| Abstract | In this report we address the changes in the expression of the genes involved in ROS scavenging and ethylene biosynthesis induced by the inoculation of plant growth-promoting rhizobacteria (PGPR) isolated from potato rhizosphere. The two Bacillus isolates used in this investigation had earlier demonstrated a striking influence on potato tuberization. These isolates showed enhanced 1-aminocyclopropane-1-carboxylic acid deaminase activity, phosphate solubilization, and siderophore production. Potato plants inoculated with these PGPR isolates were subjected to salt, drought, and heavy-metal stresses. The enhanced mRNA expression levels of the various ROS-scavenging enzymes and higher proline content in tubers induced by PGPR-treated plants contributed to increased plant tolerance to these abiotic stresses. Furthermore, the photosynthetic performance indices of PGPR-inoculated plants clearly exhibited a positive influence of these bacterial strains on the PSII photochemistry of the plants. Overall, these results suggest that the PGPR isolates used in this study are able to confer abiotic stress tolerance in potato plants. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
