2. Figure 1
A Schematic Representation of Key Elements of the Local and Systemic Signaling Pathways between Shoot and Root and Their Hypothetical Interactions.
Arrows represent positive regulatory actions of one element of the network on another. A T-shaped line represents a negative regulatory action of one element of the network on another. Dashed arrows represent the translocation of one molecule from one part of the plant to another one. Common systemic pathways involving auxin, cytokinins, and sucrose that are involved in different constitutive and adaptive developmental pathways are depicted in black. Elements specific to the MAX/strigolactone signaling pathway are depicted in orange. Elements specific to the bypass pathway are depicted in red. Elements specific to the nitrate responsive pathway are depicted in blue. Elements specific to the phosphate-responsive pathway are depicted in green. ANR1, Arabidopsis Nitrate Regulated 1; ARF8, Auxin Response Factor 8; ARF19, Auxin Response Factor 19; AUX, auxin; BSP, Bypass1-related signal; BSP1, bypass1; CK, cytokinins; CRE1, Cytokinin Response Element 1; GLU, glutamate; MAX1, More AXillary growth 1; MAX2, More AXillary growth 2; MAX3, More AXillary growth 3; MAX4, More AXillary growth 4; MYB62, Myeloblastosis 62; N, nitrate; NRT1.1, Nitrate Transporter 1.1; P, phosphate; PHO2, phosphate deficient 2; PHO3: phosphate deficient 3; PHR1, Phosphate Starvation Response 1; PHR2, Phosphate Starvation Response 2; RAM, Root Apical Meristem; SAM, Shoot Apical Meristem; SCR, Scarecrow; STRG, strigolactone; SUC, sucrose; SUC2, Sucrose Transporter 2; ZAT6, Zinc finger of Arabidopsis thaliana 6. Systemic signals are: AUX, BSP, CK, GLU, miR399, STRG, SUC; other components of the diagram are involved in local production or response to these systemic signals or involved in local N and P signal transduction pathways involved in adaptive root development.
