MIRNA156 EXPRESSION IN EARLY ANTHERS
The evolutionarily conserved interaction between particular SBP-box genes and miR156 is known to play a key role in the floral transition. The data presented by Xing et al. (pages 3935–3950) show another essential role for this interaction in sexual reproduction, specifically, in the process of microsporogensis in anthers. The cover image shows the expression pattern of a GUS reporter gene driven by the MIR156H promoter region (cyan) in a top view of an Arabidopsis inflorescence apex.
