Ectopic Meristem Formation in pnh-2; FIL::PNH cotyledons.
(A) to (F) Scanning electron micrographs of 18-day-old pnh-2; FIL::PNH seedlings forming ectopic meristems on cotyledons on the blade ([A] and [B]) or distal tip of the fusion zone ([C] to [F]). Arrows in (A), (C), and (E) indicate areas magnified in (B), (D), and (F), respectively.
(G) A typical pnh; FIL::PNH seedling at a later stage (∼23 days old). The arrow shows an ectopic meristem developing at the end of one of the cotyledons.
