“…An adaptable bacteria might enter a plant via the tips of roots and hairs or small openings brought on by various factors in the epidermal tissues ( Compant et al., 2008 ; Hardoim et al., 2015 ). Previous reports have shown that Serratia can colonize certain crops, such as rice plants ( Gyaneshwar et al., 2001 , Cao et al., 2009 ). There aren’t any reports of Serratia colonizing the roots of lentils or other legumes.…”

Non-rhizobial endophytes (NREs) are active colonizers inhabiting the root nodules. Though their active role in the lentil agroecosystem is not well defined, here we observed that these NREs might promote the growth of lentils, modulate rhizospheric community structure and could be used as promising organisms for optimal use of rice fallow soil. NREs from root nodules of lentils were isolated and examined for plant growth-promoting traits, exopolysaccharide (EPS) and biofilm production, root metabolites, and the presence of nifH and nifK elements. The greenhouse experiment with the chosen NREs, i.e., Serratia plymuthica 33GS and Serratia sp. R6 significantly increased the germination rate, vigour index, development of nodules (in non-sterile soil) and fresh weight of nodules (33GS 94%, R6 61% growth) and length of the shoot (33GS 86%, R6 51.16%) as well as chlorophyll levels when compared to the uninoculated control. Scanning Electron Microscopy (SEM) revealed that both isolates could successfully colonize the roots and elicit root hair growth. The inoculation of the NREs resulted in specific changes in root exudation patterns. The plants with 33GS and R6 treatment significantly stimulated the exudation of triterpenes, fatty acids, and their methyl esters in comparison to the uninoculated plants, altering the rhizospheric microbial community structure. Proteobacteria dominated the rhizospheric microbiota in all the treatments. Treatment with 33GS or R6 also enhanced the relative abundance of other favourable microbes, including Rhizobium, Mesorhizobium, and Bradyrhizobium. The correlation network analysis of relative abundances resulted in numerous bacterial taxa, which were in cooperation with each other, having a possible role in plant growth promotion. The results indicate the significant role of NREs as plant growth promoters, which also includes their role in root exudation patterns, enhancement of soil nutrient status and modulation of rhizospheric microbiota, suggesting their prospects in sustainable, and bio-based agriculture.

Palabras clave: solubilización de fosfatos, producción de auxinas, microorganismos, crecimiento de plántula, Serratia RESUMENEn el cultivo de chile se usan altas dosis de fertilizantes que al no ser aprovechadas totalmente por las plantas ejercen efectos negativos en el ambiente. El uso de microorganismos benéficos puede ser una alternativa para disminuir las dosis de fertilizantes. En el presente trabajo se aislaron cepas de rizobacterias de la región de la Sierra Nevada, Puebla, México, con el objetivo de evaluar su potencial para promover el crecimiento de plántulas en chile poblano. Las cepas se caracterizaron por su capacidad de solubilizar fosfatos, fijar nitrógeno y producir auxinas. Las diez mejores cepas se evaluaron por su capacidad de promover el crecimiento en plántulas de chile poblano y finalmente éstas se identificaron a nivel molecular. Se aislaron un total de 215 cepas, de las cuales 74 fueron solubilizadoras de fosfatos que liberaron entre 10 y 881 µg/mL de fosfato soluble, 70 cepas tuvieron habilidad de crecer en medio libre de nitrógeno y 71 cepas produjeron entre 20 y 27 µg/mL de indoles. Las cepas inoculadas causaron efecto significativo en el crecimiento (Tukey, p < 0.05), siendo las mejores Serratia plymuthica CPPC55 y Rhizobium nepotum CPAC35, que incrementaron el peso de la parte aérea en más de 20 %. Ambas cepas pueden ser usadas para aumentar la calidad de plántulas de chile poblano, lo cual podría garantizar un mejor establecimiento y sanidad de éstas en campo. Las áreas cultivadas de chile poblano son una fuente de microorganismos que pueden ser utilizados como promotores del crecimiento en especies de importancia agrícola.Key words: phosphate solubilization, auxin production, soil microorganisms, seedling growth, Serratia ABSTRACTThe use of high doses of fertilizers is common in chilli pepper grown, which if are not fully utilized by plants, exerts negative effects on the environment.

This study was conducted to investigate both plant growth-promoting and plant disease-controlling activities of bacterial strains isolated from soil. All the isolated strains were able to grow at various temperatures. All the strains, except ANG40, showed antagonistic effects against various phytopathogenic fungi. This antagonism can be ascribed to the production of siderophores and antibiotic substances. In addition, all the strains showed abilities such as nitrogen fixation, phosphate solubilization, and siderophore production. These results suggest that nitrogen, phosphorus, and iron can be converted into forms that can be easily absorbed by the plants for their growth. Analysis of the growth-promoting properties revealed that ANG51 produced 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and indole-3-acetic acid (IAA) both of which are related to ethylene production. In contrast, the other strains were found to have only IAA-producing ability. Therefore, this study suggests that Pseudomonas geniculata ANG3, Exiguobacterium acetylicum ANG40, and Burkholderia stabilis ANG51, which were selected through analysis of comparative advantages for both plant growth promotion and disease-controlling activity, may be used as biological agents.
