Abstract

During Arabidopsis thaliana seed germination, the weakening of the endosperm cell walls (CWs) is a key step needed to reach germination sensu stricto. Dismantling of these CWs is driven by hydrolytic enzymes such are endo-β-mannanases (MAN; EC. 3.2.1.78) that catalyze the cleavage of the β1 4 bonds in the mannan backbone; this activity increases upon seed imbibition. Transcripts of the most highly expressed AtMAN gene during seed germination (AtMAN7) are restricted to the micropylar endosperm and to the radicle tip just before radicle emergence.
