Abstract Background Cadmium (Cd) pollution has brought harm to the growth and development of potato. Glutathione (GSH) is an important antioxidant that may play active role in response a potato Cd stress. However, how GSH influences effect on potatoes unknown. In this study, we investigated effects exogenous phenylpropanoid biosynthesis pathway plant hormone signal transduction under stress exp...

Fusarium oxysporium f. sp. cubense (Foc) race is an archetypally soil-born fungus causing chief fiscal damage to farmers growing banana plants. Supervising Foc attained by the habit of chemical fungicides which undesirably harm soil fertility. Our investigations intended activate aptitude Trichoderma strains for activation PGPR and IIR. The accretion defence enzymes such as Polyphenol Oxidase (...

Divalent Mn ions cause an increase in the level of phenylalanine ammonia-lyase in gherkin hypocotyls. With the exception of Mg ions, which had a small effect, no other metal ion has so far been found which could replace the Mn ion in this respect. Invertase and peroxidase were not significantly affected by the Mn treatment. The increase in phenylalanine ammonialyase activity is explained by the...

Because of its key role in secondary phenylpropanoid metabolism, Phe ammonia-lyase is one of the most extensively studied plant enzymes. To provide a basis for detailed structure-function studies, the enzyme from parsley (Petroselinum crispum) was crystallized, and the structure was elucidated at 1.7-A resolution. It contains the unusual electrophilic 4-methylidene-imidazole-5-one group, which ...

In recent years, the application of natural substances on crops has been intensified in order to increase the resistance and yield of the soybean crop. Among these products are included plant biostimulants that may contain algae extracts, amino acids, and plant regulators in their composition. However, there is little information on the isolated effect of each of these constituents. The objecti...

Basal stem rot, caused by the basidiomycete fungus, Ganoderma boninense, is an economically devastating disease in Malaysia. Our study investigated the changes in lignin content and composition along with activity and expression of the phenylpropanoid pathway enzymes and genes in oil palm root tissues during G. boninense infection. We sampled control (non-inoculated) and infected (inoculated) s...

Willow is an important biomass crop for the bioenergy industry, and therefore optimal growth with minimal effects of biotic and abiotic stress is essential. The phenylpropanoid pathway is responsible for the biosynthesis of not only lignin but also of flavonoids, condensed tannins, benzenoids and phenolic glycosides which all have a role in protecting the plant against biotic and abiotic stress...

Here we reported a novel protein elicitor from Bacillus amyloliquefaciens NC6 induced systemic resistance (ISR) in tobacco. The purification was executed by ion-exchange chromatography, native-page extraction and HPLC, and the amino acid sequence was identified by mass spectrometry. This recombinant elicitor protein, expressed in Escherichia coli by an E1 expression vector, had good thermal sta...

Background: Flavonoids of Hypericum perforatum are important secondary metabolites which have been widely utilized in medicine for a range of purposes. The use of methyl jasmonate (MeJA) elicitation for the enhancement of flavonoid production in cell suspension culture of H. perforatum would be an efficient alternative method for the flavonoid production. Results: MeJA influenced the cells grow...

The timing o f changes in the protein synthesis pattern o f elicitor-treated, [35S]methioninelabelled parsley cells ( Petroselinum crispum) was analyzed by two-dimensional gel electropho­ resis. Five groups were distinguished from a large number o f elicitor-responsive as well as un­ responsive proteins. Two groups were synthesized de novo either early or late after elicitor ap­ plication; two ...
