We compared the DNA variation of one of the predator-avoidance behaviors, the recently extensively studied "death-feigning behavior", between the long strain bred for feigning death for a long time and the short strain bred for feigning death for a short time. To clarify how the difference in DNA sequences between the long and short strains corresponds to the physiological characteristics of the death-feigning duration at the transcriptome level, we performed comprehensive and comparative analyses of gene variants in Tribolium castaneum strains using DNA-resequencing. The duration of death feigning involves many gene pathways, including caffeine metabolism, tyrosine metabolism, tryptophan metaboScientific reportsGenomic characterization between strains selected for death-feigning duration for avoiding attack of a beetle.PMC857594021H02568Sasaki KMiyatake TMatsumura KTanaka KYajima SfalseGenomic characterization between strains selected for death-feigning duration for avoiding attack of a beetle.Predator avoidance is an important behavior that affects the degree of adaptation of organisms.
