... Abstract. Phosphate-soubilizing bacteria (PSB) have the ability to colonize and associate with plant roots. An experiment was conducted to study the colonization and association of Bacillus spp. (PSB9 and PSB16 strains) on aerobic rice. Root colonization was examined under scanning and transmission ...

Pathogenicity islands can encompass very large genetic regions, sometimes spanning more than 100 kilobases (kb), and their frequent integration at or near tRNA loci suggests that many were introduced into bacterial genomes via phage-mediated transfer events (9, 11, 12, 13). This mobility would natur ...
