The potential of three auxin analogs, 4-, 5-, and 6-azidoindole-3-acetic (4-N(3)IAA, 5-N(3)IAA, and 6-N(3)IAA), as photoaffinity labeling agents for the detection and isolation of auxin receptors was assessed by irradiating these compounds at 365 nm on TLC plates, in solution, and in contact with soybean (Glycine max L. Merr. var. Wayne) hypocotyl. Photolysis on TLC plates produces immobile spo...

Thirteen auxenic compounds were discovered in a screen of 10 000 compounds for auxin-like activity in Arabidopsis roots. One of the most potent substances was 2-(4-chloro-2-methylphenoxy)-N-(4-H-1,2,4-triazol-3-yl)acetamide (WH7) which shares similar structure to the known auxenic herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). A selected set of 20 analogues of WH7 was used to provide detaile...

Auxin (indole-3-acetic acid) enhances movement of tritiated water into and out of stem segments of etiolated peas. The time required for water in the tissue to attain one-half equilibrium with water in the surrounding solution is significantly shorter and the initial flux rate is higher in auxin-treated sections. The response is one of the most rapid to auxin, occurring well within 1 min after ...

Canaline and canavanine (inhibitors of polyamine biosynthesis) effects on root and shoot formation were determined in vitro for etiolated hypocotyl segments of leafy spurge (Euphorbia esula L.). Canaline (an ornithine analogue) at 10 to 100 μmol/L inhibited root and shoot formation. The simultaneous application of putrescine did not reverse canaline-induced inhibition of root formation. Ornithi...

Plants have been used for medicinal application ever since man has begun caring for his body and health. For centuries, the world has depended on the valuable properties of plant as a source of healing. Based on the considerable knowledge about these plant species from the ancient books, the modern systems of medicine have enabled these plants to find a place in the commercial MIcroProPAGAtIon ...

In vitro rooting as one of the most critical steps micropropagation is affected by various extrinsic (e.g., medium composition, auxins) and intrinsic factors species, explant). Passiflora in adventitious a difficult, complex, non-linear process. Since multivariable complex biological process, efficient reliable computational approaches such machine learning (ML) are required to model, predict, ...
