Also known as
ATMYB65; myb domain protein 65; MYB DOMAIN PROTEIN 65
Summary
Member of the R2R3-MYB gene family. Similar to GA-induced Barley myb gene. May be induced during germination in response to GA. Double mutants with MYB33 are male sterile, showing defects in pollen development and anther development. Contains a binding site for miRNA159 and may be spatially regulated by this micro RNA. The male sterile phenotype of the MYB33/MYB65 double mutant is light and temperature sensitive. Fertility can be restored with increased light intensity and lower temperatures.

  1. Primary root growth in Arabidopsis thaliana is inhibited by the miR159 mediated repression of MYB33, MYB65 and MYB101
    Title: Primary root growth in Arabidopsis thaliana is inhibited by the miR159 mediated repression of MYB33, MYB65 and MYB101.
  2. MiR159a and miR159b appear to continuously repress MYB33 and MYB65 expression to levels that have no major impact on rosette development.
    Title: Ubiquitous miR159 repression of MYB33/65 in Arabidopsis rosettes is robust and is not perturbed by a wide range of stresses.
  3. There may be factors, in addition to complementarity, that control plant miRNA efficacy, such factors appear to be optimised in regards to the endogenous and ancient miR159:MYB33/65 relationship.
    Title: MicroRNAs with analogous target complementarities perform with highly variable efficacies in Arabidopsis.
  4. MYB33 and MYB65 play no part in gibberellin-mediated growth or flowering in vegetative tissues.
    Title: The microRNA159-regulated GAMYB-like genes inhibit growth and promote programmed cell death in Arabidopsis.
  5. Consistent with functional redundancy, promoter-GUS fusions of MYB33 and MYB65 gave identical expression patterns in flowers (sepals, style, receptacle, anther filaments, and connective but not in anthers themselves), shoot apices, and root tips.
    Title: The Arabidopsis GAMYB-like genes, MYB33 and MYB65, are microRNA-regulated genes that redundantly facilitate anther development.
