High impact information on Conyza

  • Transient, oxidant-induced antioxidant transcript and enzyme levels correlate with greater oxidant-resistance in paraquat-resistant Conyza bonariensis [1].
  • Inheritance of evolved glyphosate resistance in Conyza canadensis (L.) Cronq [2].
  • Three new pyrone glucosidic derivatives, together with the known pyromeconic acid glucoside, three acytelenes and two eudesmanes, were obtained from the aerial parts of Conyza albida [3].
  • Shikimate concentrations in resistant populations declined about 40% from 2 to 4 DAT, while shikimate concentrations in the susceptible horseweed plants increased about 35% from 2 to 4 DAT [4].
  • Conyzasaponins I-Q, nine new triterpenoid daponins from Conyza blinii [5].
 

Anatomical context of Conyza

  • The differential induction of higher levels of mRNAs, cytosol and chloroplast antioxidant enzyme activities, and proteins occurred after sub-lethal paraquat treatment of the oxidant-resistant biotype of Conyza bonariensis (L.) Cronq [1].
 

Associations of Conyza with chemical compounds

 

Analytical, diagnostic and therapeutic context of Conyza

  • Oral administration of methanol extract from Conyza dioscoridis (CD) or Alhagi maurorum (AM) in a 200 mg kg(-1) dose exhibits a significant antidiarrhoeal effect against castor oil-induced diarrhoea, while Mentha microphylla (MM), Convolvulus arvensis (CA), Conyza linifolia (CL) produced no significant effect [9].
