Rooting microbes in plant adaptation: The evolution of locally adaptive plant-microbe interactions
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Repetitive DNA sequences in maize: Possible roles in plant adaptation and transient gene expression
… of repetitive DNA sequences, other than knob, in adaptation of maize to different environmental conditions.

Small non-coding RNA-mediated epigenetic regulation of gene expression and its implications for wheat adaptation to continuous cultivation
… and biotic soil stress factors as well as plant adaptation to long-term monoculture systems. However, the underlying molecular mechanisms have not yet been adequately explained. Against this background, this dissertation presents, in addition to a general introduction (Chapter I) and …

Survival strategies of eelgrass in reduced light
… been widely recognized. Understanding eelgrass plant and meadow responses to light reduction has therefore received significant research interest over the last 30 years, while managers have sought tools to identify critical thresholds for light availability and predict impacts of human-induced …

Physiological Bases and a Novel Genetic Determinant of Water-Use Efficiency (WUE)
… biomass production, relative to wild type (WT) plants. The improved WUE is due to a decrease in transpirational water loss that is correlated with smaller stomata. Transcriptome profiling between <em>taf10</em> and WT plants suggests that mis-regulated auxin-responsive genes in <em>taf10</em> …

Analysis of transcription factors under sulphur deficiency stress
Sulphur, a macronutrient essential for plant growth, is among the most versatile elements in living organisms. Unfortunately, little is known about regulation of sulphate uptake and assimilation by plants. Identification of sulphate signalling processes will allow to control sulphate acquisition …

Alternative splicing in the regulation of the barley circadian clock
… of regulation are conserved in other higher plants, such as barley. By use of a robust in silico analysis and nucleotide sequence of 27 Arabidopsis core clock/clock-associated genes, 21 barley genes were identified, 60% of which are true Arabidopsis orthologues. Most of the barley clock genes …

Macroevolution and phylogenomics in the adaptive radiation of Heliconiini butterflies
… on very recent divergences and on colour pattern adaptation, neglecting deeper timescales and patterns across the rich diversity of the adaptive radiation. The relative importance across adaptive radiations of allopatry, changing ecological pressures, adaptive morphology and introgression promoted …

Analysis of two single trait loci affecting flavonol glycoside accumulations in Arabidopsis thaliana natural variations
Various plant secondary metabolites, including flavonoids, are involved in plant adaptation to different environments. The needs of sessile lifestyle of plants may have increased the variation of enzymes which are required in the modification and/or accumulation of different flavonol derivatives. …

Unraveling the ORE1 regulon in Arabidopsis thaliana : molecular and functional characterization of up- and down-stream components
Leaf senescence is an active process required for plant survival, and it is flexibly controlled, allowing plant adaptation to environmental conditions. Although senescence is largely an age-dependent process, it can be triggered by environmental signals and stresses. Leaf senescence coordinates the …

The role of Gamma-aminobutyric acid and Hydrogen peroxide in cell death in grape berry development
… species (ROS), primarily H2O2, are involved in plant responses to stresses, such as higher temperatures, hypoxia, salinity and water deficit. Many developmental processes, including budburst, flowering, and grape berry ripening, are controlled by H2O2; there is always a balance between the …
