Jianhong Hu is a plant researcher credited as first author of a 2018 study connecting auxin and gibberellin signalling during tomato fruit initiation. The paper lists a Department of Biology affiliation at Duke University.
Hu and colleagues combined protein-protein interaction assays with single and double mutants. They found interactions between DELLA repressors and auxin-response regulators, and additive effects on parthenocarpy. The combination of biochemical interaction and whole-plant phenotypes linked molecular signalling to whether an unfertilized ovary begins growing into a fruit.[ref]
