Abstract:
... A modified PAMPA (parallel artificial membrane permeability assay) is proposed for evaluating the passive cuticular membrane permeability of potassium in several foliar nutrient formulations. The modified PAMPA can measure the passive permeability of ionic nutrients under fully hydrated conditions through an artificial membrane designed to more closely resemble a plant cuticle, rather than the tra ...

Abstract:
... Atomic Force Microscopy (AFM) is a versatile technique of surface characterization, providing accurate information about the topography and other wide variety of magnitudes at submicron scale. It is extensively utilized in materials science, but its use in other disciplines such as paleobotany is infrequent. In this review, we introduce the main concepts of AFM to paleobotanists, comparing the cha ...

Abstract:
... Although the cuticle is a very thin layer of a few micrometers, it is one of the main remains found among fossil plants. Apparently very fragile, ultrathin cuticle sections of few dozen nanometers thick are studied by using TEM studies and statistical measurements. The ultrastructure details yielded are of significance not only for taxonomy, but also for paleoenvironment and evolution of fossil pl ...

Abstract:
... Predicting plant cuticle-water partition coefficients (Kcw) and understanding the partition mechanisms are crucial to assess environmental fate and risk of organic pollutants. Up to now, experimental Kcw values are determined for only hundreds of compounds because of high experimental cost. For this reason, computational models, which can predict Kcw values based on chemical structures, are promis ...

Abstract:
... Stomatal traits have been shown to vary in predictable ways in response to environmental change in many plant species. As a consequence, stomatal traits in fossil leaves are sometimes used as proxies for past CO2 and climate. Here we investigate the influence of temperature, rainfall and CO2 on stomatal traits in plant cuticle fine details of Melaleuca quinquenervia. We use both modern and fossil ...

Tetraena mongolica Maxim, a relic shrub of the paleo-Mediterranean flora, is normally accompanied in the Western Ordos desert by another plant species in the same taxonomic family, Zygophyllum xanthoxylum (Bunge) Maxim, and together they play a vital role in the ecology of the local environment. Z. xanthoxylum has been identified as having stronger drought tolerance than T. mongolica. As an import ...

Abstract:
... Fusarium graminearum is one of the most destructive plant pathogens worldwide, causing fusarium head blight (FHB) on cereals. F. graminearum colonizes wheat plant surfaces with specialized unbranched hyphae called runner hyphae (RH), which develop multicelled complex appressoria called infection cushions (IC). IC generate multiple penetration sites, allowing the fungus to enter the plant cuticle. ...

Abstract:
... Fungal pathogenicity is governed by environmental factors, with nitrogen playing a key role in triggering pathogenic development. Spores germinating on the plant cuticle are exposed to a nitrogen-free environment, and reprograming of nitrogen metabolism is required for bridging the time needed to gain access to the nitrogen sources of the host. Although degradation of endogenous purine bases effic ...

It is not yet known whether differen ...
