Besides regulating meristem formation and maintenance in vivo, SHOOTMERISTEMLESS ( STM ) has been shown to affect embryogenesis. While the over-expression of Brassica napus (Bn)STM enhances the number of microspore-derived embryos produced in culture and their ability to regenerate viable plants,...
An indeterminate developmental program allows plant organs to grow continuously by maintaining functional meristems over time. The molecular mechanisms involved in the maintenance of the root apical meristem are not completely understood. We have identified a new Arabidopsis thaliana mutant named...
We modified gibberellin (GA) metabolism and signaling in transgenic poplars using dominant transgenes and studied their effects for 3 years under field conditions. The transgenes that we employed either reduced the bioactive GAs, or attenuated their signaling. The majority of transgenic trees had...
Proteomics facilitates our understanding of cellular processes and network functions in the plant defense response during abiotic and biotic stresses. Here, we demonstrate that the ectopic expression of the Capsicum annuum antimicrobial protein CaAMP1 gene in Arabidopsis thaliana confers enhanced...
