Phenotypic characterization of the <i>sd37</i> mutant.

<p>(A) Gross morphology of the <i>sd37</i> mutant and 3037 (wild type) plants at 7 DAG. Bar = 1 cm. (B) Heading stage of the <i>sd37</i> mutant and 3037 plants. Bar = 10 cm. (C) Internode lengths of the <i>sd37</i> mutant and 3037 plants at the mature stage. P, panicle; I, first internode below panicle; II, second internode below panicle; III, third internode below panicle; and IV, fourth internode below panicle. Bar = 1 cm. (D) Panicle morphology of the sd<i>37</i> mutant and 3037. Bar = 2 cm. (E) Grain morphology. The <i>sd37</i> mutant plants have shorter and broader grains than 3037 plants. Bar = 5 mm (seeds). (F) Graph showing the root lengths of <i>sd37</i> and 3037 plants during the first 14 days of development. Data are averages of 20 plants (± SD).
