Abstract Details

2003, Master of Science, Miami University, Botany.
Phototropism has been extensively studied in the shoots of plants, however the roots have not been well characterized. Most research has focused on the white and blue light induced negative phototropic response; but recently, a red light induced positive phototropic response was identified in Arabidopsis. In order to determine if this red light induced positive response in roots is common to other species or is specific to Arabidopsis, I characterized root phototropism in Nicotiana sylvestris. The results indicate that Nicotiana does not have a robust phototropic response and is not a good model plant to study root phototropism. Also tested was the hypothesis that gravitropism impaired starchless mutants are a useful for studying root phototropism. However, the starchless mutant of Nicotiana (NS 458) does not appear to be a useful tool for measuring root phototropism as no difference in response between the wild type and the mutant was found.
