英文摘要: In plants, trehalose-6-phosphate (Tre6P) synthesized by the Tre6P synthase (TPS) acts as a signal metabolite in regulating sucrose metabolism in relation to plant growth and development. The Hevea genome predicts a total of 14 TPS genes, and two class I TPS members, HbTPS1 and 2 , were explored here for their expressions under various hormone and abiotic stress treatments. HbTPS1 and 2 expressions in latex, cytoplasm of rubber-producing laticifers, were markedly affected by the treatments of ethephon (2-chloroethylphosphonic acid, an ethylene releaser), 2,4-dichlorophenoxyacetic acid, jasmonic acid and salicylic acid although in a distinct manner. HbTPS1 and 2 expressions were significantly up-regulated in a similar manner by cold (5 °C) and heat (40 °C) as examined in Hevea seedling...
