In VitroPlant StudyHighlightedH2 supplied via ammonia borane stimulates lateral root branching via phytomelatonin signalingMHID-7645260PMID: 379440262023Plant PhysiologyYueqiao Wang, Shanshan Jin, Ziyu Liu, Genmei Chen, Pengfei Cheng, Longna Li, et al.A reliable and stable hydrogen gas (H2) supply will benefit agricultural laboratory and field trials. Here, we assessed ammonia borane (AB), an efficient hydrogen storage material used in the energy industry, and determined its effect on plant physiology and the corresponding mechanism. Through hydroponics and pot experiments, we discovered that AB increases tomato (Solanum lycopersicum) lateral r
