    Regulation of three cDNA clones (pT52, pT53, and pT58) was analyzed in terms of wounding alone and wounding in conjunction with developmental and environmental cues (ripening, ethylene, and light) in tomato fruit tissue. The pT52-specific transcript level is induced by

    Ruthenium-catalyzed homo Diels-Alder [2 + 2 + 2] cycloadditions between alkynyl phosphonates and bicyclo[2.2.1]hepta-2,5-diene were studied. The observed reactivity was found to be dependent on the presence of the phosphonate moiety. The Ru-catalyzed cycloaddition was compatible with a variety of

    Perception of the plant hormone ethylene is essential to initiate and advance ripening of climacteric fruits. Since ethylene receptors negatively regulate signaling, the suppression is canceled upon ethylene binding, permitting responses including fruit ripening. Although receptors have autophosphorylation activity, the
