The dramatic changes in the global climate pose a major threat to the survival of many organisms, including fish. To date, the regulatory mechanisms behind the physiological responses of fish to temperature changes have been studied, and a comprehensive analysis of the regulatory mechanisms of temperature tolerance will help to propose effective strategies for fish to cope with global warming. In this study, we investigated the expression profiles of proteins and metabolites in liver tissues of American shad (Alosa sapidissima) corresponding to different water temperatures (24 °C, 27 °C and 30 °C) at various times (1-month intervals) under natural culture conditions.

BMC Genomics

February 2023

Key Laboratory of Freshwater Fisheries and Germplasm Resources Utilization, Freshwater Fisheries Research Center of Chinese Academy of Fishery Sciences, Ministry of Agriculture and Rural Affairs, Wuxi, Jiangsu, China.

Background: MicroRNAs (miRNAs) are endogenous small non-coding RNAs (21-25 nucleotides) that act as essential components of several biological processes. Golden-back crucian carp (GBCrC, Carassius auratus) is a naturally mutant species of carp that has two distinct body skin color types (golden and greenish-grey), making it an excellent model for research on the genetic basis of pigmentation. Here, we performed small RNA (sRNA) analysis on the two different skin colors via Illumina sequencing.

In vertebrates, the microphthalmia-associated transcription factor (mitf) is at the hub of the melanin synthesis regulation network. However, little information is known about its molecular characterization, expression, location, or function in skin color differentiation and variation of red tilapia. The full-length cDNA sequences (1977 bp and 1999 bp) of mitfa and mitfb, encoding polypeptides of 491 and 514 amino acids, were effectively identified from red tilapia in this study.

The commercial value of red tilapia is hampered by variations in skin color during overwintering. In this study, three types of skin of red tilapia, including the skin remained pink color during and after overwintering (P), the skin changed from pink color to black color during overwintering and remained black color after overwintering (P-B), and the skin changed from pink color to black color during overwintering but recovered to pink color when the temperature rose after overwintering (P-B-P), were used to analyze their molecular mechanisms of color variation. The transcriptome results revealed that the P, P-B, and P-B-P libraries had 43, 42, and 43 million clean reads, respectively.
