Plant immunity: Crosstalk between plant immune receptors

Plant immunity has long been divided into two 'tiers', involving cell-surface versus intracellular immune receptors. Although both systems can induce similar diagnostic responses, they have been considered independent pathways. Recent work challenges this view, showing a striking requirement for both recognition layers to achieve maximum immune output.

Automated summary

Plant immunity has traditionally been divided into two tiers, but recent research shows that both cell-surface and intracellular immune receptors are needed for maximum immune response.
