火龙果（pitahaya或dragon fruit）属于仙人掌科（Cactaceae）的火龙果属（Hylocereus或Selenicereus），因其有益健康的特性而闻名于世界各地，特别是在热带和亚热带地区。虽然人们对火龙果的品质性状进行了广泛的研究，但对火龙果果实品质性状形成的分子机制的研究却很少。火龙果的世代周期、多倍体、高杂合性和复杂的生理结构等因素使其育种改良成为一项复杂的工作。此外，缺乏有效的方法和资源加剧了加强这种水果作物育种的挑战。近年来，生物技术和测序技术的进步在支持和加快传统育种技术方面发挥了至关重要的作用，并为火龙果的分子机制和进化过程提供了见解。本文综述了火龙果研究的最新进展，包括基因组、转录组、代谢组和蛋白质组测序，功能基因鉴定和调控网络分析，以及该领域出现的新工具、平台和程序。为进一步研究火龙果果实性状的基因功能和分子育种奠定了基础，有助于加快火龙果育种进程。
Pitaya (pitahaya or dragon fruit) belongs to the genusHylocereusorSelenicereusin the Cactaceae family, and is well-known all over the world, especially in tropical and subtropical regions, for its health-benefiting properties. Although the pitaya traits have been extensively studied, only few studies focus on the molecular mechanisms underlying the formation of fruit quality traits in pitaya. The breeding improvement of pitaya is a complex task due to various factors, including its generation cycle, polyploidy, high heterozygosity, and complex physiological structure. Furthermore, the absence of effective methods and resources exacerbates the challenges in enhancing the breeding of this fruit crop. In recent years, advancements in biotechnology and sequencing technologies have played a vital role in supporting and expediting conventional breeding techniques, as well as providing insights into the molecular mechanisms and evolutionary processes of pitaya. This review puts a spotlight on an overview of the latest developments in pitaya research, including genome, transcriptome, metabolome, and proteome sequencing, functional gene identification and regulatory network analysis, as well as the novel tools, platforms, and programs that have emerged in this field. It paves the way for studying the gene functions and molecular breeding with desirable fruit traits of pitaya, which will help accelerate pitaya breeding progress.
