Summary: In apple, a novel B-box protein MdBBX37 positively regulates JA-mediated cold-stress resistance by activating the transcription of MdCBF1 and MdCBF4 and enhancing the transcriptional activity of MdICE1 on MdCBF1. Furthermore, two JA signaling repressors, MdJAZ1 and MdJAZ2, negatively regulate JA-mediated cold tolerance by interacting with MdBBX37. E3 ligase MdMIEL1 reduces MdBBX37-improved cold resistance through ubiquitination and degradation of MdBBX37 protein.

Summary: Although the effect of certain lipids on plant freezing tolerance is understood, the impact of many other plant lipids is still unknown. Pre-acclimating plants to non-freezing cold temperature before exposure to freezing temperatures can enhance the outcome of plants. A study on Arabidopsis thaliana plants under different treatments revealed correlations between lipid levels immediately post-freezing and ion leakage, allowing for hypotheses to be generated about the functions of specific lipids. Furthermore, analysis of lipid levels in plants with gene mutations identified differences in lipid composition in the opr3-2 mutant compared to wild-type plants under the same treatments.

Summary: The quality of light affects the response of Arabidopsis plants to cold treatment, with blue light enhancing the effect of low temperature and red light inducing higher expression of chloroplast-related proteins. Blue light mainly increased the expression of cold-stress-related proteins.

Summary: This study investigates the role of N (6)-methyladenosine (m6A) in response to low temperature in Arabidopsis. The results show that m6A modification plays a critical role in the chilling response and m6A-containing mRNAs have higher abundance and translation efficiency under normal and low temperatures. Reduction of m6A modification leads to dysregulation of the translation efficiencies of a significant number of genes in response to cold. The study also identifies a m6A-modified cold-responsive gene, DGAT1, whose translation efficiency is reduced under low temperature and affects the growth of Arabidopsis.

Summary: The indoor freezing tolerance selection method is useful for alfalfa breeders to accelerate breeding cycles through indirect selection. A total of 20 QTL associated with four traits were detected, with some QTL positions overlapping with previously reported WH QTL, suggesting a genetic relationship between FT and WH.

Summary: Previous studies have shown the post-translational modifications and protein stability regulation of ICE1 in cold stress, but the interaction of ICE1 with other transcription factors and their role in cold stress tolerance and transition to growth are not well understood. In this study, we found that MBP43 directly binds to the promoters of CBF genes to repress their expression, negatively regulating freezing tolerance. Furthermore, PRL1 promotes MYB43 protein degradation to attenuate its repression of CBF genes and antagonism with ICE1, thereby modulating plant cold stress responses.

Summary: This study successfully transformed cold-tolerant maize germplasm by introducing the ICE1 gene, resulting in increased tolerance to low temperature stress. Real-time quantitative PCR analysis showed ectopic expression of the ICE1 gene in the roots, stems, and leaves, and its positive regulation of CBF gene expression in response to cold stress.

Summary: Mother plants play a crucial role in determining the dispersal characteristics of their progeny by controlling seed dormancy. The study shows that the VEL3 histone deacetylase complex establishes an epigenetic state in the maternal plant, which regulates progeny seed dormancy. This mechanism involves the association of VEL3 with a histone deacetylase complex, preferential attachment to pericentromeric chromatin, and repression of specific genes to control seed behavior.
