Description 571-579
In
this study, phylogeny and growth promoting attributes of bacterial endophytes isolated
from root tissue of seagrass were investigated. Sequence analysis of 16S rDNA
among the isolates displayed the presence of bacterial members affiliated

to
six different genera: Vibrio, Photobacterium, Bacillus, Aerococcus,
Saccharomonospora and Kocuria. Most of the isolates shared high level 16S
rDNA sequence similarity with bacteria previously reported from marine water
column, crustaceans, corals and terrestrial rhizosphere. Plant growth promoting
(PGP) attributes including ability to fix nitrogen, solubilize phosphate and
produce ammonia, acetoin and indolic compound were assessed in all the
isolates. Genetically diverse,

endophytic
isolates with different PGP abilities showed close relatedness with bacterial
inhabitants of marine ecosystem and likely to have ecological relevance. It
implies the need of further studies to validate the relationship between the
isolated

endophytes
and seagrass for sustenance of marine ecology.
