"Cytokinin employs a two-component multi-step phosphorelay for its perception and signaling transduction12–14. In Arabidopsis, there are three cytokinin receptors (ARABIDOPSIS HISTIDINE KINASEs; AHK2, 3, 4) and eleven type-B response regulators (ARABIDOSPIS RESPONSE REGULATORs; B-ARRs)8,15."[1]
"The cytokinin transcriptional response centrally affects the family of ARRs. Type-B ARRs (B-ARRs) are transcription factors (TFs) with a GARP-like DNA binding domain at their C-termini and a receiver domain at their N-termini. Type-A ARRs (A-ARRs) are similar to the N-termini receiver domain of B-ARRs but do not possess a DNA binding domain."[1]
Consensus sequences
ARR1: AGATT(C/T), ARR10: (A/G)GATA(A/C)G, ARR12: (A/G)AGATA.[1]

Hypotheses
- A1BG has no regulatory elements in either promoter.
- A1BG is not transcribed by a regulatory element.
- No regulatory element participates in the transcription of A1BG.
ARR1 Cytokinin samplings
Copying a responsive elements consensus sequence AGATT(C/T) and putting the sequence in "⌘F" finds none between ZNF497 and A1BG or none between ZSCAN22 and A1BG as can be found by the computer programs.
For the Basic programs testing consensus sequence AGATT(C/T) (starting with SuccessablesARR1.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
- negative strand, negative direction, looking for AGATT(C/T), 0.
- positive strand, negative direction, looking for AGATT(C/T), 1, AGATTC at 2452.
- positive strand, positive direction, looking for AGATT(C/T), 1, AGATTC at 122.
- negative strand, positive direction, looking for AGATT(C/T), 1, AGATTT at 2869.

- complement, positive strand, negative direction, looking for TTTTTTTT, 0.
- complement, positive strand, positive direction, looking for TTTTTTTT, 0.
