DOI: 10.1002/etc.3833
Abstract: Impacts of polyvinylpyrrolidine-coated silver nanoparticles (AgNPs) on root gravitropism in Arabidopsis thaliana were investigated at the physiological, cellular, and molecular levels. Our results showed that AgNPs were taken up by the root and primarily localized… read more here.

DOI: 10.1073/pnas.2212199119
Abstract: Significance Plants use the Earth’s gravitational field to orient their growth, but there are large gaps in our understanding of the mechanism. We measured thousands of corn seedling roots, changing their growth direction in response… read more here.

DOI: 10.1093/plphys/kiae134
Abstract: Root angle is a critical factor in optimising the acquisition of essential resources from different soil depths. The regulation of root angle relies on the auxin-mediated root gravitropism machinery. While the influence of ethylene on… read more here.

DOI: 10.3390/plants13091189
Abstract: Cell expansion in a discrete region called the elongation zone drives root elongation. Analyzing time lapse images can quantify the expansion in kinematic terms as if it were fluid flow. We used horizontal microscopes to… read more here.
