Abstract:
:Recent studies have revealed high sequence similarity between homospermidine synthase (HSS), the first pathway-specific enzyme in the biosynthesis of pyrrolizidine alkaloids, a class of sporadically occurring plant defence compounds, and deoxyhypusine synthase (DHS), a ubiquitous enzyme involved in the post-translational activation of the eukaryotic initiation factor 5A (eIF5A). The recruitment of DHS during the evolution of the alkaloid pathway is discussed and interpreted as evolution by change of function.

杂志文章,评审abstract::The treatment of barley aleurone layers with gibberellic acid (GA3) results in the synthesis of two groups of α-amylase isozymes. Addition of abscisic acid (ABA) at the same time as GA3 inhibited the synthesis of both groups of isozymes. However, midcourse ABA addition (12 h or later after GA3) had a more inhibitory e...
