Abstract

Endophytic bacteria play an important role in plant growth. In the present investigation, the authors examined the endophytic bacteria associated with tissues (root, stem, leaf) of Costus speciosus (J. Koenig) Sm. collected from the tropical deciduous forest of Meghalaya along with their plant growth promotion traits. Scanning electron microscopy and epifluorescence microscopic studies revealed the presence of bacterial cell internal to the tissues of the plant species. A total of 122 endophytic bacteria were isolated where the extent of colonization varied in plant parts. The molecular characterization of endophytic bacteria showed that bacterial communities associated with plant species are composed of 11 genera comprising actinobacteria, firmicutes and alpha-proteobacteria. Roots unveil the highest diversity and richness of endophytic bacteria, followed by leaf and stem. On evaluating the isolates for plant growth promoting properties, it was found that eight (8) isolates can produce both; indole acetic acid and siderophore, five (5) have phosphate solubilizing activity and six (6) have ACC deaminase activity. The results confirmed that Costus speciosus in tropical deciduous forest of Meghalaya encompasses diverse endophytic bacterial communities that could be potentially useful in promoting plant growth.
