Protein: Protein DA1-related 2 (Protein LATERAL ROOT DEVELOPMENT 3) (Q0WSN2)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Acts redundantly with DA1 and DAR1 to regulate endoreduplication during leaf development. Together with DA1 and DAR1, modulates the protein stability of the transcription factors TCP14 and TCP15, which repress endoreduplication by directly regulating the expression of cell-cycle genes. Involved in root phloem development. Is an essential component of early phloem development, long-distance delivery of phloem content, and proper maintenance of root system architecture. Involved in the control of root meristem size. Functions genetically downstream of cytokinin and IAA3 to maintain normal auxin distribution by influencing polar auxin transport. Acts through the PLETHORA pathway, upstream of PLT1 and PLT2 to influence root stem cell niche activity and thus control root meristem size.
