摘要: Abstract This study describes the results from transcriptomes sequenced by illumina technology four populations in marine snail Tegula atra along central-northern Chile (28–31°S) during summer and winter 2014. In silico differential expression of transcripts annotated to known proteins revealed several local patterns associated environmental thermal variability. Herein, northern evidenced lower number genes highly regulated, while southern displayed opposite patterns. relationship could suggest that are more adapted high temperature variations, enabling specific (e.g. HSPs antioxidant system) maintain transcriptional activity under controlled physiological conditions. transcriptome response or “frontloading” strategy can significantly increase speed stress, also be a relevant molecular underpinning explain genomic diversity Chilean coast.
