“…Trichoderma is capable of systemically activating plant defence mechanisms including priming, that anticipate pathogen attack [5,57,64,[66][67][68][69]. The reaction of the plant to the BCA is similar to the ISR elicited by rhizobacteria [70][71][72][73][74][75][76]. In fact, the ISR mechanism activated by Trichoderma is now considered to play a very significant role in crop protection as compared to the direct antagonism of the plant pathogens.…”

Governing bodies throughout the world, particularly in Europe, are now implementing legislative mandates with the objective of decreasing dependence on pesticides in agriculture to increase consumer and environmental safety. In order to reduce the risks associated with pesticide applications and reduce dependency on their use, Directives will promote low pesticide-input by implementing integrated pest management (IPM), and provide the means to establish the necessary conditions and measures to employ these practices, as well as to ensure security of commercial products. One approach includes the use of biological control agents and their products as alternatives to synthetic agro-chemicals. Trichoderma spp. are widely studied fungi and are among the most commonly used microbial biological control agents (MBCAs) in agriculture. They are presently marketed as bio-pesticides, biofertilizers, growth enhancers and stimulants of natural resistance. The efficacy of this fungus can be attributed to their ability to protect plants, enhance vegetative growth and contain pathogen populations under numerous agricultural conditions, as well as to act as soil amendments/inoculants for improvement of nutrient ability, decomposition and biodegradation. The living fungal spores (active substance) are incorporated in various formulations, both traditional and innovative, for applications as foliar sprays, pre-planting applications to seed or propagation material, post-pruning treatments, incorporation in the soil during seeding or transplant, watering by irrigation or applied as a root drench or dip. Trichoderma-based preparations are marketed worldwide and used for crop protection of various plant pathogens or increase the plant growth and productivity in diverse cultivated environments such as fields, greenhouses, nurseries; in the production of a variety of horticultural, fruits, trees and ornamental crops. A survey was conducted of Trichoderma-containing products found on the international market to obtain an overall perspective of the: 1) geographical distribution, 2) product composition and identity of Trichoderma species selected, 3) contents combined with Trichoderma in the products -other microbial species or substances in the mix, 4) number of products available globally and geographically, 5) number of products registered or having use specifications, 6) product formulations and applications, 7) manufacturer claims -target use, target pests, product type and effects of applications. The largest distribution of Trichoderma bioproducts is found in Asia, succeeded by Europe, SouthCentral America and North America. The majority of the labels indicated fungicidal properties, but only 38% of the marketed merchandise are registered. Ten Trichoderma species are specifically indicated, but many labels indicate a generic Trichoderma sp. or spp. mix in the list of ingredients. The most common formulation is a wettable powder, followed by granules. Generally, Trichoderma are applied to the seed or propagation material at...

Palabras clave: solubilización de fosfatos, producción de auxinas, microorganismos, crecimiento de plántula, Serratia RESUMENEn el cultivo de chile se usan altas dosis de fertilizantes que al no ser aprovechadas totalmente por las plantas ejercen efectos negativos en el ambiente. El uso de microorganismos benéficos puede ser una alternativa para disminuir las dosis de fertilizantes. En el presente trabajo se aislaron cepas de rizobacterias de la región de la Sierra Nevada, Puebla, México, con el objetivo de evaluar su potencial para promover el crecimiento de plántulas en chile poblano. Las cepas se caracterizaron por su capacidad de solubilizar fosfatos, fijar nitrógeno y producir auxinas. Las diez mejores cepas se evaluaron por su capacidad de promover el crecimiento en plántulas de chile poblano y finalmente éstas se identificaron a nivel molecular. Se aislaron un total de 215 cepas, de las cuales 74 fueron solubilizadoras de fosfatos que liberaron entre 10 y 881 µg/mL de fosfato soluble, 70 cepas tuvieron habilidad de crecer en medio libre de nitrógeno y 71 cepas produjeron entre 20 y 27 µg/mL de indoles. Las cepas inoculadas causaron efecto significativo en el crecimiento (Tukey, p < 0.05), siendo las mejores Serratia plymuthica CPPC55 y Rhizobium nepotum CPAC35, que incrementaron el peso de la parte aérea en más de 20 %. Ambas cepas pueden ser usadas para aumentar la calidad de plántulas de chile poblano, lo cual podría garantizar un mejor establecimiento y sanidad de éstas en campo. Las áreas cultivadas de chile poblano son una fuente de microorganismos que pueden ser utilizados como promotores del crecimiento en especies de importancia agrícola.Key words: phosphate solubilization, auxin production, soil microorganisms, seedling growth, Serratia ABSTRACTThe use of high doses of fertilizers is common in chilli pepper grown, which if are not fully utilized by plants, exerts negative effects on the environment.

Numerous root-associated bacteria (rhizobacteria) are known to elicit induced systemic resistance (ISR) in plants. Bacterial cell-density-dependent quorum sensing (QS) is thought to be important for ISR. Here, we investigated the role of QS in the ISR elicited by the rhizobacterium, Serratia marcescens strain 90−166, in tobacco. Since S. marcescens 90−166 produces at least three QS signals, QS-mediated ISR in strain 90−166 has been difficult to understand. Therefore, we investigated the ISR capacity of two transgenic tobacco (Nicotiana tabacum) plants that contained either bacterial acylhomoserine lactone-producing (AHL) or -degrading (AiiA) genes in conjunction with S. marcescens 90−166 to induce resistance against bacterial and viral pathogens. Root application of S. marcescens 90−166 increased ISR to the bacterial pathogens, Pectobacterium carotovorum subsp. carotovorum and Pseudomonas syringae pv. tabaci, in AHL plants and decreased ISR in AiiA plants. In contrast, ISR to Cucumber mosaic virus was reduced in AHL plants treated with S. marcescens 90−166 but enhanced in AiiA plants. Taken together, these data indicate that QS-dependent ISR is elicited by S. marcescens 90−166 in a pathogen-dependent manner. This study provides insight into QS-dependent ISR in tobacco elicited by S. marcescens 90−166.
