Regeneration traits –such as germination strategies, seed dormancy, and seedling establishment– are presumably shaped by environmental variables that operate at different temporal and spatial scales. However, empirical evidence about the variation is lacking for most regeneration seed traits. Here,…

Review. Roles of plant retinoblastoma protein: cell cycle and beyond The cell cycle is at the heart of processes such as cell division, fate acquisition and cell cycle exit towards differentiation. Decades of cell cycle research in animals and yeast have outlined the main components that control the…

When we cut out cookies from rolled-out dough, we often end up with unwanted dough scraps, and sometimes the dough sticks to the cookie-cutter, resulting in misshapen cookies. Just like these misshapen cookies, faulty or aberrant RNAs can arise in cells due to mistakes during transcription, RNA processing,…

From the flat white sheets of our favourite weed Arabidopsis thaliana to the colourful cups and spirals of orchids, petals come in a spectacular array of shapes, sizes, colours and textures. These elaborate forms have often evolved to attract pollinators. For example, bee orchids produce petals that…
