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.

Microarray analysis profiling of the effect of cowpea phenolic extract on gene expression in bovine peripheral blood in vitro

Project description:Plant-derived secondary metabolites found in animal feed sources are beneficial for nutrition and health. Cowpea is a protein and phenolic-rich forage used as feed resource in animal system. The objective of this study was to understand the effect of cowpea secondary metabolites on gene expression in cows blood in vitro. Whole blood collected from Holstein Friesian cows (n=5) were treated with 10 ug/ml of cowpea leaf phenolic extract and untreated samples served as control. Total RNA was isolated and pooled together for microarray analysis. The Agilent one color bovine (v2) 4x44KÂ array was used and preliminary gene expression profiles generated using Cy3 labeled cDNA from CPE-stimulated and untreated samples. Gene expression analysis revealed a total of 3170 differentially expressed genes- 1716 up regulated and 1454 down regulated genes respectively. Pathway analysis identified CPE treatment association with innate immune response pathways including Toll-like receptor (TLR) signaling pathway, the Wnt signaling pathway, inflammation response pathway, and increased expression of the transcription factor NFKB1 were observed. Treatment with CPE decreased the expression of proinflammatory cytokines IL1A, IL1B and IL21. Quantitative real time PCR was performed to validate some gene members of the Toll-like receptor, inflammation response and Wnt signaling pathways. In vitro treatment with CPE impacted global gene expression profile in cow blood and results obtained in this study shows the potential immuno-modulatory properties of cowpea feed phenolic in cows. The global gene expression of the effect of cowpea phenolic extract (CPE) was measured in bovine peripheral blood.The experiment involved two groups; cowpea phenolic extract (CPE) treated samples vs untreated control group. Pooled RNA samples from each group was hybridized on Agilent one color bovine (v2) 4x44KÂ microarray slides. Two slides were prepared each with 4 array compartment.
