Fine-tuning phosphatidic acid production for optimal plant stress responses.

ABSTRACT

Phosphatidic acid (PA) is involved in biotic and abiotic stress responses in plants. Here, we summarize quantitative lipidomics and real-time imaging used in PA studies and highlight recent studies of diacylglycerol (DAG) kinase (DGK) 5, an enzyme involved in PA biosynthesis, facilitating fine-tuning PA production for optimal stress responses in plants.
