Gene Details:

  • Gene ID:
  • Gene Symbol: PyBBX24
  • Gene Name: B-box zinc finger protein 24
  • Genome:
  • Species: Pyrus communis

Functional Descriptions:

  • Allelic variation of BBX24 (PyBBX24) is a dominant determinant controlling red coloration and dwarfism in pear.
  • Stable overexpression of PyBBX24ΔN14 exhibits a dwarfing phenotype in Arabidopsis, tobacco, and tomato plants. PyBBX24ΔN14 can activate the expression of PyGA2ox8 via directly binding to its promoter, thereby deactivating bioactive GAs and reducing the plant height. However, the nuclear localization signal (NLS) and Valine-Proline (VP) motifs in the C-terminus of PyBBX24 reverse these effects.
  • PyBBX24ΔN14 directly activates the transcription of PyUFGT and PyMYB10 through interaction with PyHY5.
  • We conclude that mutations in PyBBX24 gene link both an increase in pigmentation and a decrease in plant height.
