Unexpected chromosomal DNA transfer from Agrobacterium tumefaciens to plant cells: mechanisms and solutions
(2015-01-09)
The soil bacterium and plant pathogen Agrobacterium tumefaciens has the ability to transfer a defined part of its genome, the so called transferred DNA (T-DNA), to plant cells. This transfer has been successfully ...
Promoter regulation of the Craterostigma plantagineum Cp LEA-like 11-24 gene and functional characterization of its transcription factor (CpbZIP1)
(2014-08-26)
The resurrection plant Craterostigma plantagineum, a member of Linderniaceae family, is distributed in areas with variable water availability in Southern Africa. Two closely related species, L. brevidens which is endemic ......
Biosynthese und Analytik von Sesquiterpenen in Weinbeeren (Vitis vinifera)
(2016-05-17)
Mit dem Sesquiterpen Rotundon wurde 2008 erstmals ein Sesquiterpen als Schlüsselaromastoff im Wein identifiziert. Bis dato lagen nur wenige Informationen zu Sesquiterpenen in Vitis vinifera vor. Ziel dieser Arbeit war es ......
Synaptotagmin 1 and Synaptic Vesicle Protein 2-like in Arabidopsis
(2016-06-07)
The process of synaptic transmission at neuronal synapses is mediated by synaptic vesicle cycle. Synaptotagmins (SYTs) and Synaptic Vesicle Protein 2 (SV2), widely studied in animals since the 1990s, are important synaptic ...
Extracellular ATP Signaling is Linked to Endocytic Vesicle Recycling in Root Apex
(2016-06-09)
Plants are sessile organisms, the roots of which exudate a large number of chemical compounds into the rhizosphere that contain several chemicals and microbes. It is known that at the root apex, the transition zone is ...
Global change effects on ecosystem species composition, functions and services of West Africa’s Sudanian savannas
(2016-12-09)
Savanna ecosystems cover an eighth of the world's land surface and are of immense ecological and economic importance. Ecologically, they help regulate climate, air quality, water quality, and soil erosion. Economically, ...
Determination of spatial and temporal water relations in single leaves and canopies based on thermographic measurements
(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 ......
Die Rolle von DGD1 in dem eukaryotischen und prokaryotischen Galaktolipid-Metabolismus von Arabidopsis thaliana
(2016-12-20)
Die Galaktolipide Monogalaktosyldiacylglycerin (MGDG) und Digalaktosyldiacylglycerin (DGDG) sind die häufigsten Membranlipide der Chloroplasten. Die Biosynthese von DGDG erfolgt hauptsächlich durch die Glykosyltransferase ......
A forward genetic approach to isolate Arabidopsis mutants altered in the regulation of the ALDH7B4 gene
(2016-09-30)
The ALDH7B4 gene is a member of the ALDH super gene family which is known to be involved in stress tolerance, but the regulation of ALDHs was unknown. In the current studies, a forward genetic approach was used to propose ......
Potential of Complementary Methods for the Authentication of Herbal Substances and their Mixtures
(2015-10-22)
Herbal substances and preparations thereof play an important role in healthcare systems worldwide. An essential prerequisite for the safe and effective use of herbal medicines is the unequivocal identification of the plant ...
