The Involvement of Callose and Elicitors in Ethylene Production Caused by Mechanical Perturbation

摘要: When plants are mechanically perturbed (MP) by wind, rubbing, flexing or other means, they undergo thigmomorphogenesis (10). This reaction, which is ubiquitous, usually consists of a retardation elongation the stem coupled with thickening (10), Both terrestrial and aquatic subject to perturbation fluid flow: The former wind latter currents water (25). It probable that arose in response flow environment. In earlier papers (10,13,14), I have proposed thigmomorphogenetic hypothesis: namely mild moderate MP causes be more resistant rupture due subsequent severe MP, Thus, if stand trees sheltered from perimeter trees, cut down, will susceptible (falling) first strong occurs (9), hypothesis now has enough experimental support called “Thigmomorphogenetic Theory” (17,22). present paper describe some these data, together what known hormonal mechanism thigmomorphogenesis.
