dc.description.abstract | An optimum leaf shape and vein pattern is necessary for vascular plant success. The isolation of leaf morphological mutants of Arabidopsis thaliana has been used for leaf development studies. Auxin is a signal molecular that regulates plant development and growth processes. I have analyzed four mutations in detail, and I suggest that they all have defects in auxin regulated plant development processes. Mutant 115-11-21-4 is an allele of FKD1 with frequent distal free-ending veins. Mutant 31-83-4-3 likely has increased auxin flux through secondary veins and increased downward auxin transport through the shoot, possibly due to increased PIN1 expression and/or altered PIN1 localization. Mutant 32-2-4 likely has increased auxin activity at marginal auxin convergence points resulting in the formation of increased leaf serrations. Mutant 33-7-5(4) may have a global reduction in auxin biosynthesis or response, thus the whole plant is weak and pale, with slower shoot and root growth rate and gravitropic response. | en_US |
