Original Paper


Plant endophytes play vital role in plant growth promotion as well as in abiotic and biotic stress tolerance. They also mediate biotransformation of complex organic materials to simpler and useful by-product. Therefore, the role of plant endophyte in plant growth promotion and stress tolerance has gained considerable attention in recent days. Sphingomonas sp. LK11 is an important plant endophyte that actively regulates plant growth. However, the biotransformation and stress tolerance potential of Sphingomonas sp. LK11 was yet to be elucidated. Therefore, we studied the biotransformation of benzoin by Sphingomonas sp. LK11. We found that, Sphingomonans sp. LK11 biotransformed benzoin to benzamide. Further application of benzamide to Cucumis sativus led to decrease in agronomic potential of C. sativus as benzamide acts as an abiotic stress agent. However, the application of Sphingomonas sp. LK11 inoculums with benzamide reverted back the agronomic trait of the plants, suggesting the role of Sphingomonas sp. LK11 in biotransformation and abiotic stress tolerance in plants.
