Formation of indoleacetic acid by intestinal anaerobes [PDF]

Journal of Bacteriology, 1975
Indoleacetic acid was produced from tryptophan by only three of 23 intestinal anaerobes studied. Evidence is presented to show that the formation of indoleacetic acid proceeds through the intermediate, indolepyruvic acid, via transamination with alpha-ketoglutarate rather than by tryptamine pathway.

Ingenious characterization and assessment of lentil germplasm collection to aphid Acyrthosiphon pisum stress unveils distinct responses

Frontiers in Plant Science, 2022
Lentil cultivation is often hampered by aphid population outspreads with detrimental impacts to crop development and production, challenging food safety and agriculture sustainability. The pea aphid (Acyrthosiphon pisum) is a significant threat to lentil

Comparison of Zeatin Indoleacetate with Zeatin and Indoleacetic Acid in the Tobacco Bioassay [PDF]

Plant Physiology, 1972
Zeatin indole-3-acetate, 6-[4-(indole-3-acetoxy)-3-methyl-trans-2-butenylamino]purine, is at least as effective as zeatin on a molar basis in satisfying the cytokinin requirement for growth and bud formation in tobacco bioassays. It is less effective than indole-3-acetic acid and is needed as a variable function of the cytokinin concentration for ...

Shoot organogenesis in leaf explants of Hydrangea macrophylla ‘Hyd1’ and assessing genetic stability of regenerants using ISSR markers [PDF]

, 2011
For the first time, an in vitro regeneration protocol of Hydrangea macrophylla 'Hyd1' was developed. Effects of different plant growth regulators (PGRs) on shoot regeneration were investigated jointly with selecting optimal basal media and cefotaxime ...

IL4I1⁺ Macrophages and TDO2⁺ Myofibroblasts Drive AhR‐Mediated Immunosuppression and Ferroptosis Resistance in Solid Predominant Lung Adenocarcinoma

Advanced Science, EarlyView.
Solid predominant lung adenocarcinoma exhibits an immune‐excluded, ferroptosis‐resistant niche enriched with IL4I1⁺ TAMs and TDO2⁺ myCAFs. Spatial and multi‐omics analyses reveal AhR‐driven crosstalk that promotes T cell exhaustion and therapy resistance. Blocking AhR with CH‐223191 restores ferroptosis sensitivity, and its combination with ferroptosis

Effects of severe drought stress on the physiology and biochemistry characteristics of Welsh onion (Allium fistulosum L. var. giganteum Makino) seedlings

Horticultural Science, 2023
The physiological regulation of Welsh onion seedlings was explored under short- and long-term drought stress. The Welsh onion cultivar 'Neicong 3' was grown in pots under drought stress (22.5-25% soil water content) or controlled watering conditions (65 ...

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 ...

The effect of 3-indoleacetic acid on the response of Lactobacillus arabinosus 17-5 to nicotinamide [PDF]

, 1949
Lactobacillus arabinosus 17-5 has been widely used as an assay organism for nicotinic acid (NA) since the development of the method by Snell and Wright (1). Although it has been realized that other substances present in tissue extracts may interfere with
