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. Non-purple hairless seeds were grown over six weeks and plant stem color was recorded. After three days of germinating non-purple hairless seeds, root hair formation was measured. In conclusion, the non-purple hairless mutant showed little to no purple color in their stems and significantly less lateral root hair growth.
