APUM23 plays pleotropic roles in plant development. (A) Adaxial and abaxial surfaces of leaf 5 of 21-d-old Col and apum23-3 plants. (B) Outline of leaves from Col (upper) and apum23-3 (lower), indicating the delayed transition from juvenile to adult stage: light grey indicates leaves lacking abaxial trichomes; black indicates leaves with abaxial trichomes; red indicates bracts. (C) The rate of leaf initiation in Col and apum23-3: the first visible leaf appears 2 d later in apum23-3 but leaf production persists longer, resulting in more leaves (n = 20). (D) Camera-lucida drawings of the adaxial and abaxial mesophyll layers of leaf 5 in Col and apum23-3. (E) Chloral hydrate-cleared leaves of Col and apum23-3 show reduced complexity of vascular strands in apum23-3. (F) Root growth of Col and apum23-3 on 1/2 MS media. Bar, 1cm (A) and 1mm (E) (this figure is available in colour at JXB online).
