Intramuscular fat (IMF) is a key determinant of beef quality, influencing taste, marbling, and overall flavor. Xinjiang brown cattle (XBC), an indigenous breed from northern Xinjiang, China, presents significant variation in meat quality, with IMF content ranging from 0.2 % to 4.3 % within the population. This variation suggests strong potential for breeding improvement. In this study, we selected 82 XBC for slaughter and meat quality analysis, categorizing them based on IMF content. Using two-dimensional gas chromatography–time-of-flight mass spectrometry (GC×GC-TOF MS), we analyzed volatile flavor compounds across different beef cuts (Longissimus dorsi, Semitendinosus, Supraspinatus). Our results showed that beef with higher IMF levels exhibited enhanced flavor profiles, characterized by sweet, green, fruity, and waxy notes, while castrated bulls displayed the weakest flavor intensity. Metabolomic analysis further revealed significant differences in flavor substances between high and low IMF content beef. RNA-Seq analysis identified key genes (AQP4, FZD2, FADS1, BPG1, CEBPD, FABP4) associated with flavor formation, offering valuable insights for breeding strategies aimed at improving XBC meat quality.

Here, the impact of varying concentrations of NaCl treatments on carotenoid contents in <em>R. odoratus</em> XQR after 120 h of incubation was examined. The results indicated that, as compared to the control (59.37 μg/g_dw), the synthesis of total carotenoids was significantly increased and entirely suppressed under low-to-moderate (0.25 mol/L: 68.06 μg/g_dw, 0.5 mol/L: 67.62 μg/g_dw, and 0.75 mol/L: 146.47 μg/g_dw) and high (1.0, 1.25, and 1.5 mol/L: 0 μg/g_dw) concentrations of NaCl treatments, respectively. Moreover, the maximum production of β-carotene (117.62 μg/g_dw), torulene (21.81 μg/g_dw), and torularhodin (7.04 μg/g_dw) was achieved with a moderate concentration (0.75 mol/L) of NaCl treatment. Transcriptomic and metabolomic analyses suggested that the increase in β-carotene, torulene, and torularhodin production might be primarily attributed to the up-regulation of some key protein-coding genes involved in the terpenoid backbone biosynthesis (<em>atoB</em>, <em>HMGCS</em>, and <em>mvaD</em>), carotenoid biosynthesis (<em>crtYB</em> and <em>crtI</em>), and TCA cycle (<em>pckA</em>, <em>DLAT, pyc, MDH1</em>, <em>gltA</em>, <em>acnA</em>, <em>IDH1/2</em>, <em>IDH3</em>, <em>sucA</em>, <em>sucB</em>, <em>sucD</em>, <em>LSC1</em>, <em>SDHA</em>, and <em>fumA/fumB</em>).

Despite its significance, the major interplay of genetic and epigenetic factors regulating IMF in rabbits remains largely unexplored.

We delve into the potential role of established candidate genes from other livestock (e.g. <em>PPARγ, FABP4,</em> and <em>SCD</em>) in rabbits, while exploring the identified novel genes of IMF in rabbits. Furthermore, we explored the quantitative trait loci studies in rabbit IMF and genomic selection approaches for improving IMF content in rabbits. Beyond genetics, this review unveils the exciting realm of epigenetic mechanisms modulating IMF deposition. We explored the potential of DNA methylation patterns, histone modifications, and non-coding RNA-mediation as fingerprints for selecting rabbits with desirable IMF levels. Additionally, we explored the possibility of manipulating the epigenetic landscape through nutraceuticals interventions to promote favorable IMF depositions. By comprehensively deciphering the genomic and epigenetic terrain of rabbit intramuscular fat regulation, this study aims to assess the existing knowledge regarding the genetic and epigenetic factors that control the deposition of intramuscular fat in rabbits. By doing so, we identified gaps in the current research, and suggested potential areas for further investigation that would enhance the quality of rabbit meat.
