Transcriptome analysis of scl28 and atsmos1

A GRAS family transcription factor, SCL28, and an AP2-type transcription factor, AtSMOS1, both positively regulate cell size in developing organs in Arabidopsis. SCL28 and AtSMOS1 physically interact with each other, and this interaction is essential for transcriptional regulation of downstream genes. To identify the downstream target genes of the SCL28-AtSMOS1 heterodimer, transcriptomes of scl28 and atsmos1 mutants were compared with that of wild type plants.
