The Physalis floridana genome provides insights into the biochemical and morphological evolution of Physalis fruits.

ABSTRACT: 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 (~1.40 Gb in size) with a contig N50 of ~4.87 Mb. 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
