Characterization of the Morphological and Cellular Effects of Arabidopsis thaliana Glutamate Receptor AtGLR3.7 on Plant Growth and Physiology
Weiland, Matthias (2019-01-22)There is a ubiquitous involvement of glutamate receptor-like receptors in all major physiological processes in plants and these proteins have similar operating properties as animal ionotropic glutamate receptors. The aim ... -
Characterization of the transcription factor ANAC058 and its role in suberin regulation
Markus, Katharina (2018-08-28)The hydrophobic polymer suberin is present in plant roots. Its biosynthesis and composition is of importance for tolerance towards environmental stresses. In the model plant Arabidopsis thaliana transcription ... -
Charakterisierung von β-Ketoacyl-CoA-Synthasen aus Arabidopsis thaliana
Briesen, Isabel (2008)Die Familie der β-Ketoacyl-CoA-Synthasen (KCS) katalysieren den entscheidenden Schritt in der Synthese der sehr langkettigen Fettsäuren (VLCFA). Diese stellen die Vorläufermoleküle physiologisch wichtiger Barrieren, wie ... -
The chloroplast calcium sensor protein CAS is part of the STN7/STN8 kinase phosphorylation network and is required for photoacclimation
Cutolo, Edoardo Andrea (2020-03-10)In the present work, the phosphorylation profile of the chloroplast-localized Calcium Sensing Receptor (CAS) from A. thaliana was investigated and it could be shown that CAS is a target of multiple protein kinases ... -
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
Miebach, Andrea (2017-04-20)Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ... -
Comparative and functional promoter analysis of desiccation-related genes from three closely related plant species differing in desiccation tolerance
van den Dries, Niels (2010-03-23)The closely related resurrection plants C. plantagineum and L. brevidens have the rare ability to withstand desiccation of their vegetative tissues. The species L. subracemosa is a close relative of C. plantagineum and L. ... -
Comparative studies of selected stress responsive DREB and ALDH genes in Arabidopsis thaliana, Eutrema salsugineum and Hordeum vulgare
Hou, Quancan (2015-09-02)Drought and salinity are the most severe abiotic stresses limiting agricultural production worldwide. Plant adaptive responses to these stresses involve stress signal perception, signal transduction to cytoplasm and nucleus, ... -
Constraint-based automated reconstruction of grape bunches from 3D range data for high-throughput phenotyping
Mack, Jennifer (2019-10-25)With increasing global population, the resources for agriculture required to feed the growing number of people are becoming scarce. Estimates expect that by 2050, 60 % more food will be necessary. Nowadays, 70 % of fresh ... -
Contribution of phenylpropanoids to the suberin barrier in roots of Arabidopsis thaliana
Millán Hidalgo, Christopher (2019-02-05)The apoplastic polyester suberin forms a barrier in root endodermal and peridermal tissue. Transmission electron microscopy (TEM) displays the lamella-like structure of suberin which is divided into light (electron-translucent) ... -
The Cytoskeleton of Diatoms: Structural and Genomic Analysis
Aumeier, Charlotte (2015-01-08)The cytoskeleton is essential for many cellular functions such as cell motility, the control of cell shape and polarity, meiosis, cytokinesis, intracellular transport as well as endo- and exocytosis. The present study ... -
Deep Phenotyping of disease resistance based on hyperspectral imaging and data mining methods in high throughput
Brugger, Anna (2022-12-12)Hyperspectral imaging for plant phenotyping has become an established research method using the visible to short wave infrared range (400-2500 nm). This allows for the differentiation, identification, and quantification ... -
Determination of spatial and temporal water relations in single leaves and canopies based on thermographic measurements
Albrecht, Hendrik (2016-11-28)Land plants are exposed to an exceptional challenge, because they need to take up CO2 from a dry atmosphere, which induces water loss while taking up CO2. As the leaf water content (LWC) is a result ... -
Dynamics and distribution of ARFB1b and ARFB1c GTPases in N. tabacum plant cells
Renna, Luciana (2009-09-14)Eukaryotic cells are characterized by a complex of endomembranes. The main organelles of this complex are the endoplasmic reticulum, the Golgi apparatus, the trans-Golgi network, the vacuoles, and the plasma membrane. In ... -
Ecological studies of epiphytic bryophytes along altitudinal gradients in Southern Thailand
Chantanaorrapint, Sahut (2010-04-01)Southern Thailand is one of the richest areas in terms of biodiversity. It is a part of the Indo-Burma and Sundaland biodiversity hot spots. It also included the transition zone between Indo-Chinese and Malesian floristic ... -
Effect of salt stress on apoplastic barriers in roots and leaves of two barley species
Thangamani, Priya Dharshini (2022-05-06)In this study, the responses of 12 d old cultivated barley (Hordeum vulgare L. spp.vulgare) cv Scarlett and a wild accession (Hordeum vulgare spp. sponataneum) from Pakistan (ICB181243) to salt stress of ... -
Effects of drought and the role of auxin on barley stamen maturation
Lange, Richard Johannes (2023-07-04)Drought is a major abiotic stress that reduces crop yields all over the world. Climate change is predicted to increase the frequency and intensity of future drought events. Concomitantly, the increasing world population ... -
Effects of fragmentation and degradation of an afrotropical rain forest on the diversity structure of leaf beetle communities (Coleoptera, Chrysomelidae)
Freund, Wolfram M. (2005)East African forests are particularly diverse and endangered but are still little-known ecosystems. With an increase of the human population in East Africa throughout the last decades, the pressure on biodiversity largely ... -
