Phylogeny and evolution of the epiphytic Rhipsalideae (Cactaceae)
(2012-01-11)
Cactaceae are one of the major floristic components of the New World’s arid as well as seasonally moist tropical regions and at the same time one of the most popular plant families in horticulture. The taxonomic units ...
Quantitative Bestimmung der Permeabilität und Analyse der chemischen Zusammensetzung ausgewählter Kutikula-Mutanten von Arabidopsis thaliana
(2010-12-22)
Die Kutikula bildet die Grenzfläche zwischen den oberirdischen Pflanzenorganen und der Umwelt. Für viele Spezies (z.B. P. laurocerasus) wurden bereits transportphysiologische Untersuchungen mit isolierten Kutikularmembranen ...
Comparative and functional promoter analysis of desiccation-related genes from three closely related plant species differing in desiccation tolerance
(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. ...
Superhydrophobe Oberflächen: Funktionserhaltung durch Regeneration
(2010-03-03)
Viele pflanzliche Oberflächen weisen eine räumliche Mikrostrukturierung auf. Diese Mikrostrukturen sind häufig zusätzlich mit hydrophoben Wachsstrukturen bedeckt. Aufgrund dieser hierarchischen Strukturierung und der Chemie ...
Characterization of drought stress regulator CBF/DREB genes in Hordeum vulgare: Expression analysis in ten different barley cultivars
(2013-07-08)
Improving crop yield under water deficit environments is an urgent task for crop breeding worldwide. Many efforts have been made to identify key regulators of plant drought stress responses. Most of these studies have been ......
The Cytoskeleton of Diatoms: Structural and Genomic Analysis
(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 ...
Identification and molecular characterisation of unknown genes involved in desiccation tolerance mechanisms in the resurrection plant Craterostigma plantagineum
(2014-11-06)
The mechanisms that enable vegetative desiccation tolerance in the resurrection plant Craterostigma plantagineum are not fully understood. Recently, transcriptome data from this plant were obtained thus providing ...
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 ......
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 ......
