New fluorescent auxin probes visualise tissue‐specific and subcellular distributions of auxin in Arabidopsis

New Phytologist, Volume 230, Issue 2, Page 535-549, April 2021., 2021
Summary In a world that will rely increasingly on efficient plant growth for sufficient food, it is important to learn about natural mechanisms of phytohormone action. In this work, the introduction of a fluorophore to an auxin molecule represents a sensitive and non‐invasive method to directly visualise auxin localisation with high spatiotemporal ...

Direct somatic embryogenesis and plant regeneration from immature explants of chickpea

Biologia Plantarum, 2010
A protocol for plant regeneration via somatic embryogenesis was developed in two chickpea (Cicer arietinum L.) cultivars ICCV-10 and Annigeri. Somatic embryos were induced from immature cotyledons on Murashige and Skoog's (MS) medium supplemented with ...

Metabolism of Halophenols by 2,4,5-trichlorophenoxyacetic acid-degrading Pseudomonas cepacia [PDF]

Applied and Environmental Microbiology, 1983
Resting cells of 2,4,5-trichlorophenoxyacetic acid-grown Pseudomonas cepacia AC1100 were able to completely and rapidly dechlorinate several chlorine-substituted phenols, including 2,4,5-trichlorophenol, 2,3,4,6-tetrachlorophenol, and pentachlorophenol. Several other trichlorophenols were only partially dechlorinated.

Biodegradation of 2,4,5-trichlorophenoxyacetic acid by a pure culture of Pseudomonas cepacia [PDF]

Applied and Environmental Microbiology, 1982
A pure culture of Pseudomonas cepacia, designated AC1100, that can utilize 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as its sole source of carbon and energy was isolated. An actively growing culture of AC1100 was able to degrade more than 97% of 2,4,5-T, present at 1 mg/ml, within 6 days as determined by chloride release, gas chromatographic, and ...

Distribution and effects of 2,4,5-trichlorophenoxyacetic acid in cells of Bacillus megaterium [PDF]

Applied Microbiology, 1975
Cell death in a resting population of an asporogenous Bacillus megaterium was accelerated by ambient concentrations of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) equal to or greater than 10 mug/ml or 5 mug/mg of cells (dry weight), but only after prolonged exposure.

IN VITRO RHIZOGENESIS IN PAPAYA (CARICA PAPAYA L.) [PDF]

Journal of Plant Development, 2013
The seeds of two papaya (Carica papaya L.) cultivars ('Rainbow' and 'Sunrise Solo') were germinated on Murashige and Skoog (MS) medium with 3% sucrose, and free of plant growth regulators.

Biofilms, Bugs, and the Built Environment: Exploring Local and Landscape Drivers of Diatom and Macroinvertebrate Assemblages in Urban Stormwater Ponds

Water Environment Research, Volume 98, Issue 7, July 2026.
Urban stormwater ponds support pollution‐tolerant diatom and macroinvertebrate assemblages that are shaped more by local water quality, contaminants, and habitat features than by surrounding land use. Integrating biological monitoring can better inform stormwater management and urban biodiversity planning.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Identifying Gene Predictors of Chemicals Linked With Breast Cancer: A Machine Learning Analysis of MCF7 Cellular Transcriptomic Screening Data

Environmental and Molecular Mutagenesis, Volume 66, Issue 8, Page 425-441, October 2025.
ABSTRACT Breast cancer is the most prevalent cancer in women and has been linked to exposure to environmental chemicals. However, many chemicals have not been evaluated for relationships with this outcome. In this study, we analyzed RNA sequencing data from human breast cancer‐derived MCF7 cells exposed to hundreds of individual chemicals.
