Gene expression patterns of candidate genes quantified by qRT-PCR. As a result of the first qRT-PCR, sequences of 23 candidate genes were classified by gene expression patterns. Up-regulated gene candidates were categorized into six groups based on the expression patterns. A: up-regulated during soldier differentiation (2wkPE, PS, or nPS) in both of brain and SOG; B: up-regulated during soldier differentiation in brain and during molt (2wkPE, PS, or nPS, and also SM) in SOG; C: up-regulated during molt in brain and during soldier differentiation in SOG; D: up-regulated during soldier differentiation only in SOG; E: up-regulated during molt in both brain and SOG; F: no specific up-regulation, i.e., false positive.
