Adventitious Cucumbers?

Hydrogen-rich water regulates cucumber adventitious root development


Hydrogen gas (H2) is an endogenous gaseous molecule in plants. Although its reputation is as a “biologically inert gas”, recent results suggested that H2has therapeutic antioxidant properties in animals and plays fundamental roles in plant responses to environmental stresses. However, whether H2 regulates root morphological patterns is largely unknown. In this report, hydrogen-rich water (HRW) was used to characterize H2 physiological roles and possible signaling transduction pathways in the promotion of adventitious root (AR) formation in cucumber explants.
