Mechanisms of selective translational control under short-term high light stress
… stimuli are subject of intensive research. Light in this context takes a special role, since it represents the ultimate source of energy for autotrophic growth. In addition, light-driven photosynthesis is inevitably linked to oxidative stress in a stressful environment, so suitable coping …

Investigation of mRNA Expression of Early Light Inducible Protein (ELIP) under High Light Stress <em>Arabidopsis thaliana</em>.
<p>Plants absorb light for photosynthesis, but not all is used. Excess light energy may lead to photoinhibition of photosynthesis and irreversible photooxidative damage. Plants have evolved mechanisms for energy dissipation under high light stress. One such response may involve production of …

The Photoprotective Role of Anthocyanin Pigments in Leaf Tissues
… anthocyanins effectively reduce internal light within the leaf, which may be beneficial under high-light stress conditions. However, pigment patterns in natural systems often appear inconsistent with a photoprotective function (e.g. anthocyanins in abaxial leaf surfaces), and their absence …

From cradle to grave: The influence of mRNA metabolism on plant stress responses
… and consequently a key regulatory target. During stress, control of mRNA metabolism (and downstream protein production) takes on particular importance due to the energy constraints imposed on the cell. However, the fate of stress-induced mRNAs, particularly with regard to RNA degradation, remains …

The Ancestry and Function of Cytochrome c6A
… c6 found in eukaryotic green algae and higher plants. However it is thought to perform a different function from cytochrome c6. Two current hypotheses exist for this function: that cytochrome c6A acts as a ‘safety valve’, providing an alternative path for electron flow through the …

Functional analysis of MYB112 transcription factor in the model plant Arabidopsis thaliana
… environmental parameters including salinity or high light stress may trigger anthocyanin accumulation. In contrast to several other MYB TFs affecting anthocyanin biosynthesis pathway genes, MYB112 expression is not controlled by nitrogen limitation, or carbon excess, but rather is stimulated by …

Transcriptomic study of evolution and gene expression in diploid and allotetraploid glycine subgenus glycine
… in the subgenus Glycine following exposure to high light stress. We compared the overall expression of homeologous gene pairs (duplicated genes due to whole genome duplication) with the expression of its homologous genes in its diploid progenitors. We observed that a majority of the genes …

The effect of non-glaucousness, as conferred by Inhibitor of Wax 1, on physiology and yield of UK Wheat
… years. A long-term shade trial reducing incoming light by 40 and 60% was also carried out in 2014. Yield, and various physiological components including water use efficiency (WUE) and spectral properties, were measured. Iw1 reduced flag leaf photosynthetically active radiation (PAR) reflectance by …

From the ice to the open ocean : threats to phytoplankton productivity in the Antarctic marine ecosystem from a changing climate
… this thesis explores the processes of light acclimation, photoprotection and photoinhibition in Antarctic microalgae under different environmental stressors, comparing photophysiological responses of species known to inhabit the sea-ice, meltwater and pelagic regions of Antarctic …
