Introduction The Loxechinus albus (Molina, 1782), or edible red sea urchin, is definitely an echinoderm species in the Chilean and Peruvian coasts, distributed along ca. Cape Horn, Chile (56 70 S) towards the Isla Lobos de Afuera, Peru (6 53 S) [1]. The worldwide demand for high-quality gonads of this sea urchin has addressed a vast overexploitation of its natural populations [2]. Harvesting of L. albus represents the main sea urchin fishery among world urchin fisheries [3].Biology 2021, 10, 995. https://doi.org/10.3390/biologyhttps://www.mdpi.com/journal/biologyBiology 2021, ten,2 ofThe aquaculture of this species, involving the rearing tank production of larvae, juvenile, and later fattening in natural environments, are critical approaches to aquaculture diversification in Chile and to restore the overexploited coastal locations [4]. One of many primary troubles in the study of biological and molecular mechanisms linked together with the farming of this species may be the limited genomic data obtainable [5,6]. In this context, transcriptome sequencing is beneficial to recognize genes participating particular biological processes when genomic data are not accessible [7]. This evaluation makes it possible for a broad comprehension of molecular mechanisms involved in biological processes from data on predicted function of genes [8]. Progress within the characterization of the transcriptome in industrial sea urchins is achievable due to advances in next-generation sequencing (NGS) technologies. NGS has allowed the analysis of sea urchin transcriptomes as well as other non-model species in brief periods of time at a low cost [91]. The molecular data accomplished has offered considerable worth regarding the physiological responses to adaptation within a variety of commercial sea urchins below fluctuating environmental situations [12,13]. At this time, the current information on L. albus biology is restricted and is related to with oxidative metabolism [14], development patterns [15], the performance of early juveniles beneath meals type and feeding frequency [16], and cryopreservation of embryos and larvae [17]. Nonetheless, biological studies with molecular bases carried out within this species are scarce, primarily as a result of low level of genomic facts obtainable [11,18]. Even though some advances happen to be made within the transcriptome characterization and mitogenome of this species in recent years, the low coverage on the technologies applied, too as the use of gonads because the only target tissue, has limited the obtainment of a high-quality reference transcriptome [5,six,9,19]. Thus, we present right here the initial annotated transcriptome of juvenile edible red sea urchin working with NGS technologies primarily based on 3 critical tissues for physiological homeostasis of echinoderms along with the expression evaluation in the transcripts present in ea.
