Gene Details:

  • Gene ID: BnaA07G0011300ZS
  • Gene Symbol: BnaA7.CKX2
  • Gene Name: cytokinin oxidase/dehydrogenase
  • Genome:
  • Species: Brassica napus

Functional Descriptions:

  • The transcription factor BnaWRKY10 regulates cytokinin dehydrogenase BnaCKX2 to control cytokinin distribution and seed size in Brassica napus.
  • The quadruple mutants of the four BnaCKX2 homologs were generated. Endogenous CKs were increased in the seeds of the BnaCKX2 quadruple mutants, resulting in a significantly reduced seed size.
  • The TFs BnaWRKY10s were co-expressed with BnaCKX2s| BnaWRKY10s positively regulated seed size by promoting the expression of BnaCKX2s.
  • Overall, the study reveals the distribution of CKs in B. napus tissues, and shows that BnaWRKY10-mediated BnaCKX2 expression is essential for seed size regulation, providing promising targets for oil crop improvement.
