Plant Growth-Promoting Rhizobacteria (PGPR) as Protagonists of Ever-Sustained Agriculture: An Introduction

Draft genome sequence of halotolerant plant growth-promoting Bacillus paralicheniformis MHN12

“…Current management methods involve synthetic fungicides, leading to environmental issues ( 1 , 2 ). Stress-resilient plant growth-promoting endophytic bacteria offer an eco-friendly solution for sustainable plant growth and protection ( 3 ). The use of beneficial native microbes for promoting plant growth and protection is favored, as foreign strains often struggle to colonize and benefit host plants ( 4 ).…”

Respuesta agronómica del chile dulce (Capsicum annuum L.) a la aplicación de Bacillus subtilis y lombricomposta en invernadero

“…The increase in the vermicompost doses applied to the plants allowed the populations of B. subtilis to increase in sweet pepper roots (Figure 2), accounting for a greater number of the bacterium CFU with the highest dosage of vermicompost. To this respect, Singh et al (2012), Ammaan et al (2019) and Maheshwari et al (2019) mentioned that organic manure are important in increasing benef icial bacterial populations, which are a relevant factor in plant productivity. With respect to the plants chemically fertilized and inoculated with B. subtilis, the decrease of bacterial population might have been due to the negative effect of the fertilizer based on nitrogen and phosphorus, which decreased El aumento en las dosis de lombricomposta aplicadas en las plantas permitió que las poblaciones de B. subtilis se incrementaran en las raíces del chile dulce (Figura 2), contabilizando un mayor número de UFC de la bacteria con la dosis más alta de lombricomposta.…”

Al respecto, Singh et al (2012), Ammaan et al (2019) y Maheshwari et al (2019) mencionan que los abonos orgánicos son importantes en el incremento de las poblaciones bacterianas benéf icas, las cuales, son un factor relevante en la productividad de las plantas. En relación al tratamiento de las plantas fertilizadas químicamente e inoculadas con B. subtilis, la población bacteriana disminuyó probablemente al efecto negativo que puede representar el fertilizante a base de nitrógeno o fósforo, los cuales, disminuyen la población y actividad microbiana relacionada con la f ijación biológica de nitrógeno o la solubilización de fósforo, la cual, es signif icativa cuando estos elementos nutricionales son escasos en la rizósfera de las plantas (Nadeem et al, 2014;Chiquito-Contreras et al, 2017).…”

Plant Growth-Promoting Rhizobacteria (PGPR) as Biocontrol Agents for Viral Protection

“…This disruption can be minimized by the use of crop rotation or organic composts (biological ways). PGPR (plant growth-promoting rhizobacteria) is another method to compete with stresses influencing plant growth and development (Maheshwari et al 2019). PGPRs are generally defined as those bacteria living inside plant roots or their locale that promote the growth of plant (Kloepper et al 2004b).…”
