Memorization of Abiotic Stimuli in Plants: A Complex Role for Calcium

摘要: Plants are sensitive to various abiotic stimuli (including electromagnetic radiations), which they respond by modifying their development. The response is sometimes delayed, relative the reception of stimulus, implies that corresponding information memorized. A few cases such behavior described, including controlling induction meristems in hypocotyl flax seedlings. Using this model system, calcium has been shown play a key role not only stimulus sensing and possible storage information, but also its final expression. Modifications genome expression, as well posttranslational modifications (e.g., phosphorylation) proteins, involved signal transduction memorization information. SIMS methodology provides us with interesting experimental possibilities. process “ion condensation,” practically ignored biologists so far, may be mechanism. application plant sensitivity agronomical or research problems described. mechanisms elaboration an integrated from plants many, varied receive permanently environment discussed.
