Plant storage compounds such as starch and lipids are important for human and animal nutrition as well as industry. There is interest in diverting some of the carbon stored in starch-rich organs (leaves, tubers, and cereal grains) into lipids in order to improve the energy density or nutritional properties of crops as well as providing new sources of feedstocks for food and manufacturing. Previously, we generated transgenic potato plants that accumulate up to 3.

The mode of action of artocarpin was evaluated by its effect on cell viability, nuclear morphology, cell cycle progression, expression of protein markers for apoptosis, and mitochondrial membrane potential (Delta psi m). These results showed that artocarpin caused a reduction of cell viability in a concentration-dependent manner and an alteration of cell and nuclear morphology.

As studies in the flowering plant Arabidopsis have suggested synthesis of the (1,4)-beta-glucan backbone of xyloglucan (XyG), a wall polysaccharide that tethers adjacent cellulose microfibrils to each other, as a probable function for the CSLCs, CSLC function was investigated in barley (Hordeum vulgare L.), a species with low amounts of XyG in its walls.
