An Engineered Supramolecular Pathway for Enhanced Electrochemiluminescence

Advanced Science, EarlyView.
A supramolecular electrochemiluminescent (ECL) system is presented in which cucurbit[7]uril (CB7) is covalently linked to [Ru(bpy)3]2+, forming a recognition‐responsive emitter. Host‒guest preorganization of tri‐n‐propylamine enables intramolecular ECL, boosting intensity by 162% compared to the standard system.

Detection of Cucurbit leaf crumple virus in Florida Cucurbits

Plant Disease, 2008
In October of 2006, yellow straightneck and zucchini squash plants (Cucurbita pepo L.) with crumpled, curled, thickened leaves were found in St. Johns and Marion counties in central Florida, respectively. Both locations had high populations of the whitefly, Bemisia tabaci.

Postharvest Management to Preserve the Nutritional Quality of Vegetables: An Overview Based on Current Research Findings Across the Globe

Future Postharvest and Food, EarlyView.
Postharvest losses in vegetables extend beyond mere quantitative reduction through physical deterioration and spoilage; they encompass substantial qualitative degradation, particularly the deterioration of critical nutritional constituents. Following harvest, vegetables maintain metabolic activity, and when subjected to suboptimal environmental ...

Fine mapping of cucumber downy mildew resistance loci identifies candidate genes linked to ethylene‐associated stomatal defence

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Downy mildew, caused by Pseudoperonospora cubensis, is one of the most destructive diseases affecting cucumber and remains difficult to manage sustainably through fungicide‐dependent control strategies. Although several resistance loci have been reported, many previously mapped regions remain too broad for efficient marker‐assisted ...

Development and deployment of a risk assessment index as a decision‐support tool for managing whitefly‐transmitted viruses affecting squash

Pest Management Science, EarlyView.
A data‐driven framework identified planting date and row cover as dominant drivers of whitefly‐transmitted virus complex (WTVC) risk in squash. Integration into the SquashRx mobile application enables real‐time risk assessment and supports improved decision‐making for integrated pest management.
