The Roles Of Myosin Xi And Rop In Moss Tip Growth, Graham M. Burkart Aug 2014

The Roles Of Myosin Xi And Rop In Moss Tip Growth, Graham M. Burkart

Doctoral Dissertations

Because of the large number of myosin XI and ROP genes found in many angiosperms, it has been difficult to determine their precise role with respect to tip growth. In contrast, there are only two myosin XI genes in four ROP genes in the moss Physcomitrella patens. To determine their role in tip growth using a loss-of-function approach, I used RNA interference (RNAi) and found that both of these proteins are essential for tip growth. Consistent with a role in tip growth, I show that a functional, full-length fusion of mEGFP to myosin XI accumulates at a subcortical, apical region ...
