Local auxin competition explains fragmented differentiation patterns

Local auxin competition explains fragmented differentiation patterns

Sieve element differentiation in Arabidopsis roots requires two antagonistic regulators of auxin efflux, BRX and PAX. Here the authors show that together they coordinate sieve element formation by preventing cell fate bistability emerging from AUX1-mediated competition for auxin between neighboring...
