The T-box factor TBX-2 and the SUMO conjugating enzyme UBC-9 are required for ABa-derived pharyngeal muscle in C. elegans.


The C. elegans pharynx is produced from the embryonic blastomeres ABa and MS. Pharyngeal fate in the ABa lineage is specified by the combined activities of GLP-1/Notch-mediated signals and the TBX-37 and TBX-38 T-box transcription factors. Here, we show another T-box factor TBX-2 also functions in ABa-derived pharyngeal development. tbx-2 mutants arrest as… (More)
