Abstract

Seedlings of Arabidopsis thaliana were exposed to acoustic stimulation and were observed for changes in root morphology. Seedlings were grown on MS agar plates in an upright position to ease analysis of changes in root morphology. Results show that roots of A. thaliana bend less in response to acoustic stimuli. Compared to the wild-type strain, MSL9 mechanosensor knock-out control and tested groups showed the least root growth and least root bending out of all mutant strains, confirming that the gene which was compromised in MSL9 mechanosensor knock-out is important to root growth and morphology. Root morphological change in response to acoustic stimulus could not be discerned from data gathered from this study.
