MYB44 regulates PTI by promoting the expression of EIN2 and MPK3/6 in Arabidopsis.
Title: MYB44 regulates PTI by promoting the expression of EIN2 and MPK3/6 in Arabidopsis.
Transcription factors KANADI 1, MYB DOMAIN PROTEIN 44, and PHYTOCHROME INTERACTING FACTOR 4 regulate long intergenic noncoding RNAs expressed in Arabidopsis roots.
Title: Transcription factors KANADI 1, MYB DOMAIN PROTEIN 44, and PHYTOCHROME INTERACTING FACTOR 4 regulate long intergenic noncoding RNAs expressed in Arabidopsis roots.
These results indicate that MYB44 suppresses polymerase-mediated transcription of the LEA4-5.
Title: AtMYB44 suppresses transcription of the late embryogenesis abundant protein gene AtLEA4-5.
AtMYB44 forms a complex with TPR corepressors and recruits histone deacetylase(s) to suppress PP2C gene transcription in a signal-independent manner.
Title: AtMYB44 interacts with TOPLESS-RELATED corepressors to suppress protein phosphatase 2C gene transcription.
salt stress induces the eviction of H2A.Z-containing nucleosomes from the AtMYB44 promoter region.
Title: H2A.Z-containing nucleosomes are evicted to activate AtMYB44 transcription in response to salt stress.
AtMYB44 might participate in the 3OC6-HSL-mediated primary root growth via regulating the expression of cytokinin- and auxin-related genes. The data establish a genetic connection between the regulatory role of AtMYB44 in phytohormones-related gene expression and plant response to the bacterial QS signal.

the C-terminal side of the protein, but not the N-terminal side of the R2R3 domain, contributes to the functional activity and specificity of AtMYB44 through interactions with other regulators generated by each of a variety of stimuli.
Title: Quadruple 9-mer-based protein binding microarray analysis confirms AACnG as the consensus nucleotide sequence sufficient for the specific binding of AtMYB44.
