"A long-distance inhibitory system regulates haustoria numbers in parasitic plants", our work is now out in @PNASNews . We propose that parasitic plants count their infection numbers, and dynamically regulate new infections in response. Read all about it: pnas.org/doi/abs/10.1073/pna…

The ability of parasitic plants to withdraw nutrients from their hosts depends on the formation of an infective structure known as the haustorium. ...
