Breakdown of the plant protein benchmark dataset derived from Swiss-Prot database (release 55.3) according to the procedures described in the Materials section.

None of proteins included here has sequence identity to any other in a same subcellular location.
aThe benchmark dataset here covers 12 plant subcellular locations and the “Golgi apparatus” is newly added in comparison with the dataset in [13] that covered 11 location sites.
bSee Eqs.2–3 for the definition about the number of locative proteins, and its relation with the number of different proteins.
cOf the 978 different proteins, 904 have one subcellular location, 71 have two locations, 3 have three locations, and none have four or more locations.
