Methylglyoxal destroys Agrobacterium tumefaciens crown gall tumours in Nicotiana tabacum without any adverse effect on the host plant

, 2011
Methylglyoxal (MG) is a highly reactive α-oxoaldehyde, demonstrating anticancer effect on plant neoplastic tumours. In in vivo studies it was observed that MG destroyed crown gall tumours in Nicotiana tabacum produced by Agrobacterium tumefaciens ...

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, Volume 251, Issue 3, Page 1143-1160, August 2026.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Blocking of Attachment to Cell Wall as a Resistance Response to Crown Gall Bacteria Agrobacterium tumefaciens by Roses

Journal of the Japanese Society for Horticultural Science, 2005
バラ根頭がんしゅ病抵抗性の発現機構を明らかにするために, Agrobacterium tumefaciensの植物細胞壁への付着に着目し, バラの抵抗性の高低と菌の付着との関係について走査型電子顕微鏡を用いて比較検討した. 無接種区において抵抗性が高い‘PEKcougel’および‘Lifirane’では顆粒物質が多量に分泌され, 植物細胞壁表面が覆われていたのに対して, 抵抗性が低い‘Dukat’, Rosa multiflora‘Matsushima No. 3’およびRosa canina‘Pfander’では顆粒物質の分泌が少なく, 細胞壁表面が露出していた.

Soil Pathobiome in Agroecosystems and Forests

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
This review synthesises current knowledge on the soil pathobiome across agroecosystems, horticulture, and forests, highlighting how climate change and intensive management disrupt microbial communities and promote pathogen accumulation. It emphasises soil health as a key component of the One Health framework, linking ecosystem, plant, animal, and human

Intestinal Organoid‐Based Mathematical Modeling Predicts Clinical Gastrointestinal Toxicity of Oral Oncology Drugs

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 5, May 2026.
ABSTRACT Gastrointestinal (GI) toxicity is a common and potentially severe side effect of antiproliferative cancer therapies that often requires dose reduction or treatment interruption. Despite the clinical implications, there are currently no robust strategies for quantitative preclinical assessment of GI toxicity.

The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, Volume 101, Issue 2, Page 1003-1035, April 2026.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Elevation reverses the effects of forest structure on folivory and leaf asymmetry

Functional Ecology, Volume 40, Issue 4, Page 1061-1073, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Centuries of timber production have homogenized many forests by reducing variation in canopy density and deadwood availability, with far‐reaching consequences for biodiversity and trophic interactions.

International Biological Flora: Loranthus europaeus*

Journal of Ecology, Volume 114, Issue 4, April 2026.
Loranthus europaeus is a deciduous hemiparasitic species native to Europe and western Asia, primarily parasitizing oaks. It forms xylem connections via haustoria, extracting water and nutrients while exhibiting high transpiration and low water‐use efficiency.
