Effects of an invasive plant species, giant goldenrod (Solidago gigantea) on pollinator communities
2018
Invasive plant species can have an effect on native plant and related pollinator insect communities both in anthropogenically disturbed and semi-natural habitats. Due to the dominance of invasive plant species, the impoverished vegetation often results in a decline of native pollinator diversity. Furthermore, invasive species may have a negative effect on flower-visitation of the native wild plant or crop species. We studied the effect of giant goldenrod (Solidago gigantea), a common insect-pollinated invasive plant species in Hungary, on bee (Hymenoptera: Apoidea) and hoverfly (Diptera: Syrphidae) communities. We compared 10 invaded (relative cover of S. gigantea >50%) with 10 uninvaded…
Manipulating below ground diversity for above ground diversity: application of fungi for vegetation restoration
2018
The loss and fragmentation of habitats is one of the main drivers of deteriorating ecosystem functioning and services. This has induced a growing need for conservation and increasingly more – restoration. A central part of land-ecosystems is soil biota with arbuscular mycorrhizal (AM) fungi being a key constituent. As ubiquitous plant symbionts, AM fungi have a global impact on carbon sequestration and nutrient cycling, soil formation, erosion and leaching processes, therefore influencing all spheres of earth. In soils where disturbance has lead to the loss of soil cover or a drastic change in plant community composition, the absence of suitable AM fungal symbionts can lead to slow post-res…
Rapid cell growth regulation in Arabidopsis
2021
Plant motions occur across a wide spectrum of timescales, ranging from seed dispersal through bursting (milliseconds) and stomatal opening (minutes) to long-term adaptation of gross architecture. Relatively fast motions include water-driven growth as exemplified by root cell expansion under abiotic/biotic stresses or during gravitropism. A showcase is a root growth inhibition in 30 seconds triggered by the phytohormone auxin. However, the cellular and molecular mechanisms are still largely unknown. This thesis covers the studies about this topic as follows. By taking advantage of microfluidics combined with live imaging, pharmaceutical tools, and transgenic lines, we examined the kinetics o…
Isolasi dan Identifikasi Cendawan Filoplan yang Berpotensi Sebagai Agensia Pengendali Cendawan Patogen Phytopthora palmivora pada Tanaman Kakao
2018
Cocoa (Theobroma cacao L.) plantations �development in Indonesia have been made effort today almost in every areas, but not improved yield. An inhibitor factor is pest and disease invasion. Controling of cocoa pod rot disease caused by Phytophthora palmivora in common suggestion is used of sintetic fingicide, but it has hazard effect to environment, animals and human health, thus today, friendly controling tecnology by used of antagonistic microorganism is being developed. Common Antagonistic microorganism used were soil-inhabitant (rhizosphere). It supposed that, there were plant�s surface-inhahabitant (phyloplen) fungi which potentially as antagonist agent to P. palmivora. This research w…
Status Ekonomi Jamur Patogen Tomat di Manokwari akibat Penggunaan Varietas Introduksi Baru
2018
Economic status of fungi pathogenic on tomato was affected by introducing of new varieties of tomato in Manokwari. Observation on Amelia, Ratna and Permata, was found that fungus is responsible in a leaf disease, wilting, and fruit rot. Leaf disease was caused by Cercospora sp. And Corynespora sp. The fungus which causing a leaf disease in this observation was one of major disesase with disease intensity is 20 to 80 percent. Other disease such as wilt caused by Fusarium sp. and Sclerotinia sp.; and fruit rot caused by Colletotrichum sp. become a minor disease with disease intensity is 0 � 2 percent.
Micropropagation from inflorescence stems of the Spanish endemic plant Centaurea paui Loscos ex Willk. (Compositae)
1999
Tissue culture techniques have been established as a useful approach for ex situ conservation of rare, endemic or threatened plant species. This report describes the micropropagation of Centaurea paui Loscos ex Willk (Compositae), an extremely endangered plant species endemic to the Valencia Community (eastern Spain), as a conservation measure which does not cause damage to the wild plants used as explant source. Inflorescence nodal segments of C. paui were selected as explants for in vitro establishment. The best rate of shoot proliferation was obtained on Murashige and Skoog (MS) mineral medium supplemented with 0.5 mg/l 6-benzyladenine or with 2 mg/l kinetin. Maximum shoot elongation was…

Microbial community composition but not diversity changes along succession in arctic sand dunes
2017
The generality of increasing diversity of fungi and bacteria across arctic sand dune succession was tested. Microbial communities were examined by high-throughput sequencing of 16S rRNA genes (bacteria) and internal transcribed spacer (ITS) regions (fungi). We studied four microbial compartments (inside leaf, inside root, rhizosphere and bulk soil) and characterized microbes associated with a single plant species (Deschampsia flexuosa) across two sand dune successional stages (early and late). Bacterial richness increased across succession in bulk soil and leaf endosphere. In contrast, soil fungal richness remained constant while root endosphere fungal richness increased across succession. …
MAHONIA AQUIFOLIUM AS A PROMISING RAW MATERIAL FOR THE FOOD INDUSTRY
2017
The development of the food industry leads to the expansion of the range of processed raw materials. Mahonia aquifolium today can be attributed to the non-traditional agricultural plants. However, the analysis of the chemical composition of the fruits showed that they contain significant amount of carbohydrates, vitamin C, various minerals, which recommend it for a wider use in the diet. Also due to the presence in the fruits of Mahonia aquifolium anthocyanins can extend of the use as raw material for natural anthocyanin dyes obtaining.
Influence of Cognettia sphagnetorum (Enchytraeidae) on birch growth and microbial activity, composition and biomass in soil with or without wood ash
2001
In this laboratory study using microcosms with seedlings of silver birch (Betula pendula), we explored whether Cognettia sphagnetorum (Enchytraeidae) can retain its important role of accelerating decomposition processes in soils and stimulating primary production under disturbance. We established systems with or without wood ash amendment (first-order disturbance) in the soil, either in the presence or absence of C. sphagnetorum. To test whether the systems treated with wood ash are more sensitive to an additional disturbance than the ash-free systems, the microcosms were later on disturbed by drought. To determine the influence of two disturbances on the enchytraeids and populations of oth…
