Strigolactone synthesis is ancestral in land plants, but canonical strigolactone signalling is a flowering plant innovation

Loglikelihood (logL) per topology, as well as p value for weighted KH test (p-WKH); p value for weighted SH test (p-WSH) and p value for the Approximately Unbiased test (p-AU) as calculated in IQ-tree. Highlighted in grey are the non-rejected hypotheses. See the ‘Materials and methods’ section for further details
