Table 6 Species indicators of species assignation strategy which are adapted from Wang et al. [8]

Identifier

The gene is assigned a species when the gene is extracted by gene identifier extraction.

A bar for Cat8 is not included, as only one gene (YOR019W, factor change 2.1) has a Cat8 site alone.

Prefix

The first lowercase letter of the gene name is an abbreviation of its species.

h ZIP 2 (human gene)

Previous indicator

The tax_id is assigned to a gene entity if the species entity appears in front of the gene entity.

Drosophila HCF

zebraflsh Ltk

Forward indicator

The tax_id is assigned to a gene entity if the species entity is in front of the gene entity in the same sentence. The nearest species is used for assignment.

Conversely, ISWI is a unique and essential gene in Drosophila, highlighting a possible divergent role for ISWI in flies and a distinct mechanism of interaction with the Sin3A/Rpd3 complex in higher eukaryotes.

Backward indicator

The tax_id is assigned to a gene entity if the species entity precedes the gene entity in the same sentence. The nearest species is used for assignment.

We identify the shady gene as encoding a cell signaling receptor, leukocyte tyrosine kinase (Ltk), that has recently been associated with human auto-immune disease.

Majority indicator

The most frequently mentioned tax_id is assigned to the gene entity if it cannot be assigned by previous rules.

The most frequent mention of PMCID: 2880583 is tax_id is 9606 (Human) as shown in Table 7.
