Current understanding of the final oxidative steps leading to lignin deposition in trees and other higher plants is limited with respect to what enzymes are involved, where they are localized, how they are transported, and what factors regulate them. With the use of cell suspension cultures of sycamore maple (Acer pseudoplatanus), an in-depth study of laccase, one of the oxidative enzymes possi...

the prevalence of allergic diseases such as asthma and allergic rhinitis is high in general population and aeroallergens are the most common allergens that cause air way inflammation. the aim of this study was an evaluation of clinical and laboratory findings in allergic patients and identification of the most common aeroallergen in these patients. a cross–sectional retrospective study was cond...

Abstract By mitigating the negative effects of urbanization, urban trees contribute significantly to well-being citizens. However, themselves are also exposed stress that can influence tree condition and tree-herbivore interactions. Maple species ( Acer spp.) among most commonly planted in areas throughout North America Europe. Among these species, field, sycamore, Norway maple native Europe, b...

Abstract From 2018 to 2020, Germany experienced periods of exceptional weather conditions. Extremely high summer temperatures and precipitation deficits induced stress mortality in forest trees. Acer pseudoplatanus (sycamore) was one the affected tree species. Symptoms sooty bark disease (SBD) severe damage entire stands, both caused by fungal species Cryptostroma corticale , were reported more...

Brefeldin A (BFA), a specific inhibitor of Golgi-mediated secretion in animal cells, has been used to study the organization of the secretory pathway and the function of the Golgi apparatus in plant cells. To this end, we have employed a combination of electron microscopical, immunocytochemical, and biochemical techniques to investigate the effects of this drug on the architecture of the Golgi ...

the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...

Brefeldin A (BFA), a specific inhibitor of Colgi-mediated secretion in animal cells, has been used to study the organization of the secretory pathway and the function of the Colgi apparatus in plant cells. To this end, we have employed a combination of electron microscopical, immunocytochemical, and biochemical techniques to investigate the effects of this drug on the architecture of the Colgi ...
