Genome-Wide Survey Indicates Diverse Physiological Roles of Dendrobium officinale Calcium-Dependent Protein Kinase Genes.

ABSTRACT: Calcium-dependent protein kinases (CDPKs) are crucial calcium ions (Ca²⁺) sensors in plants with important roles in signal transduction, plant growth, development, and stress responses. Here, we identified 24 genes encoding CDPKs in Dendrobium officinale using genome-wide analysis. The phylogenetic analysis revealed that these genes formed four groups, with similar structures in the same group. The gene expression patterns following hormone treatments and yeast two-hybrid of homologous CDPK gene pairs with Rbohs showed differences, indicating functional divergence between homologous genes. In addition, the rapid accumulation of hydrogen peroxide (H₂O₂) and stomatal closure was observed in response to salicylic acid (SA)/jasmonic
