| Abstract | Increasing numbers of investigations indicate that ethylene response factor (ERF) proteins play important roles in plant stress responses via interacting with GCC box and/dehydration-responsive element/C-repeat to modulate expression of downstream genes, but the detailed regulatory mechanism is not well elucidated. Revealing the modulation pathway of ERF proteins in response to stresses is vital. Previously, we showed that tomato ERF protein TERF2/LeERF2 is ethylene inducible, and ethylene production is suppressed in antisense TERF2/LeERF2 tomatoes, suggesting that TERF2/LeERF2 functions as a positive regulator in ethylene biosynthesis. In this paper, we report that regulation of TERF2/LeERF2 in ethylene biosynthesis is associated with enhanced freezing tolerance of tobacco and tomato. Analysis of gene expression showed that cold slowly induces expression of TERF2/LeERF2 in tomato, implying that TERF2/LeERF2 may be involved in cold response through ethylene modulation. To test the hypothesis, we first observed that overexpressing TERF2/LeERF2 tobaccos not only enhances freezing tolerance via activating expression of cold-related genes, but also significantly reduces electrolyte leakage. In addition, with treatment of ethylene biosynthesis inhibitor or ethylene receptor antagonist, we then showed that blockage of ethylene biosynthesis or the ethylene signaling pathway decreases freezing tolerance of overexpressing TERF2/LeERF2 tobaccos. Moreover, the results from tomatoes showed that overexpressing TERF2/LeERF2 tomatoes enhances while antisense TERF2/LeERF2 transgenic lines decreases freezing tolerance, and application of ethylene precursor 1-aminocyclopropane-1-carboxylic acid restored freezing tolerance of antisense lines. Therefore our results establish that TERF2/LeERF2 enhances freezing tolerance of plants through ethylene biosynthesis and the ethylene signaling pathway. |

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.
