Transcriptomic Analysis Reveals Distinct Strategies of Two Potato Cultivars Against Phytophthora infestans and Identifies StWRKY26 as a Positive Regulator of Late Blight Resistance

Project description:Late blight caused by Phytophthora infestans seriously threatens world’s potato production. Understanding the responsive mechanism of potato to P. infestans infection and exploring key regulators would be advantageous for improving the late blight resistance. Here, we assess the late blight resistance of various potato cultivars from Liangshan Yi Autonomous Prefecture and identified Chuan Liang Shu 10 (CLS) with strong resistant, while Bu Wu Yu (BWY) is highly susceptible. Comparative transcriptomics between these two cultivars upon P. infestans inoculation reveal that CLS activates defense pathways rapidly, while BWY prioritizes energy towards growth and development pathways, resulting in distinct late blight resistances. Specifically, the resistance of CLS might be contributed by enhanced oxidation-reduction process and SA signaling. Clustering analysis of the expression patterns for transcription factors (TFs) demonstrates that the WRKY family members play important roles in late blight resistance of CLS, among which StWRKY26 is identified as a positive regulator of late blight resistance. Silencing of StWRKY26 in CLS significantly compromise its intrinsic resistance to P. infestans. Our study enriches the knowledge of transcriptional responses of potato under P. infestans infection and provide candidate genes for breeding potato cultivars with strong late blight resistance.

RNA-Seq of allotetraploid wild potato Solanum acaule and autotetraploid potato Solanum tuberosum cv. Atlantic

Project description:Potato wild relatives (Solanum section Petota) are a source of genetic diversity for improving traits in modern cultivars (S. tuberosum) to meet climate challenges. Potatoes are susceptible to multiple abiotic and biotic stresses and have undergone constant improvement through breeding programs worldwide. The allotetraploid S. acaule Bitter has been used to introgress cold tolerance into potato breeding germplasm. The cold challenged transcriptome of S. acaule was compared with that of autotetraploid S. tuberosum cv. Atlantic, and was found to have fewer differentially expressed genes than the latter. Specifically, subgenome 1 has less downregulated alleles compared to subgenome 2 and S. tuberosum.

Transcriptome Analyses Reveal Molecular Responses of Three Potato (Solanum tuberosum L.) Cultivars to Cold Stress

Project description:Potato (Solanum tuberosum L.), as an important food crop on the Qinghai-Tibet Plateau, is prone to low temperature and frost damage during the seedling stage, causing economic losses for farmers. In this study, transcriptome analyses were conducted on the leaves of Atlantic, KY130 and KY140 potato varieties following exposure to cold stress (CS). The genes StPAL(Soltu.Atl.09_2G005110) and StGAD(Soltu.Atl.11_3G000340), suggesting their involvement in the regulation of cold resistance in potato. “Flavonoid-related metabolism,” “lipid metabolism,” “amino acid metabolism,” “carbohydrate metabolism,” “nucleotide metabolism,” and “energy metabolism” might play an important role in the cold resistance of potato. Our results provided novel insights into the molecular mechanisms underlying cold resistance in potato.

Potato Gene Expression Associated with the RB-mediated Broad-Spectrum late blight resistance

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 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.
