Abstract: [Object] An object of the present invention is to provide, for the purpose of preventing or suppressing stress at a cellular level, a composition containing a plant-derived polyamine-containing extract that has a stress-reducing action, an anti-stress action, a stress-suppressing action, a stress-preventing action, a stress-inhibiting action, a stress protective action, or the like. Another object of the present invention is to provide cosmetics, quasi drugs, medical supplies, sanitary goods, pharmaceuticals, foods, or drinks that each contain such a composition. [Solution] A stress-reducing agent including a plant-derived polyamine-containing extract serving as an active component is provided.

Abstract: The invention provides a method for producing a transgenic plant, as well as the plant produced from the method and the progeny of the plant. The method comprises transforming a cell of a plant with an exogenous spermidine synthase coding sequence, expressing the exogenous spermidine synthase coding sequence in the transformed cell, and generating a plant from the transformed cell. The transgenic plant has improved environmental stress tolerance against at least two environmental stresses selected from drought stress, herbicidal stress, oxidation stress, cold stress, osmotic stress, and salt stress as compared to a plant of the same species lacking the exogenous spermidine synthase coding sequence.

Abstract: The present invention provide methods of imparting stress tolerance, characterized in that an expression amount of at least one stress defense gene is increased compared with a non-transformant by transforming the plant with an exogenous spermidine synthase (SPDS) gene, an exogenous S-adenosylmethionine decarboxylase (SAMDC) gene, an exogenous arginine decarboxylase (ADC) gene, an ornithine decarboxylase (ODC) gene and/or a spermine synthase (SPMS) gene under the control of a promoter capable of functioning in the plant.

Abstract: Cotton plants of the genus Gossypium with improved cotton fiber characteristics are disclosed. The cotton plant has an expression cassette containing a gene coding for an enzyme selected from the group consisting of endoxyloglucan transferase, catalase and peroxidase so that the gene is expressed in cotton fiber cells to improve the cotton fiber characteristics. Also disclosed is a method for producing cotton fibers with improved fiber characteristics from these cotton plants.

Abstract: Methods are disclosed to achieve an improvement in the characteristics and yield of cotton fibers. In one method, a cotton plant of the genus Gossypium in seed form or in growth stage is treated with a brassinosteroid. In another method, an ovule culture is prepared from a cotton plant of the genus Gossypium in a brassinosteroid-containing liquid medium. Cotton fibers with improved fiber characteristics are obtained from the cotton bolls of the treated plant or from the cultured ovules.
