Drought stress frequently occurs during the rapid fruit expansion and maturation stages, and AQPs might mediate its drought response. However, the diversity, molecular characteristics and biological functions of\n                    <jats:italic>AQPs<\/jats:italic>\n                    in\n                    <jats:italic>C. oleifera<\/jats:italic>\n                    remain largely uncharacterized. Here, 166\n                    <jats:italic>CoAQPs<\/jats:italic>\n                    were identified and classified into five subfamilies based on phylogenetic analysis. They were mainly localized to the plasma membrane and vacuole. Members within the same subfamily shared conserved gene structures and motif compositions. Segmental duplication was the main driving force for\n                    <jats:italic>CoAQPs<\/jats:italic>\n                    expansion. The promoter region of\n                    <jats:italic>CoAQPs<\/jats:italic>\n                    contained abundant cis-acting elements associated with light response, phytohormone response, stress response, and plant growth and development. Tissue-specific expression analysis revealed that 50\n                    <jats:italic>CoAQPs<\/jats:italic>\n                    were highly expressed in leaves, whereas 27\n                    <jats:italic>CoAQPs<\/jats:italic>\n                    showed differential expression in developing seeds. Drought stress induced significant physiological and biochemical responses in leaves and fruits of\n                    <jats:italic>C. oleifera<\/jats:italic>\n                    .
