“…Antagonistic microbes employ a number of methods to attack plant pests and pathogens. This includes, but is not limited to, the production of chitinases [61], the production of toxins (e.g., antibiotics and toxins), direct parasitism, competition for nutriment, and the induction of defense responses in the plant. Therefore, adding chitin-based products to the growing environment may aid beneficial antagonists by stimulating the production and activation of chitinases that can then be used to attack pests and pathogens, or be used as a stable nitrogen-rich polysaccharide food source that boosts the population to the level where other mechanisms control the plant pathogens.…”

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.

“…Alguno de los metabolitos bioactivos bacterianos puede suprimir la germinación, propagación o afectar otras actividades del desarrollo fúngico, tales como la actividad invasora, la supervivencia de los propágulos fúngicos anidados en hendiduras o superficie de la madera para evitar su dispersión (Figura 2). La mayoría de estos bioactivos bacterianos están catalogados en el grupo de antibióticos que inhiben la síntesis de pared celular y la síntesis de proteínas o alterar la estructura del sistema membranal microbiano o provocar la degradación del material genético del microorganismo diana (Maksimov et al, 2011). Algunas especies del género Bacillus producen antibióticos y proteínas insecticidas e.g.…”

“…Some of the bioactive metabolites may supress fungal germination, spreading, or affect other activities of fungal development, such as invasive activity, the survival of fungal propagules embedded in clefts or the surface of wood to avoid their spreading (Figure 2). Most of these bacterial bioactives are catalogued in the group of antibiotics that inhibit the syntheses of the cell wall and of proteins, or alter the structure of the microbial membrane system, or cause the degradation of the genetic material of the target microorganism (Maksimov et al, 2011).

Resumen. La madera de baja durabilidad es susceptible de deterioro por xilófagos y su protección es una meta tecnológica no alcanzada que genera pérdidas económicas y materiales. Alternativas para evitar el uso de preservadores convencionales tóxicos y contaminantes se pueden establecer mediante el conocimiento del microecosistema bacteriano en la madera. La protección de este material es posible obtenerla con bacterias y sus exudados. El propósito de esta investigación es destacar que el biodeterioro de la madera de baja durabilidad es evitable mediante estrategias microbiológicas relevantes para el control de los hongos xilófagos. La observación es que bacterias de los géneros Arthrobacter, Bacillus y Pseudomonas y sus exudados potencialmente son agentes de protección que exhiben mecanismos de acción diferentes como, el antagonismo, el parasitismo y la producción de exudados que contienen moléculas con efecto: antimicrobiano (antibióticos), quelante (sideróforos) que inhiben enzimas o funciones y compuestos volátiles (dimetilhexadecilamina). El conocimiento de este ecosistema microbiano facilitará la construcción de una alternativa al uso de los preservadores convencionales de madera y constituye un área de oportunidad. Se evidencia la ausencia del conocimiento de bacterias antagónicas de los xiló-fagos, el manejo de la producción y composición de sus exudados y su aplicación, con lo que se manifiesta un campo inexplorado en la biotecnología de la preservación de la madera.

“…Several authors have also reported increased potato yields from tubers treated with plant growth-promoting rhizobacteria, in particular pseudomonads, before planting (Grosch et al 2005;Rosyidah et al 2013;Vacheron et al 2013). Besides promoting plant growth, some strains of Bacillus, Methylobacter, Pseudomonas, Azospirillum, and combined treatment with vesicular arbuscular mycorrhizal fungi and Rhizobium influence stress resistance in plants and crop yields (Bensalim et al 1998;Dey et al 2004;Saleh and Saleh 2006;Maksimov et al 2011;Zaharchenko et al 2012;Pii et al 2015). A. brasilense Sp245 increases the resistance of wheat to osmotic stress by improving the plant's ability to absorb water and nutrients (Creus et al 2004) and promotes the formation of root hairs in tomato (Creus et al 2005).…”

Microclonal propagation in vitro is being actively used in the production of healthy planting material of food and ornamental plants. However, it needs further improvement to increase the growth rates of microclones in vitro and enhance regenerant survivability ex vitro. A promising approach to this end could be inoculating in vitro-micropropagated plants with plant growth-promoting rhizobacteria, specifically Azospirillum. However, the influence of Azospirillum inoculation on microclone behavior throughout the production process, including plant adaptation ex vitro and food crop productivity, has been underinvestigated. In this study, in vitrogrowing potato (Solanum tuberosum L.) microclones were inoculated with Azospirillum brasilense strain Sp245. The microclones were then grown on in soil in the greenhouse and field, with the experiment lasting for 120 days. Rootassociated bacteria were identified immunochemically, and the mitotic index of root meristematic cells was determined by a cytological method. The plant morphological parameters determined were shoot length, number of nodes per shoot, number of roots per plant, maximal root length, leaf area, percentage of surviving plants in the soil, and tuber yield and weight. Our results show that bacterial inoculation of potato microclones in vitro enhances plant adaptive capacity ex vitro and increases minituber yield. The percent survival index of field-grown inoculated plants was 1.5-fold greater than that of uninoculated plants. The overall tuber weight per plant was more than 30 % greater in the inoculated plants than it was in the control ones. For all cultivars on average, tuber yield per square meter increased by more than 45 % as a result of inoculation in vitro. This study is the first to report that Azospirillum inoculation of potato microclones not only improves the quality of planting material produced in vitro but also significantly increases minituber yield through enhancing plant adaptive capacity in the field.
