Higher‐Level Structural Classification of Pseudomonas Cyclic Lipopeptides through Their Bioactive Conformation

open access: yesAdvanced Science, EarlyView.
Solution structures of a series of cyclic lipodepsipeptides from Pseudomonas reveal that these specialized metabolites adopt left‐handed alpha helical conformations of only two types, being either ‘stapled’ or ‘catch‐pole’ helix. The particular modular distribution of the biosynthetic gene clusters is found to determine the extent of their conserved ...

High risk pesticides in sugar beet protection [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2006
According to traits of pesticides permitted to use in sugar beet (oral percutaneus and inhalation toxicity, toxicity to wildlife, bees and aquatic organisms, re-entry interval, maximum number of treatments, effects on reproduction) do not present health ...

Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

open access: yesAdvanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.

Comparative evaluation of some commercial spray-applied insecticides as control method against Blatta orientalis

open access: yesЖивотновъдни науки
Cockroaches are globally distributed pests with high epidemic importance. Their role as spreaders of many infectious and parasitic diseases in animals and humans determines disinsection as the main anti-epidemic measure.

First experiences in the application of biopreparations against the cherry fruit fly in Southern Russia in 2007 [PDF]

open access: yes, 2008
On the Russian market there are no currently registered biological preparations for the control of Rhagoletis cerasi (cherry fruit fly, CFF), and therefore the effects of natural products against this pest were studied.

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

open access: yesAdvanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

Variation in the susceptibility of Anopheles gambiae to botanicals across a metropolitan region of Nigeria [PDF]

open access: yes, 2019
Pesticide resistance is normally associated with genetic changes, resulting in varied responses to insecticides between different populations. There is little evidence of resistance to plant allelochemicals; it is likely that their efficacy varies ...
