Palmate-like pentafoliata1 encodes a novel Cys(2)His(2) zinc finger transcription factor essential for compound leaf morphogenesis in Medicago truncatula.

ABSTRACT: As the primary site for photosynthetic carbon fixation and the interface between plants and the environment, plant leaves play a key role in plant growth, biomass production and survival, and global carbon and oxygen cycles. Leaves can be simple with a single blade or compound with multiple units of blades known as leaflets. In a palmate-type compound leaf, leaflets are clustered at the tip of the leaf. In a pinnate-type compound leaf, on the other hand, leaflets are placed on a rachis in distance from each other. Higher orders of complexities such as bipinnate compound leaves of the "sensitive" plant, Mimosa pudica, also occur in nature. However, how different leaf morphologies are determined is still poorly understood. Medicago truncatula is a model legume closely related to alfalfa and
