RNA structure is critical for multiple steps in gene regulation. However, how the structures of transcripts differ both within and between individual cells is unknown. Here we develop a SHAPE-inspired ...

Growing plant cells assemble a strong yet extensible nanofibrillar structure on their surface, the primary cell wall, which physically limits cell growth and defines cell size and shape. In this ...
