We assessed the individual and combined effects of chemically mimicked insect herbivory, warming, and elevation on dwarf birch (<i>Betula glandulosa</i>) VOC emissions in high-latitude tundra ecosystems in Narsarsuaq, South Greenland. We hypothesized that VOC emissions and compositions would respond synergistically to warming and herbivory, with the magnitude differing between elevations. Warming increased emissions of green leaf volatiles (GLVs) and isoprene. Herbivory increased the homoterpene, (E)-4,8-dimethyl-1,3,7-nonatriene, emissions, and the response was stronger at high elevation. Warming and herbivory had synergistic effects on GLV emissions. Dwarf birch emitted VOCs at similar rates at both elevations, but the VOC blends differed between elevations. Several herbivory-associated VOC groups did not respond to herbivory. Harsher abiotic conditions at high elevations might not limit VOC emissions from dwarf birch, and high-elevation plants might be better at herbivory defense than assumed. The complexity of VOC responses to experimental warming, elevation, and herbivory are challenging our understanding and predictions of future VOC emissions from dwarf birch-dominated ecosystems.</p>","PeriodicalId":74457,"journal":{"name":"Plant-environment interactions (Hoboken, N.J.)","volume":"4 1","pages":"23-35"},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10168049/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9645610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PEI is still a young journal, although we have now published two full volumes (in 2021 and 2022). Over these past 2 years, we have recognized that some submitted studies may not be focused primarily on a research question or hypothesis, but instead they may be describing the invention, development, or improvement of methodological approaches or equipment that can be used to better understand how plants interact with the abiotic and biotic environment. In response to this, in 2023, we will be launching Methods and Techniques as an article category that the authors can choose on submission of their manuscripts. The guidelines for preparation of manuscripts to be considered under Methods and Techniques will be the same as those for research articles, with the same limit on total number of figures and tables combined (maximum of 10). However, the structure of Methods and Techniques does not have to adhere to the traditional Introduction— Methods— Results— Discussion format of research articles. Manuscripts submitted under this new category should still have an abstract and will need to provide evidence that the new methods/ equipment work as intended. This evidence can involve comparison with other established approaches, presentation of statistical analyses that quantify precision, accuracy and/or repeatability, and visual aids, depending on the method and its applications. In the interest of transparency and reproducible sound science, we also ask that where new protocols, workflows. or equipment are described, all details are made available at submission that would be needed by a third party to reproduce the method. This may include design plans, programming code, or detailed lab protocols, and these details can be submitted as supplementary materials for review. Finally, as with all other article categories in our journal, Methods and Techniques submissions need to involve interactions between plants and their abiotic or biotic environment for us to consider the submission for publication. As an openaccess journal, PEI is an ideal venue for publication of studies introducing new or improved methodologies, because there is great potential for those new approaches to reach and be used by a wide range of plant and environmental scientists across the globe. We look forward to receiving and reading your Methods and Techniques submissions soon.","PeriodicalId":74457,"journal":{"name":"Plant-environment interactions (Hoboken, N.J.)","volume":"4 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10168055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9645607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bacterial communities displayed spatial structure in two plots at one location based on a significant increase in community dissimilarity with increasing spatial distance. Null model analyses identified a lack of phylogenetic turnover among bacterial communities in all plots, but a greater frequency of dispersal limitation in the two plots where spatial structure was also observed.

Here we report on the characterization of contrasting vegetative heat tolerance in two UK bread wheat varieties. Under chronic heat stress, the heat-tolerant cultivar Cadenza produced an excessive number of tillers which translated into more spikes and higher grain yield compared to heat-sensitive Paragon. RNAseq and metabolomics analyses revealed that over 5000 genotype-specific genes were differentially expressed, including photosynthesis-related genes, which might explain the observed ability of Cadenza to maintain photosynthetic rate under heat stress. Around 400 genes showed a similar heat-response in both genotypes. Only 71 genes showed a genotype × temperature interaction. As well as known heat-responsive genes such as heat shock proteins (HSPs), several genes that have not been previously linked to the heat response, particularly in wheat, have been identified, including dehydrins, ankyrin-repeat protein-encoding genes, and lipases. Contrary to primary metabolites, secondary metabolites showed a highly differentiated heat response and genotypic differences. These included benzoxazinoid (DIBOA, DIMBOA), and phenylpropanoids and flavonoids with known radical scavenging capacity, which was assessed via the DPPH assay. The most highly heat-induced metabolite was (glycosylated) propanediol, which is widely used in industry as an anti-freeze.
