What bacterial strain is isolated in the healthy 10-day-old variety of maize with a high sugar content?
Elizabethkingia endophytica Elizabethkingia endophytica is a slightly yellow Gram-stain-negative rod-shaped bacterial strain isolated from the stem of healthy 10-day-old sweet corn ("Zea mays"). A comparison of the 16S rRNA gene sequence of the isolate showed 99.1, 97.8, and 97.4% similarity to the 16S rRNA gene sequences of the type strains of "Elizabethkingia anophelis", "Elizabethkingia meningoseptica" and "Elizabethkingia miricola", respectively. DNA-DNA hybridization indicated that the strain is representative of a new species.
Sinorhizobium meliloti Sinorhizobium meliloti is a Gram-negative nitrogen-fixing bacterium (rhizobium). It forms a symbiotic relationship with legumes from the genera "Medicago", "Melilotus" and "Trigonella", including the model legume "Medicago truncatula". This symbiosis results in a new plant organ termed a root nodule. The "S. meliloti" genome contains three replicons: a chromosome (~3.7 megabases), one chromid, pSymB (~1.7 megabases), and one megaplasmid pSymA (~1.4 megabases). Five "S. meliloti" genomes have been sequenced to date: Rm1021, AK83, BL225C, Rm41, and SM11
