3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Sensitivity Analysis of a Proposed Model for Removal Efficiency of Trihalomethanes (THMs) Using Spray Aeration [PDF]

open access: yes, 2013
Trihalomethanes (THMs) form in drinking water treatment systems as a byproduct of chlorination and are problematic from a public health perspective due to their carcinogenic potential and their potential for additional formation throughout distribution ...

Bacillus velezensis 83 protects Arabidopsis thaliana against Botrytis cinerea by triggering JA‐, and SA‐dependent induced systemic resistance

open access: yesPest Management Science, Volume 82, Issue 3, Page 2532-2540, March 2026.
B. velezensis 83 protects the plant against B. cinerea, accumulating acetoin and activating jasmonic acid‐ and salicylic acid‐mediated defense responses. Abstract BACKGROUND Modern agriculture is based on the application of synthetic agrochemicals to control multiple abiotic and biotic stresses.

Use of chemical markers in Antarctic ecosystem studies of Demaria Mount

open access: yesУкраїнський антарктичний журнал, 2020
Research is devoted to using chemical markers for studying and description of ecosystems. Photosynthetic pigments – carotenoids and chlorophylls, and soil polymers – humic, fulvic acids and their salts, were used as chemical markers. Correlations between

Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil [PDF]

open access: yes, 2007
Molibility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from oils to surface waters. To study the sorption an mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM ...

Ozonated irrigation in vineyards: limited effects on soil bacterial and fungal microbiota

open access: yesPest Management Science, Volume 82, Issue 3, Page 2746-2757, March 2026.
Irrigation with ozonated water caused slight changes in bacterial composition but did not significantly affect microbial diversity, beneficial microbes (plant growth‐promoting bacteria, arbuscular mycorrhizal fungi), or grapevine trunk disease‐related pathogens.

Water-Stable Aggregates and Associated Carbon in a Subtropical Rice Soil Under Variable Tillage

open access: yesRevista Brasileira de Ciência do Solo, 2016
Tillage systems can influence C sequestration by changing aggregate formation and C distribution within the aggregate. This study was undertaken to explore the impact of no-tillage without straw (NT-S) and with straw (NT+S), and moldboard plow without ...
