Putative p24 complexes in Arabidopsis contain members of the delta and beta subfamilies and cycle in the early secretory pathway

2013

p24 proteins are a family of type I membrane proteins localized to compartments of the early secretory pathway and to coat protein I (COPI)- and COPII-coated vesicles. They can be classified, by sequence homology, into four subfamilies, named p24α, p24β, p24γ, and p24δ. In contrast to animals and fungi, plants contain only members of the p24β and p24δ subfamilies, the latter probably including two different subclasses. It has previously been shown that transiently expressed red fluorescent protein (RFP)-p24δ5 (p24δ1 subclass) localizes to the endoplasmic reticulum (ER) at steady state as a consequence of highly efficient COPI-based recycling from the Golgi apparatus. It is now shown that tr…

Real-time Fluorescence Measurement of Enterovirus Uncoating

2019

Viruses need to open, i.e., uncoat, in order to release their genomes for efficient replication and translation. Especially for non-enveloped viruses, such as enteroviruses, the cues leading to uncoating are less well known. The status of the virus has previously been observed mainly by transmission electron microscopy using negative staining, cryo electron microscopy, X-ray crystallography or gradient separation (reviewed in Tuthill et al., 2010, Myllynen et al., 2016, Ruokolainen et al., 2019). However, monitoring of uncoating has been limited by the lack of methods detecting dynamic changes of the virions. Here, we present a real-time fluorescence based protocol, which detects the viral …

Horticultural management of Italian Pistachio orchard systems: current limitations and future prospective

2019

Pistachio production and consumption have strongly increased in the last years due to its capability to grow under limiting conditions, the profitability of this nut in the market and its well claimed healthy properties. The Sicilian pistachio industry is diminutive in comparison to big producing countries such as California and Iran. Its economical profitability is limited by a low productivity per surface area, strong alternate bearing, and long unproductive period, mainly associated with the lack of implementation of innovative management practices. This “traditional” agricultural system is surviving in a highly competitive international market thanks to the unique organoleptic profile o…

Socioekoloģiskās sistēmas pieeja pilsētas zaļās infrastruktūras plānošanā: Hunzes upes koridora piemērs Groningenā

2019

Pilsētu var uzskatīt par daudzšķautņainu organismu, kas pastāv pateicoties gan pilsētas ekosistēmas iekšējiem, gan arī ārējiem resursiem, taču pieaugot iedzīvotāju skaitam, noslogojums uz pilsētā pastāvošajām dabas teritorijām un kultūrmantojumu nemitīgi pieaug. Pilsētvide veidošanā tiek izmantoti stingri noteikti pārvaldības instrumenti, kā arī pilsētvides apsaimniekošanā tiek izmantoti tehniski pārvaldības risinājumi. Līdz ar to pilsētas kļūs par neelastīgām un izteikti cilvēku kontrolētām sistēmām, kuras zaudē spēju pielāgoties neprognozētu ārējo faktoru iedarbībai. Arī pilsētas kultūrvēsturiskās sejas zaudēšana atstāj nospiedumu uz vietas identitātes un labklājības jautājumiem. Tā iemes…

Wooden biochar as a carrier for endophytic isolates

2017

Abstract Plant growth promoting microorganisms (PGPM) serve as a basis for bio-fertilizers. The aim of this study was to evaluate the wood-derived biochar as a potential carrier for PGPM, previously isolated from plants. The selected microbial consortium was compatible with aged biochar obtained from tree branches and processed at temperatures of 600–800 °C. The effect of the consortium or biochar alone and biochar carrier-based bio-formulation on plant growth was estimated in a 14-day greenhouse experiment with barley. The length of shoots and roots increased by 46% and 32% respectively in comparison with control. Synergy of consortium with biochar was observed regarding root length. Conso…

Impact of Green Manure and Vermicompost on Soil Suppressiveness, Soil Microbial Populations, and Plant Growth in Conditions of Organic Agriculture of…

2015

The impact of organic amendments on the soil microorganisms and plant growth and health in conditions of organic agriculture of Northern temperate climate was analyzed. Some case studies dealing with green manure or vermicompost amendments are discussed giving deeper analyses of the vermicompost impact on plant growth. The first case study is about the impact of green manure on soil microbial populations and soil suppressiveness against such pathogens as late blight, potato scab, and black scurf of potato in organic agriculture. The second case study is about the use of vermicompost in organic starch potato cultivation. Significantly higher numbers of all groups of analyzed cultivable micro…

PAHs associated with the leaves of Quercus ilex L.: Extraction, GC–MS analysis, distribution and sourcesAssessment of air quality in the Palermo (Ita…

2007

Abstract In this study, the leaves of Quercus ilex L. were selected as possible bioaccumulators of polycyclic aromatic hydrocarbons (PAHs). Quercus is an evergreen plant that occurs widely in both urban and rural areas. Several sites (urban roadside, urban, urban park, suburban and rural) in and around Palermo city were investigated. The purpose of this research was to optimize analytical method for quercus leaves, investigate the degree of contamination in the urban area of Palermo by comparing PAH concentration in leaves of quercus from the several sites, establish distribution patterns and relate them to possible sources of PAHs. To this aim, the 16 recommended as priority pollutants by …

Eco-efficiency assessment of wastewater treatment plants using a weighted Russell directional distance model

2016

Abstract Improving the performance of wastewater treatment plants is essential to ensuring their long-term sustainability. Most of the previous studies on this topic have assessed the techno-economic efficiency of wastewater treatment plants and ignored the emission of greenhouse gases. For the first time, the weighted Russell directional distance model was applied to estimate the eco-efficiency of a sample of real wastewater treatment plants. Moreover, this approach allowed an inefficiency score to be obtained for each variable (cost factors, pollutant removal and greenhouse gases) involved in the model. Subsequently, a second stage of analysis was applied to identify factors influencing t…

Leaf Biosorbents for the Removal of Heavy Metals

2018

The presence of heavy metals in waters is a global concern. Among various remediation technologies, biosorption is an attractive and promising process since in many cases, it is fast, selective, and highly efficient. Other advantages, such as applicability for various types of pollutants, simplicity, low cost, ease of operation, and the potential reusability of the adsorbents, make it beneficial. Nowadays, more and more green materials, raw or modified, are inclined to be explored instead of conventional adsorbents, within concept of Green Chemistry. This review focuses on the use of leaves-based biosorbents in raw or modified forms to sequestrate heavy metals from waters and wastewaters.
