Shoot branching and plant height are among the key factors that define the overall architecture of plants. We found that overexpression of a cDNA for a zinc-finger protein of petunia, designated Lateral shoot-Inducing Factor (LIF), in transgenic petunia plants resulted in a dramatic increase in lateral shoots and reduced plant height. LIF overexpression also caused a decrease in the number of cells in the stem, leaf, and flower, accompanied by enlargement of cells. trans-Zeatin was decreased...[Show more]
