Evolution of the basic helix-loop-helix transcription factor SPATULA and its role in gynoecium development

SPATULA (SPT) encodes a basic helix-loop-helix transcription factor in Arabidopsis thaliana that functions in the development of the style, stigma and replum tissues, all of which arise from the carpel margin meristem of the gynoecium. Here we use a comparative approach to investigate the evolutiona...

Description
Summary:SPATULA (SPT) encodes a basic helix-loop-helix transcription factor in Arabidopsis thaliana that functions in the development of the style, stigma and replum tissues, all of which arise from the carpel margin meristem of the gynoecium. Here we use a comparative approach to investigate the evolutionary history of SPT and identify changes that potentially contributed to its role in gynoecium development.
