WebNov 15, 2010 · However, rice ferritins are probably more involved with oxidative stress protection than with iron storage in the grain (Stein et al., 2009b), similar to Arabidopsis, where no more than 5% of total seed Fe is stored in ferritin (Ravet et al., 2009). Webgrains are transparent in nature and can be classified as simple or compound starch grains. Starch grain is formed in amyloplast, a double-membrane bound organelle that is involved in starch synthesis and storage [9]. Compound starch granules are assembled by smaller starch granules into 10 20 µm particles [10,11].
