| Abstract | Benzothiadiazole (BTH) is an artificial inducer of systemic acquired resistance. Due to rice being an important food crop and model plant, we investigated its response to BTH using label-free proteomics technology coupled with bioinformatics. Protein expression levels were verified using the multi-reaction monitoring mode and semi-quantitative RT-PCR. BTH treatment can up- or down-regulate many proteins produced by the rice host at all four periods, with the numbers of proteins being 6/24, 9/10, 14/10, and 8/20, respectively. Compared with mock treatments (phosphate buffered saline with 0.1 % dimethylsulfoxide and 0.5 % Tween-20), some proteins related to plant resistance were only detected after BTH treatments, such as ascorbate peroxidase (POD) 3, chitinase A, thioredoxin-dependent POD 2, beta-1,3-glucanase 2, POD superfamily protein, major facilitator superfamily (MFS) protein, copper/zinc-superoxide dismutase (SOD) 1, pathogenesis-related protein (PR) 1. Other proteins showing up-regulation after BHT treatment included PR-5, glyceraldehyde-3-phosphate dehydrogenase C, plasma-membrane associated cation-binding protein 1, and oxidoreductase family proteins. These results indicated that BTH was involved with inducing rice resistance. Some up-regulated proteins were also involved in other metabolic processes. The activity and expression level of POD, phenylalanine ammonia-lyase (PAL), and SOD, lipoxygenase (LOX), beta-1,3-glucanases, and chitinases were determined using the enzyme activity assay and semi-quantitative RT-PCR. These results indicated that BTH can enhance the activity of beta-1,3-glucanases, LOX, PAL, and POD. BTH can also induce up-regulation of the copper/zinc-SOD, ascorbate POD, glutathione POD 1, Chitinase, and LOX1 genes. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
