Another missing link..?

Li, Jin et al. show how #MYB factor (MYB41) is involved in the crosstalk between cell wall mannose & #brassinosteroid signalling pathways, thereby promoting lateral root development in #Mirabilis jalapa

Proposed model for MirMAN-mediated mannose regulation of lateral root development. MirMAN-mannose activates BR biosynthesis via AtMYB41, which in turn potentiates auxin signaling, ultimately working synergistically to promote root development.
