DOF53_ARATH | developmental stage | In embryos, present in cells relevant for root initiation and later in vascular tissues. At the globular stage, accumulates in cells adjacent to the hypophysis (extra-embryonic cell specified to become the founder cell of the primary root meristem) (PubMed:20220754). Expressed at preprocambial stages first in wide domains, and later confined to sites of vein development. In young seedlings, first observed in the central region of leaves primordia, and later strongly expressed at sites of midvein, first and second loops, and higher-order veins (PubMed:20563990). |
DOF53_ARATH | function | Transcription factor that binds specifically to a 5'-AA[AG]G-3' consensus core sequence (By similarity). 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). |
DOF53_ARATH | tissue specificity | 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) (PubMed:30626969). Accumulates in the stele (PubMed:20563990). |
