“…The environment worldwide is changing, with changes in temperature and humidity that significantly affect plant growth and development. Temperature is one of the important factors that limits the geographic distribution of organisms, and the tolerance to cold stress depends on their efficiency of physiological and cellular signal transduction mechanisms (Gao et al., 2020; Hajihashemi et al., 2020; Zhang et al., 2020). Low temperature has undesirable effects on plant morphogenesis (Sohag et al., 2020), while high humidity exacerbates such detrimental effects (Han et al .…”

Low temperature (LT) and high humidity (HH) are important environmental factors in greenhouses and plastic tunnels during the cold season, as they hamper plant growth and development. Here, we studied the effect of LT (day/night: 9/5 °C, 25/18 °C as control) and HH (95%, 80% as control) on young cucumber plants at the 2, 4 or 6 leaf stages. LT+HH stress resulted in a decline in shoot, root and total fresh and dry weights, and decreased Pn, gs, Tr, Fv/Fm, qP, ETR and chlorophyll, and increased MDA, H2O2, O2‐, NPQ and Ci as compared to the control at the 2 leaf stage. SOD, POD, CAT, APX and GR were upregulated under LT+HH stress as compared to the control at the 6 leaf stage. ABA and JA increased under LT+HH stress as compared to the control at the 6 leaf stage, while IAA and GA decreased under LT+HH stress as compared to the control at the 2 leaf stage. Our results show that LT+HH stress affects young cucumber plant photosynthetic efficiency, PSII activity, antioxidant defence system, ROS and hormone profile. Plants at the 6 leaf stage were more tolerant than at the 2 and 4 leaf stages under stress conditions.

“…Qiu et al obtained SlHY5 frameshift mutated and found that the anthocyanin content in the mutant was lower than that in wild-type tomato 20 . HY5 can improve plant cold tolerance through direct regulation of CBF or indirect regulation of MYB15 21 .Anthocyanins accumulation could be inhibited by Gibberellins at low temperature in plants, while the expression level of the gibberellin signaling pathway gene GA2ox1 showed HY5 -dependent 22 . In strawberry, HY5 - bHLH9 heterodimer formed to regulate light-dependent coloration and anthocyanin biosynthesis, suggesting that HY5 can be involved in plant anthocyanin metabolism by acting together with other genes 23 .…”

Ginkgo biloba L. is an ancient relict plant with rich pharmacological activity and nutritional value, and its main physiologically active components are flavonoids and terpene lactones. The bZIP gene family is one of the largest gene families in plants and regulates many processes including pathogen defense, secondary metabolism, stress response, seed maturation, and flower development. In this study, genome-wide distribution of the bZIP transcription factors was screened from G. biloba database in silico analysis. A total of 40 bZIP genes were identified in G. biloba and were divided into 10 subclasses. GbbZIP members in the same group share a similar gene structure, number of introns and exons, and motif distribution. Analysis of tissue expression pattern based on transcriptome indicated that GbbZIP08 and GbbZIP15 were most highly expressed in mature leaf. And the expression level of GbbZIP13 was high in all eight tissues. Correlation analysis and phylogenetic tree analysis suggested that GbbZIP08 and GbbZIP15 might be involved in the flavonoid biosynthesis. The transcriptional levels of 20 GbbZIP genes after SA, MeJA, and low temperature treatment were analyzed by qRT-PCR. The expression level of GbbZIP08 was significantly upregulated under 4°C. Protein–protein interaction network analysis indicated that GbbZIP09 might participate in seed germination by interacting with GbbZIP32. Based on transcriptome and degradome data, we found that 32 out of 117 miRNAs were annotated to 17 miRNA families. The results of this study may provide a theoretical foundation for the functional validation of GbbZIP genes in the future.

“…VvMYB15 was found to be transcriptional regulation of stilbene biosynthesis in grapevine ( Ciaffi et al, 2019 ). SlMYB15 has been found to be involved in the direct regulation of HY5 on CBF pathway and ultimate cold tolerance in tomato ( Zhang et al, 2020 ). And MYB15 has been found to be involved in regulating plant responses to environmental stresses, such as drought, salt, and cold, the lack of knowledge associated with the molecular regulatory mechanisms of VvMYB15 on anthocyanin accumulation in response to abiotic stress still needs further investigation.…”

In most grapevine planting regions, especially in south of China, plenty of rainfall and high water level underground are the characteristic of the area, a series of problem during fruit ripening easily caused poor color quality. Thereby affecting fruit quality, yield and economic benefits. The accumulation of anthocyanin is regulated by transcriptional regulatory factor and a series of cultivation measures, root restriction can make plants in the environment of stress and stress relief, root restriction induced the higher expression of VvMYB15 and VvWRKY40, and consistent with anthocyanin accumulation. Whether and how root restriction-inducible VvMYB15 and VvWRKY40 transcription factor regulate anthocyanin synthesis in grape berry is still unclear. In this study, we identified that the transient overexpression of VvMYB15 and VvWRKY40 alone or both in strawberry fruits and grape berries can promote anthocyanin accumulation and increase the expression level of anthocyanin biosynthetic genes, indicating VvMYB15 and VvWRKY40 play a positive regulator of anthocyanin biosynthesis. Furthermore, we confirmed that both VvMYB15 and VvWRKY40 specifically bind to the promoter region of VvF3′5′H and VvUFGT, and the expression of VvF3′5′H and VvUFGT is further activated through the heterodimer formation between VvMYB15 and VvWRKY40. Finally, we confirmed that VvMYB15 promoted anthocyanin accumulation by interacting with VvWRKY40 in grape berries, our findings provide insights into a mechanism involving the synergistic regulation of root restriction-dependent coloration and biosynthesis via a VvMYB15 and VvWRKY40 alone or both in grape berries.
