Abstract

Potato is the most widely grown non-grain crop and ranks as the third most significant global food crop following rice and wheat. Despite its long history of cultivation over vast areas, slow breeding progress and environmental stress have led to a scarcity of high-yielding potato varieties. Enhancing the quality and yield of potato tubers remains the ultimate objective of potato breeding. However, conventional breeding has faced challenges due to tetrasomic inheritance, high genomic heterozygosity, and inbreeding depression. Recent advancements in molecular biology and functional genomic studies of potato have provided valuable insights into the regulatory network of physiological processes and facilitated trait improvement. In this review, we present a summary of identified factors and genes governing potato growth and development, along with progress in potato genomics and the adoption of new breeding technologies for improvement. Additionally, we explore the opportunities and challenges in potato improvement, offering insights into future avenues for potato research.

马铃薯：从功能基因组学到遗传改良。

马铃薯是种植面积最广的非谷类作物，是继水稻和小麦之后全球第三大粮食作物。尽管马铃薯在广大地区的种植历史悠久，但育种进展缓慢和环境压力导致高产马铃薯品种稀缺。提高马铃薯块茎的质量和产量仍然是马铃薯育种的最终目标。然而，由于四体遗传、高基因组杂合度和近亲繁殖抑制，传统育种面临着挑战。马铃薯分子生物学和功能基因组研究的最新进展为了解生理过程的调控网络提供了宝贵的见解，并促进了性状的改良。在本综述中，我们概述了已确定的调控马铃薯生长和发育的因子和基因，以及马铃薯基因组学的进展和采用新育种技术进行改良的情况。此外，我们还探讨了马铃薯改良的机遇和挑战，为马铃薯研究的未来途径提供了见解。

期刊介绍： Aims Molecular Horticulture aims to publish research and review articles that significantly advance our knowledge in understanding how the horticultural crops or their parts operate mechanistically. Articles should have profound impacts not only in terms of high citation number or the like, but more importantly on the direction of the horticultural research field. Scope Molecular Horticulture publishes original Research Articles, Letters, and Reviews on novel discoveries on the following, but not limited to, aspects of horticultural plants (including medicinal plants): ▪ Developmental and evolutionary biology ▪ Physiology, biochemistry and cell biology ▪ Plant-microbe and plant-environment interactions ▪ Genetics and epigenetics ▪ Molecular breeding and biotechnology ▪ Secondary metabolism and synthetic biology ▪ Multi-omics dealing with data sets of genome, transcriptome, proteome, metabolome, epigenome and/or microbiome. The journal also welcomes research articles using model plants that reveal mechanisms and/or principles readily applicable to horticultural plants, translational research articles involving application of basic knowledge (including those of model plants) to the horticultural crops, novel Methods and Resources of broad interest. In addition, the journal publishes Editorial, News and View, and Commentary and Perspective on current, significant events and topics in global horticultural fields with international interests.
