13. Temporal and spatial regulation of 1-aminocyclopropane-1-carboxylate oxidase in the pollination-induced senescence of orchid flowers.
Pollination of many flowers initiates a sequence of precisely regulated developmental events that include senescence of the perianth and development of the ovary. The plant hormone ethylene is known to play a key role in regulating the biochemical and anatomical changes that constitute the postpollination syndrome. For this reason, we have studied the pollin

16. Dynamic 1-Aminocyclopropane-1-Carboxylate-Synthase and -Oxidase Transcript Accumulation Patterns during Pollen Tube Growth in Tobacco Styles1
In flowering plants, pollination of the stigma sets off a cascade of responses in the distal flower organs. Ethylene and its biosynthetic precursor 1-aminocyclopropane-1-carboxylate (ACC) play an important role in regulating these responses. Because exogenous application of ethylene or ACC does not invoke the full postpollination syndrome, the pollination si

17. Floral and ecological isolation between Aquilegia formosa and Aquilegia pubescens.
Habitat preference and pollination syndrome have been suggested as major factors in reproductive isolation among plant species. The columbine genus Aquilegia contains species that have been used as classic examples of reproductive isolation due to ecological and floral factors. In this analysis Aquilegia formosa, Aquilegia pubescens, and natural hybrid popul

18. Heterotopic 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).
