Cryptic bracts exposed: insights into the regulation of leaf expansion.
Arabidopsis is unusual in producing flowers that are not subtended by specialized leaves, called floral bracts. Writing in Development, Dinneny et al. and Ohno et al. show that gain-of-function mutations of the JAGGED transcription factor produce bracts, and provide evidence that this gene plays a key role in a developmental program that regulates the size and shape of all leaves and leaf-homologs.
