Recent Advances in Plant Aquaporins

Aquaporins are important functional proteins in plants, which not only transport water between different plant tissues but also participate in other nutrient transmembrane movement. Aquaporins also play a significant role in many physiological processes such as photosynthesis, plant growth and development, immune response, and signal transduction. We reviewed recent research progress on the structural features, classification, and physiological functions, as well as transcriptional and post-transcriptional regulation of aquaporins, and provided good study prospects on the processes plant AQPs take part in for plant growth. Detailed research on aquaporins could contribute to a better understanding of the physiological functions and molecular mechanisms of nutrient movement in plants, thus providing a theoretical base for growth and development regulation in crop production.
