Summary: Plants face a more volatile environment due to their immobility, prompting the development of efficient mechanisms to adapt to stress. MYB transcription factors, a widespread family in plants, play critical roles in plant development and responses to stresses. Multiple studies have shown that MYB proteins are involved in diverse roles in responses to abiotic stresses, but their regulatory mechanism is still not well understood.

Summary: In this study, novel MYB transcription factors were identified across the genomes of four crops, leading to an updated eudicot MYB phylogeny and new insights into the sequence variation in the C-terminus of anthocyanin-activating MYBs. Experimental results highlighted the presence of new short linear motifs within subgroup 6, which may play a role in protein-protein interaction.

Summary: MYB transcription factors are DNA binding proteins involved in plant growth, secondary metabolism, stress response, and hormone signal transduction. In this study, 182 MYB transcription factors were identified from the Casuarina equisetifolia genome, divided into different subgroups based on phylogenetic analysis and gene structure. Analysis of conserved motifs and gene structures revealed similar characteristics among CeqMYB members, with specific amino acid residues present in the R2 and R3 domains. 32 MYB genes were further studied for their response to salt stress, showing differential regulation under different salt treatments. Seven genes were identified to be involved in salt stress response, with CeqMYB4 potentially playing a key role in this process.

Summary: Scutellaria baicalensis is a medicinal plant that contains flavones with various health benefits. Light exposure induces the production of flavones and activates the expression of biosynthesis genes. Two MYB transcription factors, SbMYB45 and SbMYB86.1, were identified in S. baicalensis and found to enhance the transcription of the flavone biosynthesis gene SbCHI. Overexpression of SbMYB45 and SbMYB86.1 increased the accumulation of flavones in S. baicalensis leaves.

Summary: This study conducted a comprehensive analysis of VcMYBs in blueberry under drought stress, revealing 229 non-redundant MYB sequences in the blueberry genome divided into 23 subgroups. A total of 102 MYB DEGs were identified with significant responses to drought stress, showing potential key VcMYB genes involved in ROS pathway and leaf regulation under drought treatment.

Summary: This study systematically analyzed the MYB gene family in tobacco and identified 246 transcription factors. These factors were divided into 33 subgroups and 44 gene pairs were found to be duplicated. The potential functions of these genes were predicted using phylogenetic, synthetic, and expression analysis. NtMYB102 was found to be induced by drought and salt stress, and its overexpression enhanced the tolerance of transgenic tobacco to these stressors.

Summary: Large and increasing areas of salt-affected soils are causing difficulties for agriculture. To address the challenges, understanding the molecular mechanisms behind salt stress responses and tolerance is crucial for developing salt-tolerant varieties. The MYB family of transcription factors play a significant role in responses to salt stress. Through genome analysis, 719 putative MYB proteins were identified in Chinese spring wheat, with the most common protein combination being MYB_DNA-binding and MYB-DNA-bind_6 domains. Four MYB transcription factors (MYB3, MYB4, MYB13, and MYB59) were found to be involved in salt stress responses, as confirmed by qPCR analysis. These MYBs regulate nine target genes that are associated with cellular and metabolic processes.

Summary: This study discovered that the transcription factor VaERF16 enhances grape resistance to B. cinerea infection and the bacteria Pseudomonas syringae DC3000. VaERF16 interacts with VaMYB306 transcription factor, leading to an up-regulation of the defense-related gene PDF1.2 and increased resistance. Elucidation of this regulatory module is of importance in enhancing grapevine resistance to B. cinerea infection.

Summary: The function of the root system is crucial for plant survival, and MYB genes have been identified as key regulators in root development and adaptive responses. MYB genes from the same subfamily regulate similar biological processes in roots through redundant but precise ways. Understanding the functions of MYB genes in roots can provide insights into root regulatory mechanisms and contribute to a more inclusive green revolution and sustainable agriculture.

Summary: The transcriptional regulation of HvCslF6, the main gene contributing to (1,3;1,4)-beta-glucan biosynthesis in barley grain, was investigated. In-silico analysis of the putative promoter revealed over-representation of TF classes AP2/ERF, MYB, and bHLH. Functional characterization using a barley protoplast transient expression system identified HvMYB61 and HvMYB46/83 as putative activators of HvCslF6 expression.

Summary: This study systematically analyzed MYB genes in four cotton species and revealed the mechanisms of MYB gene family expansion and their conservation. The study further demonstrated the important roles of MYBs in response to drought and salt stress and confirmed their positive effects on drought tolerance through experiments. These findings not only expand our understanding of the evolution and function of MYB genes but also provide potential candidate genes for cotton breeding.

Summary: Auxin, as a crucial plant hormone, induces the biosynthesis of secondary metabolites in ornamental plant Hedychium coronarium. By identifying and characterizing the transcription factors HcMYB1 and HcMYB2, it was found that they play essential roles in regulating the formation of floral scent compounds in response to auxin signaling, by interacting with key genes and proteins involved in the process.
