Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

Advanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

Biological activity of coumarin derivatives – a review

Croatian Journal of Food Science and Technology, 2011
Coumarin derivatives are wide spread in nature and found in many plants, fruits and vegetables. They show a broad spectrum of biological activities, but the use of coumarin is restricted by law and its maximal allowed concentration in foodstuff is ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

American Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Microwave Assisted Heterocyclization: A Rapid and Efficient Synthesis and Antibacterial Activity of Novel Thiazolidinones

E-Journal of Chemistry, 2004
As a target to synthesize various Thiazolidinone derivatives, 2-Amino-4-(coumarin-3-yl)-thiazole has been prepared by the reactions of 3-Bromo acetyl coumarin with thiourea. 3-Bromo acetyl coumarin was prepared from 3-Acetyl coumarin.

Influence of Polarity of Solvents on the Spectral Properties of Bichromophoric Coumarins

Molecules, 2010
Absorption and fluorescence spectra of bichromophoric coumarins were investigated in different solvents and in polymer matrices. These bichromophoric coumarins were composed of a coumarin dimethylamino-substituted at position 7 or unsubstituted coumarin ...

New natural deep eutectic solvents based on aromatic organic acids

Green Chemistry Letters and Reviews, 2021
It is imminent to explore new types of starting materials for natural deep eutectic solvents (NADESs). Herein, a series of natural aromatic organic acids as the hydrogen bond donor (HBD) and coumarin as the model hydrogen bond acceptor (HBA) were used to
