Fig. 1

Obvious morphological and anatomical differences between the gif1 mutant and wild-type sibling in the inflorescence architecture and floral organs. A Developing inflorescence architecture of wild type. B Highly branched ear and branch differentiating axillary meristems (zoom) in the gif1. White arrows point to axillary meristems, yellow arrows point to the spikelet meristems on the branch. C Scanning electron microscopy of developing inflorescence architecture in wild type. D Scanning electron microscopy of branch differentiating axillary meristems in the gif1. E and F Scanning electron microscopy of branches converted from gif1 florets (E) and their enlarged images (F). Arrows point to branches converted from florets. G Scanning electron microscopy of the wild-type floret. H Scanning electron microscopy of the gif1-1 mutant. Asterisk points to the naked ovule primordia. WT, wild type. ca, carpel primordium; st, stamen primordium
