The euAP1 protein MPF3 represses MPF2 to specify floral calyx identity and displays crucial roles in Chinese lantern development in Physalis.
The Chinese lantern phenotype or inflated calyx syndrome (ICS) is a postfloral morphological novelty in Physalis. Its origin is associated with the heterotopic expression of the MADS box gene 2 from Physalis floridana (MPF2) in floral organs, yet the process underlying its identity remains elusive. Here, we show that MPF3, which is expressed specifically in floral tissues, encodes a core eudico...
متن کاملHeterotopic expression of MPF2 is the key to the evolution of the Chinese lantern of Physalis, a morphological novelty in Solanaceae.
Morphological novelties arise through changes in development, but the underlying causes of such changes are largely unknown. In the genus Physalis, sepals resume growth after pollination to encapsulate the mature fruit, forming the "Chinese lantern," a trait also termed inflated-calyx syndrome (ICS). STMADS16, which encodes a MADS-box transcription factor, is expressed only in vegetative tissue...
متن کاملEfficient Gene Silencing Mediated by Tobacco Rattle Virus in an Emerging Model Plant Physalis
The fruit of Physalis has a berry and a novelty called inflated calyx syndrome (ICS, also named the 'Chinese lantern'). Elucidation of the underlying developmental mechanisms of fruit diversity demands an efficient gene functional inference platform. Here, we tested the application of the tobacco rattle virus (TRV)-mediated gene-silencing system in Physalis floridana. First, we characterized th...
متن کاملMPF2-like-a MADS-box genes control the inflated Calyx syndrome in Withania (Solanaceae): roles of Darwinian selection.
The Chinese lantern, which is the inflated calyx syndrome (ICS) of Physalis, is formed by MPF2 in the presence of the plant hormones, cytokinin and gibberellin. MPF2 knockdown mutants of Physalis have small leaves, no ICS, and are male sterile, thus, revealing three MPF2-related functions. Of the close relatives of Physalis, Tubocapsicum has only a rudimentary calyx, whereas others, like the Wi...
متن کاملEvolution of the inflated calyx syndrome in Solanaceae.
Species that express the inflated calyx syndrome (ICS) are found in several genera of the Solanaceae. The MADS-box protein MPF2, together with the plant hormones cytokinin and gibberellin, has been shown to be responsible for this trait in Physalis floridana. We have used sequence data from 114 species belonging to 35 genera to construct a molecular phylogeny of Solanaceae. Apart from the 2 Wit...
