Silicon chelates from plant waste promote in vitro shoot production and physiological changes in strawberry plantlets

For the first time, the effect of mechanocomposite (MC) based on biogenic silica and green-tea catechins on axillary shoot formation, physiological and biochemical characteristics of two strawberry cultivars (‘Alpha’ and ‘Solnechnaya polyanka’) was studied. The shoots were cultured on Gamborg-Eveleg’s medium (B-5) supplemented with 0.75 mg l(-1) 6-benzylaminopurine (BA) (control) and 0.0, 2.5, 5.0 or 10.0 mg l(-1) MC for 60 days. The highest regeneration responses (100%) and axillary shoot proliferation (up to 15.06 +/- 0.81) correlating with increasing fresh weight (FW), dry weight (DW) on the media supplemented with 5.0 mg l(-1) MC for both genotypes were recorded. The improvement in shoot regeneration accompanied with enhancing some antioxidant enzymes activity (superoxide dismutase and peroxidase) on the media supplemented with 5.0 mg l(-1) MC for both genotypes. The increase in endogenous H2O2 concentration displaying a high morphogenetic potential in the presence of 2.5 and 5.0 mg l(-1) MC was only observed in cv. ‘Alpha’ shoots. Overall, a positive effect of MC on the quality of in vitro shoots was established. Concentrations of photosynthetic pigments (chlorophylls a and b, and carotenoids), and their ratios (chlorophyll a/b, chlorophyll (a + b)/carotenoids) indicated a high physiological state of the plantlets grown with 5.0 mg l(-1) MC. The accumulation of endogenous cytokinin (iP) and indole-3-acetic acid (IAA) is associated with the effect of MC in various concentrations on the organogenic response of both cultivars. Thus, the outcomes of this study can be utilized for the development of new systems for a healthy planting material production using green chemistry approaches and recommended for commercial strawberry micropropagation.

Design of indole- and MCR-based macrocycles as p53-MDM2 antagonists

Macrocycles were designed to antagonize the protein-protein interaction p53-MDM2 based on the three-finger pharmacophore (FWL25)-W-19-L-23. The synthesis was accomplished by a rapid, one-pot synthesis of indole-based macrocycles based on Ugi macrocyclization. The reaction of 12 different alpha,omega-amino acids and different indole-3-carboxaldehyde derivatives afforded a unique library of macrocycles otherwise difficult to access. Screening of the library for p53-MDM2 inhibition by fluorescence polarization and H-1,N-15 HSQC NMR measurements confirm MDM2 binding.

Acute toxicity of the plant volatile indole depends on herbivore specialization

Herbivore-induced plant volatiles (HIPVs) provide direct benefits to plants as antimicrobials and herbivore repellents, but their potential as direct toxins to herbivores is unclear. Here, we assayed the larvicidal activity of six common HIPVs from three different biochemical pathways and tested the hypothesis that the larvicidal activity of HIPVs is related to the host specialization of the insect pest. We first assessed beta-caryophyllene, linalool, z-3-hexenyl acetate, z-3-hexenol, e-2-hexenal, and indole against the beet armyworm (Spodoptera exigua) and found that indole was sevenfold more toxic compared to the other volatiles when incorporated into the diet. Then, we tested the larvicidal activity of indole against six common, destructive pest caterpillars with varying host ranges. Consistent with our hypothesis, indole toxicity varied with caterpillar host range: indole toxicity was sevenfold higher in more specialized insect species relative to generalist insect species. That said, the LC50 of indole was comparable to other reported anti-herbivore agents even against the generalist caterpillars. Yet, indole in headspace had neither larvicidal nor ovicidal activity on any caterpillar species tested. These results support a key ecological precept of a trade-off between host specialization and chemical detoxification and also indicate that indole in particular is directly toxic to herbivores and therefore potentially useful in integrated pest management strategies.

I-2/TBHP/cyclohexanone a novel catalyst system for the oxidative dearomatization of indoles to indolin-3-ones at room temperature under solvent-free condition

Here we report a novel metal-free catalyst system for the oxidative dearomatization of indoles to indolin-3-ones. 12, TBHP and cyclohexanone together forms the catalyst system. Indole undergoes oxidative trimerization, whereas 2-substituted indole gives oxidative dimerized product. No solvent is required for the reaction and is carried out at room temperature. Electron-deficient indoles give lower or no yields, while electron-rich indoles produce excellent yields. The mechanism of the reaction is studied.

