The G-signal is a 17 kDa, cell surface-associated protein encoded by the csgA gene [113]. It controls rippling [104], the formation of the symmetric, large aggregates that will develop into mature fruiting bodies [63], and the differentiation of myxospores, which occurs several hours... 

Vitamin C, or ascorbic acid, is important in the formation of collagen, a protein that holds together the connective tissues of skin, muscle, and blood vessels. Vitamin C is obtained from eating citrus fruits. A deficiency of vitamin C causes scurvy, a common disease of sailors in the 1600s who had no access to fresh fruits on long voyages. In Chapter 3, we learn why some vitamins like vitamin A can be stored in the fat cells in the body, whereas others like vitamin C are excreted in urine.
