Low temperature is one of the main environmental factors limiting plant growth and distribution, which not only affects the growth and development of plants and the quality of flowers and fruits, reduces their economic benefits, but even leads to plant death in severe cases.
Recently, a research paper entitled "Lysine malonylation of DgnsLIPID TRANSFER PROTEIN1 at the K81 site improves cold resistance in chrysanthemum" in Plant Physiology, revealing the molecular mechanism of non-specific lipid transfer proteins DgnsLTP1 and DgPIP in coordinating the regulation of chrysanthemum responses to low temperature stress.
When chrysanthemums are subjected to low temperature stress, both DgnsLTP1 and DgPIP can enhance their low temperature tolerance. Further research has found that DgnsLTP1 functions in a manner dependent on DgPIP. This study provides genetic resources for molecular breeding of chrysanthemum for low temperature resistance, and also provides reference for analyzing the biological function of lysine malonylation in plant response to low temperature stress.
