Special Issue Information

Dear Colleagues,

Woody plants are crucial resources for human life and economic development. Their important characteristics, such as flowering phenology, fruit type, wood density, oil content, and secondary metabolites, directly affect their production and utilization. The formation of the important traits of woody plants is influenced by various factors, including genes, environment, and gene–environment interaction. Although the molecular mechanism of the formation of many important traits is still unclear, some scholars have studied the phenotypic observation, genetic analysis, gene expression, and functional identification of different tree species, revealing the role of related genes or gene families in their formation. Some systems or platforms suitable for genetic transformation or the editing of forest trees have been established, which provide tools to further verify the functions of related genes in the formation of important characteristics. However, research on the genetic improvement and regulation of woody plants’ important characteristics is limited compared to other model plants. Therefore, this Special Issue aims to provide an overview of the research and identification of important characteristics of woody plants, as well as the physiological and molecular mechanisms regulating these traits. Specifically, this issue seeks research contributions on the formation of the unique characteristics of different woody plant organs, including leaves, flowers, and fruits, as well as on the formation of traits such as wood density, oil content, secondary metabolites, and other substance enrichment.

Potential topics include, but are not limited to:

  • The physiological regulation mechanism of the formation of important characteristics in woody plants;
  • Mining genes related to the formation of important traits in trees;
  • Study on the function of genes related to the formation of important characteristics in woody plants;
  • Regulatory network for the formation of the important characteristics of woody plants;
  • Prospect of research on the formation of the important characteristics of woody plants.

The walnut (Juglans regia) is a nut with a high nutritional value and has been recognized throughout the world as an economically important woody plant. However, the walnut is vulnerable to abiotic stresses, especially low-temperature freezes, which can severely impede their growth and development, resulting in substantial financial losses. The CBF (C-repeat binding factor) gene, a unique plant transcription factor classified within the AP2/ERF (ethylene response factor) family, plays a vital role in the process of plants coping with abiotic stress, particularly low temperatures. This study utilized bioinformatics techniques to identify eight JrCBF genes within the walnut genome, distributed across six chromosomes. The upstream promoter sequences of these genes are rich in cis-regulatory elements related to hormonal responses and non-biotic stresses. Transcriptome data and qRT-PCR analysis revealed that JrCBF1 and JrCBF2 were significantly upregulated under low temperatures. JrCBF1 and JrCBF2 also responded positively to high-temperature stress. Under drought stress, JrCBF5 and JrCBF8 had a significant difference in their expression relative to other genes. To gain further insights into their functionality, subcellular localization experiments were conducted on JrCBF1 and JrCBF2, confirming their nuclear localization. These results provide valuable insights into the specific functions of CBF gene in enhancing the resistance of walnut to abiotic stress. Full article
