Tissue culture has been widely used for the propagation of papaya (Carica papaya L.). Generally, agar-based media supplemented with the appropriate amount of indole-3-butyric acid (IBA) is used for the in-vitro rooting and root elongation of the papaya explants. However, it is usually resulted in a difficulty in adventitious root (AR) formation and turns into callus formation. The AR formation was influenced by miscellaneous factors, however little is known of the related regulative mechanisms. In this study, RNA-seq was performed on samples collected from leaf-inoculation (LI) and stem-inoculation (SI) GZY6 shoot explants to reveal their different rooting phenotypes. Here, we found that the ARs were induced from in GZY6 (79.17%), GZG4 (63.33%), and GZM26 (37.23%) hermaphroditic papaya shoot explants obtained by LI method after 2 weeks of culture in root-induction medium, but calli were formed rather than AR from the explants obtained by SI method in root-induction medium. The SI and LI shoot explant samples of GZY6 genotypes (the rooting percentage was highest in the three genotypes) were used for the transcriptomic analyses. A total of 2498 differentially expressed genes (DEGs) were identified in the LI vs. SI samples and annotated into 73 Gene ontology (GO) terms. The GO analysis revealed that oxidative-stress, defense-response, and stimulus-response GO terms were significantly different between the LI and SI shoot explants and that the genes are involved in anaerobic respiration and reactive oxygen species (ROS) metabolism pathways. Twelve selected anaerobic and ROS metabolic pathways-related DEGs were used to validate the RNA-seq data by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The activity of superoxide dismutase (SOD) and peroxidase (POD) and the concentration of hydrogen peroxide (H2O2) increased in the SI explants. ARs formation and development were significantly higher in the SI explants in perlite medium than in agar medium, when both were not supplemented with IBA. Papaya shoot explants absolutely formed ARs in peat medium after stem bases dipping in 1 mg mL(-1) IBA for 3 s. Our results indicate that the root-induction medium supplemented with agar and IBA would be mostly limited AR emergence and induced callus formation in SI explants, respectively. This study provides basic data for establishing a healthy and functional rooting system for in vitro papaya propagation.

Pea GH3 acyl acid amidosynthetase conjugates IAA to proteins in immature seeds of Pisum sativum L. – A new perspective on formation of high-molecular weight conjugates of auxin

Gretchen Hagen 3 (GH3) acyl acid amidosynthetases are encoded by early auxin-responsive genes and catalyze an ATP-dependent biosynthesis of IAA-amino acid conjugates. An amide conjugate of IAA, indole-3-acetylaspartate (IAA-aspartate, IAA-Asp), is a predominant form of bound auxin in immature seeds of pea. However, there is some evidence that IAA is also able to form high molecular weight amide conjugates with proteins in pea and other plant species. In this short study we report that recombinant PsGH3 IAA-amino acid synthetase, which exhibits a preference for the formation of IAA-Asp, can also conjugate IAA with the protein fraction from immature seeds of pea (S-10 fraction). We studied [C-14]IAA incorporation to the S-10 protein fraction by two assays: TLC method and protein precipitation by trichloroacetic acid (TCA). In both cases, radioactivity of [C-14] IAA in the protein fraction increases in comparison to the control (without PsGH3), about 9.3- and 3.17-fold, respectively. L-Asp, as a preferred substrate in the IAA conjugation catalyzed by PsGH3, down-regulates [C-14] IAA conjugation to the proteins as shown by the TLC assay (similar to 2.8-fold decrease) and the TCA precipitation variant (similar to 2-fold decrease). Moreover, L-Trp that competes with Asp for the catalytic site of PsGH3 and inhibits activity of the enzyme, diminished radioactivity of [C-14]IAA-proteins about 1.2- and 2.8-fold, respectively. Taking into account that amino group of an amino acid or a protein acts as an acceptor of the indole-3-acetyl moiety from IAA-AMP intermediate during GH3-dependent conjugation, we masked amine groups (alpha- and epsilon-NH2) of the S-10 protein fraction from pea seeds by reductive alkylation. The alkylated proteins revealed about 3- and 2.8-fold lower radioactivity of [C-14]IAA than non-alkylated fraction for TLC and TCA precipitation variant, respectively. This is a first study demonstrating that formation of high molecular weight IAA conjugates with proteins is catalyzed by a GH3 acyl acid amidosynthetase.

Iodine(III) Reagent-Mediated Intramolecular Amination of 2-Alkenylanilines to Prepare Indoles

A variety of 3-substituted and 2,3-disubstituted indoles were synthesized efficiently in good yields through the intramolecular amination of 2-alkenylanilines promoted by readily available iodine(III) reagents in a short reaction time. Mechanistic studies showed that the reaction pathway went through a nitrenium ion and that 3-acetoxy indoline was the key intermediate in the indole formation. The indole product was easily prepared on a gram scale and amination also proceeded smoothly using catalytic 3,5-dimethylphenyl iodine in the presence of mCPBA. Furthermore, the indolo[3,2-a]carbazole scaffold was prepared in good yield in six steps from commercial ortho-iodoaniline.

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 173903-47-4. Safety of Tizoxanide.

Role of the base Cs2CO3 on the palladium-catalyzed intramolecular cyclization of two bromoindole derivatives to yield paullone-type products

Reactions for the palladium-catalyzed intramolecular cyclization of the o-bromoindole and the o-bromo-N-methyl-indole derivatives in the presence and absence of base (Cs2CO3) were explored through DFT calculations. For the base-free reactions, the palladium atom firstly interacts with the aromatic rings of the indole molecule to yield a stable adduct. Once this adduct has been formed, reaction proceeds readily to the oxidative addition intermediate that arises from the insertion of the metal atom into the C-Br bond of the organic fragment. Further steps leading to the paullone (or dimethyl paullone) product, mainly those involving the metalation and deprotonation of the inserted intermediate, are not energetically viable for these reactions. When the effect of the base on the metalation-deprotonation steps is modeled by replacing the bromide ion with CO32- in the metal-inserted structure, a feasible pathway connecting the oxidative addition intermediate with the paullone-type product was located for each of the investigated reactions. The results emerging from this study suggest that palladium can insert into the C-Br bond of the indole derivatives to yield the oxidative addition intermediate (without participation of the base). However, the metalation and deprotonation steps that evolve to the paullone-type product take place via a concerted action involving both the metal and the base.Graphical abstract Metalation and deprotonation steps that evolve to the paullone-type product take place via a concerted action involving both the metal and the base.
