Abstract: Previously, we found (2Z,4E)-5-phenylpenta-2,4-dienoic acid (ku-76) to be a selective inhibitor of root gravitropic bending of lettuce radicles at 5 μM, with no concomitant growth inhibition, and revealed the structure-activity relationship in this inhibitory activity. The… read more here.

DOI: 10.1104/pp.18.00126
Abstract: Endogenous free para-aminobenzoic acid levels modulate the auxin-ethylene crosstalk necessary for root gravitropism Plants respond to gravitational force through directional growth along the gravity vector. Although auxin is the central component of the root graviresponse,… read more here.

DOI: 10.3390/ijms23168965
Abstract: The distribution and content of auxin within plant tissues affect a variety of important growth and developmental processes. Polar auxin transport (PAT), mainly mediated by auxin influx and efflux transporters, plays a vital role in… read more here.
