“…Similar results were noted in endophyte inoculated cucumber plants that showed highest shoot length compared to control even under salinity stress (Waqas et al, 2012). Similarly, endophytes isolated from wheat plant were tested for colonization in non-host plant such as rice, which resulted in significant increase in root and shoot length (Jha and Kumar, 2009) and the EBIs when inoculated in corn seeds showed best enhancement in promoting plant growth such as root length and shoot length (Szilagyi-Zecchin et al, 2014).…”

“…According to Loon et al (2007), phytohormone production by microbes can alter the plant hormone levels and consequently have an influence on plant growth promotion. EBIs that produced auxin in lower amounts have greater influence on root elongation and root volume; because, only the plant growth inhibiting bacteria produces high concentration of auxin (Szilagyi-Zecchin et al, 2014). Taking together, we can interpret that the increased root growth activity is due to IAA production by EBIs.…”

Large amounts of chemical fertilizers are being used to enhance the growth and development of the rice (Oryza sativa L.) crop. Chemical fertilizers are too expensive; hence, endophytic bacteria with growth promoting activity can be considered to promote the crop plant growth to minimize the usage of chemical fertilizers and to have sustainable rice cultivation. This study was undertaken to explore the potential of endophytic bacterial isolates (EBIs) which were isolated previously. The objective of this study was to evaluate 800 EBIs for auxin-like activity and its effect on early seedlings growth of rice. Surface sterilized rice seeds were treated separately with different EBIs and allowed to grow in Petriplates (containing sterile cotton) for 10 days. On the 10 th day, the root length of the rice seedlings was measured and recorded to determine the auxin-like activity of EBIs. Results showed that 9 different isolates out of 800 EBIs screened to have significant effect on rice root and shoot growth when compared to control. The increase in root length was in the range of 58.30% to 81.68%, in comparison to root length of seedlings from control category. Based on the results, it was concluded that the positive root growth promoting response of rice seedlings could be due to the production of auxin-like compounds by the EBIs. These research findings could be useful in developing endophytic bacteria based formulation to enhance the growth of rice crop.

“…Evolutionary analyses were conducted in MEG 7 (Tamura et al, 2013;Kumar et al, 2016Kumar et al, ). al., 2007Mano and Morisaki, 2008;Cottyn et al, 2009;Kaga et al, 2009;Ji et al, 2014;Nhu and Diep, 2014 (Barka et al, 2002;Oliveira et al, 2003;Kang et al, 2007;Szilagyi-Zecchin et al, 2014). In addition, endophytic bacteria have been reported to be involved with other mechanisms such as competition for place and food, and antibiosis (Sturz et al, 2000;Reiter et al, 2002;Compant et al, 2005;Aravind et al, 2009;Ji et al, 2013).…”

Summary Endophytic bacteria of rice plants (Oryza sativa L.) from eight diff erent cultivars were screened for their ability in inducing disease symptoms, plant growth promotion and antagonistic activity against Xanthomonas oryzae pv. oryzae. Out of the 63 whole isolates, fi ve were plant pathogens. Based on phenotypic characteristics and 16S rDNA sequence analysis, these were identified as Pseudomonas oryzihabitans, P. fulva, Pantoea ananatis, Pantoea sp., Cellulomonas sp. Four out of the 63 isolates behaved as potentially good plant growth-promoting and biocontrol agents. These were identifi ed as Bacillus sp., B. subtilis, Pseudomonas putida and Enterobacter sp. This is the fi rst report of pathogenic and endophytic bacteria from rice grown in fi eld conditions in North of Iran.

RESUMOOs vegetais terrestres são colonizados por um amplo número de micro-organismos. Micro-organismos rizosférios, que ao colonizarem as adjacências das raízes, disponibilizam uma extensa quantidade de nutrientes através da decomposição da matéria orgânica e da ciclagem de nutrientes, além de melhorar a arquitetura radicular e protegerem o hospedeiro contra fitopatógenos. O objetivo deste trabalho foi triar bactérias isoladas de rizosfera de alface (Lactuca sativa), com a melhor capacidade de promover crescimento vegetal. Seis cepas isoladas da rizosfera de alface, pertencentes a bacterioteca do LAMAB/UFG foram triadas quanto a sua capacidade de produção de ácido idol-acético (AIA), solubilização de fosfato, fixação de nitrogênio, produção de enzimas, celulases e quitinases, formação de biofilme e por fim, teste de colonização radicular. Todos os isolados apresentaram pelo menos uma característica analisada, assim como todos foram capazes de produzir biofilme. O isolado AG4 obteve o maior índice de solubilização de fosfato, o isolado AG7 foi o que produziu o maior número de fatores de crescimento vegetal. Com exceção de AG1, todos os outros foram capazes de colonizar as raízes de alface. Dessa forma, os isolados Enterobacter cloacae (AG3), Enterobacter cancerogenus (AG5), Enterobacter ludwigii (AG7) são bons candidatos a inoculantes, pois além da capacidade em colonizar as raízes ainda são produtores de um grande número de fatores do crescimento vegetal. PALAVRAS-CHAVE: Fosfato, Lactuca sativa e Nitrogênio
