“…During plant invasion, bacterial cells may produce hydrolytic enzymes that are recognized by the plant, triggering the plant's resistance system. Trotel-Aziz et al (77) reported an increase in the resistance of vines against Botrytis cinerea due to the augmentation of chitinases and other compounds induced by the inoculation of the P. agglomerans strain PTA-AF1.…”

eThe promotion of sugarcane growth by the endophytic Pantoea agglomerans strain 33.1 was studied under gnotobiotic and greenhouse conditions. The green fluorescent protein (GFP)-tagged strain P. agglomerans 33.1::pNKGFP was monitored in vitro in sugarcane plants by microscopy, reisolation, and quantitative PCR (qPCR). Using qPCR and reisolation 4 and 15 days after inoculation, we observed that GFP-tagged strains reached similar density levels both in the rhizosphere and inside the roots and aerial plant tissues. Microscopic analysis was performed at 5, 10, and 18 days after inoculation. Under greenhouse conditions, P. agglomerans 33.1-inoculated sugarcane plants presented more dry mass 30 days after inoculation. Cross-colonization was confirmed by reisolation of the GFP-tagged strain. These data demonstrate that 33.1::pNKGFP is a superior colonizer of sugarcane due to its ability to colonize a number of different plant parts. The growth promotion observed in colonized plants may be related to the ability of P. agglomerans 33.1 to synthesize indoleacetic acid and solubilize phosphate. Additionally, this strain may trigger chitinase and cellulase production by plant roots, suggesting the induction of a plant defense system. However, levels of indigenous bacterial colonization did not vary between inoculated and noninoculated sugarcane plants under greenhouse conditions, suggesting that the presence of P. agglomerans 33.1 has no effect on these communities. In this study, different techniques were used to monitor 33.1::pNKGFP during sugarcane cross-colonization, and our results suggested that this plant growth promoter could be used with other crops. The interaction between sugarcane and P. agglomerans 33.1 has important benefits that promote the plant's growth and fitness.

“…Pantoea agglomerans is known in plant production as a biocontrol agent. It is used in postharvest control of a number of fungi (for instance, Penicillium expansum, Rhizopus stolonifer, Monilinia laxa, and Botrytis cinerea) on a wide variety of fruits (18,44,45,54). Some strains of P. agglomerans or E. herbicola have been reported to produce an antibiotic compound against Erwinia amylovora, the cause of fire blight on apple and pear trees, and can be used in orchards (24,26,47).…”

Pantoea agglomerans is a common soil bacterium used in the biocontrol of fungi and bacteria but is also an opportunistic human pathogen. It has been described extensively in this context, but knowledge of bacteriophages infecting this species is limited. Bacteriophages LIMEzero and LIMElight of P. agglomerans are lytic phages, isolated from soil samples, belonging to the Podoviridae and are the first Pantoea phages of this family to be described. The double-stranded DNA ( Pantoea agglomerans bacteria are Gram-negative, nonsporulating, facultatively anaerobic rods that belong to the family of the Enterobacteriaceae. Synonyms of this species name are Enterobacter agglomerans, Erwinia herbicola, and Erwinia milletiae (6, 19). The genus name Pantoea is derived from the Greek word pantoios, which means "of all sorts and sources," a descriptor well reflected in the habitat, since species of the genus have been isolated from plant surfaces, seeds, water, soil, and even humans and animals (3,19,41). Pantoea agglomerans is known in plant production as a biocontrol agent. It is used in postharvest control of a number of fungi (for instance, Penicillium expansum, Rhizopus stolonifer, Monilinia laxa, and Botrytis cinerea) on a wide variety of fruits (18,44,45,54).
