The continuing significance of chiral agrochemicals

open access: yesPest 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.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Starchy Pollen in Commelinoid Monocots [PDF]

open access: yesAnnals of Botany, 2001
Abstract The Commelinoid monocots are a monophyletic group comprising the Arecales, Commelinales, Poales and Zingiberales, plus the unplaced family Dasypogonaceae. Pollen from 149 taxa was examined qualitatively for starch as the primary storage product. Starchy pollen was found in 134 taxa (90% of the sample) of Commelinoid monocots.

Problems and possibilities of monocot transformation

open access: yesBiologia Plantarum, 2011
Biotechnological improvement of monocots is often hampered by the lack of efficient regeneration systems, requisite wound responses and low cell competence. Despite these limitations, the biolistic and Agrobacterium methods have been successfully used to

A Breakthrough in Monocot Transformation Methods [PDF]

open access: yesThe Plant Cell, 2016
The ability to generate transgenic plants without regard to cultivar or genotype can be considered a holy grail of cereal crop transformation. Despite years of effort, it has been remarkably difficult to develop efficient methods for transformation of cereals.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.
