Srs5 mutant phenotypes. (A) Seed morphology of T65, Srs5, Srs5/SRS5, d1-1, and d61-2. Bar = 5 mm. (B) Panicle morphology of T65, Srs5, Srs5/SRS5, d1-1, and d61-2. Arrowheads indicate panicle neck nodes. Bar = 10 cm. (C) Gross morphology of T65, Srs5, Srs5/SRS5, d1-1, and d61-2. Bar = 20 cm. (D) Seed length of T65, Srs5, Srs5/SRS5, d1-1, and d61-2. Numbers on graphs indicate average seed length ± S.D. (E) Internode length relative to the total length of the culm. Schematic representation of the internode elongation pattern of T65, Srs5, d1-1, and d61-2. IN: internode.
