PIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_9G213920 (symbol PIP, also known as BvPIP, PIP2-6, BvPIP1, PIP1) on sugar beet chromosome 9 encodes an aquaporin-like protein with channel and water channel activity. It is associated with water transport, response to salt, cold, and osmotic stress, ABA signaling, pH reduction, protein folding and heterotetramerization, lipid and carbohydrate metabolism, and cell division. The gene is linked to photosynthetic rate, salt tolerance, water stress response, and plant growth. It localizes to the membrane and plasmalemma. Studies of related genes in other species link the family to traits including drought tolerance, water use efficiency, leaf water potential, net photosynthetic rate, transpiration rate, stomatal resistance, chlorophyll content, root length, plant height, fruit size, germination rate, and defense and viral resistance.
