What's a GeneRIF?
  1. synthesis of a water-insoluble, partly crystalline, amylose-containing starch-like polyglucan restored in GlgB-expressing transgenic plants
    Title: Expression of Escherichia coli glycogen branching enzyme in an Arabidopsis mutant devoid of endogenous starch branching enzymes induces the synthesis of starch-like polyglucans.
  2. There was the suggestion in the data that impairments of starvation, cold and desiccation resistance were worse for the strain lacking glgB, though the first of these was not statistically significant.
