Plant Aquaporins: Genome-Wide Identification, Transcriptomics, Proteomics, and Advanced Analytical Tools

Area of Science:

• Plant biology
• Molecular biology
• Biochemistry

Background:

• Aquaporins (AQPs) are integral membrane proteins crucial for water and solute transport in plants, with plant genomes encoding a significantly larger number of AQPs compared to animals.
• Genome-wide characterization of plant AQPs reveals insights into their distribution, genetic organization, evolution, and conserved features dictating solute specificity.

Approach:

• Leverages homology-based identification due to conserved protein sequences across plant species.
• Integrates transcriptomics and proteomics data with advanced computational tools for analyzing large omic-scale datasets.
• Utilizes experimental techniques like Xenopus oocyte assays, yeast expression systems, and proteoliposomes to study AQP transport mechanisms.

Key Points:

• Computational advancements enable sophisticated prediction of AQP tertiary structures, pore architecture, and molecular interactions.
• Understanding AQP function relies on integrating computational predictions with experimental data on physiological properties, kinetics, and phylogeny.
• Omics resources and computational pipelines are essential for efficient AQP research.

Conclusions:

• This review synthesizes current knowledge on genome-wide AQP identification in plants, emphasizing the synergy between computational and experimental approaches.
• It provides a comprehensive catalog of computational tools and analytical pipelines to aid researchers in plant aquaporin studies.
• The review aims to optimize the utilization of available omics resources for advancing aquaporin research.
