Respuesta del patógeno Xanthomonas campestris pv. campestris al tratamiento con allyl isotiocianato

Abstract

La podredumbre negra, causada por la bacteria Xanthomonas campestris pv. campestris (Xcc) es una de las enfermedades más importantes de los cultivos de brásicas a nivel mundial. La bacteria entra por los hidatodos y heridas de la planta, colonizando el rnesófilo. Una vez que las bacterias colonizan el sistema vascular de Ia planta pueden provocar su marchitez. El control de la enfermedad se realiza fundamentalmente mediante la siemba de semilla libre del patógeno. Los glucosinolatos son metabolitos secundarios que se encuentran en los cultivos de brásicas y les confieren resistencia frente a plagas y patógenos. Cuando hay una rotura de tejidos, la enzima mirosinasa hidroliza los glucosinolatos a isotiocianatos (ITCs). que son su forma activa. En un trabajo previo realizado en la Misión Biológica de Galicia (MBG-CSIC) se comprobó que los ITCs tenían un efecto antibiótico sobre Xcc (Sotelo et al., 2015). pero se desconocen los mecanismos moleculares por los cuales ejercen su toxicidad. El objetivo de este trabajo es profundizar en los procesos que tienen lugar en el patógeno después de interactuar con un ITC a través de una aproximación transcriptómica.
