“…Knowing the nature of microbe and its connection with particular plants be useful to control diseases in plants. There are several mechanisms for plant-microbe interactions which vary from plant to plant and microbe to microbe as well [ 4 ]. The interaction can materialize in any part of the plants, may it be underground or above the soil.…”

“…For tests conducted in the greenhouse navel orange plants infected with HLB were irrigated with 1.5 L of B. amyloliquefaciens GJ1 (OD 600 ≈1) solution every week; after seven irrigations, the number of plants infected by the pathogen was reduced by 50% (Tang et al, 2018). It has been demonstrated that the ability to induce plant resistance or tolerance depends on the PGPB (Jain et al, 2014). To this regard, Riera et al (2018) tested the efficiency of seven bacterial isolates inoculated in ʻDuncanʼ grapefruit trees root to control citrus canker, and found that the Burkholderia territorri A63, B. metallica A53 and Pseudomonas geniculata 95 isolates significantly reduced the disease severity compared to that of the control plants.…”

“…En pruebas en invernadero, plantas de naranja navel enfermas de HLB fueron irrigadas con 1.5 L de la solución de B. amyloliquefaciens GJ1 (OD 600 ≈1) cada semana, después de siete irrigaciones, B. amyloliquefaciens GJ1 redujo el 50% de plantas con presencia del patógeno (Tang et al, 2018). Se ha demostrado que la capacidad para inducir resistencia o tolerancia en las plantas depende de la BPCP (Jain et al, 2014). Al respecto, Riera et al (2018) probaron la efectividad de siete aislamientos bacterianos inoculados a las raíces de árboles ʻDuncanʼ grapefruit en el control del cancro de los cítricos, encontrando que los aislados Burkholderia territorri A63, B. metallica A53 y Pseudomonas geniculata 95 redujeron significativamente la severidad de la enfermedad con respecto a las plantas control.…”

El Huanglongbing representa un gran reto para su control, por lo que se requiere de alternativas efectivas a la aplicación de insecticidas al insecto vector. La inducción de resistencia sistémica es una alternativa para disminuir el progreso de la enfermedad en árboles infectados. El objetivo de este trabajo fue evaluar el efecto de inductores de resistencia sistémica sobre la concentración de ?Candidatus Liberibacter asiaticus? (CLas) en árboles de limón mexicano (Lm) en condiciones de invernadero. Los inductores de resistencia utilizados fueron ácido salicílico (T1), Azospirillum brasilense Cd (T2) y quitosano (T3), aplicados cada 20 días durante ocho meses. La cuantificación de CLas fue mediante qPCR. La concentración de CLas se determinó a los 1, 2, 5 y 8 meses pos-tratamiento. A los 8 meses pos-tratamiento, T1 y T3 no presentaron diferencias postratamiento en la reducción postratamiento de la concentración de CLas con respecto al control sin inductor (T4) (6.5×103 células bacterianas/100 ng de ADN), mientras que T2 disminuyó casi tres veces la concentración de CLas con respecto al control. La inoculación directa al suelo de A. brasilense Cd mostró un efecto significativo en la reducción de la concentración de CLas en los árboles de Lm en condiciones de invernadero.

“…Other favorable but indirect actions of PGPRs on the rhizosphere include the biocontrol of phytopathogenic microorganisms via the production of substances like cianhidric acid (HCN), siderophores and antibiotics (Bakker et al, 2007). PGPR are also able to modulate plant stress by induced systemic tolerance (Jain et al, 2014) when plants are subject to abiotic adverse conditions such as high salinity, high temperatures and hydric stress. Some particular PGPRs such as Azospirillum sp.…”

The selection of microorganisms that enhance plant growth and confer biotic and abiotic tolerance to crops constitutes a biotechnology currently gaining importance on a global scale. The aim of this investigation was to evaluate the effects of inoculating rhizobacteria to lettuce (Lactuca sativa L.) on seed germination and vegetative development in order to use isolates as potential biofertilizers under tropical conditions. Five isolates of Pseudomonas fluorescens (Pf) and one of Azospirillum sp. (Az) were inoculated to seeds using a bacterial suspension of 1.5*10 8 CFU*mL -1 . In vitro, none of the isolates promoted germination. In vivo, isolates promoted growth and acted as stress alleviators by conferring tolerance to high temperatures (≥ 30 °C). The highest seedling emergence percentages were induced by the association of P.fluorescens with Azospirillum. This association also promoted the highest leaf-area in 25 d seedlings and exhibited a significantly higher dry-weight in 40 d plants compared to the control (P≤0.05) supporting the advantages of bio-consortiums over individual strains. The strains were able to produce dependent L-tryptophan indole-3-acetic acid (IAA), to solubilize phosphorous in vitro and tolerated at least 5%-salt stress. The results indicate that isolate Pf (26) and Az possess plant growth promoting rhizobacteria (PGPR) traits and should be further assessed. This study suggests that P. fluorescens and Azospirillum act synergically and are able to trigger an induced-tolerance mechanism in lettuce under abiotic stress.
