“…Similarly, PtrbHLH positively regulates freezing tolerance by directly binding to the PtrPOD and CATALASE ( PtrCAT ) promoters. ,, Recently, CabHLH79 has been identified as an upstream regulator of CaNAC035 regulating cold stress . In Solanum tuberosum , StICE1 can enhance plant tolerance to cold stress through StLTI6A -mediated cell membrane stabilization . Additionally, Wang et al indicated that two key components in ABA signaling, HbSnRK2.6 A/B, promote the transcriptional activity of HbICE2 , thereby enhancing cold tolerance.…”

Abiotic stresses including cold, drought, salt, and iron deficiency severely impair plant development, crop productivity, and geographic distribution. Several bodies of research have shed light on the pleiotropic functions of BASIC HELIX− LOOP−HELIX (bHLH) proteins in plant responses to these abiotic stresses. In this review, we mention the regulatory roles of bHLH TFs in response to stresses such as cold, drought, salt resistance, and iron deficiency, as well as in enhancing grain yield in plants, especially crops. The bHLH proteins bind to E/G-box motifs in the target promoter and interact with various other factors to form a complex regulatory network. Through this network, they cooperatively activate or repress the transcription of downstream genes, thereby regulating various stress responses. Finally, we present some perspectives for future research focusing on the molecular mechanisms that integrate and coordinate these abiotic stresses. Understanding these molecular mechanisms is crucial for the development of stress-tolerant crops.

“…Overexpression of PtrbHLH, a basic helix-loop-helix transcription factor from Poncirus trifoliata, confers enhanced cold tolerance in pummelo (Citrus grandis) by regulating CAT to modulate the level of H 2 O 2 [58]. Under cold conditions, StICE1 of potato enhanced the stability of cell membranes by upregulating the expression of the StLTI6A gene, thereby increasing its tolerance [59]. The MYC-type TF MdbHLH4 negatively regulates apple cold tolerance by inhibiting the expression of MdCBF1/3 and the promoter-binding activity of MdICE1L, as well as by promoting the expression of MdCAX3L-2 and the cold-induced degradation of MdICE1L [60].…”

Background Myelocytomatosis (MYC) transcription factors are crucial mediators of plants responding to environmental stresses through binding DNA regulatory regions. However, little systematic characterization of MYC genes is available in Cucurbitaceae species. Results In this study, we identified 10, 8, 12, and 10 MYC genes separately in Cucumis sativus, Cucumis melo, Citrullus lanatus, and Benincasa hispida. Characterization analysis revealed that all of the MYC proteins contain a highly conserved H4-V5-E6-E8-R9-R11-R12 sequence, which is essential for the binding DNA regulatory regions. The evolutionary analysis enabled us to categorize the predicted 40 MYC proteins from seven species into five distinct groups, which was also discovered that the expansion of the MYC genes occurred before the divergence of monocots and dicots. The upstream promoter region of the MYC genes contain a variety of developmental, stress, and hormone-responsive regulatory elements. The expression of cucumber MYC genes varies significantly across organs, with particularly high expression of CsaV3_3G001710 observed across all organs. Transcriptomic analysis reveals that certain cucumber MYC genes undergo specific upregulation or downregulation in response to both biotic and abiotic stressors. Particularly under temperature stress, cucumber genes CsaV3_3G007980 and CsaV3_3G001710 showed significant upregulation. Interestingly, the homologous genes of these two in C. lanatus exhibited a similar expression pattern to C. sativus, while in B. hispida, they displayed a significant downregulation, which is quite the opposite. These findings indicated that these two genes indeed responded to temperature stress with different expression patterns, highlighting the divergent functions of homologous genes across different species. Conclusions This study analyzed the size and composition of the MYC gene family in four Cucurbitaceae species, and investigated stress-responsive expression profiles, especially under temperature stress. All the results showed that MYC play important roles in development and stress-responsive, laying a theoretical foundation for further investigating its response mechanisms.

“…Several CBFs involved in plant cold resistance have been identified ( Park et al, 2015 ; Jia et al, 2016 ; Wang H. et al, 2021 ; Wang et al, 2021 ). Among these, the ICE - CBFs - COR signaling cascade stands out as a typical cod-resistant pathway, extensively documented in the literature ( Hwarari et al, 2022 ; Kopeć et al, 2022 ; Ma et al, 2023 ; Wang et al, 2023 ). Furthermore, several transcription factors can directly regulate the expression of CBF genes, thereby improving plant cold resistance, such as MdNAC104 , MdHYL1 , MdMYB88 , and MdMYB124 in apples ( Mei et al, 2023 ; Shen et al, 2023 ).…”

Background: Low temperature pose significant challenges to peach cultivation, causing severe damage to peach buds and restricting production and distribution. Ethylene, an important phytohormone, plays a critical role in enhancing plant cold resistance. Structural genes and transcription factors involved in ethylene biosynthesis and signal transduction pathways are associated with cold resistance. However, no research has specifically addressed their roles in peach cold resistance.Methods: In this study, we aimed for cold-resistance gene discovery in cold-sensitive peach cultivar “21Shiji” (21SJ) and cold-resistance cultivar “Shijizhixing” (SJZX) using RNA-seq and gas chromatography.Results: The findings revealed that under cold stress conditions, ethylene biosynthesis in “SJZX” was significantly induced. Subsequently, a structural gene, PpACO1-1, involved in ethylene biosynthesis in peach buds was significantly upregulated and showed a higher correlation with ethylene release rate. To identify potential transcription factors associated with PpACO1-1 expression and ethylene signal transduction, weighted gene co-expression network analysis was conducted using RNA-seq data. Four transcription factors: PpERF2, PpNAC078, PpWRKY65 and PpbHLH112, were identified.Conclusion: These findings provide valuable theoretical insights for investigating the regulatory mechanisms of peach cold resistance and guiding breeding strategies.
