Transcription factor that negatively affects seed germination and opposes TCP14 function in the regulation of a specific set of abscisic acid-related genes (PubMed:22155632). The PEAR proteins (e.g. DOF2.4, DOF5.1, DOF3.2, DOF1.1, DOF5.6 and DOF5.3) activate gene expression that promotes radial growth of protophloem sieve elements (PubMed:30626969). Interacts with TCP14. The PEAR proteins (e.g. DOF2.4, DOF5.1, DOF3.2, DOF1.1, DOF5.6 and DOF5.3) form a short-range concentration gradient that peaks at protophloem sieve elements (PSE). The transcript levels of the gene accumulate in dry seeds and decay gradually during after-ripening and also upon seed imbibition. By cytokinin in procambium. The pear1 pear2 dof6 tmo6 quadruple mutant plants showed a uniform reduction in radial growth, associated with compromised symplastic trafficking.
