Abstract:
The shoot organs of plants are built through the activity of stem cell centers, called shoot apical meristems (SAM). The level of SAM activity affects shoot architecture and thus yield in crop plants. This work focused on the molecular mechanisms by which the peptidase AMP1 affects SAM activity in Arabidopsis. The results demonstrate that AMP1 controls SAM structure by limiting the activity of HD-ZIPIII proteins, which consequently constrain the expression of the ERF transcription factor RAP2.6L.

Pflanzen bilden Sprossorgane mithilfe von Stammzellen, die in Sprossmeristemen (SM) organisiert sind. Die Aktivität des SM beeinflusst die Sprossarchitektur und damit auch die Produktivität von Nutzpflanzen. Das Ziel dieser Arbeit war die molekulare Funktion der Peptidase AMP1 in der Regulation der SM-Aktivität zu charakterisieren. Die Ergebnisse demonstrieren, dass AMP1 die Bildungsrate von HD-ZIPIII Proteinen als auch die Transkription des ERF Transkriptionsfaktors RAP2.6L kontrolliert.
