One significant challenge is the underutilization of high-throughput technologies like whole-genome sequencing and genome-wide association studies (GWAS) due to the lack of a well-annotated and assembled reference genome for buffaloes (Rehman et al., 2021). Additionally, while microsatellite markers have been used to assess genetic diversity, they often show limited polymorphism and may not provide comprehensive insights into genetic variation (Uffo et al., 2017; Ünal et al., 2021). The existing SNP panels, primarily developed for cattle, are not fully applicable to buffalo, necessitating the development of buffalo-specific SNP chips (Iamartino et al., 2017). These limitations hinder the full exploration of genetic diversity and the potential for genomic selection in buffalo breeding programs. 7.2 Bridging the gap between research and practical applications To bridge the gap between research and practical applications, it is crucial to translate molecular findings into actionable breeding strategies. This involves integrating molecular data with traditional breeding practices to enhance traits such as milk production, disease resistance, and climate resilience (Debaky et al., 2019). The development of buffalo-specific genomic tools, such as the 90K SNP chip, provides a foundation for genome-assisted selection programs, which can be used to improve economically important traits (Iamartino et al., 2017). Furthermore, fostering collaborations between researchers and breeders can facilitate the implementation of molecular breeding techniques in practical settings, ensuring that scientific advancements lead to tangible improvements in buffalo productivity and conservation (Du et al., 2019). 7.3 Emerging technologies and their potential for advancing genetic studies Emerging technologies hold significant promise for advancing genetic studies in water buffalo. Techniques such as ddRAD sequencing and the development of trait-specific SNPs offer new avenues for identifying genetic markers associated with key traits like milk volume and feed conversion efficiency (Mishra et al., 2020). These technologies enable more precise genetic mapping and the identification of candidate genes for marker-assisted selection (Du et al., 2019). Additionally, the use of ISSR-PCR markers has been shown to effectively assess genetic diversity and structure, providing valuable insights for conservation genetics (Mokhnachova, 2022). As these technologies continue to evolve, they will enhance our understanding of buffalo genetics and support the development of more efficient and sustainable breeding programs. In summary, addressing the limitations of current molecular approaches, bridging the gap between research and practical applications, and leveraging emerging technologies are critical steps toward advancing the genetic study and conservation of water buffalo. These efforts will contribute to the sustainable management and improvement of buffalo populations worldwide. 8 Concluding Remarks The studies on molecular markers and genetic variation in water buffalo have revealed significant insights into the genetic diversity and structure of various buffalo populations. For instance, the evaluation of Turkish water buffalo populations using microsatellite markers demonstrated a clear genetic diversity, indicating the presence of at least two major clusters. Similarly, the analysis of Cuban water buffalo breeds using microsatellite markers highlighted the genetic variability within the population, which is crucial for conservation and breeding strategies. In Pakistan, the identification of breed-specific SNP markers has provided a deeper understanding of the genetic makeup of buffalo breeds, emphasizing the need for conservation programs. Additionally, the development of a 90K SNP genotyping assay has facilitated genomic analyses, aiding in genetic selection and diversity studies. The findings from these studies have significant implications for conservation and breeding programs. The genetic diversity observed in Turkish and Cuban buffalo populations suggests the potential for developing targeted conservation strategies to preserve genetic resources. The identification of SNP markers in Pakistani buffalo breeds underscores the importance of genomic characterization in designing effective breeding programs to
