text: Phenolic acids, yo, major secondary metabolites,
  In Salvia miltiorrhiza, they be the bioactive constituents.
  Enzyme-encoding genes and transcription factors,
  Phenolic acid biosynthesis, we be discoverin', no bluff.
  
  Check it, the S. miltiorrhiza got SmKFB5,
  Kelch repeat F-box protein keepin' it alive.
  Physically interacts with three PAL isozymes,
  Proteolytic turnover, ubiquitin's the rhyme.
  
  Post-translational regulation, it's poorly understood,
  But SmKFB5 be doin' what it should.
  Controlling the turnover of PAL, no doubt,
  Negatively impactin' phenolic acids, that's what it's about.
  
  Hairy root of S. miltiorrhiza, listen to this,
  Methyl jasmonate, suppressin' SmKFB5, no miss.
  But SmPAL1 and SmPAL3, they be risin' high,
  Transcription increased, phenolic acids amplify.
  
  Methyl jasmonate, it be doin' its thing,
  Consolidatin' regulation, both post and transcriptional it bring.
  Phenolic acid biosynthesis, it be enhanced,
  Molecular mechanisms, SmKFB5 got it advanced.
  
  Plant breeders, pay attention to this call,
  SmKFB5, a valuable target, ain't no stall.
  Tailor new cultivars with precision and grace,
  Using the knowledge we got, puttin' plants in their place.
