Functional Integration of Floral Plant Traits: Shape and Symmetry, Optical Signal, Reward and Reproduction in the Angiosperm Flower
(2020-05-12)
Pollination syndromes represent groups of floral phenotypes that have originated and diversified in interaction with biotic and abiotic pollen vectors. Plant trait pattern that constitute respective syndromes have been ...
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 ......
Proteins under the control of phospholipase D in Arabidopsis thaliana
(2016-05-12)
The phosphoproteome of the pldα1-mutant lacks a protein that is abundantly expressed in the wild type and has been identified as the unknown protein At5g39570.1. The characterization of this protein in the context of ...
The mechanisms of stress memory responses and translational regulation during dehydration and rehydration in the resurrection plant Craterostigma plantagineum
(2020-05-25)
Dehydration stress is one of the major environmental factors affecting the survival rate and productivity of plants. Currently, many dehydration-induced genes and some dehydration-related protective mechanisms desiccation ......
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(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 ...
Biogeomorphic dynamics in the Turtmann glacier forefield, Switzerland
(2017-05-19)
Worldwide, glacier retreat enlarges glacier foreland areas, which are characterized by pronounced geomorphic and ecologic dynamics. Feedbacks between these dynamics are believed to drive glacier foreland landscape development, ...
Systematics, Taxonomy, and Evolution of Urtica L. (Urticaceae)
(2017-04-25)
The systematics of Urtica have puzzled scientists for the past 200 years and no single comprehensive attempt at understanding infrageneric relationships has been published in the past, nor have species delimitations ...
Evaluating the phylogenetic structure and microstructural evolution of organellar markers from both compartments in the reconstruction of a carboniferous radiation (mosses)
(2017-09-12)
In the reconstruction of the plant tree of life, sequence data from the plastid genome is currently favored as it contains a mixture of coding and noncoding regions, spanning different patterns of substitution rates and ...
