Distinct modulations of the hexokinase1-mediated glucose response and hexokinase1-independent processes by HYS1/CPR5 in Arabidopsis. Aki T, Konishi M, Kikuchi T, Fujimori T, Yoneyama T, Yanagisawa S. J Exp Bot. 2007;58(12):3239-48. ...... By contrast, additional hys1 phenotypes, including an increase in salicylic acid (SA), production of abnormal trichomes, and early senescence, were not suppressed by the loss of HXK1. Surprisingly, the hxk1 and hys1 mutations acted synergistically towards an increased SA accumulation. Hence, HYS1/CPR5 appears to be a versatile protein that modulates both the HXK1-mediated glucose response and various HXK1-indepndent processes that are ...... |
