Gene Details:

  • Gene ID:
  • Gene Symbol: SlCCD7
  • Gene Name: carotenoid cleavage dioxygenase 7
  • Genome: Tomato Genome version SL4.0
  • Species: Solanum lycopersicum

Functional Descriptions:

  • SlCCD7 controls strigolactone biosynthesis, shoot branching and mycorrhiza-induced apocarotenoid formation in tomato.
  • SlCCD7 encodes an enzyme capable of cleaving cyclic and acyclic carotenoids. However, the SlCCD7 protein has 30 additional amino acids of unknown function at its C terminus. Tomato plants expressing a SlCCD7 antisense construct display greatly increased branching.
  • A targeted analysis of strigolactones and AM-induced apocarotenoids revealed major decreases in the levels of these compounds in the SlCCD7 antisense lines.
  • The germination rate of Orobanche ramosa seeds was reduced by up to 90% on application of extract from the SlCCD7 antisense lines, compared with the wild type. Additionally, upon mycorrhizal colonization, C13 cyclohexenone and C14 mycorradicin apocarotenoid levels were greatly reduced in the roots of the antisense lines, implicating SlCCD7 in their biosynthesis.
