MetabolomicsOverexpression of Brassica napus COMT1 in Arabidopsis heightens UV-B-mediated resistance to Plutella xylostella herbivory

UV-B radiation regulates numerous morphogenic, biochemical and physiological responses in plants, and can stimulate some responses typically associated with other abiotic and biotic stimuli, including invertebrate herbivory. Removal of UV-B from the growing environment of various plant species ha...

MetabolomicsFlavonoid pathway intermediates implicate UVR8 in functions beyond canonical UV-B signaling

Plants integrate light signals to regulate development and produce protective compounds such as flavonoids under excessive light stress. While these metabolites protect against light damage, their roles in modulating photoreceptor responses remain unclear. Here we show that naringenin chalcone (N...

TranscriptomicsUV-B regulation of microRNAs in maize
Differential expression of microRNAs was studied in maize leaves after an 8-h-exposure under UV-B light. As a control, plants were kept in the greenhouse in the absence of UV-B 4-week maize plants were grown in the greenhouse in the absence of UV-B. Then, they were divided in two groups. One group w...

TranscriptomicsUV-B-induced gene expression changes in Chlamydomonas reinhardtii
We analysed global gene expression changes in Chlamydomonas reinhardtii in response to 1h UV-B, applied at the same low level that was seen to promote subsequent UV-B stress tolerance, in order to elucidate the transcriptional reprogramming that leads to UV-B acclimation. mRNA profiles generated by ...

ProteomicsConservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha
Ultraviolet-B radiation (UV-B) poses a major challenge to all forms of plant life. The liverwort Marchantia polymorpha (Marchantia) serves as a key model organism to study signaling pathways and to infer their evolution throughout the green lineage. Marchantia expresses key components of UV-B signal...

TranscriptomicsTranscription profiling of Arabidopsis wild type, cop1-4, hy5-1 mutant seedlings exposed to polychromatic radiation
Seven-day-old white-light-grown wild-type, cop1-4 or hy5-1 mutant Arabidopsis seedlings were exposed for fifteen minutes to polychromatic radiation with decreasing short-wave cut-off in the UV range (WG305 = +UV-B, WG327 = -UV-B) and samples were taken 1 h after the onset of irradiation.
