Wheat quality and quantity are challenged by increasing global temperature, which poses an urgent need for heat tolerance breeding in wheat. The identification of seedling-stage factors highly associated with reproductive-stage performance can enable early-stage selection enhance the efficiency effectiveness breeding. This study investigated myeloblastosis (MYB) gene family, one largest transcription factor (TF) families plants, its response to seedling- stress Genome-wide analysis MYB TF genes identified 876 TaMYB genes, 48 were selected qRT-PCR expression based on silico under abiotic stresses. Correlation quantitative real-time polymerase chain reaction (qRT-PCR) pattern a heat-tolerant genotype (Perenjori) two heat-sensitive genotypes (Brazil32 Yitpi) at seedling stage grain-filling five (TaMYB-327, TaMYB-049, TaMYB-030, TaMYB-226, TaMYB-023) four (TaMYB-232, TaMYB-343, TaMYB-305, TaMYB399) sensitivity As important stress-responsive these showed similar patterns between early late developmental stages, indicating existence correlation therefore providing theoretical basis

Background: Coptis chinensis is a traditional medicinal plant rich in bioactive compounds like berberine, known for its antibacterial, anti-inflammatory, and antioxidant properties. This study aims to analyze the MYB transcription factor family C. better understand their roles growth, development, metabolism, stress responses. Methods: We employed bioinformatics conduct genome-wide identification of genes chinensis, followed by analyses physicochemical properties, phylogenetic relationships, gene structures, chromosomal localization, conserved motifs, cis-acting elements, expression patterns. Results were validated using qRT-PCR. Results: A total 129 CcMYB identified across nine chromosomes. Phylogenetic analysis categorized these into 19 subgroups, notably highlighting S6 subgroup, which lacks counterparts Arabidopsis. Comparative genomics revealed segmental duplication among pairs. Transcriptomic indicated that CcMYB21, CcMYB40, CcMYB105, CcMYB116 had high levels stems. Importantly, CcMYB94 significantly increased under cadmium stress, suggesting role regulation. Conclusions: offers comprehensive underscoring significance factors enhancing plant’s value tolerance, particularly against exposure. These insights pave way further exploration specific improve resilience chinensis.
