Abstract:
1. A method for producing plants with improved morphogenesis, which method comprises the steps of: (1) transforming cells of a plant with at least one expression vector containing a plant spermidine synthase (SPDS) gene under the control of one or more promoters capable of functioning in plants, (2) regenerating plant bodies from the transformed cells, (3) cultivating the plant bodies under normal conditions, (4) evaluating the cultivated plants for improved morphogenesis and increased spermidine content compared to the plant prior to transformation with the plant SPDS gene, and (5) selecting cultivated plants having improved morphogenesis as compared to the plant prior to transformation with the plant SPDS gene, wherein the improved morphogenesis is one or more traits selected from the group consisting of: (i) increased number of seeds, grains or ovules, (ii) increased number of flowers, (iii) increased number of ovaries, fruit, cotton balls, pods, ears, or capsules, (iv) increased number of stems, main stems, side stems, flower stalks, trunks, or branches, (v) increased number of leaves, (vi) extended flower blooming period, (vii) increased development period from bearing to maturity of ovaries, fruit, pods, or capsules, and (viii) increased number of roots or tuberous roots.
