A pot experiment was conducted to evaluate the effects of applying L-methionine (L-MET), L-phenylalanine (LPHE) and L-tryptophan (L-TRP) on the growth of Zea mays and its nutrient uptake, and to determine the optimal application rate of them. The results showed that L-MET, L-PHE and L-TRP could
Anthranilate synthetase, phosphoribosyltransferase, phosphoribosyl anthranilate isomerase, and indoleglycerol phosphate synthetase were examined in partially purified extracts of the monocotyledon, Zea mays and the dicotyledon, Pisum sativum. The plant extracts were chromatographed on DEAE-cellulose
Indole-3-acetic acid (IAA) conjugation is one of the mechanisms responsible for auxin homeostasis. IAA ester conjugates biosynthesis has been studied during development of maize seeds where IAA-inositol (IAInos) and its glycosidic forms make up about 50 % of its ester conjugates pool.
Rats were trained to ingest corn oil emulsion. Such ingestion was accompanied by intragastric injection either of dilute amino acid (e.g., 4.3 mM L-tryptophan) in one group or saline in a second. No significant difference between the two groups was observed at the end of training. However sudden
Streptomyces rugosporus LL-42D005 was shown to produce the novel pyrroindomycin antibiotics. Production of pyrroindomycin (alpha) and chloro-pyrroindomycin (beta) was characterized in a semi-defined fermentation medium containing glucose, casein, phosphate, vitamins and minerals. Accumulation of
