Cold has a major impact on rice, so rice can only grow in specific climate zones. TMP14 (thylakoid membrane protein of 14 kDa) is a nuclear genome-encoded chloroplast thylakoid membrane protein, which is involved in a wide range of abiotic stress responses. However, the knowledge of TMP14 roles in response to adverse stimuli is still very limited in rice. Based on the results of expression profiles, OsTMP14 (GenBank accession: BAF27084.1) was highly induced in both leaf and panicle at all the developmental stages of rice analyses under cold and drought stresses. Sequence analyses of OsTMP14 putative promoter regions identified nine cis-elements related to stress responses. Furthermore, transgenic rice plants with overexpression of OsTMP14 showed more tolerance to cold stress. Taken together, these results indicate that OsTMP14 is involved in stress tolerance in rice, which is useful in developing transgenic rice with enhancing tolerance to cold stress.
