Fig. 4From: Genome-wide identification of MST, SUT and SWEET family sugar transporters in root parasitic angiosperms and analysis of their expression during host parasitismMaximum likelihood tree of the three clades of SUT genes from parasitic plant transcriptomes and non-parasitic Mimulus genome. Note the increase in SUT1 expression during stage 6–2 and the heightened expression in Triphysaria during germination in the SUT4 cladeBack to article page
