PROTEIN KINASES THAT REGULATE ROOT WAVING
Laboratory of John C. Watson
Dept. of Biology, Indiana University-Purdue University Indianapolis,
A postdoctoral position is available immediately to study how root
waving in Arabidopsis is regulated by two protein kinases called WAG1
and WAG2. Experiments with knockout mutants in the WAG1 and WAG2
genes showed that neither single mutant exhibits a discernable
phenotype in most analyses. However, wag1/wag2 double mutants exhibit
a pronounced phenotype in seedlings grown on vertical agar plates:
the roots have a wavy pattern observed in wild type only on plates
inclined at pitches less than 90 degrees. The wag1 and wag2 single
mutants exhibit less pronounced root waving on vertical plates. To
elucidate the roles of WAG1 and WAG2 as negative regulators of root
waving, we aim to: (1) Ask whether the altering expression or kinase
activity of WAG1 and WAG2 affects the root waving response in
transgenic Arabidopsis seedlings; and (2) Explore the underlying
mechanisms for the wavy root phenotype in wag1/wag2 mutants,
particularly with regard to gravitropism and the transport of and
response to auxin. A strong background in the molecular biology,
genetics, and physiology of Arabidopsis is necessary.
