Synthesis of cell wall
WebSome progresses in understanding the synthesis and deposition of cellulose are briefly summarized. A focus is especially placed on the way AGPs might participate in cellulose synthesis and deposition during cell wall biogenesis, and as a result, five hypothetical models of AGP action are proposed.
