Abstract
The antagonistic bacterium Pseudomonas protegens secretes the cyclic lipopeptide orfamide A, which triggers a Ca2+ signal, causing the deflagellation of the green microalga Chlamydomonas reinhardtii. By investigating targeted synthetic orfamide A variants and inhibitors, we found that at least two Ca2+-signalling pathways and TRP channels are involved in this response.
