Superoxide Dismutase: A POSSIBLE PROTECTIVE ENZYME AGAINST OZONE INJURY IN SNAP BEANS (PHASEOLUS VULGARIS L.).

abstract：:Physalis spp. develop the "Chinese lantern" trait, also known as inflated calyx syndrome, that is a morphological novelty. Here, we identified the double-layered-lantern1 (doll1) mutant, a recessive and monofactorial mutation, in Physalis floridana; its corolla and androecium were transformed into the calyx and gynoec...
