Sericulture in India is a highly remunerative industry, especially for the rural population. Mulberry is an extremely versatile plant, having multifaceted applications, the most important being the sole feed for the monophagus silkworm, Bombyx mori. Profitability of the sericulture industry is directly correlated with production of high-quality mulberry leaves. However, mulberry productivity is severely impacted by abiotic as well as biotic stresses. Therefore, to develop stress-tolerant mulberry with desired characteristics, a comprehensive understanding and utility of biotechnological resources is essential. Research efforts on mulberry encompass broad range of fields in plant biology from breeding, molecular markers, transcriptomics, proteomics, and metabolomics. Additionally, a large number of mulberry germplasm accessions have been maintained and evaluated in several countries. Identification of superior cultivars under stressed regimes is extremely important, and therefore, physiological traits have often been used as proxy genetic markers for assessing stress tolerance index. Mulberry genomic resources have provided a limited but an important list of novel candidate genes, thus enhancing the scope for future investigations for improvement of its productivity. The present review article gives a bird's eye view of current initiatives of genomics advancements in mulberry research and enumerates the prospects for enhancing its productivity.
印度的养蚕业是一个高利润的行业，特别是对农村人口而言。桑树是一种非常多用途的植物，具有多方面的应用，最重要的是唯一的饲料对单食性蚕，家蚕。养蚕业的盈利能力与高质量桑叶的产量直接相关。然而，桑树的生产力受到非生物和生物胁迫的严重影响。因此，为了开发具有所需特性的耐胁迫桑树，必须全面了解和利用生物技术资源。桑树的研究工作涵盖了植物生物学的广泛领域，包括育种、分子标记、转录组学、蛋白质组学和代谢组学。此外，许多桑树种质资源已在多个国家得到保存和评估。在胁迫条件下鉴定优良品种非常重要，因此，生理特性通常被用作评估耐胁迫指数的替代遗传标记。桑树基因组资源提供了一个有限但重要的新候选基因列表，从而为提高其生产力的未来研究提供了更多的机会。本文综述了桑树研究中基因组学进展的最新举措，并列举了提高其生产力的前景。
