“…At the same time, we observed a growth in the content of its oxidized forms (DAA and DKGA). There are data to suggest [5,[24][25][26] that AC contributes to the resilience of plants to adverse conditions and low temperatures. Therefore, an increase in the level of AC in the leaves of beach pea in that period is a form of plant adaptation to cold.…”

The article explores how location affected the dynamics of accumulation of ascorbic acid (AC) and oxidized forms of AC—dehydroascorbic acid (DAA) and diketogulonic acid (DKGA) in beach pea during ontogenetic development. Our analysis focuses on research of the ecological and geochemical conditions growing of the plant on the Curonian Spit. The level of hydrogen peroxide and the activity of enzymes that break it down were analyzed. Antioxidant activity and the total concentration of phenolics were evaluated in the leaves of beach pea on the leeward and windward sides of the foredune. It was established that the level of AC, DAA, and DKGA was higher in the plants growing on the windward side of the foredune. A higher concentration of peroxy compounds, which stimulate the biosynthesis of antioxidant enzymes (catalase, ascorbate peroxidase), polyphenols, and other low molecular antioxidants (AOA) was observed in the leaves of these plants. The plants on the windward side enter phenological stages one or two weeks later than their counterparts on the leeward side of the foredune do. There was a generally negative correlation between the temperature of the soil and the accumulation of ascorbate system acids in the leaves of the studied plants (r = −0.46/(−0.68), p < 0.05). The accumulation of low molecular antioxidants and enzymes in beach pea suggests their adaptation to the adverse conditions of the windward side of the foredune.

“…Transgenic A. thaliana were selected by PCR for subsequent testing. The activities of superoxide dismutase (SOD) and peroxidase (POD), soluble protein and malondialdehyde (MDA) content were determined by the enzyme-protein combination method (Yu et al, 2016) to detect the physiological responses of 35S:TaEXPA19-A and 35S:TaEXPA19-D A. thaliana to low-temperature treatment. To analyse the expression characteristics of the TaEXPA19 gene of transgenic A. thaliana, the RNA of the root, stem and leaf was extracted.…”

“…Previous research has indicated that significantly low temperatures (−16°C to −27°C) affect the yield of 90% of wheat varieties (Grabovets & Fomenko, 2015). Heilongjiang Province is located in northeast China, where low temperatures, severe winters and freezes are the main factors that restrict winter wheat planting and yield reductions (Tian et al, 2021; Yu et al, 2016). Winter wheat, which was cultivated over 13 years by the Northeast Agricultural University Crops Laboratory, can survive at temperatures as low as −30°C in the frigid region, and the regreening rate is greater than 85% for five consecutive years (Liu et al, 2013).…”

Low temperature is one of the main abiotic stresses that affects plant growth, causing serious damage or even death to plants. The differential expression of the TaEXPA19 gene in the above and underground parts of winter wheat and the implications for cold resistance remain unclear. In this study, the TaEXPA19 gene was cloned and analysed for expression in winter wheat, and transgenic Arabidopsis thaliana was constructed to investigate the effect of the TaEXPA19 gene in response to low‐temperature stress on plant growth. The TaEXPA19‐A and TaEXPA19‐D genes have different response patterns in the above and underground parts of transgenic A. thaliana. When plants were subjected to low‐temperature stress, the leaves were quickly upregulated and the roots were downregulated, and then upregulated to respond to low‐temperature stress to promote the growth of leaf length and leaf width petiole length. The results indicated that TaEXPA19 genes could improve low‐temperature tolerance in plants. The results of this study laid a foundation for the study of the cold resistance of winter wheat.

“…In addition, there is cross-regulation between low-temperature signaling and the plant hormone transduction pathway [ 13 ]. Salicylic acid (SA) mediates the low-temperature-induced grapevine bud dormancy release and effectively alleviates low-temperature inhibition in the growth of winter wheat [ 14 ]. Jasmonic acid (JA) positively regulates CBF signaling by mediating the interaction of ICE1 in Arabidopsis [ 15 ].…”

The sweet potato is very sensitive to low temperature. Our previous study revealed that IbMPK3-overexpressing transgenic sweet potato (M3) plants showed stronger low-temperature stress tolerance than wild-type plants (WT). However, the mechanism of M3 plants in response to low-temperature stress is unclear. To further analyze how IbMPK3 mediates low-temperature stress in sweet potato, WT and M3 plants were exposed to low-temperature stress for 2 h and 12 h for RNA-seq analysis, whereas normal conditions were used as a control (CK). In total, 3436 and 8718 differentially expressed genes (DEGs) were identified in WT at 2 h (vs. CK) and 12 h (vs. CK) under low-temperature stress, respectively, whereas 1450 and 9291 DEGs were detected in M3 plants, respectively. Many common and unique DEGs were analyzed in WT and M3 plants. DEGs related to low temperature were involved in Ca2+ signaling, MAPK cascades, the reactive oxygen species (ROS) signaling pathway, hormone transduction pathway, encoding transcription factor families (bHLH, NAC, and WRKY), and downstream stress-related genes. Additionally, more upregulated genes were associated with the MAPK pathway in M3 plants during short-term low-temperature stress (CK vs. 2 h), and more upregulated genes were involved in secondary metabolic synthesis in M3 plants than in the WT during the long-time low-temperature stress treatment (CK vs. 12 h), such as fatty acid biosynthesis and elongation, glutathione metabolism, flavonoid biosynthesis, carotenoid biosynthesis, and zeatin biosynthesis. Moreover, the interaction proteins of IbMPK3 related to photosynthesis, or encoding CaM, NAC, and ribosomal proteins, were identified using yeast two-hybrid (Y2H). This study may provide a valuable resource for elucidating the sweet potato low-temperature stress resistance mechanism, as well as data to support molecular-assisted breeding with the IbMPK3 gene.
