Kalanchoe fedtschenkoi cultivar:M2 Genome sequencing and assembly. Kalanchoe fedtschenkoi cultivar:M2

Crassulacean acid metabolism (CAM) is a water-use efficient adaptation of photosynthesis that has evolved independently many times in diverse lineages of flowering plants. Kalanchoe fedtschenkoi, an obligate CAM species, is a model species for research into the molecular biology and functional genomics of CAM due to its relatively small genome, low repetitive sequence content, and efficient stable transformation protocols. This genome sequence renders K. fedtschenkoi as a new model for plant evolutionary and comparative genomics research, both for CAM photosynthesis and beyond.

景天酸代谢（Crassulacean acid metabolism）是一类在多样开花植物谱系中多次独立进化形成的、可提升水分利用效率的光合作用适应性策略。费氏伽蓝菜（Kalanchoe fedtschenkoi）作为专性CAM物种，因其基因组规模相对较小、重复序列含量低且拥有高效稳定的遗传转化体系，成为CAM分子生物学与功能基因组学研究的模式物种。该基因组序列的解析，使费氏伽蓝菜成为植物进化与比较基因组学研究的新型模式物种，其适用范畴不仅涵盖CAM光合作用研究，还可延伸至其他植物学研究领域。
