Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Impact of Indian Mustard (Brassica juncea) and Flax (Linum usitatissimum) Seed Meal Applications on Soil Carbon, Nitrogen, and Microbial Dynamics

open access: yesApplied and Environmental Soil Science, 2012
There is a critical need to investigate how land application of dedicated biofuel oilseed meals affects soil ecosystems. In this study, mustard (Brassica juncea) and flax (Linum usitatissimum) seed meals and sorghum-sudangrass (Sorghum bicolor) were ...

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Production potential, nutrient uptake and economics of Indian mustard (Brassica juncea) under integrated nutrient management practices

open access: yesThe Indian Journal of Agricultural Sciences, 2014
A field experiment was conducted during the winter (rabi) seasons of 2009-10 and 2010-11 to study the production potential, nutrient uptake and economics of Indian mustard (Brassica juncea L.) under eight treatments of organic sources and three levels of

GLAND CELLS IN HYDRA [PDF]

open access: yes, 1986
The proliferative capacity of gland cells in Hydra attenuata was investigated. The results indicate that both gland cell proliferation and interstitial cell differentiation to gland cells contribute to the maintenance of the whole population.

Sustainable flower bulb production: prototyping integrated flower bulb production systems on sandy soils in The Netherlands [PDF]

open access: yes, 2002
Flower bulb production in The Netherlands is economically successful. However, production methods rely heavily on external inputs, causing contamination of surface and ground water. The use of pesticides has been estimated 100 kg active ingredient (a.i.)

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.
