Disease relevance of Amaranthus


High impact information on Amaranthus

  • Structure of benzyl T-antigen disaccharide bound to Amaranthus caudatus agglutinin [3].
  • A newly isolated lectin, Amaranthus caudatus agglutinin (also called amaranthin or ACA), which binds to the Thomsen-Friedenreich antigen (T-antigen) and its sialylated variants, was used as a histochemical probe for proliferating cells in sections of human colonic tissues [4].
  • Betaine-aldehyde dehydrogenase from leaves of Amaranthus hypochondriacus L. exhibits an Iso Ordered Bi Bi steady state mechanism [5].
  • Isolation and characterization of amaranthin, a lectin present in the seeds of Amaranthus caudatus, that recognizes the T- (or cryptic T)-antigen [6].
  • The same predicted amino acid change in psbA was previously shown for an Amaranthus hybridus 'S' and 'R' biotypes which had, in addition, two silent nucleotide changes between the genes (Hirschberg, J. and McIntosh, L., Science 222, 1346-1349, 1983) [7].

Biological context of Amaranthus


Anatomical context of Amaranthus


Associations of Amaranthus with chemical compounds

  • Fructose-6-phosphate,2-kinase and fructose-2,6-bisphosphatase were separated on the basis of charge from leaves of C3 (spinach, lettuce, and pea) and C4 (sorghum and amaranthus) plants but not from rat liver--a tissue known to contain a bifunctional enzyme with both activities [14].
  • 1. A wide range of purine bases, nucleosides and cyclic nucleotides were shown to induce betacyanin synthesis in Amaranthus seedlings [15].
  • Aminophylline was shown to inhibit Amaranthus cyclic AMP phosphodiesterase activity [15].
  • Molecular basis for multiple resistance to acetolactate synthase-inhibiting herbicides and atrazine in Amaranthus blitoides (prostrate pigweed) [16].
  • The third compound with cytokinin activity in Amaranthus caudatus bioassay proved to be a simple phenolic compound with elemental composition C8H10O2 [17].
