With the rapid development of human society and economy, factors such as climate change have prompted the sharp loss of global biodiversity. Plants are a core component of biodiversity, and ex situ conservation to save endangered plants has become the core work of botanical gardens. At present, ex situ conservation based on protecting the genetic diversity of endangered plants remains a challenge. Genomic technologies have made it possible to accurately identify the taxonomic status of endangered plants, explore the population evolutionary dynamics and endangering causes of endangered plants and analyze genetic diversity at the whole-genome level and its adaptability to future climates. This paper summarizes the development of genomic sequencing technologies for plant conservation and the effectiveness and current status of ex situ conservation, as well as the research progress of genomics in helping protect endangered plants in terms of mining functional and adaptive variant genes, species identification, genetic risk assessment, and regulation of growth, development, and secondary metabolism. In response to how to promote future ex situ conservation in the genomic era, countermeasures, suggestions, and future development trends are proposed.
