| pantoea allii sp. nov., isolated from onion plants and seed. | eight yellow-pigmented, gram-negative, rod-shaped, oxidase-negative, motile, facultatively anaerobic bacteria were isolated from onion seed in south africa and from an onion plant exhibiting centre rot symptoms in the usa. the isolates were assigned to the genus pantoea on the basis of phenotypic and biochemical tests. 16s rrna gene sequence analysis and multilocus sequence analysis (mlsa), based on gyrb, rpob, infb and atpd sequences, confirmed the allocation of the isolates to the genus pantoe ... | 2011 | 20495023 |
| diversity and characterization of culturable bacterial endophytes from zea mays and their potential as plant growth-promoting agents in metal-degraded soils. | in this study, we evaluated the phylogenetic diversity of culturable bacterial endophytes of zea mays plants growing in an agricultural soil contaminated with zn and cd. endophytic bacterial counts were determined in roots and shoots, and isolates were grouped by random amplified polymorphic dna and identified by 16s ribosomal rna (rrna) gene sequencing. endophytes were further characterized for the production of plant growth-promoting (pgp) substances, such as nh3, siderophores, indol-3-acetic ... | 2014 | 25053283 |
