Using long-term data from a whole ecosystem warming experiment to identify best spring and autumn phenology models. [PDF]

Plant Environ Interact, 2023
Here, we leverage multiyear interannual variability in climate with an experimental whole‐ecosystem warming approach to identify model structures that are best suited to predicting phenological changes and future climate scenarios. In spring, seven equally best‐performing models for Larix utilized the accumulation of growing degree days as a common ...

Perturbation of nuclear–cytosolic shuttling of Rx1 compromises extreme resistance and translational arrest of potato virus X transcripts

The Plant Journal, Volume 106, Issue 2, Page 468-479, April 2021., 2021
Significance Statement It is unknown how antiviral immunity is conferred in the case of extreme resistance. We show that extreme resistance correlates with a translational arrest of viral transcripts and can be uncoupled from the hypersensitive response, which was observed to not be required for viral immunity.

A highly differentiated region of wheat chromosome 7AL encodes a Pm1a immune receptor that recognizes its corresponding AvrPm1a effector from Blumeria graminis

New Phytologist, Volume 229, Issue 5, Page 2812-2826, March 2021., 2021
Summary Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination. A nucleotide‐binding, leucine‐rich repeat (NLR) immune receptor gene was isolated using mutagenesis and R gene enrichment sequencing ...

Nonribosomal Peptides Produced by Minimal and Engineered Synthetases with Terminal Reductase Domains

ChemBioChem, Volume 21, Issue 19, Page 2750-2754, October 1, 2020., 2020
Peptide aldehyde production: An aldehyde‐releasing reductase (R) domain has been identified as part of a minimal nonribosomal peptide synthetase (NRPS) in X. indica. We also show that the R domain from the tilivalline‐producing NRPS can be used in engineered synthetases to introduce an aldehyde group and subsequently produce natural and unnatural ...

Partial Polarization in Interfered Plasmon Fields

Journal of Nanomaterials, Volume 2014, Issue 1, 2014., 2014
We describe the polarization features for plasmon fields generated by the interference between two elemental surface plasmon modes, obtaining a set of Stokes parameters which allows establishing a parallelism with the traditional polarization model. With the analysis presented, we find the corresponding coherence matrix for plasmon fields incorporating

Sliding‐Mode Control of a Dc/Dc Postfilter for Ripple Reduction and Efficiency Improvement in POL Applications

Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013
This paper proposes an active postfilter based on two Buck converters, connected in parallel, operating in complementary interleaving. In such a configuration the ripple in the load current could be virtually eliminated to improve the power quality in comparison with classical Point‐Of‐Load (POL) regulators based on a single Buck converter.

Using LanM Enzymes to Modify Glucagon‐Like Peptides 1 and 2 in E.coli

ChemBioChem, Volume 25, Issue 13, July 2, 2024.
Peptides serve as important drugs but suffer from short lifetimes in circulation. The lifetime can be extended by installing chemical modifications, but these can be expensive to incorporate. We show that production, as well as modifications with non‐proteogenic amino acids, can be accomplished in E.coli by exploiting enzymes involved in the ...

Conquering new grounds: plant organellar C‐to‐U RNA editing factors can be functional in the plant cytosol

The Plant Journal, Volume 119, Issue 2, Page 895-915, July 2024.
Significance Statement We show that PPR‐type organelle RNA editing factors can principally also function in the plant cytosol but that their lack of targeting specificity likely restricts their occurrence in nature to chloroplasts and mitochondria. Our new approach of induced cytosolic expression will allow to much better characterize the RNA‐targeting

Phenology of Photosynthesis in Winter‐Dormant Temperate and Boreal Forests: Long‐Term Observations From Flux Towers and Quantitative Evaluation of Phenology Models

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 5, May 2024.
Abstract We examined the seasonality of photosynthesis in 46 evergreen needleleaf (evergreen needleleaf forests (ENF)) and deciduous broadleaf (deciduous broadleaf forests (DBF)) forests across North America and Eurasia. We quantified the onset and end (StartGPP and EndGPP) of photosynthesis in spring and autumn based on the response of net ecosystem ...
