Gene Details:

  • Gene ID:
  • Gene Symbol: AaHD1
  • Gene Name: HOMEODOMAIN PROTEIN 1
  • Genome:
  • Species: Artemisia annua

Functional Descriptions:

  • HOMEODOMAIN PROTEIN 1 (AaHD1) is required for jasmonate-mediated glandular trichome initiation in Artemisia annua.
  • By searching transcription factors regulated by JA in Artemisia annua, we identified a novel homeodomain-leucine zipper transcription factor, HOMEODOMAIN PROTEIN 1 (AaHD1), which positively controls both glandular and nonglandular trichome initiations.
  • Overexpression of AaHD1 in A. annua significantly increased glandular trichome density without harming plant growth. Consequently, the artemisinin content was improved.
  • AaHD1 knockdown lines show decreased sensitivity to JA on glandular trichome initiation, which indicates that AaHD1 plays an important role in JA-mediated glandular trichome initiation.
  • AaSPL9 affects glandular trichomes initiation by positively regulating expression of AaHD1 in Artemisia annua L.
  • AaSPL9 could positively regulate the initiation of glandular trichome and artemisinin content in A. annua.
