A multidisciplinary research team, led by the CSIC biologist at CRAG, Ana I. Caño Delgado, and the physicist from the University of Barcelona, Marta Ibañes, has discovered that two plant stem cell proteins, known for their role in the correct development of the root, physically interact and regulate each other to avoid cellular division. The study, result of fifteen years of continued research carried out by the two researchers, reveals that these two proteins, known as BRAVO and WOX5, act in a specific manner in a small group of stem cells, and that their interaction is key to the plant’s survival under genomic and environmental stress factors like extreme cold, heat, or floods. The results, obtained with the model plant Arabidopsis thaliana, have recently been published in Molecular Systems Biology.
