Herbicides in this mode of action are most effective on annual grasses and some broadleaf weeds. In general, these herbicides are applied preplanting or preemergence and incorporated into the soil. Most herbicides in this mode of action are volatile and need to be incorporated immediately after application to avoid excessive vapor loss. These herbicides are absorbed through both roots and emerging shoots but are translocated only in the xylem. The primary site of absorption and action is the emerging shoot and growing point. Herbicides in this mode of action belong to four chemistries including benzofuranes, chlorocarbonic acids, phosphorodithioates, and thiocarbamates. The specific mode of action of these herbicides is not well elucidated, but there is strong evidence that they interfere with biosynthesis of fatty acids and lipids in the newly developing shoot, which may account for reported reductions in cuticular wax deposition. In addition, these herbicides cause abnormal cell development or prevent cell division in germinating seedlings. They stop the plant from growing by inhibiting cell division in the shoot and root tips while permitting other cell duplication processes to continue.

Plant storage lipids, normally in the form of intracellular triacylglycerol‐rich droplets, are important sources of nutrition for people and livestock; besides, they supply a vast range of renewable industrial products from oleochemicals and bioplastics to paints and biofuels. Storage lipids are mainly found in plant propagules such as seeds and pollen grains, where they form an energy source for post‐germinative growth. The main commercial sources of plant storage lipids are oilseed crops such as soybean, rapeseed and maize or oil‐rich fruits such as olive or oil palm. Triacylglycerols also have several additional nonstorage functions in processes including host–pathogen interactions and abiotic stress responses. Improved knowledge of storage lipid metabolism is being used to create new oil crop varieties and to domesticate new species to supply the ever‐increasing demand for plant oils.

The photosynthetic apparatus in plant ceils is associated with membranes of the thylakoids within the chloroplast and is embedded into a highly specialized lipid matrix. Diacylglycerol galactolipids are common in thylakoid membranes but are excluded from all others. Isolation of the gene DGD1, encoding a galactosyltransferase-like protein, now provides insights into assembly of the thylakoid lipid matrix and subcellular lipid trafficking in Arabidopsis thaliana.

Synthesis of phospholipids and sphingolipids
Glycerol is the starting material in the synthesis of glycerophospholipids. CDP-diacylglycerol is the activated intermediate of this pathway. Sphingolipids are synthesized from palmitoyl CoA and serine, initially to form ceramide. Sphingomyelins and glycolipids are synthesized from ceramide. Various sphingolipids storage diseases are resulted due to hereditary absence of hydrolytic enzymes.
