A systematic representation of crop rotations. [PDF]

open access: yes, 2008
Crop rotations are allocations by growers of crop types to specific fields through time. This paper aims at presenting (i) a systematic and rigorous mathematical representation of crops rotations; and (ii) a concise mathematical framework to model ...

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

open access: yesFEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Cholinesterase activity in blood and pesticide presence in sweat as biomarkers of children`s environmental exposure to crop protection chemicals

open access: yesAnnals of Agricultural and Environmental Medicine, 2015
Introduction On the contrary to the adult population exposed to pesticides, mostly on occupational basis, rural children are mostly exposed to pesticides deposited in the environment.

Effect of plant growth regulator used with adjuvants in winter wheat (Triticum aestivum L.) [PDF]

open access: yesJournal of Plant Protection Research
Crop yields depend not only on genetic traits, agronomic practices, and weather but also on effective crop protection. European agriculture aims to reduce the use of harmful chemicals while maintaining yields.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Re-evaluating the list of high-production chemicals predicted to become Arctic contaminants [PDF]

open access: yes, 2010
The large number of historical and current organic chemicals in commerce, and the ability of these compounds to make their way from industrial to remote regions, has resulted in concerted efforts to predict which chemicals have the capacity to migrate ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

CONSERVATION TILLAGE AND PESTICIDE USE IN THE CORNBELT [PDF]

open access: yes
Adoption of conservation tillage can lead to substantial environmental benefits from reduced soil erosion. But benefits may be partially offset if adoption increases reliance on agricultural chemicals.

Feeding determinants in aphids with special reference to the Rose Aphid Macrosiphum rosae (L.) / by Zhongkui Peng. [PDF]

open access: yes, 1991
Bibliography: leaves 170-189.xi, 189 leaves : ill. (some col.) ; 30 cm.This thesis looks at aphid feeding determinants by type and location. It examines the role of leaf surface chemicals in the discrimination of host plants and the deterrent effect of ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...
