Electrochemical Determination of Indole-3-carboxylic Acid Using Carboxyl Functionalized Multi-Walled Carbon Nanotubes Modified Glassy Carbon Electrode

Indole-3-carboxylic acid (ICA) was detected by differential pulse voltammetry using a glassy carbon electrode (GCE) modified carboxylic multi-walled carbon nanotubes (MWCNTs-COOH). Electrochemical impedance spectroscopy (EIS) and different pulse voltammetry (DPV) were used to study electrochemical properties of the modified electrode. The modified electrode shows higher electrocatalytic activity toward the oxidation of Indole-3-carboxylic acid than those of the carbon electrode modified multi-walled carbon nanotubes or bare glassy carbon electrode. After the experimental conditions were optimized, the linear calibration curve was obtained in the range from 0.75 to 100 mu mol.L-1 with a low detection limit of 0.25 mu mol.L-1 (S/N = 3). The modified electrode was successfully used for the determination of the analytes in real samples, which obtained satisfactory results.

Hormonal responses associated with acclimation to freezing stress in Lolium perenne

Complex phytohormonal analyses revealed hormone changes underlying the freezing response of perennial ryegrass (Lolium perenne L.). Comparisons among sensitive (code of accession 1/61), highly tolerant (5/101) and semi-tolerant (6/104; sensitive without acclimation, but tolerant after acclimation) genotypes allowed identification of changes associated with freezing tolerance. The main response to freezing stress (-7 degrees C for four days) was a significant elevation of abscisic acid (ABA) in all tissues of all genotypes, supported by elevation of jasmonic acid (JA) in leaves, and of salicylic acid (SA) in crowns and roots. Jasmonate-isoleucine increase was observed in roots of the tolerant genotype. The auxin (indole-3-acetic acid) levels showed relatively minor changes, while cytokinins exhibited up-regulation in crowns of sensitive genotypes. Tolerant genotypes exhibited decreased levels of highly active cytokinin trans-zeatin compensated by elevated low-active cis-zeatin, involved in stress responses. Cold acclimation (3 degrees C for seven days) applied prior frost treatment was associated with stimulation of plant defences, especially expression of ice recrystallisation inhibition protein LpIRI3. Acclimation diminished the impact of subsequent freezing treatment as indicated by lower up-regulation of stress hormones ABA, JA and SA in all tested tissues (with the exception of SA in crowns and roots of sensitive genotype) and upregulation of active cytokinins in tolerant and semi-tolerant genotypes, especially in crowns and roots.

In Vitro and Cryobiotechnology Approaches to Safeguard Lupinus rivularis Douglas ex Lindl., an Endangered Plant in Canada

Conservation of threatened flora in genetic collections ex situ using in vitro culture and cryopreservation is receiving an increasing recognition as a complementary strategy to in situ conservation in natural habitats. The present study is focused on an integrated approach which involves conservation and propagation, emphasizing the usefulness of cryopreservation techniques for germplasm conservation of streambank lupine (Lupinus rivularis Douglas ex Lindl.), an endangered species in Canada. This included in vitro seed germination on Murashige and Skoog basal medium supplemented with 1 mu M thidiazuron to induce multiple shoot formation, micropropagation on a medium with 5 mu M benzylaminopurine, and in vitro rooting on medium with 20.0 mu M indole-3-butyric acid. Cryopreservation of seeds and shoot tips of in vitro grown plants was successful with over 60% seed germination and 62% regrowth of cryopreserved shoot tips, respectively. Plants developed from cryopreserved seeds had chlorophyll contents in leaves and the growth characteristics including the development of inflorescence, similar to plants raised from non-cryopreserved seeds. These results provide further evidence that the combination of micropropagation with cryopreservation of seeds and vegetative parts may effectively facilitate long-term preservation of L. rivularis and other endangered species.

Dehydroxylated C-3 Alkylation of Indole Accompanied by 1,2-Sulfur Migration

A metal-free sulfur neighboring group participation C-3 alkylation method between beta-sulfur-alpha-alcohol and indole is documented. Due to its considerable generality and excellent selectivity, this method has been provided a facile access to synthetically useful alpha-indole-beta-functions. Meanwhile, unlike traditional Friedel-Crafts and Mitsunobu reactions, the unique chemoselectivity and regioselectivity may be attributed to a synergetic mechanism with simultaneous C-O cleavage, C-S migration, and C-C formation occurring in the developed reaction.

Multiple Plant Growth-Promotion Traits in Endophytic Bacteria Retrieved in the Vegetative Stage From Passionflower

Bacteria exhibiting beneficial traits like increasing the bioavailability of essential nutrients and modulating hormone levels in plants are known as plant growth promoting (PGP) bacteria. The occurrence of this specific group of bacteria in the endophytic environment may reflect the decisive role they play in a particular condition. This study aimed to determine the taxonomical diversity of the culturable bacterial endophytes, isolated in the vegetative stage of passionflower (Passiflora incarnata), and assess its potential to promote plant growth by phenotypic and genotypic approaches. The sequencing and phylogenetic analysis of the 16S rRNA gene allowed us to classify 58 bacterial endophytes into nine genera. Bacillus (70.7%) was the most dominant genus, followed by Pseudomonas (8.6%) and Pantoea (6.9%). A few isolates belonged to Rhodococcus and Paenibacillus, whereas the genera Lysinibacillus, Microvirga, Xanthomonas, and Leclercia were represented by only one isolate. The strains were tested for nitrogen fixation, phosphate solubilization, indole-acetic-acid synthesis, and siderophore production. Moreover, PGP related genes (nifH, ipdC, asb, and AcPho) were detected by PCR-based screening. Most of the isolates (94.8%) displayed a potential for at least one of the PGP traits tested by biochemical assays or PCR-based screening. Nine strains were selected based on results from both approaches and were evaluated for boosting the Cape gooseberry (Physalis peruviana) germination and growth. All tested isolates improved germination in vitro, and the majority (78%) increased growth parameters in vivo. The results suggested that most of culturable bacteria inhabiting P. incarnata in the vegetative stage could be used as probiotics for agricultural systems. Besides, their occurrence may be associated with specific physiological needs typical of this development stage.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 27955-94-8. Quality Control of 4,4′,4”-(Ethane-1,1,1-triyl)triphenol.
