• Resumen

  • This project focuses on Brassica oleracea species, belonging to the Brassicaceae family, more specifically from the Brassica genus. The interest of this species lies in the fact that includes varieties of great agricultural interest in Europe, such as cauliflower, broccoli or cabbage, and also produces bioactive compounds, such as glucosinolates, of great interest for human health, due to its chemopreventive effects. Currently, for B. oleracea cultures, yield losses caused by pathogens, such as the bacterium Xanthomona campestris pv. campestris (Xcc). In this work it is proposed to study the effects of B. oleracea cultures infected in different phases (juvenile and adult plant) by Xcc, as well as the final quality of the products, performing glucosinolate analysis. Likewise, the molecular and metabolic bases involved in tolerance to the pathogen Xcc and biomass will be studied, through the analysis of physiological parameters (conductivity, photosynthesis, stomatal opening), accumulation of defense metabolites (glucosinolates, phenolic compounds), reserve substances ( starch , sugars), chlorophyll accumulation, antioxidant capacity ... etc. This thesis project is included in the RTI2018-096591-B-I00 R + D + i project, which aims to understand the genetic bases of resistance to Xcc, the relationship between glucosinolate content and resistance and metabolic and transcriptomic response against Xcc infection, knowledge that in the future could be used for genetic improvement that allows obtaining natural resistance against infection.
