摘要： Drought is a significant environmental limiting factor that restricts the growth of Quercus wutaishanica Mayr. The MYB transcription factor plays a wide role in controlling the growth of plants. In this study, the QwMYB108 gene was cloned and the bioinformatics was analyzed, and we examined how QwMYB108 responded to various gradient drought stresses. The results demonstrated that QwMYB108 encoded 275 amino acids using an 828 bp open reading frame. Subcellular localization indicated that the gene was located in the nucleus. Phylogenetic analysis showed that QwMYB108 was close to Q. robur, and that the highest level of expression was found in leaves, which was significantly different from other tissues. The expression of QwMYB108 increased as the stress degree rose when drought stress was present, and there was a significant difference between severe drought stress and other gradient stress. In this study, the function of QwMYB108 in drought stress response was investigated, and the drought response function gene of Q. wutaishanica was further explored to provide a theoretical basis.
