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.

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.

Time-course Investigation of Phytophthora infestans infection of potato leaf from three cultivars by quantitative proteomics

Project description:Potato Late blight is one the most important crop diseases worldwide. Even though potato has been studied for many years, the potato disease late blight still has a huge negative effect on the potato production. A total of three commercially available field potato cultivars of different resistance to late blight infection: Kuras (moderate), Sarpo Mira (highly resistant) and Bintje (very suseptable) under controlled green house growing conditions innoculated with a diversity of P. infestans populations. We used label-free quantitative proteomics to investigate the infection with P. infestans in a time-course study over 258 hours. Several key issues limits proteome analysis of potato leaf tissue4–6. Firstly, the immense complexity of the plant proteome which is further complicated by the presence of highly abundant proteins, such as ribulose bisphosphate carboxylase/oxygenase (RuBisCO). Secondly, plant leaf and potato in particular contain abundant levels amounts of phenols and polyphenols which hinder or, unless precautions are taken, completely prevent a successful protein extraction.
