Live confocal imaging of petal conical cells in Arabidopsis thaliana
Floral petals of nearly 79% of angiosperm species contain conical epidermal cells that are thought to influence light capture and reflectance, and provide pollinator grips, but the mechanisms controlling conical cell morphogenesis are poorly understood. Using a live confocal imaging approach, we show that in Arabidopsis thaliana, the spatio-temporal organization of microtubule arrays plays crucial roles in controlling conical cell morphogenesis. The image shows well-ordered microtubule arrays in conical cells expressing GFP-Tubulin6, and the side visualization of conical cells from the propidium iodide-stained petals. See Ren, Dang et al.
