Characterisation of cytochrome c oxidase-coding genes from mung bean and their response to cadmium stress based on genome-wide identification and transcriptome analysis.

Background: Cytochrome c oxidase (COX) is a crucial mitochondrial enzyme in the electron transport chain of plants, implicated in energy production and stress responses. Despite its importance, the function of COX in leguminous plants, especially under heavy metal stress like cadmium (Cd), remains understudied.

Methods And Results: In this study, COX genes (COX s) were identified based on the genome annotation file in mung bean (Vigna radiata (Linn.
