Unfavourable climate conditions, pathogen attacks and certain states of plant development trigger the expression of so-called stress proteins. From the moment the plant receives the stimulation signal until it synthesizes the stress-response proteins, several different processes take place: recognition of the stress factor, synthesis of secondary metabolites that act as transduction signals, expression of the genes and, finally, synthesis of the different stress proteins

The present work points out to the interdisciplinary experimental results, obtained in the experimental fields of the Plant Protection and Soil Science Department, as well as at data which stress upon the interdependency between the satisfaction of the trophically needs of the wheat plants and the aggressiveness of the pathogens which cause the disease.The experimental results underline the fact that the attack level expressed through intensity and attack degree is different, both with the ...

Foliar tissue evaluations of macro and micro nutrient concentrations were conducted on a mature mixed stand of "Penn A4" creeping bentgrass (Agrostis stolonifera) and annual bluegrass (Poa annua) at the Valentine Turfgrass Research Center, Penn State University, University Park, PA. The objective of the study was to determine if selected micronutrient containing materials could increase the macro and micro nutrient levels in foliar tissue of the turfgrass plant, effect color, and increase gr...

One evolutionary way living organisms fight infections consists in the production of several peptides with antimicrobial activity. Recently, peptides with direct (especially on Gram-negative bacteria) and indirect antimicrobial activity, antifungal, anti-inflammatory and vasodilator activity have been discovered.
