Abstract

The protein Villin is found in both plants and animals across many taxa. In plants, one of the roles of Villin is to aid in root hair formation and function. They do this by assisting in the formation of actin bundles in root hairs in addition to other processes. It has been found that Arabidopsis thaliana with mutated Villin-4 have compromised actin bundles and in certain cases shorter or dysfunctional root hairs. This study examines the effects that the mutation in Villin-4 proteins has on various parts of plant root physiology. By examining the changes in responses of Arabidopsis thaliana Villin-4 mutants to various external abiotic conditions, this study aims to uncover novel phenotypes caused by the mutations in Villin-4. Specifically, this study looks at mutations in the Villin proteins affect the plant’s ability to detect gravity in the presence or absence of salt, in addition to how Villin mutants affect root hair growth and morphology in cold conditions or in a sucrose environment. We hope to elucidate a potential phenotype in gravitropism as expressed in 100mM Nacl through large data collections.
