Project description:Genomic, tanscriptomic and metabolimic analyses of Amorphophallus albus provides insights into the evolution and resistance to southern blight pathogen
Project description:Southern corn leaf blight (SCLB), caused by Bipolaris maydis, poses a serious threat to maize production worldwide. In our previous study, Bacillus velezensis BV3 was isolated and demonstrated strong antagonistic activity against maize leaf spot pathogens and effective disease control in greenhouse experiments.
Project description:Late blight, caused by the oomycete Phytophthora infestans, is one of the most damaging potato diseases. Genetic resistance is one of the most effective means to control the destruction caused by this pathogen. Transgenic potato lines harboring a resistance gene, RB, confer broad-spectrum, rate-reducing late blight resistance. A microarray approach was used to understand what genes are manipulated in the potato background after the addition of the RB gene that contribute to the late blight resistant phenotype. Keywords: Time course, disease state analysis

Keywords: Time course, disease state analysis CRD (3x2x2) Split-Split Plot: 3 sampling time points after inoculation (2, 5, 10 hours), Two genotypes (Katahdin with and without the RB gene), Inoculation with P. infestans or mock inoculation with water. 48 arrays were hybridized in total; 12 in each biological replicate. Each genotype with the mock and late blight inoculated samples was hybridized on two arrays using a dye-swap procedure. Each genotype had a total of 6 arrays across the three sampling time points.
Project description:Bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most destructive diseases affecting rice production worldwide. In this study, the wild rice accession Oryza rufipogon Wild173 (UP36) exhibiting strong resistance to multiple Xoo strains was investigated in comparison with the susceptible rice cultivar Longjing-31 (CK2). To explore the molecular mechanisms underlying bacterial blight resistance, transcriptome sequencing (RNA-seq) was performed on leaf tissues collected from resistant and susceptible plants following inoculation with the Xoo strain PXO99A. Comparative transcriptomic analysis was conducted to identify differentially expressed genes associated with defense responses. The dataset provides insights into transcriptional reprogramming during pathogen infection and facilitates the identification of candidate genes and defense-related pathways involved in bacterial blight resistance in rice. These data provide valuable resources for understanding host–pathogen interactions and for improving disease resistance in rice breeding programs.
Project description:The project aimed to study the secretome profile of the Goss's bacterial wilt and blight disease of corn caused by the phytobacterial pathogen Clavibacter nebraskensis (Cn). The experiment was carried out in Vitro using two Cn isolates (A highly aggressive isolate Cmn14-5-1 and a weakly aggressive DOAB232) from Manitoba, Canada grown in two different xylem sap media (Host xylem sap from corn (CXS), and non-host xylem sap from tomato (TXS), besides M9 medium.
