Auxin is the phytohormone responsible for many aspects of plant growth and development, such as apical dominance and tropisms, but the underlying auxin transport mechanisms remain poorly understood.

The signaling molecule auxin plays a fundamental role in plant development. Gene expression responses to auxin mediate most patterning processes 1 but also underlie differential growth in response to ...

Embryos have two distinct ends, which become apparent early on. Quite how this initial polarity is sustained in plant embryos has been unclear. Step forward the agent provocateur of plant development ...
