Transcriptome and metabolome analyses revealed that narrowband 280 and 310 nm UV-B induce distinctive responses in Arabidopsis

Scientific Reports, 2022
In plants, the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8) perceives UV-B and induces UV-B responses. UVR8 absorbs a range of UV-B (260–335 nm). However, the responsiveness of plants to each UV-B wavelength has not been intensively studied so far ...

UV-B photoreceptor-mediated protection of the photosynthetic machinery in Chlamydomonas reinhardtii.

, 2016
International audienceLife on earth is dependent on the photosynthetic conversion of light energy into chemical energy. However, absorption of excess sunlight can damage the photosynthetic machinery and limit photosynthetic activity, thereby affecting ...

Plastic response in Pinus spp., determining the temporal window of response and species-level variation of UV-B absorbing compounds to short-term variation in UV-B radiation [PDF]

, 2017
The total amount of ultraviolet radiation (UV-B wavelength = 280–315 nm) reaching the Earth’ surface has probably experienced large changes throughout Earth’s history.

Response of barley and pea crops to supplementary UV-B radiation. [PDF]

, 1999
Four cultivars of winter barley (Hordeum vulgare L.) and two cultivars of combining pea (Pisum sativum L.) were grown in the field in the UK (52°N) and irradiated under banks of UV-B lamps in 1994/95 (barley) and 1996 (pea).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Detecting and modeling topography‐induced differences in plant productivity across a grassland ecosystem gradient

Ecosphere
Understanding spatial variation in grassland productivity is critical for ecological modeling and management. The Great Plains of North America, a vast grassland region east of the Rocky Mountains, exhibits strong gradients in aboveground net primary ...

Cell compartmentation of UV-absorbing compounds in two aquatic mosses under enhanced UV-B [PDF]

, 2012
The effects of enhanced UV-B radiation on UV-absorbing compounds (UVAC), the maximum quantum yield of photosystem II (Fv/Fm), DNA integrity, and the sclerophylly index, were analyzed in the mosses Bryum pseudotriquetrum and Fontinalis antipyretica.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
