Steroidal glycoalkaloids (SGAs) are major secondary metabolites constitutively produced in cultivated potato Solanum tuberosum, and α-solanine α-chaconine the most abundant SGAs. SGAs toxic to humans at high levels but their role plant protection against pests pathogens is yet be established. In this study, of were reduced by RNA interference (RNAi)-mediated silencing GLYCOALKALOID METABOLISM 4 (GAME4)-a gene encoding cytochrome P450, involved an oxidation step conversion cholesterol SGA...
One or more effectors in the labial saliva (LS) of generalist Noctuid caterpillars activate plant signaling pathways to modulate jasmonate (JA)-dependent defense responses; however, exact mechanisms involved have yet be elucidated. A potential candidate this phytohormone interplay is ethylene (ET) pathway. We compared biochemical and molecular responses model legume Medicago truncatula ET-insensitive skl mutant herbivory by fourth instar Spodoptera exigua (Hübner) with intact impaired LS...

Increased atmospheric carbon dioxide (CO2) levels predicted to occur before the end of century will impact plant metabolism. In addition, nitrate availability affect metabolism and nitrogen-containing defense compounds, such as glucosinolates (GSLs). We compared Arabidopsis foliar metabolic profile in plants grown under two CO2 regimes (440 vs 880 ppm), fertilization (1 mM 10 mM) response mechanical damage rosette leaves. Constitutive metabolites nitrate-limited show distinct global patterns...
Verticillium dahliae Kleb. is a pathogenic fungus causing wilting, chlorosis, and early dying in potato ( Solanum tuberosum L.). Genetic mapping of resistance to V. was done using diploid population potato. The major quantitative trait locus (QTL) for found on chromosome 5. StCDF1 gene, controlling earliness maturity tuberization, mapped within the interval. Another QTL 9 co‐localized with Ve2 wilt gene marker. Epistasis analysis indicated that loci chromosomes 5 had highly significant...
