Seed and fiber morphology in GhTM-1, Gb3–79, and GhMD17. a Fiber morphologies on mature cotton seeds before (top) and after (bottom) lint fiber removal show both lint and fuzz fibers in G. hirsutum TM-1 (GhTM-1), lint finer in G. barbadense 3–79 (Gb3–79), and no fiber in GhMD17. b Paraffin embedded tissue of the ovule at 0 or 2 day post anthesis (DPA) in GhTM-1, Gb3–79, and GhMD17. Scale bars = 100 μm. c Lint fiber length (μm) in the ovules at 0 or 2 DPA in GhTM-1 (light gray) and Gb3–79 (black). Fiber length in a given stage was similar between GhTM-1 and Gb3–79 (Student t-test). d Diagram of epidermis (outer integument) for tissue collection using laser-capture microdissection (LCM) from the ovules at 0 or 2 DPA in GhTM-1, Gb3–79, and GhMD17. Colors indicate epidermal cell (blue), fiber cell (red), and underlying epidermal cell (gray). Dissected regions of epidermal cells (blue) and fiber cells (red) are indicated by rectangle boxes
