The role of subgenome expression dominance and DNA methylation in the heterodichogamy of Juglans mandshurica.

Heterodichogamy enhances species diversity and adaptability by reducing inbreeding depression and sexual interference in plants. However, its epigenetic molecular basis remains underexplored. We identified 1877 potential heterodichogamy-related genes (HRGs) in Juglans mandshurica Maxim.

DNA methylation role in subgenome expression dominance of Juglans regia and its wild relative J. mandshurica.

Subgenome expression dominance plays a crucial role in the environmental adaptation of polyploids. However, the epigenetic molecular mechanism underlying this process has not been thoroughly investigated, particularly in perennial woody plants. Persian walnut (Juglans regia) and its wild relative, Manchurian walnut (Juglans mandshurica), are woody plants of great economic importance and are both paleopolyploids that have undergone whole-genome duplication events.

Identification and Characterization of Wall-Associated Kinase (WAK) and WAK-like (WAKL) Gene Family in and Its Wild Related Species .

Wall-associated kinase (WAK) and WAK-like kinase (WAKL) are receptor-like kinases (RLKs), which play important roles in signal transduction between the cell wall and the cytoplasm in plants. have been studied in many plants, but were rarely studied in the important economic walnut tree. In this study, 27 and 14 genes were identified in and its wild related species , respectively.
