Extended Data Figure 1: SWEET9 molecular phylogenetic analysis using the neighbour-joining method.
From: Nectar secretion requires sucrose phosphate synthases and the sugar transporter SWEET9
A phylogenetic tree of SWEET proteins collected from different species: A. thaliana (At), Manihot esculenta (Me), Solanum lycopersicum (Sl), P. trichocarpa (Pt), M. truncatula (Mt), Glycine max (Gm), Oryza sativa (Os), Amborella trichopoda (Ambo), Aqulegia caerulea (Ac), Physcomitrella patens (Pp) and Chlamydomonas reinhardtii (Cr). Accessions are listed in Supplementary Table 6. The SWEET9 orthologue cluster (blue) is part of clade 3 and was completed with SWEET9 collected also from B. rapa (Br), Petunia hybrida (Ph), N. attenuata (Na), Theobroma cacao (Tc), Fragaria vesca (Fv), Ricinus communis (Rc), Malus domestica (Md) and Carica papaya (Cp). Bootstrap values are out of 1,000 replicates.
