ResumenEl ácido jasmónico (AJ) es una fitohormona endógena reguladora del crecimiento de plantas. Este se encuentra en muchas especies vegetales y está involucrado en diversas funciones de resistencia y senescencia, es producido por la planta después del daño ocasionado por un patógeno, el cual puede ser microorganismo o insecto, dando como resultado un incremento de la producción de compuestos de resistencia. La resistencia natural de las plantas a patógenos se basa en efectos combinados de barreras preformadas y mecanismos inducibles. Se ha comprobado que una compleja red de señales hormonales controla la respuesta de la planta frente al ataque de patógenos. Dependiendo del tipo de agente inductor, existen dos tipos de inducción de resistencia: biótica y abiótica y se activan dependiendo del tipo de daño generado.Palabras clave: fitohormona, jasmonatos, regulador de crecimiento vegetal.En su ambiente natural el ataque de u patógeno a las plantas es generalmente de poca importancia; sin embargo, la agricultura ha generado una cultura de monocultivo y de Abstract Jasmonic acid (JA) is an endogenous phytohormone that regulates plants growth. This is found in many plant species and is involved in various functions including resistance and senescence, is produced by the plant after damage caused by a pathogen, which can be a microorganism or an insect, resulting in an increase in the production of resistance compounds. The natural resistance of plants to pathogens is based on the combined effects of preformed barriers and inducible mechanisms. A complex network of hormone signals has been shown to control the plant's response to pathogen attack. Depending on the type of inducing agent, there are two types of resistance induction: biotic and abiotic, each activated depending on the damage type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