” Back-to-Front ” Indole Synthesis Using Silver(I) Catalysis: Unexpected C-3 Pyrrole Activation Mode Supported by DFT

An efficient silver(I)-catalyzed method is reported for the synthesis of substituted indoles, most notably 5-hydroxy-derivatives, via pi-acidic alkyne activation. Most methods for the preparation of indoles involve annulation of a benzene precursor, but the method reported herein is unusual in that pyrrole precursors are used. Density Functional Theory (DFT) studies suggest that these reactions proceed via initial activation of the pyrrole C-3 position before undergoing subsequent rearrangement, contradicting the conventional wisdom that pyrroles are more nucleophilic through C-2.

Meta-topolin and liquid medium enhanced in vitro regeneration in Scaevola taccada (Gaertn.) Roxb

Scaevola taccada (Gaertn.) Roxb. is a hemi-sclerophyllous littoral shrub of the family Goodeniaceae. It is a salt-tolerant plant and used in soil reclamation and coastal landscaping programs to control beach erosion. The present article reports a reproducible in vitro regeneration system using meta-topolin (mT) through liquid medium employing nodal segment cultures. The highest number of axillary shoots (5.8 +/- 0.29) was differentiated on Murashige and Skoog’s (MS) medium containing meta-topolin (1.5 mg L-1). The amplification of shoots (49.8 +/- 0.37) and fresh growth was achieved by recurrent subcultures on liquid MS medium supplemented with 0.25 mg L(-1)mT and 0.15 mg L-1 indole-3-acetic acid (IAA) in the presence of additives (50 mg L-1 ascorbic acid + 25 mg L-1 citric acid, adenine sulphate and l-arginine). Rooting and acclimatization was simultaneously achieved using concurrent ex vitro rooting and acclimatization (CEVRA) technique by pulse treating the shoot base with 300 mg L-1 IBA for 5 min. The in vitro developed shoots represented a maximum percentage (100%) of rooting in autoclaved soilrite in a greenhouse. After 2 mo, the plantlets were established in the field with cent percentage survival success. The genetic fidelity analysis using inter simple sequence repeats (ISSR) DNA molecular markers developed maximum of 55 monomorphic bands and revealed the genetic homogeneity of in vitro regenerated plantlets with the mother plant.

Accumulation of volatile constituents in agar and bioreactor shoot cultures of Verbena officinalis L.

Key message Microshoot cultures of Verbena officinalis, grown in temporary immersion bioreactors, were investigated in terms of essential oil content and composition of volatile fraction In vitro shoot cultures of common vervain (Verbena officinalis L., Verbenaceae) were established and evaluated for essential oil content. The shoots were maintained as stationary microshoot culture, grown on Schenk-Hildebrandt medium supplemented with 9.84 mu M of 2-isopentenyladenine and 1.0 mu M of thidiazuron. The shoots were further adapted to grow in two temporary immersion bioreactors (RITA and Plantform), using Schenk-Hildebrandt medium supplemented with 4.92 mu M indole-3-butyric acid. The best growth, in terms of dry weight production, was recorded for agar culture (0.73 g l(-1) day(-1)), followed by 35 days (day) Plantform (0.53 g l(-1) day(-1)), 35 days RITA (0.42 g l(-1) day(-1)) and 56 days Plantform culture (0.29 g l(-1) day(-1)). The volatile fractions were obtained by simultaneous hydrodistillation-extraction of the plant materials using Likens-Nickerson apparatus. Aerial parts of V. officinalis intact plant and 56 d Plantform culture had the highest essential oil content (8.1 g kg(-1)) whereas the stationary agar culture excelled in essential oil productivity (5.0 mg l(-1) day(-1)). The volatile oils isolated from in vitro shoots contained 1-octen-3-ol, benzyl alcohol, phenethyl alcohol, coumaran and hexadecenoic acid as major constituents. 1-Octen-3-ol was the predominant (> 50%) constituent of 35 day shoot cultures maintained in temporary immersion bioreactors whereas coumaran (19%) and hexadecanoid acid (21%) prevailed in stationary microshoot culture. The volatile fraction obtained from aerial parts of V. officinalis intact plant was composed mainly of hexadecanoic acid (> 20%), linalool (> 8%), anethole (> 5%) and carvone (> 3%).
