Protease and carboxypeptidase activities in the cotyledons of seedlings grown on water increased 15-fold and 7-fold, respectively over a 5-day germination period. The provision of 10 mM NH4+ to the seedlings decreased the enzyme activities by 30% in the cotyledons. A similar decrease in both protease and carboxypeptidase was observed with the hypocotyl of NH4 grown seedlings as compared to water control. Germination was accompanied by a marked decline in leucine aminopeptidase activity, and NH4+ did not appear to have a significant effect on the development pattern of this enzyme. A comparison of glutamine synthetase activity on day 5 between control and NH4+ showed that the enzyme level was repressed by 50%, 30%, and 25% in root, hypocotyl, and cotyledon, respectively, due to NH4+ treatment.The increase in the proteolytic activities were concurrent with a decrease in the protein content of cotyledon and hypocotyl tissues, whereas the proteolytic activities in the root decreased as the protein content declined during development. There was a progressive accumulation of soluble amino acids in the cotyledons of NH4+ grown seedlings with relatively less accumulation in the hypocotyl. The reverse occurred for the seedlings grown on water. These results suggest that exogenously supplied NH4+ during the germination of mung bean seeds slows down protein hydrolysis and the synthesis of glutamine synthetase.</div>","PeriodicalId":23797,"journal":{"name":"Zeitschrift für Pflanzenphysiologie","volume":"114 2","pages":"Pages 151-162"},"PeriodicalIF":0.0,"publicationDate":"1984-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0044-328X(84)80027-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74037066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was an extensive adenosine incorporation into low molecular mass, poly(A) rich RNA composed of 30 to 60 nucleotides during the pre-photoinduction phase immediately after hydration. It was followed by gradual increase in the rate of cytoplasmic rRNA synthesis. Photoinduction by 2 short red irradiations given shortly after the preinduction phase caused an immediate 2 fold increase in the rate of 3H-adenosine incorporation into this low molecular mass RNA followed by a heavy shift to the production of rRNAs starting 10h after photoinduction. An increase in mRNA template activity was observed in a cell free translation system 16h after photoinduction: A 30,000d protein and 48,000d protein were preferentially synthesized. Still, the rate and pattern of 35S-methionine incorporation in vivo remained unchanged during the first two days after photoinduction. Then methionine incorporation rapidly rose to four times the rate of the blue light (non photoinduced) control.
