- Red tilapia has gained increasing popularity worldwide in the commercial aquaculture production due to its rapid growth and delightful taste. However, the occurrence of skin colour variation poses a significant challenge to the advancement of commercial culture. Furthermore, the molecular regulatory mechanism and genetic basis for the distinct skin colouration in red tilapia remain undisclosed. In this study, a comprehensive transcriptome analysis was conducted on red tilapia with different skin colour by integrating PacBio Iso-seq technology with Illumina short-read sequencing methods. A total of 41.38 Gb of clean data was generated, resulting in the acquisition of 30,970 transcripts. Among them, 10,829 transcripts were successfully annotated in at least one public database. In addition, 10,827 coding sequences, 452 transcription factors, and 781 lncRNAs were identified in new transcripts. Furthermore, we performed RNA-seq analysis to identify skin colour-associated genes in red tilapia with three colour spots (white spots, W; black spots, B; red spots, R). The results revealed the identification of 278 differentially expressed genes (DEGs) between the comparison groups, which included B vs R, B vs W, and WvsR.Amongthem, some known genes were found to be involved in regulating the skin pigment synthesis, including PMEL, Wnt-4, melanoregulin and ALK in red tilapia with different skin colour. In addition, some pathways, including melanogenesis (ko04916), ECM receptor interaction (ko04512), Hedgehog signaling pathway (ko04340) and steroid hormone biosynthesis (ko00140), were associated with the skin pigment synthesis in red tilapia. Furthermore, the quantitative real-time PCR analysis confirmed a moderate correlation (coefficient of 0.68) between the results obtained from the qPCR and RNA-seq methodologies. In summary, our findings will significantly contribute to the enhanced comprehension of the molecular regulatory mechanisms underlying the variation in skin colour observed in red tilapia.. - Source: PubMed

Lapkina EkaterinaRuksha Tatiana - Animal colouration is a key trait in organismal biology, being involved in natural and sexual selection, competition, and communication. Amphibians use their highly diverse colouration in many ecological interactions, but the molecular bases of their colour variation are less well understood than in other vertebrate systems. While the genetic, structural, and cellular bases of pigmentation are increasingly understood in a range of models, potential epigenetic or epitranscriptomic effects are almost completely unexplored. The fire salamander (Salamandra salamandra) has striking colour patterns and polymorphisms, but the extremely large genome size of salamanders makes traditional genetic analyses infeasible. To discover loci and molecular mechanisms underlying colour differences in salamanders, we used long-read direct RNA sequencing to test the roles of RNA methylation, gene expression and their relationship on intra- and inter-individual colour variation in black, yellow and brown skinned salamanders. We found 129 differentially expressed and 281 differentially methylated genes across all pairwise comparisons. Many of the genes involved are related to pigmentation, with several directly associated with melanin production, such as Melan-A (MLANA), Premelanosome protein (PMEL), Tyrosinase (TYR) and Tyrosinase-related protein 1 (TYRP1). We found both a positive overall correlation and a significant overlap in transcripts that are differentially methylated and expressed. These findings suggest multiple molecular mechanisms, including gene expression and RNA methylation, contribute to amphibian colour diversity. RNA modifications as a promising area for understanding morphological variation in non-model animals and their impact on their ecology. - Source: PubMed
Strowbridge NicholasVieites David RRitchie Michael GElmer Kathryn R - Mitochondria form contact sites with multiple organelles to coordinate diverse cellular processes. Melanosomes, lysosome-related organelles, undergo stepwise maturation to synthesize and store melanin, but how they interact with mitochondria remains unclear. Here we show that mitochondria-melanosome contacts dynamically increase during melanosome maturation and are mediated by STIM1-MFN2 interactions. Using a NanoBiT-based reporter system, MiMSBiT (Mitochondria-Melanosome contact reporter applying NanoBiT), to monitor reversible mitochondria-melanosome contacts in living cells, we demonstrate that STIM1 localizes to melanosomes and promotes their contact with mitochondrial MFN2. A transient decrease in melanosomal lumen calcium induces STIM1 clustering and enhances its association with MFN2. These contacts locally increase mitochondrial ATP availability, leading to melanosome lumen acidification via proton channel activation. This acidification facilitates PMEL fibrillation, a key step in melanosome maturation. Together, our findings reveal a mechanism by which mitochondria-melanosome contacts regulate melanosome maturation. - Source: PubMed
