PfPAH1-1 gene enhances plant tolerance to low phosphate stress by modulating cell membrane lipid remodeling.

Phosphate (Pi) is an essential macroelement for plant survival, and Pi deficiency triggers membrane lipid remodeling that promotes the conversion of phospholipids to galactolipids. Perilla frutescens is a traditional food and medicinal plant, widely used in food, pharmaceutical, and industrial sectors. Importantly, Perilla seed oil is rich in polyunsaturated fatty acids (PUFAs) and are considered an ideal source of healthy vegetables oils for humans.
