Web8 Nov 2024 · A review of the first book published on the plant cuticle almost 50 years ago (Martin and Juniper, 1970) stated how neglected the outer layers of epidermal cells had been in the plant biology literature, and expressed hope that the timely book would help in correcting this underestimation. These expectations have been greatly exceeded, and … Web(iv) Desmin, found in myogenic (muscle) cells, (v) GFAP, found in astroglial (brain) cells. Each filament has a central region of more than 300 amino acids. It forms a rod with a- helical organisation. The N-terminal and C-terminal regions differ in the particular type of microfilament. Most of these filaments provide rigidity to cell shape.
