摘要

Rice (Oryza sativa L.) is a staple food crop that has sustained human civilizations for millennia, with its origins tracing back to ancient domestication events in Asia. This review explores the remarkable journey of rice, from its humble beginnings as a wild grass to its current status as a globally cultivated crop, and envisions its future driven by genomics in crop breeding. We examine the domestication process that transformed rice into a highly productive cereal shaped by the selection practices of early farmers. The Green Revolution of the twentieth century brought yield increases by developing semi-dwarf, high-yielding varieties and improved crop management practices. However, emerging challenges such as climate change, water scarcity, and the need for sustainable agriculture have necessitated further advancements. The advent of genomics has revolutionized rice breeding, with the complete genome sequence enabling the dissection of key agronomic traits. We discuss how modern techniques like genome sequencing and genome editing are being leveraged to develop climate-resilient, nutrient-enriched, and disease-resistant rice varieties to ensure global food security.
