RNA-Seq of Tomato Fruit-Alternaria Chitin Oligomer Interaction Reveals Genes Encoding Chitin Membrane Receptors and the Activation of the Defense Response

The tomato is an economically important crop worldwide, although fungal infections by Alternaria alternata are the main cause of large postharvest fruit losses. One alternative to chemical control induction defense mechanism plants with natural molecules such as chitin. Chitin a polysaccharide cell wall that recognized plasma membrane receptors activates transcription plant genes. Because there little information on genes involved in chitin perception and responses oligomers fruits, objective this study was identify pattern recognition receptor-associated fruits perceive from necrotrophic fungus A. using RNA-Seq. were obtained via enzymatic treatment. Tomato pink ripening stage exposed these for 30 min. encoding receptor recognizes (LRR, RLK, SlLYK4, SlCERK1) observed min after Similarly, triggered signaling pathways regulated ethylene jasmonic acid. Further, activation phenomena confirmed upregulation several pathogenesis-related proteins. scientific generated present work will help better elucidate fruit’s response pathogens design protocols reduce losses due infection.
