Other claims from this paper (7)
- Observation Ancestral state reconstruction indicated that the abscised calyx was ancestral in angiosperms.
- Observation Most extant angiosperms have persistent calyces with notable variation in size.
- Observation The Solanaceae family may represent a miniature of angiosperm calyx diversity.
- Observation Physalis fruits have a morphological novelty, the inflated calyx syndrome (ICS), unlike Solanum and Capsicum.
- Intervention effect Knockdown and knockout of POS4 and POS5 significantly reduced ICS size in P. floridana.
- Observation Compared with Solanum and Capsicum, heterotopically expressed genes in Physalis calyx relative to berry were mainly enriched for photosynthesis and responses to stimuli.
- Mechanism The inflated fruiting calyx may have partitioned and exapted functions originally associated with berry.
