Biochemistry and genetics of starch synthesis
WebThe site of starch synthesis and storage in cereal grains is the endosperm, and the starch granules are synthesized and located in amyloplasts. Starch content in potato tubers, maize endosperm, sweet potato, and roots of cassava and yam varies between 65% and 90% of the total dry weight. ... * Explores the genetics, biochemistry, and physical ... WebMay 2, 2024 · Starch synthesis occurs primarily in the amyloplast, a potentially iron-rich organelle (Roschzttardtz et al. 2013; Hannah and Boehlein 2024). Thus, maintaining the normal activity of amyloplasts in starchy endosperm cells might require a high level of iron accumulation. ... Biochemistry and genetics of starch synthesis.
