“…The relative expression of BrCMFs was significantly downregulated under short duration cold stress, and the expression of BrCMF15 of these genes was lowest under such conditions ( Figure 5 E, Table S3 ). Studies have shown that MeJA could promote reactive oxygen species (ROS) scavenging and contribute to the positive feedback regulation of melatonin (MT) to enhance the cold tolerance of plants [ 25 , 26 ], but BrCMF15 lacks MeJA-response elements. This is consistent with the high expression of the other genes according to the qPCR analysis.…”

CCT MOTIF FAMILY (CMF) genes belong to the CCT gene family and have been shown to play a role in diverse processes, such as flowering time and yield regulation, as well as responses to abiotic stresses. CMF genes have not yet been identified in Brassica rapa. A total of 25 BrCMF genes were identified in this study, and these genes were distributed across eight chromosomes. Collinearity analysis revealed that B. rapa and Arabidopsis thaliana share many homologous genes, suggesting that these genes have similar functions. According to sequencing analysis of promoters, several elements are involved in regulating the expression of genes that mediate responses to abiotic stresses. Analysis of the tissue-specific expression of BrCMF14 revealed that it is highly expressed in several organs. The expression of BrCMF22 was significantly downregulated under salt stress, while the expression of BrCMF5, BrCMF7, and BrCMF21 was also significantly reduced under cold stress. The expression of BrCMF14 and BrCMF5 was significantly increased under drought stress, and the expression of BrCMF7 was upregulated. Furthermore, protein–protein interaction network analysis revealed that A. thaliana homologs of BrCMF interacted with genes involved in the abiotic stress response. In conclusion, BrCMF5, BrCMF7, BrCMF14, BrCMF21, and BrCMF22 appear to play a role in responses to abiotic stresses. The results of this study will aid future investigations of CCT genes in B. rapa.

“…These candidate genes encoded receptor-like protein kinases (RLKs), tRNA ligase, MYB transcription factor, BAX inhibitor motif-containing protein (BI1) -like protein, Chaperone DnaJ-domain superfamily protein (DnaJ), serine/threonine-protein kinase, and some uncharacterized proteins. Importantly, homologs of some candidate genes have been shown to be involved in cold tolerance ( Shakiba et al., 2017 ; Davik et al., 2021 ; Han et al., 2022 ; Li et al., 2022 ). Then, we examined the expression levels of RLK , MYB and DnaJ in two parents, respectively.…”

“…In addition, the region also contained a serine/threonine protein kinase, the homolog of which is LRK10L1.2 , reported to be a good candidate for regulating the effects of freezing tolerance at the QTL identified in Fragaria vesca L. ( Davik et al., 2021 ). MYB transcription factors are associated with the mechanism of cold tolerance in other plants ( Shakiba et al., 2017 ; Han et al., 2022 ; Li et al., 2022 ). Reportedly, DnaJ co-chaperons also play a vital role in stress response and have been found to be involved in the maintenance of PSII under chilling stress and the enhancement of drought tolerance in tomato ( Kong et al., 2014 ; Wang et al., 2014 ).…”

Low temperatures significantly affect the growth and yield of peanuts. Temperatures lower than 12 °C are generally detrimental for the germination of peanuts. To date, there has been no report on precise information on the quantitative trait loci (QTL) for cold tolerance during the germination in peanuts. In this study, we developed a recombinant inbred line (RIL) population comprising 807 RILs by tolerant and sensitive parents. Phenotypic frequencies of germination rate low-temperature conditions among RIL population showed normally distributed in five environments. Then, we constructed a high density SNP-based genetic linkage map through whole genome re-sequencing (WGRS) technique and identified a major quantitative trait locus (QTL), qRGRB09, on chromosome B09. The cold tolerance-related QTLs were repeatedly detected in all five environments, and the genetic distance was 6.01 cM (46.74 cM - 61.75 cM) after taking a union set. To further confirm that qRGRB09 was located on chromosome B09, we developed Kompetitive Allele Specific PCR (KASP) markers for the corresponding QTL regions. A regional QTL mapping analysis, which was conducted after taking the intersection of QTL intervals of all environments into account, confirmed that qRGRB09 was between the KASP markers, G22096 and G220967 (chrB09:155637831–155854093), and this region was 216.26 kb in size, wherein a total of 15 annotated genes were detected. This study illustrates the relevance of WGRS-based genetic maps for QTL mapping and KASP genotyping that facilitated QTL fine mapping of peanuts. The results of our study also provided useful information on the genetic architecture underlying cold tolerance during germination in peanuts, which in turn may be useful for those engaged in molecular studies as well as crop improvement in the cold-stressed environment.

“…Exogenous application of ABA not only induces CsCOR1 expression but also rapidly close stomata to reduce water loss, thereby ABA effectively alleviates chilling damage to plant, consistent with the changes in proline content ( Li et al., 2010a ; Hong et al., 2017 ). As efficient elicitor, exogenous methyl jasmonate application induces the expression of CsMYBs , and thus effectively promotes ROS scavenging and anthocyanin biosynthesis to alleviate cold stress damage ( Han et al., 2022 ). Melatonin treatment alleviates cold stress on tea plant by improving biosynthesis antioxidant enzyme and antioxidant defense and redox homeostasis ( Li et al., 2018a ; Li et al., 2018b ; Li et al., 2019a ).…”

Tea is one of the most consumed and widely planted beverage plant worldwide, which contains many important economic, healthy, and cultural values. Low temperature inflicts serious damage to tea yields and quality. To cope with cold stress, tea plants have evolved a cascade of physiological and molecular mechanisms to rescue the metabolic disorders in plant cells caused by the cold stress; this includes physiological, biochemical changes and molecular regulation of genes and associated pathways. Understanding the physiological and molecular mechanisms underlying how tea plants perceive and respond to cold stress is of great significance to breed new varieties with improved quality and stress resistance. In this review, we summarized the putative cold signal sensors and molecular regulation of the CBF cascade pathway in cold acclimation. We also broadly reviewed the functions and potential regulation networks of 128 cold-responsive gene families of tea plants reported in the literature, including those particularly regulated by light, phytohormone, and glycometabolism. We discussed exogenous treatments, including ABA, MeJA, melatonin, GABA, spermidine and airborne nerolidol that have been reported as effective ways to improve cold resistance in tea plants. We also present perspectives and possible challenges for functional genomic studies on cold tolerance of tea plants in the future.
