Economics of Pre-Plant, Topdress, and Variable Rate Nitrogen Application in Winter Wheat [PDF]

open access: yes
Past research about the efficiency of nitrogen application in winter wheat (Triticum aestivum L.) based on source and timing has produced inconsistent results. The majority of the literature used data from few locations over short time periods.

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

open access: yes, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

Near‐T2T genome assembly of Erigeron sumatrensis provides insights into polyploid evolution and the herbicidal efficiency of HPPD inhibitors

open access: yesNew Plant Protection, EarlyView.
The near‐T2T genome assembly of Erigeron sumatrensis reveals an allohexaploid origin, evolution, and the interaction between the herbicidal target of the HPPD family and mesotrione. Abstract Species of Erigeron, members of the family Asteraceae, have invaded and adapted to agricultural fields and uncultivated habitats worldwide. Erigeron sumatrensis is

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

Water Stress and Black Cutworm Feeding Modulate Plant Response in Maize Colonized by Metarhizium robertsii

open access: yesPathogens
Plants face many environmental challenges and have evolved different strategies to defend against stress. One strategy is the establishment of mutualistic associations with endophytic microorganisms which contribute to plant defense and promote plant ...

Sensitivity of Irish Pyrenopeziza brassicae populations to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides

open access: yesPest Management Science, EarlyView.
For three collections of Irish Pyrenopeziza brassicae populations fungicide sensitivity status to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides was determined using sensitivity screening in vitro. Molecular mechanisms of insensitivity have been identified for MBC and QoI in
