Special Issue Information

Dear Colleagues,

Genetic diversity forms the basis for plant adaptation to abiotic stresses. This diversity provides plants with the ability to dynamically adjust their physiological and biochemical processes in response to a wide range of environmental stresses. Under stress conditions, plants initiate a series of gene expressions and produce specific proteins to combat the negative effects of the external environment. These gene regulatory processes involve complex signal transduction pathways. Simultaneously, plants possess the ability to influence gene expression and functionality through the regulation of gene mutations. This capability impacts plant physiology, morphology, and molecular adaptability, empowering them to effectively contend with particular environmental stresses like drought, high temperatures, and salinity. These adaptive mutations are retained by natural selection during the evolution of plant populations and gradually accumulate, thereby improving the adaptability of the entire population.

This Special Issue aims to bring together the latest research results and perspectives on the genetic adaptation of plants to abiotic stresses. We welcome articles including original research papers, perspectives, opinions, and reviews that thoroughly explore the role of genetic diversity, gene mutation, gene regulation, and natural selection in plant adaptation to abiotic stresses. By delving into these fields through extensive research, we anticipate achieving a deeper comprehension of how plants adapt to diverse environmental conditions. This understanding can offer valuable insights into enhancing agricultural production and promoting ecological conservation.

Bananas are one of the most important cash crops in the tropics and subtropics. Drought and low-temperature stress affect the growth of banana. The DREB (dehydration responsive element binding protein) gene family, as one of the major transcription factor families, plays crucial roles in defense against abiotic stress. Currently, systematic analyses of the banana DREB (MaDREB) gene family have not yet been reported. In this study, 103 members of the MaDREB gene family were identified in the banana genome. In addition, transcriptomic analysis results revealed that MaDREBs responded to drought and cold stress. The expression of MaDREB14/22/51 was induced by drought and cold stress; these geneswere selected for further analysis. The qRT-PCR validation results confirmed the transcriptome results. Additionally, transgenic Arabidopsis plants overexpressing MaDREB14/22/51 exhibited enhanced resistance to drought and cold stress by reducing MDA content and increasing PRO and soluble sugar content. This study enhances our understanding of the function of the MaDREB gene family, provides new insights into their regulatory role under abiotic stress, and lays a good foundation for improving drought and cold stress-tolerant banana verities.
