“…significantly increased the seedling height of red pepper and tomato . Priya et al, (2019) reported that the effect of single strain of M. radiotolerans in groundnut significantly increase the root and shoot length when compared to un-inoculated control. Inoculation of methylotrophic bacteria significantly enhanced the plant parameters of root and shoot length on groundnut (Krishnamoorthy et al, 2019).…”

Tomato (Solanum lycopersicum) is widely cultivated vegetable crop and processed throughout the world which is highly susceptible to moisture stress. In this study Methylobacterium spp. viz., M. aminovorans and M. thiocyanatum were used to increase the moisture stress tolerance. Artificial moisture stress was induced to tomato seeds using Polyethylene Glycol (PEG) with concentration ranged from 0 to -3bars.The results showed that highest growth parameters were exhibited in tomato seedlings treated with M.thiocyanatum, where it exhibited maximum germination percentage at 0 bar (42.7%), vigor index at 0 bar (170.8), shoot length at -3bar (2.7 cm),root and seedling length at -2 bar (4.1cm, 5.1cm) followed by M.aminovorans, which showed germination percentage of 40% at (-1.5 bar), vigor index of 131.2 at (-1 bar), root, shoot and seedling length of 2.9cm, 1.9cm, 4.8cm at (-3 bar) respectively. Compared to treated seeds, the un-inoculated control showed lowest germination percentage at 0 bar (17.2%), vigor index (48.3), root, shoot and seedling length (1.7cm, 1.1cm, 2.2cm). Root hair deformation was observed in both treated seedlings which are grown under aseptic condition. In which, M. aminovorans performed well when compared to M. thiocyanatum. The activity of antioxidant enzymes catalase (CAT), peroxidase (PER), proline, glycine betaine (GB) and superoxide dismutase (SOD) were enhanced by M. aminovorans at -1.5 bars & M. thiocyanatum at -2 bars which have the ability to protect the plant under moisture stress conditions. Thus, Methylobacterium has the ability to mitigate drought stress and increase the drought tolerance of tomato crop. K e y w o r d sEnvironmental stresses, CO2 reduction, day neutral plant, tomato

Potentials, Utilization, and Bioengineering of Plant Growth-Promoting Methylobacterium for Sustainable Agriculture

Plant growth-promoting bacteria (PGPB) have great potential to provide economical and sustainable solutions to current agricultural challenges. The Methylobacteria which are frequently present in the phyllosphere can promote plant growth and development. The Methylobacterium genus is composed mostly of pink-pigmented facultative methylotrophic bacteria, utilizing organic one-carbon compounds as the sole carbon and energy source for growth. Methylobacterium spp. have been isolated from diverse environments, especially from the surface of plants, because they can oxidize and assimilate methanol released by plant leaves as a byproduct of pectin formation during cell wall synthesis. Members of the Methylobacterium genus are good candidates as PGPB due to their positive impact on plant health and growth; they provide nutrients to plants, modulate phytohormone levels, and protect plants against pathogens. In this paper, interactions between Methylobacterium spp. and plants and how the bacteria promote crop growth is reviewed. Moreover, the following examples of how to engineer microbiomes of plants using plant-growth-promoting Methylobacterium are discussed in the present review: introducing external Methylobacterium spp. to plants, introducing functional genes or clusters to resident Methylobacterium spp. of crops, and enhancing the abilities of Methylobacterium spp. to promote plant growth by random mutation, acclimation, and engineering.

El uso frecuente de fertilizantes de síntesis química acarrea graves problemas medioambientales, esto implica el uso de alternativas nutricionales para optimizar la producción del café en vivero, por lo que el empleo de bacterias promotores del crecimiento vegetal pudiera ser una alternativa de interés para estimular el desarrollo del cafeto. El objetivo de este trabajo fue evaluar la inoculación de cinco cepas de rizobios durante el proceso de obtención de plántulas de Coffea arabica cv. Isla 5-15 injertada sobre el patrón Coffea canephora cv. Robusta aviveradas bajo sombra natural, en relación a dos controles. Se realizaron dos inoculaciones una en las semillas antes de la siembra de las semillas de ambos cultivares y otra en el momento que se realizó el injerto hipocotiledonal, a través de la imbibición por uma hora y 30 minutos respectivamente. Se evaluó porcentaje de germinación; altura de la plántula, diámetro del tallo y número de hojas verdaderas, a partir de los 30 días después del trasplante y con frecuencia mensual hasta los 150 días. Al final del período experimental se evaluó la masa fresca y seca radical y foliar, se determinaron los índices de esbeltez y de Dickson. Las semillas y los injertos inoculados originaron plántulas que mostraron diferencias significativas y superaron los resultados mostrados por los dos controles empleados para todas las variables evaluadas. Estos resultados sugieren el empleo de cepas de rizobios para la producción de posturas de café en el contexto de una agricultura sostenible.
