text: Yo, check it out, I got a story to tell,
  'Bout the antifungal activities, sulfur's where it dwells.
  Pathogen infection, sulfur metabolism's link,
  And the sulfate nutritional status, that's what makes plants think.
  
  We took Arabidopsis thaliana, put 'em to the test,
  Different sulfur regimes, see which one's the best.
  Plants with 500 μM sulfate, they held their ground,
  Less infected by Alternaria brassicicola, that's what we found.
  
  When the infection hit, things started to change,
  Camalexin, a defense compound, it rearranged.
  Sulfur-rich defensin, genes were turned on,
  Plants with optimal sulfate, they were strong.
  
  Sulfite and O-acetylserine, they started to rise,
  Cysteine biosynthetic enzymes, they were no surprise.
  Sulfur metabolism, it got a boost,
  Under higher sulfate supply, it was loose.
  
  So listen up, y'all, there's more to this tale,
  Pathogen activation, sulfur's on the trail.
  Sulfate nutritional status, it's sensed by the plant,
  Contributing to defense, that's what we chant.
