“…The genus Methylobacterium have been studied for various plant growth promoting activities, and has been reported to positively influence the growth of various plants species (Krishnamoorthy et al, 2018;Poorniammal et al, 2020). Similar result was also observed in the present study where inoculation of M. salsuginis TNMB03 increased the plant height, girth and number of leaves, root length, lateral root and biomass in comparison to the uninoculated plantlets.…”

Aim: This study aimed to investigate the impact of M. salsuginis TNMB03 biotization on tissue culture banana cv. Grande Naine plantlets growth and survival under greenhouse and open environmental condition (exposed to direct sunlight). Methodology: Banana plantlets were transferred from culture flasks to protray and maintained under the greenhouse and open environmental condition for 30 days with or without M. salsuginis TNMB03 treatment. After 30 days, plant growth parameters like pseudostem height, girth, number of leaves, leaf area, fresh and dry biomass, root parameters, plantlet survival, chlorophyll a and b, total chlorophyll, carotenoids and soluble protein and Methylobacterium population in upper and lower surface of leaf, as well as endophytic population were assessed. Results: This study showed that the plantlets biotized with M. salsuginis TNMB03 had better acclimatization response under both the experimental condition than that of uninoculated plantlets. Positive influence on the survival and growth of M. salsuginis TNMB03 biotized plantlets was observed when transferred directly to greenhouse and open environmental condition. Inoculation of M. salsuginis TNMB03 increased the plant height, girth and number of leaves, root length, lateral root and biomass in comparison to the uninoculated plantlets in greenhouse and open environment. Uninoculated plantlets kept under open environment had lower chlorophyll content and sun scorching damages compared to M. salsuginis TNMB03 inoculated plants, which had dark green leaves and increased chlorophyll content. Interpretation: This study shows a new potential technique of using M. salsuginis TNMB03 in tissue culture plantlets, which can help in enhancing the growth of plantlets transferred from culture vessel to greenhouse or open environmental condition without undergoing the routine acclimatization procedure.

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

Bacteria belonging to the genus Methylobacterium, popularly known as pink pigmented facultative methylotrophic (PPFM) bacteria, are well known for their distinct ability to use single-carbon compounds like methanol, formate and formaldehyde, and also a variety of multi-carbon substrates lacking carbon-carbon bonds. These bacterial groups are ubiquitously distributed, especially in phyllosphere and rhizosphere, and their occurrence have been reported in more than 100 species of plants so far. PPFMs have profound influence on soil fertility, crop growth and yield. The ability for phosphate acquisition, nitrogen fixation, iron chelation and phytohormone production indicate the possibility of developing them as promising biofertilizer candidates. In addition, many of them possess biocontrol activity against several phytopathogens. PPFMs induce several physiological changes in plants, making the plants more resistant to biotic and abiotic stress. They can therefore be promising alternatives to conventional chemical inputs in sustainable agricultural systems.
