Irradiation of previously dark-grown cell suspension cultures from parsley (Petroselinum hortense Hoffm.) with ultraviolet light caused large, concomitant increases in mRNA activities for two characteristic enzymes of phenylpropanoid metabolism, phenylalanine ammonia-lyase, and flavanone synthase. The rates of enzyme synthesis both in vitro in a reticulocyte lysate and in vivo were quantitated ...
Phenylalanine ammonia-lyase (EC 4.3.1.5) from parsley is posttranslationally modified by dehydrating its Ser-202 to the catalytically essential dehydroalanine prosthetic group. The codon of Ser-202 was changed to those of alanine and threonine by site-directed mutagenesis. These mutants and the recombinant wild-type enzyme, after treatment with sodium borohydride, were virtually inactive with L...
L-Phenylalanine is one of the essential amino acids that cannot be synthesized in mammals in adequate amounts to meet the requirements for protein synthesis. Fungi and plants are able to synthesize phenylalanine via the shikimic acid pathway. L-Phenylalanine, derived from the shikimic acid pathway, is used directly for protein synthesis in plants or metabolized through the phenylpropanoid pathw...
The nonselective herbicide glyphosate (n-[phosphonomethyl]glycine) inhibited the light-induced accumulation of phenylpropanoid substances (chlorogenic acid, procyanidin, rutin, anthocyanin) in etiolated buckwheat hypocotyls 90% at 1 millimolar. Structurally related compounds, such as n,n-bis[phosphonomethyl]glycine, aminomethylphosphonate, methylglycine, and iminodiacetate, had little or no inh...
Barley (Hordeum vulgare L.) is one of the most used species for hydroponic green fodder. The chemical properties fodders may be enhanced through use various strategies during crop production, including stress applications. In this context, hydrogen peroxide (H2O2) as a factor in controlled elicitation, technique to increase secondary metabolites food. aim research was evaluate possibility using...
To assess nickel-induced toxicity in plants, Zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 50-200 μM for a period of two weeks. Observed biological makers included biomass, soluble and total protein contents, and the activities of guaiacol peroxidase (GPX), ascorbate peroxidase (APX), catalase (CAT), and phenylalanine ammonia-lyase (PAL) in the l...
In order to study on different methods of application of polyamines (putrescine, spermine, spermidine) on some morphological, physiological, enzymatic and vase life of Rosa hybrida cv. ‘Dolce Vita’, experiment was conducted as a factorial experiment in a completely randomized design with 32 treatments, 3 replicates and each replication containing 5 vases, a total of 480 vases were executed. Fir...
