  2. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    A kinetic and regional chemical study of the Evelyn effect has been described. The results, in the Journal of Chemical Education, made claims involving the mechanism by which the dehydrations occurred. The article looks into the claim of having E1 and E2 mechanisms occur in the reaction.

  3. Dehydrin - Wikipedia

    en.wikipedia.org/wiki/Dehydrin

    One chemical mechanism related to DHN production is the presence of the phytohormone ABA. One common response to environmental stresses is the process known as cellular dehydration. Cellular dehydration induces biosynthesis of abscisic acid ( ABA ), which is known to react as a stress hormone because of its accumulation in the plant under water ...

  4. Elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Elimination_reaction

    An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism. [2] The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction. The numbers refer not to the number of steps in the mechanism, but rather to the ...

  5. Pyruvate dehydrogenase complex - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_complex

    The E2 subunit from pyruvate dehydrogenase evolved from the E2 gene found in BCOADH while both enzymes contain identical E3 subunits due to the presence of only one E3 gene. Since the E1 subunits have a distinctive specificity for particular substrates, the E1 subunits of pyruvate dehydrogenase and BCOADH vary but share genetic similarities.

  6. Tissue hydration - Wikipedia

    en.wikipedia.org/wiki/Tissue_hydration

    Vascular plants also possess an internal vascular system that distributes fluids throughout the plant. Some xerophytes , such as cacti and other desert plants, have mucilage in their tissues. This is a sticky substance that holds water within the plant, reducing the rate of dehydration.

  7. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.

  8. Ecophysiology - Wikipedia

    en.wikipedia.org/wiki/Ecophysiology

    Plant ecophysiology is concerned largely with two topics: mechanisms (how plants sense and respond to environmental change) and scaling or integration (how the responses to highly variable conditions—for example, gradients from full sunlight to 95% shade within tree canopies—are coordinated with one another), and how their collective effect on plant growth and gas exchange can be ...
