The fruits of Physalis(Solanaceae)have a unique structure,a lantern-like fruiting calyx known as inflated calyx syndrome(ICS)or the Chinese lantern,and are rich in steroid-related compounds.However,the genetic variations underlying the origin of these characteristic traits and diversity in Physalis remain largely unknown.Here,we present a high-quality chromosome-level reference genome assembly of Physalis floridana(~1.40Gb in size)with a contig N50 of~4.87Mb.Through evolutionary genomics and experimental approaches,we found that the loss of the SEP-like MADS-box gene MBP21 subclade is likely a key mutation that,together with the previously revealed mutation affecting floral MPF2 expression,might have contributed to the origination of ICS in Physaleae,suggesting that the origination of a morphological novelty may have resulted from an evolutionary scenario in which one mutation compensated for another deleterious mutation.Moreover,the significant expansion of squalene epoxidase genes is potentially associated with the natural variation of steroid-related compounds in Physalis fruits.The results reveal the importance of gene gains(duplication)and/or subsequent losses as genetic bases of the evolution of distinct fruit traits,and the data serve as a valuable resource for the evolutionary genetics and breeding of solanaceous crops. 展开更多
