Model illustrating auxin control of pinna initiation and development of the WT and tl genotypes of pea. An auxin gradient in the initial leaf primordium promotes acropetal pinna initiation. Pinna primordia identify their position in the auxin gradient. Proximal (P) pinnae are more responsive to the Af gene product and a marginal blastozone becomes the site of auxin production; these primordia become leaflets. Distal (D) pinnae are more responsive to the Tl gene product and, as a result, they produce auxin in the tip only; these primordia become tendrils. In the absence of the Tl gene product or when auxin levels are low, the Af gene regulates development and distal pinnae become leaflets
