In this paper we show that Cuscuta can parry the changes in host cell wall composition that it triggered during its infection and that different host species are met with different strategies of gene expression fine-tuning. The same can be triggered by offering isolated cell wall polysaccharides in a host-free system (without a live host present), strengthening the conclusion that Cuscuta uses chemical cues from its environment to maximise the chance of infection success.
