Evidence for Two Indoleacetic Acid-Induced Growth Responses in the Avena Straight-Growth Indoleacetic Acid Assay [PDF]

Plant Physiology, 1993
Floating Avena sativa L. cv Victory coleoptile segments were used to determine whether the straight-growth indoleacetic acid (IAA) assay can be reconciled with the Avena curvature assay and the Cholodny-Went theory of photo- and gravitropism. Measurements of segment length after 5 h yield sigmoid-shaped IAA dose-response curves with the growth rate ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 843-860, May 2026.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Endophytic Biostimulant Pyrroloquinoline Quinone Enhances Banana Growth and Primes Immunity Against Fusarium Wilt

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Pyrroloquinoline quinone (PQQ) is a redox cofactor derived from prokaryotes that participates in various biological processes involving dehydrogenase enzymes. Previous field trials identified a PQQ‐producing endophyte, Burkholderia seminalis 869T2, which enhances banana growth and reduces Fusarium wilt incidence from 24.5% to 3.4%.

Indoleacetic Acid and the Synthesis of Glucanases and Pectic Enzymes [PDF]

Plant Physiology, 1968
Indoleacetic acid (IAA) and/or inhibitors of DNA, RNA or protein synthesis were added to the apex of decapitated seedlings of Pisum sativum L. var. Alaska. At various times up to 4 days, enzymic protein was extracted from a segment of epicotyl immediately below the apex and assayed for its ability to hydrolyse polysaccharides or their derivatives. With

Bacillus coagulans regulates gut microbiota and ameliorates the alcoholic-associated liver disease in mice

Frontiers in Microbiology
IntroductionAlcoholic-associated liver diseases (ALD) are now widespread issues worldwide. Alcoholic-induced chronic dysbiosis of the gut microbiota is one of the factors in the pathophysiology of ALD.MethodsIn this work, we employed a chronic-binge ...

Transcriptomic and phosphoproteomic profiling and metabolite analyses reveal the mechanism of NaHCO3-induced organic acid secretion in grapevine roots

BMC Plant Biology, 2019
Background Organic acid secretion is a widespread physiological response of plants to alkalinity. However, the characteristics and underlying mechanism of the alkali-induced secretion of organic acids are poorly understood.

Saffron Alters Microbial Amino Acid Metabolism and Neurotransmitter Production in a Defined Gut Consortium

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Graphical representation of the metabolic pathways modulated by saffron within defined microbial communities. In the tryptophan pathway, saffron decreased levels of tryptophan and anthranilic acid while increasing concentrations of indole‐3‐acetic acid and tryptamine.

Microbial Life Inside Posidonia Seeds: Beneficial Endophytes and Implications for Marine Plant Health

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Seagrass Posidonia oceanica seeds host diverse bacterial and fungal endophytes with plant‐growth–promoting traits, including nitrogen fixation and hormone production. These microbes may be vertically transmitted and support seedling establishment, offering insights for marine plant conservation and biotechnological applications.

Enhancing Diagnostic Pathways for Bronchopulmonary Neuroendocrine Tumors: Assessment of the South Wales Neuroendocrine Tumor Service Transformation

Thoracic Cancer, Volume 17, Issue 8, April 2026.
Implementation of a dedicated neuroendocrine cancer service in South Wales significantly shortened diagnostic and treatment timelines for bronchopulmonary NETs, demonstrating the benefits of coordinated specialist input. ABSTRACT Background Bronchopulmonary neuroendocrine tumors (bpNETs) are uncommon lung neoplasms posing significant diagnostic and ...

Indoleacetic Acid Oxidase: A Dual Catalytic Enzyme? [PDF]

Plant Physiology, 1972
The isolation of a unique enzyme capable of oxidizing indoleacetic acid, but devoid of peroxidase activity, has been reported for preparations from tobacco roots and commercial horseradish peroxidase. Experiments were made to verify these results using enzyme obtained from Betula leaves and commercial horseradish peroxidase.
