Project description: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 has been found to increase their susceptibility to consumption by invertebrate pests, however, to date, little research has been conducted to investigate the effects of UV-B on crop susceptibility to field pests. Here, we report findings from a multi-omic and genetic-based study investigating the mechanisms of UV-B-stimulated resistance of the crop, Brassica napus (oilseed rape), to herbivory from an economically important lepidopteran specialist of the Brassicaceae, Plutella xylostella (diamondback moth). The UV-B photoreceptor, UV RESISTANCE LOCUS 8 (UVR8), was not found to mediate resistance to this pest. RNA-Seq and untargeted metabolomics identified components of the sinapate/lignin biosynthetic pathway that were similarly regulated by UV-B and herbivory. Arabidopsis mutants in genes encoding two enzymes in the sinapate/lignin biosynthetic pathway, CAFFEATE O-METHYLTRANSFERASE 1 (COMT1) and ELICITOR-ACTIVATED GENE 3-2 (ELI3-2), retained UV-B-mediated resistance to P. xylostella herbivory. However, overexpression of B. napus COMT1 in Arabidopsis further reduced plant susceptibility to P. xylostella herbivory in a UV-B-dependent manner. These findings demonstrate that overexpression of a component of the sinapate/lignin biosynthetic pathway in a member of the Brassicaceae can enhance UV-B-stimulated resistance to herbivory from P. xylostella.

Project description:ra10-01_laccases; laccase mutations. We demonstrated that laccases are involved in lignin polymerisation. Mutants have already been tested on microarrays and there is few differences compared to wild-type. The laccase mutation seems surgical. We possess a new double mutant, called snips, with a semi-dwarf phenotype, and we want to determine its profile.

Project description:UV radiation is a ubiquitous component of solar radiation that affects plant growth and development. Analysis of natural variation in response to UV radiation revealed significant differences among natural accessions of Arabidopsis thaliana. However, the genetic basis of this is to a large extent unknown. Here, we analyzed the response of Arabidopsis accessions to UV radiation stress by performing RNA-sequencing of three UV sensitive and three UV resistant accessions. The genome-wide transcriptional analysis revealed a large number of genes significantly up- or down-regulated only in sensitive or only in resistant accessions, respectively. Mutant analysis of few selected candidate genes suggested by the RNA-sequencing results indicate a connection between UV radiation stress and plant-pathogen-like defense responses.
