HOW EXCITING IS THAT? In this recent paper in Nature, we show that the stem cells of the apical shoot meristem of plants are embedded in a hypoxic niche; if these cells are exposed to high oxygen, they lose their features as stem cells. This discovery was only made possible by collaboration with the Danish tech company, Unisense. Follow this link to download the paper from Nature’s website.
