The number of EGTs of each putative origin is given for each species group; for example, for a gene's origin to be predicted as plant and cyanobacteria it must lie in a clade containing species of both these groups. The origins of the genes encoding the enzymes were predicted by using the metaTIGER tree searches (see text). Numbers refer to high-confidence predictions (clades with bootstrap values of 70 or above). Cyanobacteria and Chlamydia are abbreviated to cyano and chlamy, respectively. EGTs of cyanobacterial and plant, or chlamydial and plant origin represent bacterial EGTs into plants that have then been endosymbiotically transferred from plant into their new host - for example, during secondary endosymbiosis.
