- The sex-linked barring of chicken feather pattern is a fascinating trait, and it has great application value in chicken breeding by enabling autosexing. In this study, the transcriptome changes in skin follicle tissues from the back (SKs) and crown of the head (SKHs) were explored by RNA-seq in Wenshang Barred chickens during their feather pattern formation. The key genes and signaling pathways regulating sex-linked barring formation in chickens were analyzed. As a result, a total of 2291 and 4496 differentially expressed genes (DEGs) were found in SKs and SKHs, respectively, during barred feather formation. The expression pattern clusters of Profile 6 and Profile 7 were the important and mainstream expression trends of the DEGs. Melanogenesis KEGG pathway and GO terms of melanocyte differentiation, melanosome organization and melanin biosynthetic biological processes were significantly enriched in the DEGs, including the well-known TYR, TYRP1, EDNRB and PMEL genes, clustered in Profile 6 expression pattern. A series of DEGs, including CDKN2A, SFN, CDKN2B and CDK1, were significantly enriched in the cell cycle pathway and were mostly clustered in Profile 7. Protein‒protein interaction (PPI) network analysis revealed TYR, TYRP1, CDKN2A and SFN were the hub genes. It was speculated that CDKN2A may target SFN to regulate the melanocyte cycle arrest, causing the formation of white bands of sex-linked barring. TYR, TYRP1, EDNRB and PMEL genes may play important regulatory roles by melanogenesis pathway in the early growth of black feathers, as well as in the later formation of black stripes. The different expression patterns of SLC45A2, KIT, MC1R, ASIP, DCT and SOX10 in SKs and SKHs may contribute to the different formation processes of barred feather patterns on the head and the back. These results provide new insights into the regulation of sex-linked barred feather patterns in Chinese native chicken and provide a valuable theoretical foundation for future chicken breeding and related efforts. - 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
