    Phosphate deficiency response and membrane lipid remodeling in plants
    (Springer Nature Publishing AG, 2021) Verma, Lokesh; Rumi; Sinha, Alok Krishna; Giri, Jitender
    Phosphorus (P) deficiency represents one of the significant constraints affecting plants growth and development. Plants have evolved with various adaptations to maximise the uptake of soil P and its distribution in the different organs. Membrane phospholipids store a significant amount of P as the cellular resource that is remobilised under the P deficiency condition. To utilise this P resource, plants initiate membrane lipid remodeling in which metabolic pathways are activated to allow Pi extraction from the phospholipids and reduce the P demand by increasing the synthesis of P-free lipids for replacing the phospholipids in the membrane. Many organisms, including non-photosynthetic/photosynthetic bacterium to plants employ this adaptation to survive under P deficiency conditions. The candidate genes and encoded enzymes seem to be broadly conserved among the different organisms; however, there are variations in a spatiotemporal manner. Here, we discuss the molecular mechanisms of membrane lipid remodelling and its regulation crucial for plants adaption to Pi deficiency.
