| Abstract | Alternaria alternata f.sp. Lycopersici (AAL) toxin induces programmed cell death (PCD) in susceptible tomato (Solanum lycopersicum) leaves. Jasmonate (JA) promotes AAL toxin induced PCD in a COI1 (coronatine insensitive 1, JA receptor)-dependent manner by enhancement of reactive oxygen species (ROS) production. To further elucidate the underlying mechanisms of this process, we performed a comparative proteomic analysis using tomato jasmonic acid insensitive1 ( jai1), the receptor mutant of JA, and its wild type (WT) after AAL toxin treatment with or without JA treatment. A total of 10367 proteins were identified in tomato leaves using isobaric tags for relative and absolute quantitation (iTRAQ) quantitative proteomics approach. 2670 proteins were determined to be differentially expressed in response to AAL toxin and JA. Comparison between AAL toxin treated jai1 and its WT revealed the COI1-dependent JA pathway regulated proteins, including pathways related to redox response, ceramide synthesis, JA, ethylene (ET), salicylic acid (SA) and abscisic acid (ABA) signaling. Autophagy, PCD and DNA damage related proteins were also identified. Our data suggest that COI1-dependent JA pathway enhances AAL toxin induced PCD through regulating the redox status of the leaves, other phytohormone pathways and/or important PCD components. |

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.
