Brassica rapa Tall Mutant
Abstract
Brassica rapa is a small flowering plant that is often used in classroom experiments due to its small size, low-maintenance growing conditions, and quick life cycle. Several mutant lines have been bred and briefly described, although not much is known about the actual genetic changes and therefore all the downstream effects of that mutation. Nine different mutant lines of Brassica rapa were grown to more carefully identify the phenotypes affected by the mutations. Tall mutants were grown over 3 weeks and the plant height and the approximate areas of the plant cotyledons were measured.The results of this experiment did not support our hypothesis that the overproduction of Gibberellin causes elongation and larger cotyledons of Brassica rapa. Instead, the data displayed that the cotyledon size of the mutant plants was significantly smaller than that of the wild type.
