“…Los valores de AIA mayores a 18 µg.mL -1 , fueron similares a los producidos en aislados provenientes de nódulos de leguminosas y suelo rizosférico por Mota et al (2014) y en cepas no rizobiales por Boukaya et al (2018) y Márquez et al (2020). Estos valores indican que las cepas rizobiales Leu2A, ME01, CP, ES1 y YE1 tienen potencial para ser usadas como bioestimulantes del crecimiento vegetal en campos cultivados, y que a nivel de umbráculo también pueden ser efectivas como lo demostraron Blanco et al (2018) con plántulas de pimentón y lechuga usando estas cepas de rizobios de forma individual, y Castro y Blanco (2018) y Blanco et al (2021) aplicando consorcios de estas cepas en plantas de pimentón y en plántulas de cebolla, respectivamente.…”

“…Los microorganismos antagonistas (bacterias y hongos) tienen la capacidad de ejercer un efecto de control biológico sobre diferentes fitopatógenos de interés y se han empleado para controlar diversas enfermedades en cultivos hortícolas. En cultivos comerciales las medidas de control se basan en el uso de agroquímicos, práctica que está variando a la implementación de controles biológicos con el propósito de proteger y mitigar el impacto sobre el medio ambiente (Agrios, 2005;Boukaya et al, 2018;Alcedo y Reyes, 2018;Márquez et al, 2020). Para implementar estas alternativas es necesario conocer la biología de los organismos que interactúan en los cultivos (Agrios, 2005).…”

Las rizobacterias forman parte de la gran cantidad de microorganismos que actúan como agentes de biocontrol, produciendo metabolitos que inducen resistencia sistémica en las plantas que inhiben el crecimiento de patógenos. El objetivo de esta investigación fue evaluar la capacidad de diez rizobacterias de los géneros Rhizobium, Bradyrhizobium, Sinorhizobium, Ochrobactrum y Pseudomonas para producir ácido cianhídrico (HCN), sideróforos y ácido indol-acético (AIA), disolver fosfato, fijar nitrógeno e inhibir el crecimiento de fitopatógenos. Se realizaron todas las pruebas fisiológicas y bioquímicas correspondientes, así como la prueba de antagonismo in vitro contra los fitopatógenos Fusarium oxysporum, Colletotrichum gloeosporioides y Rhizoctonia solani. Cinco cepas produjeron una mayor cantidad de AIA en relación a las otras en presencia de triptófano, la cepa ES1 (Ochrobactrum sp.) produjo HCN, el 50 % de las cepas evaluadas liberaron sideróforos, el 60 % disolvió fósforo, y todas resultaron positivas para la fijación de nitrógeno. Nueve cepas inhibieron el crecimiento de F. oxysporum entre 40 % y 65 %, la cepa Alf (Pseudomonas fluorescens) inhibió además el crecimiento de C. gloeosporioides en un 22 %, y ninguna inhibió el crecimiento de R. solani. Los rizobios evaluados y la cepa de Pseudomonas fluorescens podrían ejercer efectos beneficiosos sobre las plantas a través de mecanismos directos e indirectos, o una combinación de ambos, lo que las convierte en una opción sostenible para la producción de cultivos.

“…In addition, it was discovered that Streptomyces, as opposed to other bacterial species, could convert an insoluble phosphorous compound into its soluble form, allowing the plant to use it for assimilation. In addition, it shows that Streptomyces spiralis and Micromonospora chalcea were found to be efficient against Fusarium oxysporum, which is present in banana leaflets, and Streptomyces they showed a significant tendency to increase the production of IAA, which defines Streptomyces' capability to work with other species effectively [38].…”

Beneficial microorganisms have profound positive impacts on various human activities, including medicinal, pharmaceutical, and other biotechnological applications. This review provides an update about the potential of Streptomyces species as promising plant promoters because of their various roles as biofertilizers, biostimulators, biocontrol agents, and bioremediates. It also briefs the numerous mechanisms tackled by Streptomyces species, including the synthesis of plant growth regulators, siderophore production and secretion of the volatile compound to improve crop productivity. The percentage of increment in yield of different plants on inoculation with Streptomyces species is also outlined. Plant growth-promoting Streptomyces species are collectively Streptomyces highlighted as drivers for food security to satisfy global food demand.

Rhizoctonia oryzae Kühn and Fusarium spp. were isolated from wheat plants exhibiting typical root and crown rot symptoms from different districts at Sharkia Governorate, Egypt during 2015/ 2016 growing season. Pathogenicity test revealed that B. sorokiniana was the most virulent one causing preemergence damping-off followed by Fusarium culmorum. In addition, F. culmorum was the most virulent one responsible for post-emergence damping-off incidence. Rhizoctonia oryzae showed the highest percentage of root rot, Moreover, F. culmorum and B. sorokiniana showed the highest percentage of disease incidence. In the same trend, F. culmorum induce the highest percentage of disease severity. In vitro, Trichoderma sp. bio-agent and its culture filtrate were the most effective treatment that reduced mycelial growth of the tested fungi. In vivo, it decreased pre and postemergence damping off, root rot, disease incidence and disease severity compared with the control. In addition, the obtained results indicated a significant increase on healthy survival plants and significantly improved the plant growth parameters i.e. fresh and dry weights of shoots and roots, plant height, spike length and 1000 grain weight. In vitro, Score and Amistar-top fungicides were the most effective in inhibiting the mycelial growth of R. oryzae followed by Amistar-top on B. sorokinana and Score on F. culmorum. Score was the most effective treatment revealed the highest percentage of healthy survival plants followed by Amistar-top and gave the highest protection against root and crown rot disease as shown by disease incidence and severity percentages.
