Abstract
The present study investigated the phosphate solubilizing potential and in vitro plant growth-enhancing capability of five bacterial isolates of Pseudomonas sp. isolated from the endophytic region of three different weeds namely Cyperusrotundus, Amaranthus spinosus, Scirpus mucronatus which were collected from the coastal region of Bangladesh. The bacterial species were identified as Pseudomonas sp. based on their morphological characteristics. For further confirmation, molecular characterization will be done. The isolates of Pseudomonas sp. showed varying degrees of phosphate solubilizing potential on Pikovskaya's media. The results showed that isolate EnAgM3 had the utmost capability of phosphate solubilization with the competency of (77.43±0.65 %) and the second place was occupied by the isolate EnAgM2 with their competency of (74.92±0.95%). Then the isolates were used for the assessment of their in vitro growth-promoting capability of wheat (Triticum aestivum). Isolate EnAgM3 showed the best growth promotion in respect of all the parameters studied except root fresh ounce whereas EnAgM2 also significantly enhanced all the parameters except germination percentage in comparison to control. Conclusively, this study revealed that the unexplored coastal region of Bangladesh hold potential microorganisms having phosphate solubilizing and the potential of plant growth enhancement. As far as we know, it is the first comprehensive study conducted for isolating Pseudomonas sp. as the endophytic bacteria from the coastal weeds of Bangladesh and to identify their in vitro potential of phosphate solubilization as well as plant growth enhancement of wheat
