First Report of Cyrtanthus Elatus Virus A Infection in Daffodils in Korea.

In Korea, the limited production and distribution of virus-free bulbs necessitate reliance on imported bulbs for daffodil () cultivation. Three viruses have been reported in daffodils in Korea, and quarantine measures target six viruses in imported bulbs (Kim and Jeong 2024; Kim et al. 2024).

Investigation of Tissue-Specific Distribution and Genetic Variation of Alfalfa Mosaic Virus and Chinese Artichoke Mosaic Virus in Chinese Artichoke (Stachys affinis miq.).

The Chinese artichoke (Stachys affinis syn. S. sieboldii) is a widely cultivated crop, and its rhizome is used as a medicinal vegetable.

The N-Terminal Region of Cucumber Mosaic Virus 2a Protein Is Involved in the Systemic Infection in .

belongs to the family and is used as both an oilseed and vegetable crop. As only a few studies have reported on the cucumber mosaic virus (CMV) in , we conducted this study to provide a basic understanding of the and CMV interactions. -infecting CMV (CMV-Co6) and non-infecting CMV (CMV-Rs1) were used.

Redox Potential Tuning of s-Tetrazine by Substitution of Electron-Withdrawing/Donating Groups for Organic Electrode Materials.

Herein, we tune the redox potential of 3,6-diphenyl-1,2,4,5-tetrazine (DPT) by introducing various electron-donating/withdrawing groups (methoxy, t-butyl, H, F, and trifluoromethyl) into its two peripheral benzene rings for use as electrode material in a Li-ion cell. By both the theoretical DFT calculations and the practical cyclic voltammetry (CV) measurements, it is shown that the redox potentials (E) of the 1,2,4,5-tetrazines (s-tetrazines) have a strong correlation with the Hammett constant of the substituents. In Li-ion coin cells, the discharge voltages of the s-tetrazine electrodes are successfully tuned depending on the electron-donating/withdrawing capabilities of the substituents.

Mellitic Triimides Showing Three One-Electron Redox Reactions with Increased Redox Potential as New Electrode Materials for Li-Ion Batteries.

The mellitic triimide (MTI) bearing three imide groups on a benzene core with C3 symmetry is proposed as a new building block for organic electrode materials in lithium-ion batteries. MTI was anticipated to deliver a higher theoretical specific capacity of up to 282 mAh g with increased reduction potentials compared with the well-known pyromellitic diimide building block bearing two imide groups because the additional imide group can accept one more electron and provide an electron-withdrawing effect. A model compound, ethyl-substituted mellitic triimide (ETTI), shows three well distinguished and reversible one-electron redox reactions at -0.

s-Tetrazines as a New Electrode-Active Material for Secondary Batteries.

Because of the limitations of conventional metal-oxide-based electrodes, studies on organic redox-active materials as alternative electrodes for secondary batteries are emerging. However, reported organic electrode materials are still limited to a few kinds of organic redox groups. Therefore, the development of new redox-active groups for high-performance electrode materials is indispensable.
