Alpha-amylase conserved element gene transcriptions

Associate Editor(s)-in-Chief: Henry A. Hoff

"A few genes were also noticed with the shoot (GATAatGATG) and root (TGACGTCA) specific elements, cell cycle regulation (CCCAACGGT), seed-specific element (CATGCATG) and alpha-amylase conserved elements (TATCCATCCATCC). The presence of a significant number of the regulatory elements suggests strong participation of the U-box E3 gene family in plant development and responses under abiotic and biotic stress conditions. The data also supports the active involvement of the U-box E3 gene family in hormonal regulatory pathways."[1]

Consensus sequences

TATCCATCCATCC[1]

Hypotheses

  1. A1BG has no A boxes in either promoter.
  2. A1BG is not transcribed by an ATA box.
  3. AGCE1 does not participate in the transcription of A1BG.

Alpha-amylase conserved element samplings

Copying a responsive elements consensus sequence TATCCA 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.

Comparison:

The occurrences of real AACp UTRs and distals are greater than the randoms. This suggests that the real AACps are likely active or activable.
