In the channel catfish (Ictalurus punctatus), 16 HSP70 genes were detected via a combination of genome databases and RNA-seq data, and 9 and 2 gene family members showed significant expression in gill tissue after a challenge with the Flavobacterium columnare and in intestine tissue after infection with the Edwardsiella ictaluri [14]. The gene discussed is HSPA1A; the disease is infection.
