Photosystem II Inhibitor

Photosystem II Inhibitors (3):

Cat. No. Product Name Effect Purity
  • HY-B1876
    Nicosulfuron
    		Inhibitor
    Nicosulfuron is efficient, harmless, antifungal and selective herbicide belonging to the sulfonylurea family. Nicosulfuron is also a photosynthetic system inhibitor and inhibits acetolactate synthase (ALS) enzyme activity. Nicosulfuron degradation by Plectosphaerella cucumerina AR1 is glucose concentration dependent in planktonic lifestyle. Nicosulfuron enhances the glycolysis pathway and tricarboxylic acid cycle to improve the adaptability of sweet maize. Nicosulfuron reduces the synthesis of branched-chain amino acids (BCAAs), which is proming for maize cultivation.
  • HY-121242
    Buthidazole
    		Inhibitor
    Buthidazole is a selective herbicide for weed control in corn. Buthidazole inhibits photosynthetic electron transport at two distinct sites in the photosynthetic electron transport chain. The major site of inhibition was on the reducing side of photosystem II. Another site of electron transport inhibition is on the oxidizing side of photosystem II. Buthidazole inhibits corn photosynthesis and prevents starch accumulation in bundle sheath chloroplasts and some ultrastructural disruption of mesophyl chloroplasts of corn plants.
  • HY-111998
    Stigmatellin
    		Inhibitor
    Stigmatellin is an antibiotic against yeasts, filamentous fungi and several Gram-positive bacteria, derived from the cell mass of the myxobacterium. Stigmatellin is also a powerful inhibitor of photosynthetic electron transport. Stigmatellin uses various sugars, polysaccharides and acids of the citrate cycle as substrates and inhibits RNA and protein synthesis. Stigmatellin has two different inhibition sites. One is located at the reducing side of Photosystem II. Another one is located at the cytochrome b6/f-complex. Stigmatellin is promising for research of antimicrobial and photosynthesis.
