"Cytokinin fulfills its diverse roles in planta through a series of transcriptional responses."[1]

Human genes

Gene expressions

Interactions

"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]

Binding site for

Enhancer activity

Promoter occurrences

Hypotheses

  1. A1BG has no regulatory elements in either promoter.
  2. A1BG is not transcribed by a regulatory element.
  3. 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 one between ZNF497 and A1BG or one 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:

  1. negative strand, negative direction, looking for AGATT(C/T), 0.
  2. positive strand, negative direction, looking for AGATT(C/T), 1, AGATTC at 2452.
  3. positive strand, positive direction, looking for AGATT(C/T), 1, AGATTC at 122.
  4. negative strand, positive direction, looking for AGATT(C/T), 1, AGATTT at 2869.
  5. inverse complement, negative strand, negative direction, looking for (A/G)AATCT, 1, AAATCT at 50.
  6. inverse complement, positive strand, negative direction, looking for (A/G)AATCT, 0.
  7. inverse complement, positive strand, positive direction, looking for (A/G)AATCT, 0.
  8. inverse complement, negative strand, positive direction, looking for (A/G)AATCT, 2, GAATCT at 2725, GAATCT at 2243.

ARR1 distal promoters

Negative strand, negative direction: AAATCT at 50.

Positive strand, negative direction: AGATTC at 2452.

Negative strand, positive direction: AGATTT at 2869, GAATCT at 2725, GAATCT at 2243.

Positive strand, positive direction: AGATTC at 122.

ARR10 Cytokinin samplings

Copying a responsive elements consensus sequence (A/G)GATA(A/C)G 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 (A/G)GATA(A/C)G (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:

  1. negative strand, negative direction, looking for (A/G)GATA(A/C)G, 0.
  2. positive strand, negative direction, looking for AAAAAAAA, 0.
  3. positive strand, positive direction, looking for AAAAAAAA, 0.
  4. negative strand, positive direction, looking for AAAAAAAA, 0.
