, stress, RNA/DNA metabolism, signaling, and other functions, allowing viral invasion and spread in cowpea tissues. It is expected that identification of differentially accumulated proteins and their interactions advance our understanding on how a susceptible cowpea genotype responds to CPSMV infection.
