TI  - The Involvement of Glucose in Hydrogen Gas-Medicated Adventitious Rooting in 
      Cucumber.

AB  - Hydrogen gas (H(2)) and glucose (Glc) have been reported as novel antioxidants 
      and signal molecules involved in multiple biological processes in plants. 
      However, the physiological roles and relationships of H(2) and Glc in 
      adventitious rooting are less clear. Here, we showed that the effects of 
      different concentrations Glc (0, 0.01, 0.05, 0.10, 0.50 and 1.00 mM) on 
      adventitious rooting in cucumber were dose-dependent, with a maximal biological 
      response at 0.10 mM. While, the positive roles of hydrogen rich water (HRW, a 
      H(2) donor)-regulated adventitious rooting were blocked by a specific Glc 
      inhibitor glucosamine (GlcN), suggesting that Glc might be responsible for 
      H(2)-regulated adventitious root development. HRW increased glucose, sucrose, 
      starch and total sugar contents. Glucose-6-phosphate (G6P), fructose-6-phosphate 
      (F6P) and glucose-1-phosphate (G1P) contents were also increased by HRW. 
      Meanwhile, the activities of sucrose-related enzymes incorporating sucrose 
      synthase (SS) and sucrose phosphate synthase (SPS) and glucose-related enzymes 
      including hexokinase (HK), pyruvate kinase (PK) and adenosine 5'-diphosphate 
      pyrophosphorylase (AGPase) were increased by HRW. Moreover, HRW upregulated the 
      expression levels of sucrose or glucose metabolism-related genes including 
      CsSuSy1, CsSuSy6, CsHK1, CsHK3, CsUDP1, CsUDP1-like, CsG6P1 and CsG6P1-like. 
      However, these positive roles were all inhibited by GlcN. Together, H(2) might 
      regulate adventitious rooting by promoting glucose metabolism.
