Putative algal genes identified in Ciona intestinalis
Gene familya Putative donor Putative function
Short-chain dehydrogenase/reductase family (7) Green algae/ cyanobacteria Cellular differentiation and signaling
Solute carrier family 23 (7) Algae/land plants Na+-dependent vitamin C transport
Taurine dioxygenase (1) Green algae Cell redox homeostasis
Cytidine monophospho-N-acetylneuraminic acid synthetase (1) Algae Signaling regulation
Arginine N-methyltransferase 7 (1) Land plants/ stramenopiles Protein methylation
Peptidylglycine alpha-hydroxylating monooxygenase (1) Green algae Hormone biosynthesis
Aminoglycoside phosphotransferase (1) Algae Protein amino acid phosphorylation
Solute carrier family 22 (27) Algae/land plants Ion transport
Solute carrier family 34 (6) Diatoms Phosphate ion transport
Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 2 (3) Stramenopiles Potassium ion transport
UDP galactopyranose mutase (2)* Algae Uridine diphosphogalactofuranose biosynthesis
Biphenyl/valacyclovir hydrolase (3) Dinoflagellates/haptophytes Aromatic compound metabolism
Solute carrier family 6 (31) Algae Neurotransmitter transport
Alkylation repair homolog 5 (1) Algae/land plants Alkylation repair

aNumbers in the brackets show paralogous gene copies within each family. *The gene transfer event happened only between algae and C. intestinalis. All other gene transfers happened between plastid-containing organisms and the ancestral animal.
