The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Repeated use of green-manure catch crops in organic cereal production - grain yields and nitrogen supply [PDF]

, 2011
By restricted access to manure, nitrogen (N) supply in organic agriculture relies on biological N-fixation. This study compares grain yields after one full-season green manure (FSGM) to yields with repeated use of a green-manure catch crop.

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Biomass production and N2-fixation in seven grass-legume mixtures [PDF]

, 2010
Inclusion of forage legumes in low-input grassland mixtures improves biomass production and soil fertility trough addition of nitrogen (N) from N2-fixation.

Environmental impacts of grazed pastures [PDF]

, 2010
Large nitrogen (N) surplus and return of excreta-N in localised patches at high N rates in intensively grazed pasture systems markedly increases the risk of N losses to waterways and the atmosphere. Here are described the main routes of N input to grazed

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

Australian Veterinary Journal, EarlyView.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...

Orthology guided transcriptome assembly of Italian ryegrass and meadow fescue for single-nucleotide polymorphism discovery [PDF]

, 2016
Single-nucleotide polymorphisms (SNPs) represent natural DNA sequence variation. They can be used for various applications including the construction of high-density genetic maps, analysis of genetic variability, genome-wide association studies, and ...

Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

The FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

Novel genetic engineering technology which increases leaf lipid content modifies the ensiling properties of perennial ryegrass : a thesis presented in partial fulfillment of the requirements for the degree of Masters in Agricultural Science at Massey University, Palmerston North [PDF]

, 2016
A novel strategy to increase the metabolisable energy (ME) yield of pastures has been the development of a genetic engineering technology which increases the leaf lipid content and biomass production of perennial ryegrass (PRG).

Effect of four plant species on soil 15N-access and herbage yield in temporary agricultural grasslands [PDF]

, 2013
Positive plant diversity-productivity relationships have been reported for experimental semi-natural grasslands (Cardinale et al. 2006; Hector et al. 1999; Tilman et al. 1996) as well as temporary agricultural grasslands (Frankow-Lindberg et al.
