The induction of general plant defense responses following the perception external elicitors is now regarded as first level immune response. Depending on involvement or not these molecules in pathogenicity, this called either Pathogen-Associated Molecular Pattern (PAMP) Triggered Immunity Immunity—both abbreviated to PTI. Because PTI assumed be a widespread and stable form resistance infection, understanding mechanisms driving it becomes major goal for sustainable management plant-pathogen...
Abstract Gas chromatography-mass spectrometry (GC-MS) represents an analytical technique with significant practical societal impact. Spectral deconvolution is essential step for interpreting GC-MS data. No public repositories that also enable repository-scale analysis exist, in part because requires user input. We therefore engineered a scalable machine learning workflow the Global Natural Product Social Molecular Networking (GNPS) platform to mass community store, process, share, annotate,...
The transcriptomic and metabolomic responses of peach to Myzus persicae infestation were studied in Rubira, an accession carrying the major resistance gene Rm2 causing antixenosis, GF305, a susceptible accession. Transcriptome metabolome showed both massive reconfiguration Rubira 48 hours after while GF305 displayed very limited changes. immune system was massively stimulated, with simultaneous activation genes encoding cell surface receptors involved pattern-triggered immunity cytoplasmic...
Abstract Each season, crops face simultaneous or successive multiple infections. Yet cultivar resistance is often bred against one pest at a time, and screened under single This raises the question of expression mono‐infections when exposed to We tackled this by measuring level quantitative potato cultivars either Globodera pallida Phytophthora infestans infections, using virus Y (PVY) Rhizoctonia solani as co‐infector. Overall, co‐infection resulted in less multiplication target pathogen...
Summary Pathogen recognition by plants via pathogen-associated molecular patterns leads to PAMP-triggered immunity. However, pathogens can modulate it the secretion of effectors. We hypothesize that in potato, induced defense triggered a Phytophthora infestans concentrated culture filtrate (CCF) could alter both effector expression and disease severity. CCF was sprayed onto three potato genotypes with different resistance levels, before inoculation P. . Symptoms were scored visually at 1-4...
