^mManual Annotation.

^bSupported by BlastP (E<3×10⁻³²).

^cSupported by conserved domains identified through Pfam.

^zCombined with another protein making fold change imprecise.

Protein names are based on UniProtKB unless otherwise stated and Protein IDs are from the Joint Genome Institute T. pseudonana genome version 3 (http://genome.jgi-psf.org/Thaps3/Thaps3.home.html).
