“…subtilis, including the production of phytohormones, delivery of nutrients and stimulation of the ISR (Beneduzi et al 2012;Pieterse et al 2014). In prior studies on tomato seedlings, B. subtilis has been shown to be effective in promoting growth which may be due to an increase in plant hormone production such as indole-3-acetic acid (IAA) and gibberellic acid (GA 3 ) (Chowdappa et al 2013;Cendales et al 2017). In our study, plants treated with B. subtilis subsp.…”

Main conclusion This study identified biocontrol measures for improving plant quality and resistance under biotic stress caused by the most devastating pathogen in tomato production. The management of plant diseases are dependent on a variety of factors. Two important variables are the soil quality and its bacterial/fungal community. However, the interaction of these factors is not well understood and remains problematic in producing healthy crops. Here, the effect of oak-bark compost, Bacillus subtilis subsp. subtilis, Trichoderma harzianum and two commercial products (FZB24 and FZB42) were investigated on tomato growth, production of metabolites and resistance under biotic stress condition (infection with Phytophthora infestans). Oak-bark compost, B. subtilis subsp. subtilis, and T. harzianum significantly enhanced plant growth and immunity when exposed to P. infestans. However, the commercial products were not as effective in promoting growth, with FZB42 having the weakest protection. Furthermore, elevated levels of anthocyanins did not correlate with enhanced plant resistance. Overall, the most effective and consistent plant protection was obtained when B. subtilis subsp. subtilis was combined with oak-bark compost. In contrast, the combination of T. harzianum and oak-bark compost resulted in increased disease severity. The use of compost in combination with bio-agents should, therefore, be evaluated carefully for a reliable and consistent tomato protection.

“…There are several studies demonstrating the ability of B. subtilis strains to promote plant growth in various ways under different conditions using different plant types (Podile and Dube, 1988;Mena-Violante and Olalde-Portugal, 2007;Lamsal et al, 2012). This could be related to IAA production and phosphate solubilization in the strains; however, other mechanisms could also influence the beneficial effects obtained in vivo (Cabra Cendales et al, 2017). Based on this study, a group of PSB could be considered proficient candidates for improving phosphate availability for crops.…”

Introduction Use of bacteria as a biofertilizer or biocontrol agent in agriculture became widespread in the late 1990s. Recently, the plant-growth-promoting and productivity enhancement properties of rhizobacteria have been studied worldwide. Agricultural policies that promote the use of environment friendly products, such as biofertilizers, have gained increasing importance nowadays (Chauhan et al., 2015). Commercial fertilizers containing strains of the genus Bacillus have been given considerable importance because they are more tolerant of extreme abiotic conditions, such as temperature, pH, and pesticides. Bacillus-based biofertilizers became a candidate for commercial production as they are not harmful to the environment and humans, play a role in biocontrol against pathogenic fungus, grow rapidly in the soil, and increase the nutrient uptake of plants to improve the productivity of plants (Kumar et al., 2011). Phosphorus is a main vital macronutrient for plants known to perform many functions in their growth and metabolism. Numerous important cellular, metabolic, and reproductive mechanisms depend on adequate phosphorus supply (Chen et al., 2006; Kaymak, 2010). Although soils contain sufficient amounts of phosphate, only a very small quantity is accessible to plants. The ability of the microorganisms to solubilize phosphate is a key character related to plant phosphate nutrition (Hayat et al., 2010; Bhattacharrya and Jha, 2012; Sharma et al., 2013). The process of phosphate solubilization by phosphatesolubilizing bacteria (PSB) strains is linked with the production of low molecular weight organic acids, via which hydroxyl and carboxyl groups chelate cations bind to phosphate; thus soluble phosphate is obtained (Chen et al., 2006). Various types of microorganisms have been used as phosphate-solubilizing biofertilizer (Malboobi et al., 2009). Production is a major property of plant growthpromoting bacteria (Mohite, 2013). IAA is one of the most physiologically active auxins. Bacteria synthesize auxins in order to perturb host physiological processes for their own benefit. The microorganisms isolated from the rhizosphere region of various crops can produce IAA. IAA

Sin embargo, varias cepas de Bacillus han sido evaluadas principalmente in vitro, de manera individual y en pocos estudios se han considerado los efectos de la aplicación de estos sobre la composición bromatológica de los frutos y su potencial para aminorar el daño indirecto en frutos causado por microorganismos fitopatógenos in situ (Esitken et al, 2010;Ju et al, 2014;El-Komy et al, 2015).…”

An alternative to promote the quality of tomato fruits (Solanum lycopersicon L.) and reduce the indirect effects of phytopathogenic fungi that cause root and crown diseases, might be the use of antagonistic bacteria of the Bacillus genus. The aim of the study was to determine the effect, of three Bacillus strains alone and together in interaction with phytopathogenic fungi on the plant growth promotion of tomato cv. Merlice and fruit quality. For this purpose, seedlings were inoculated with three Bacillus species (B. amyloliquefaciens, B. methylotrophicus and B. subtilis subsp. inaquosorum) and then with three phytopathogenic fungi of tomato (Alternaria solani, Fusarium oxysporum and Phytophthora infestans). At the end of the production cycle, the height and weight of plants, the length and weight of roots, chlorophyll in leaves, and Una alternativa para promover la calidad del fruto de jitomate (Solanum lycopersicon L.) y aminorar los efectos indirectos de hongos fitopatógenos causantes de enfermedades de raíz y cuello puede ser el uso de bacterias antagonistas del género Bacillus. El objetivo del estudio fue determinar el efecto de tres cepas de Bacillus solas y en interacción con tres hongos fitopatógenos en la promoción del crecimiento de plantas de jitomate cv. Merlice y calidad del fruto. Para este propósito, se inocularon plántulas con tres especies de Bacillus (B. amyloliquefaciens, B. methylotrophicus y B. subtilis subsp. inaquosorum), y después con tres hongos fitopatógenos del jitomate (Alternaria solani, Fusarium oxysporum y Phytophthora infestans). Al final del ciclo de producción, se determinaron, la altura y peso de las plantas; longitud y peso de raíces; y clorofila en hojas y el rendimiento. Los frutos cosechados se caracterizaron por color, peso, tamaño, espesor del mesocarpio, sólidos solubles totales, acidez titulable, composición bromatológica, firmeza, y número y peso de semillas.
