Morphological, cultural and ecological characterization of Monilinia spp., pathogens of stone fruit in Serbia [PDF]

open access: yesPesticidi i Fitomedicina, 2020
Different brown rot pathogens cause similar symptoms on fruit, which makes it difficult to differentiate them based only on developed symptoms. Therefore, several methods have been described for accurate identification of Monilinia species.

Quantifying the impact of pesticides on learning and memory in bees

open access: yesJournal of Applied Ecology, 2018
Most insecticides are insect neurotoxins. Evidence is emerging that sublethal doses of these neurotoxins are affecting the learning and memory of both wild and managed bee colonies, exacerbating the negative effects of pesticide exposure and reducing ...

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

open access: yesAdvanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

open access: yesAdvanced Science, EarlyView.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...
