Insight Into

AbstractJasmonic acid (JA) plays an important role in regulating leaf senescence. However, the molecular mechanisms of leaf senescence in apple (Malus domestica) remain elusive. In this study, we found that MdZAT10, a C2H2-type zinc finger transcription factor (TF) in apple, markedly accelerates leaf senescence and increases the expression of senescence-related genes. To explore how MdZAT10 promotes leaf senescence, we carried out liquid chromatography/mass spectrometry screening. We found that MdABI5 physically interacts with MdZAT10. MdABI5, an important positive regulator of leaf senescence, significantly accelerated leaf senescence in apple. MdZAT10 was found to enhance the transcriptional activity of MdABI5 for MdNYC1 and MdNYE1, thus accelerating leaf senescence. In addition, we found that MdZAT10 expression was induced by methyl jasmonate (MeJA), which accelerated JA-induced leaf senescence. We also found that the JA-responsive protein MdBT2 directly interacts with MdZAT10 and reduces its protein stability through ubiquitination and degradation, thereby delaying MdZAT10-mediated leaf senescence. Taken together, our results provide new insight into the mechanisms by which MdZAT10 positively regulates JA-induced leaf senescence in apple.

AbstractThe purpose of the present investigation is to examine the function of the C2H2-type zinc finger transcription factor of Arabidopsis thaliana 6 (ZAT6) in salt stress tolerance in cells of rice (Oryza sativa L.), cotton (Gossypium hirsutum L.) and slash pine (Pinus elliottii Engelm.). Cells of O. sativa, G. hirsutum, and P. elliottii overexpressing ZAT6 were generated using Agrobacterium-mediated genetic transformation. Molecular and functional analysis of transgenic cell lines demonstrate that overexpression of ZAT6 increased tolerance to salt stress by decreasing lipid peroxidation and increasing the content of abscisic acid (ABA) and GA8, as well as enhancing the activities of antioxidant enzymes such as ascorbate peroxidise (APOX), catalase (CAT), glutathione reductase (GR), and superoxide dismutase (SOD). In rice cells, ZAT6 also increased expression of Ca2+-dependent protein kinase genes OsCPK9 and OsCPK25 by 5–7 fold under NaCl stress. Altogether, our results suggest that overexpression of ZAT6 enhanced salt stress tolerance by increasing antioxidant enzyme activity, hormone content and expression of Ca2+-dependent protein kinase in transgenic cell lines of different plant species.
