Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Phytoplasma infection renders cranberries more susceptible to above‐ and belowground insect herbivores

Insect Science, EarlyView.
Schematic illustration summarizing the effects of phytoplasma infection on the performance and feeding behavior of above‐ and belowground insect herbivores as well as its effects on shoot and root traits in cranberries. The “+” symbol indicates a positive effect, while the “–” symbol indicates a negative effect. Abstract While phytoplasma infections in

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

arXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

Unlocking agro‐ecosystem sustainability: exploring the bottom‐up effects of microbes, plants, and insect herbivores

Integrative Zoology, EarlyView.
Microorganism‐released metabolites, proteins, or toxins modulate plant‐based targets to regulate physiological processes such as phytohormone and nutrition balance and stress resistance. Microbes that affect plant physiological processes regulate the visual, olfactory, and gustatory cues associated with plants to attract or repel insect herbivores and ...

A transcriptional regulatory network of Rsv3-mediated extreme resistance against Soybean mosaic virus.

PLoS ONE, 2020
Resistance genes are an effective means for disease control in plants. They predominantly function by inducing a hypersensitive reaction, which results in localized cell death restricting pathogen spread. Some resistance genes elicit an atypical response,

A SlMYB78‐regulated bifunctional gene cluster for phenolamide and salicylic acid biosynthesis during tomato domestication, reducing disease resistance

Journal of Integrative Plant Biology, EarlyView.
The tomato transcription factor SlMYB78 controls a key metabolic gene cluster including ENHANCED PSEUDOMONAS SUSCEPTIBILTY 1, encoding a key enzyme that produces disease‐fighting compounds (phenolamides) and immune signals (salicylic acid). During domestication, tomatoes lost a superior variant (SlEPS1HapB), weakening disease resistance; restoring this

Regulatory cross-talks and cascades in rice hormone biosynthesis pathways contribute to stress signaling

Frontiers in Plant Science, 2016
Crosstalk among different hormone signaling pathways play an important role in modulating plant response to both biotic and abiotic stress. Hormone activity is controlled by its bio-availability, which is again influenced by its biosynthesis.

LC/ESI-MS analysis of underivatized amino acids and mass spectrum [PDF]

arXiv, 2016
We report the method of LC/ESI-MS analysis of underivatized amino acids with corresponding mass spectrum and fragmentation patterns. Diagnostic product ions determined by mass spectrometry can support the qualitative identification and quantitative estimation of individual amino acids. Therefore, the optimization of chromatographic separation using the

High‐quality genome of allotetraploid Avena barbata provides insights into the origin and evolution of B subgenome in Avena

Journal of Integrative Plant Biology, EarlyView.
A high‐quality genome sequence of the tetraploid wild oat Avena barbata provides crucial genetic information for the Avena B‐genome, allowing clarification of the evolutionary trajectories of the four subgenomes within Avena and identification of numerous key genes related to environmental adaptability, thus offering valuable resources for oat breeding

Correlations of Amino Acids with Secondary Structure Types: Connection with Amino Acid Structure [PDF]

arXiv, 2005
The correlations of primary and secondary structures were analyzed using proteins with known structure from Protein Data Bank. The correlation values of amino acid type and the eight secondary structure types at distant position were calculated for distances between -25 and 25.
