Chitosan oligosaccharides treatment preserves quality, increases disease resistance, and extends the shelf life of bananas during storage

Food Biomacromolecules, EarlyView.
Chitosan oligosaccharides postharvest treatment effectively preserved quality, enhanced disease resistance, and increased shelf life of fruit. Abstract Different concentrations of chitosan oligosaccharide (COS) (T0: Control, T1: 50 mg/L, T2: 100 mg/L, T3: 250 mg/L, T4: 500 mg/L, and T5: 1000 mg/L COS) were used to investigate the effects of this ...

In Vitro and In Vivo Antifungal Activities of Nine Commercial Essential Oils against Brown Rot in Apples

Horticulturae, 2021
After harvest, numerous plant pathogenic fungi can infect fresh fruits during transit and storage. Although synthetic fungicides are often used to manage postharvest fruit diseases, their application may lead to problems such as the development of ...

Endopolygalacturonase Is Essential for Citrus Black Rot Caused byAlternaria citribut Not Brown Spot Caused byAlternaria alternata [PDF]

Molecular Plant-Microbe Interactions®, 2001
Alternaria citri, the cause of Alternaria black rot, and Alternaria alternata rough lemon pathotype, the cause of Alternaria brown spot, are morphologically indistinguishable pathogens of citrus: one causes rot by macerating tissues and the other causes necrotic spots by producing a host-selective toxin.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...
