“…For the activity of peroxidases, in the Coffea arabica-Hemileia vastatrix interaction, they decreased in those plants that presented disease symptoms compared with those that did not [38]. During infection, peroxidase activity did not change during the first days, presenting peaks from 5 days after infection, decreasing after 10 days, and increasing again 26 days after inoculation (39).…”

“…Therefore, biochemical and molecular changes were triggered, such as oxidative burst, cell wall lignification, callose deposition, increased PR proteins, hypersensitive response (HR), and phytoalexin accumulation [5,12]. In the Coffea arabica-Hemileia vastatrix interaction, the activity of β-1,3-glucanase decreased in those plants that showed symptoms of the disease compared to those that do not [38]. During the first days of infection, the activity of β-1,3glucanase decreased but increased 10 to 40 days after fungal inoculation [39].…”

“…Polyphenols are aromatic chemical compounds containing abundant phenolic groups that are divided into simple phenols, menolic acids, phenylpropenoids, coumarins, flavonoids, and tannins [42]. It has been reported that a higher proportion of polyphenols in coffee varieties may be associated with increased resistance to coffee leaf rust [42,43], although in susceptible varieties, there may be an increase in the content of total phenolic compounds during infection [38]. In this work, the application of PC chitosan increased the production of phenolic compounds after 48 h of pathogen inoculation, but this increase was not maintained after 72 h. Treatment with other elicitors, such as jasmonic acid, on coffee plants did not cause an increase in total phenolic compounds [43].…”

Chitosan is a natural polymer, and its biological properties depend on factors such as the degree of deacetylation and polymerization, viscosity, molecular mass, and dissociation constant. Chitosan has multiple advantages: it is biodegradable, biocompatible, safe, inexpensive, and non-toxic. Due to these characteristics, it has a wide range of applications. In agriculture, one of the most promising properties of chitosan is as an elicitor in plant defense against pathogenic microorganisms. In this work, four kinds of chitosan (practical grade, low molecular weight, medium molecular weight, and high-density commercial food grade) were used in concentrations of 0.01 and 0.05% to evaluate its protective effect against coffee rust. The best treatment was chosen to evaluate the defense response in coffee plants. The results showed a protective effect using practical-grade and commercial food-grade chitosan. In addition, the activity of enzymes with β-1,3 glucanase and peroxidase was induced, and an increase in the amount of phenolic compounds was observed in plants treated with high-molecular-weight chitosan at 0.05%; therefore, chitosan can be considered an effective molecule for controlling coffee rust.

“…Regarding varieties and their experimentation with the environment, due to the existence of coffee plants without rust, evaluation of the presence of phenolic compounds and proteins, following [ 121 ], is suggested. For this, spectrophotometric technology and sensors may be the best option to measure the presence of spores, aside from carbon, hydrogen, and oxygen, combined with the use of the technological platform to install in the context of the coffee plant.…”

The coffee plant, with more than 40 billion shrubs, 9 million tons of grains produced, and 80% of its production accounted for by small-scale producers, has been severely damaged since the emergence of Hemileia vastatrix and Hypothenemus hampei. Despite technological support, these pests have caused 20% to 40% production losses, a 50% to 60% deficit in performance, and a cost of between USD 70 million and USD 220 million to the world economies, which forces us to rethink actions centered on people as the key elements to develop appropriate solutions. For this, the present study presents a technological proposal centered on small indigenous coffee producer requirements for introducing Industry 5.0 technologies, considering roadmapping, knowledge management, statistical analysis, and the social, productive, and digital contexts of five localities in Mexico. The results show a correlation between monitoring and control, soil analysis, the creation of organic fertilizers, accompaniment, and coffee experimentation, as the actions to be implemented, proposing the introduction of a mobile application; sensors, virtual platforms, dome-shaped greenhouses, and spectrophotometric technology as relevant technologies centered on indigenous coffee producers’ requirements. This study is important for policymakers, academics, and producers who wish to develop strategies centered on people in Mexico and the world.

“…Al respecto, en Agave americana el tratamiento con EMS incrementó la actividad de la fenilalanina amonio liasa (PAL) y el contenido de metabolitos secundarios (Reyes et al, 2019). La PAL inicia la ruta de biosíntesis del ácido cafeico y ácidos clorogénicos, metabolitos presentes en el cafeto que son utilizados por la planta como defensa frente a patógenos (Luján-Hidalgo et al, 2020). El enanismo es un efecto característico después de la mutación en muchos cultivares, generando entrenudos cortos y reducción de algunas estructuras vegetativas (Rime et al, 2019;Chen et al, 2023), que pueden ser de utilidad agronómica en muchos cultivares.…”

El uso de metanosulfonato de etilo (EMS) es una tecnología utilizada para aumentar la variabilidad genética de cultivares. En el mejoramiento genético del cafeto, EMS podría generar nuevos rasgos fenotípicos y bioquímicos de importancia agrícola. El objetivo de la presente investigación fue determinar los cambios en la morfología y producción de metabolitos secundarios en plantas de cafeto generadas a partir de líneas celulares tratadas con EMS. Callos de Coffea arabica cv., Borbón fueron expuestos a nueve concentraciones de EMS, posteriormente, se determinó el porcentaje de supervivencia y la biomasa fresca. Se regeneraron plantas en medio MS suplementado con vitaminas, antioxidantes y 6-bencilaminopurina. A las 20 semanas se registraron cambios morfológicos observados con respecto a los callos no tratados con EMS. Empleando hojas secas se hizo la extracción de metabolitos secundarios, la cuantificación se realizó mediante cromatografía líquida de alta resolución. La supervivencia y crecimiento del callo disminuyó con el aumento de la concentración de EMS (dosis letal media: 148.8 mM), en plántulas generó cambios en la morfología de la hoja, enanismo y la formación de tres meristemas, que aumentarían el número de hojas. Finalmente, 140 mM de EMS incrementó el contenido de cafeína, ácido cafeico y ácido clorogénico.
