TI  - Effects of inhibitors of RNA and protein synthesis on aspartate transcarbamylase 
      activity in etiolated plant tissue.
PG  - 232-6
AB  - Aspartate transcarbamylase (ATCase) activity declines in etiolated cowpea (Vigna 
      unguiculata L. Walp.) and soybean (Glycine max L. Merr.) hypocotyls between 3 and 
      11 days after planting. Treating cow-pea hypocotyls with cycloheximide (CH), 
      actinomycin D (AMD), 6-methyl purine (6-MP), or cordycepin increases ATCase 
      activity up to 740, 350, 465, and 305%, respectively, over water-treated controls 
      48 to 72 hours after treatment. In contrast erythromycin had no effect, and 
      d-threo-chloramphenicol (CHL) reduced ATCase activity nearly 40%. CH, AMD, and 
      CHL, whose effects were further characterized, each markedly reduced total RNA 
      synthesis and protein synthesis. Respiration was stimulated by CH and AMD and 
      reduced by CHL. In soybean, CHL-treated tissues and water-treated controls had 
      comparable ATCase activities 48 hours after treatment, while AMD, 6-MP, and CH 
      treatments reduced activities 29, 37, and 78%, respectively. The results suggest 
      that the level of ATCase activity in etiolated cowpea hypocotyls is regulated by 
      a mechanism or mechanisms that are interfered with by inhibition of RNA and 
      protein synthesis. Possibly the mechanism is absent from etiolated soybean 
      hypocotyls.
