“…Estos resultados muestran el efecto positivo de la aplicación del EA, donde las plantas tratadas presentaron una reducción de daños entre el 66 y 73 %, comparado con la severidad presentada por las plantas control (heridas + inoculadas), lo que significa que los síntomas ocasionados por el hongo disminuyeron en las plantas tratadas. Este and Zeier (2013) and El Oirdi et al (2011), where these metabolites induced the expression of genes involved in plant defense under stress conditions. Based on this result, we can conclude that the exogenous application of EA acted as an activator of systemic acquired resistance in tomato plants.…”

Basado en este resultado se puede inferir que la aplicación exógena del EA funcionó como activador de la resistencia sistémica adquirida en las plantas de tomate.…”

“…El AJ es reconocido como un regulador clave para estimular en las plantas las respuestas de defensa en sinergia con el AS, reduciendo los síntomas de las enfermedades ocasionados por patógenos (Pieterse et al, 2012), mediante la activación en la expresión de genes involucrados en la defensa (Ryan, 2000). Específicamente, en plantas de tomate se ha reportado que el AJ induce inhibidores de proteasas y polifenoloxidasa y compuestos de la ruta de los fenilpropanoides, mostrando un efecto en la disminución de patógenos (El Oirdi et al, 2011). Es bien aceptado que las plantas requieren activar la resistencia sistémica inducida dependiente de AJ, para combatir patógenos necrotróficos (Glazebrook, 2005).…”

It has been reported that JA induces protease and polyphenol oxidase inhibitors, and shikimate pathway compounds specifically in tomato plants, which reduces pathogens (El Oirdi et al, 2011). It is well accepted that plants need to activate induced systemic resistance that depends on JA to fight necrotrophic pathogens (Glazebrook, 2005).…”

Resumen. Se evaluó un extracto de ajo (EA) para inducir la defensa de plantas de tomate contra Fusarium oxysporum radicis-lycopersici (Forl), mediante el incremento de la concentración endógena de ácido salicílico (AS) y ácido jasmónico (AJ). La aspersión de 1 y 2 % del EA sobre plantas intencionalmente infectadas con 1x10 7 esporas mL -1 de Forl, redujeron en 73.53% la severidad de la enfermedad producida por Forl respecto al control infectado. La altura fue similar (p≤0.05) en plantas tratadas con EA y no-tratadas. Abstract. A garlic extract (EA) was evaluated to induce the defense of tomato plants againstFusarium oxysporum radicis-lycopersici (Forl), by increasing the endogenous concentration of salicylic acid (AS) and jasmonic acid (AJ). Spraying 1 and 2% of EA on plants intentionally infected with 1x10 7 spores.mL -1 of Forl reduced in 73.53% the severity of the disease produced by Forl with respect to the infected control. The height was similar (p≤0.05) in plants treated with EA and untreated. The accumulation of AS in plants spayed with 1 and 2% of EA presented two significant increases (p≤0.05), in the second and fifth weeks after spraying, with higher concentrations than the infected and non-infected controls in 11 and 6 times for the first and 2.7 times and 3.8 times for the second, respectively. The AJ was induced from the first week after the treatments, increasing 2.5 and 1.8 times more than the infected and non-infected controls, maintaining those values throughout the evaluation. The results show that the EA reduced the development of the disease caused by Forl Publicación en línea, septiembre 2018 395Fully Bilingual Revista Mexicana de FITOPATOLOGÍA Mexican Journal of Phytopathology

“…Another biocontrol mechanism is the activation of the induced systemic resistance (ISR) in plants; this mechanism can be induced by elicitors released by the biocontrol agent (ranging a wide variety of molecules), and it has been attributed to non-pathogenic microorganisms associated to plants, such as saprophytes [61]. Generally speaking, microorganisms exhibit a combination of the mentioned mechanisms, thus reducing the risk of pathogen resistance [62].…”

Grapevine is one of the most abundant crops worldwide, with varieties destined for fresh and dry consumption, as well as wine production. Unfortunately, grapevine plants are affected by both biotic and abiotic stresses, generating significant economic losses. These conditions can negatively impact grape cultivation at different stages: plant and berry development during pre-and post-harvest, production, fresh fruit processing and export, along with wine quality. Most of the grapevine varieties are susceptible to several pathogens and within this chapter, particular attention is given to fungi (Botrytis cinerea and Erysiphe necator) and viruses, since they are a worldwide concern. Within the latter, special focus is given to the grapevine leafroll disease, a complex and destructive infection. On the other hand, abiotic stress is also relevant in grapevine, and in this chapter it will be exemplified by UV-B radiation and its impact on growth and fruit development, plant adaptive responses and its relationship with the quality of grape berries for winemaking. The main biotic and abiotic grapevine stress factors are reviewed in this chapter, considering a special focus on biotechnological approaches carried out in order to address them and minimize their detrimental consequences.

Microbial Pathogen Effectors in Plant Disease

Microbial plant pathogens use secreted effector proteins for successful infection of their host. This evolved state is rather exceptional as most microbes do not cause disease in the vast majority of plant species. An important primary activity of effectors is to interfere with a range of plant immune processes to evade and suppress pathogen detection, or to block immune signalling and downstream responses. Furthermore, effectors can enhance disease susceptibility by altering cellular processes and modulating host transcription. For most of these activities, effectors specifically target plant proteins that are central in these processes. An advanced virulence strategy is the post‐translational modification by effectors of plant targets to change their activity or stability. The knowledge gathered on the molecular mechanisms underlying effector‐triggered susceptibility of plants provides great potential for novel approaches of resistance breeding. Key Concepts Pathogens secrete and/or translocate effector proteins to promote plant disease. Besides their primary role in promoting disease, effectors or effector‐modified plant proteins can be recognised by resistance proteins to activate an effector‐triggered immune response. Many effectors block pathogen‐associated molecular pattern (PAMP)‐triggered immunity and/or effector‐triggered immunity. Other effectors rewire signalling pathways and reprogramme the plant cell to promote pathogen growth. Certain effectors can affect the activity or function of host proteins by post‐translational modifications e.g. (de)phosphorylation or targeting for proteosomal degradation.
