Genome sequencing of the perciform fishLarimichthys croceaprovides insights into stress adaptation

“…Recently, the basic studies on genetic improvement for growth and disease resistance traits of L. crocea are increasingly performed for farming purpose (Ning et al 2007; Mu et al 2010; Liu et al 2013; Ye et al 2014). L. crocea also exhibits peculiar behavioral and physiological characteristics, such as loud sound production, high sensitivity to sound, and well-developed photosensitive and olfactory systems (Su 2004; Zhou et al 2011). Most importantly, L. crocea is especially sensitive to various environmental stresses, such as hypoxia and air exposure.…”

“…Most importantly, L. crocea is especially sensitive to various environmental stresses, such as hypoxia and air exposure. For example, the response of its brain to hypoxia is quick and robust, and a large amount of mucus is secreted from its skin when it is exposed to air (Su 2004; Gu and Xu 2011). These traits may render L. crocea a good model for investigating the response mechanisms to environmental stress.…”

“…L. crocea is a migratory fish with good photosensitivity, olfactory detection, and sound perception, and it contains high levels of selenium (Su 2004). Our genomic analyses provide genetic basis for these behavioral and physiological characteristics.…”

“…L. crocea is named for its ability to generate strong repetitive drumming sounds, especially during reproduction (Su 2004). For good communication, fish have developed high sensitivities to environmental sound.…”

“…Selenium is highly enriched in L. crocea (Su 2004), and it is mainly present as selenoproteins. We used the SelGenAmic-based selenoprotein prediction method (Jiang et al 2010) to analyse the L. crocea genome and identified 40 selenoprotein genes, which is the highest number among all sequenced vertebrates ( Supplemental Table S20 ).…”
