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.

Project description:The late blight pathogen, Phytophthora infestans has a broad host range within the Solanaceae family, including yellow potato (Solanum phureja). The disease caused by P. infestans in S. phureja is poorly understood and is a major concern in Colombia. Expressed Sequence Tag (EST) libraries obtained from a normalized library constructed from healthy plant tissue revealed high levels of sequence similarity between S. phureja and S. tuberosum. Then, utilizing Serial Analysis of Gene Expression and high-throughput sequencing (SAGE-Solexa), we characterized yellow potato gene expression during infection by P. infestans. Four-week-old yellow potato plants were inoculated with P. infestans and were collected at 12 and 72 hours post inoculation for RNA extraction. We detected differentially expressed genes by comparing inoculated to non-inoculated and resistant to susceptible plants. The discovery and characterization of the proteins mediating this host–pathogen interaction enable the understanding of the pathosystem and is the key for developing resistant plants. Keywords: SAGE-Solexa, inoculation response, transcript profiling, Solanum phureja, Phytophthora infestans Four-week-old yellow potato (Solanum phureja) plants were inoculated with Phytophthora infestans and were collected and flash frozen in liquid nitrogen at 12 and 72 hours post inoculation, as well as mock inoculated, for RNA extraction. 2 yellow potato cultivars (resistant and susceptible) were used for each experiment. Mock inoculated plants were collected in each replicate. RNA obtained from each of the three biological replicates was pooled to obtain a single RNA sample for each timepoint X cultivar combination. A total of 6 different SAGE libraries were thus obtained. For all libraries, Illumina sequencing was performed at Canada´s Michael Smith Genome Sciences Centre.

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.

Project description:Phytophthora spp. encode large sets of effector proteins and distinct populations of small RNAs (sRNAs). Reports suggest that pathogen-derived sRNAs can modulate the expression of plant defense genes. The experiments reported here were designed to shed light on impact of sRNAs in the potato-P. infestans interaction. We used the Argonaute or Ago1 from P. infestans tagged with GFP transformed into the 88069 strain to infect potato cv. Bintje plants. Collected leaf materials were used in co-immunoprecipitation experiments together with P. infestans harboring GFP (control GFP) and P. infestans mycelia grown on media (control mycelia). These three materials were sequenced at a Ion Proton platform. The reads length of 8-38 nt were adaptor-trimmed and mapped to the P. infestans genome and the Solanom tuberosum genome v4.04. Both P. infestans-associated and potato derived sRNAs were identified.
