LF1 regulates the lateral organs polarity development in rice

The patterning of adaxial-abaxial tissues plays a vital role in the morphology of lateral organs, which is maintained by antagonism between the genes that specify adaxial and abaxial tissue identity. The homeo-domain leucine zipper class III (HD-ZIP III) family genes regulate adaxial identity; however, little information is known about the physical interactions or transcriptionally regulated downstream genes of HD-ZIP III. In this study, we identified a dominant rice mutant, lateral floret 1 (lf1), which has defects in lateral organ polarity. LF1 encodes the HD-ZIP III transcription factor, which expressed in the adaxial area of lateral organs. LF1 can activate directly the expression of LITTLE ZIPPER family gene OsZPR4 and HD-ZIP II family gene OsHOX1, and OsZPR4 and OsHOX1 respectively interact with LF1 to form a heterodimer to repress the transcriptional activity of LF1. LF1 influences indole-3-acetic acid (IAA) content by directly regulating the expression of OsYUCCA6. Therefore, LF1 forms negative feedback loops between OsZPR4 and OsHOX1 to affect IAA content, leading to the regulation of lateral organs polarity development. These results reveal the cross-talk among HD-ZIP III, LITTLE ZIPPER, and HD-ZIP II proteins and provide new insights into the molecular mechanisms underlying the polarity development of lateral organs.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 69-33-0 is helpful to your research. Safety of 4-Amino-7-(¦Â-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine.

A chemo- and regioselective C6-functionalization of 2,3-disubstituted indoles: highly efficient synthesis of diarylindol-6-ylmethanes

An organocatalytic chemo-and regioselective C6-functionalization of 2,3-disubstituted indoles has been established via a reaction with ortho-hydroxybenzyl alcohols, which afforded biologically important diarylindol- 6-ylmethanes in overall high yields (up to 99% yield). This protocol not only provides an efficient method for constructing biologically important diarylindol-6-ylmethane frameworks in an atom economical fashion, but also serves as a good example for the direct catalytic C6-functionalization of indoles, which have been rarely investigated. More importantly, the preliminary biological evaluation revealed that this new class of diarylindol-6-ylmethanes exhibited strong cytotoxicity to HeLa cell lines.

Pantoea agglomerans YS19 poly(A) polymerase I gene possesses the indole-sensing sequence in the promoter region

Pantoea agglomerans YS19 is a predominant diazotrophic endophyte with multiple growth-promoting effects on its host plant that was isolated from rice. Indole is confirmed to induce many changes of physiological and biochemical characteristics in bacteria. Although YS19 cannot produce indole, it can sense indole in the environment and be regulated by indole. Here, using gfp as a reporter gene, we constructed a series of recombinant plasmids containing the promoter region of the poly(A) polymerase I gene (pcnB) fusedwith gfp, and compared the green fluorescence intensity at different concentrations of exogenous indole by a flow cytometer. In this research, we confirmed that exogenous indole significantly inhibited the expression of pcnB by its promoter; the regulation sequence sensitive to indole in the promoter region of the pcnB gene (In-pcnB) was between -129 and -88 bp. In-pcnB is widely distributed and strictly conserved in the same genus. These results suggest novel roles of In-pcnB in P. agglomerans YS19, showing its special relation to the indole regulatory pathway.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 28721-07-5 help many people in the next few years. Formula: C15H12N2O2.

Effects of indole and indoxyl on the intracellular oxidation level and phagocytic activity of differentiated HL-60 human macrophage cells

Indoxyl, a derivative of indole originating from tryptophan, may undergo phase-II sulfate-conjugation pathway, thereby forming indoxyl sulfate (IS) in vivo. We previously reported that IS, a well-known uremic toxin, can increase the intracellular oxidation level and decrease the phagocytic activity in a differentiated HL-60 human macrophage cell model. Using the same cell model, the current study aimed to investigate whether indole and indoxyl (the metabolic precursors of indoxyl and IS, respectively) may cause macrophage immune dysfunction. Results obtained indicated that intracellular oxidation level and cytotoxicity markedly increased upon treatment with indole and indoxyl, in comparison with IS. Incubation of the cells with indole and indoxyl also resulted in attenuated phagocytic activity. Human serum albumin (HSA)-binding assay confirmed that tryptophan and IS, but not indole and indoxyl, could selectively bind to the site II in HSA. Collectively, the results indicated that indole and indoxyl may strongly down-regulate the phagocytic immune function of macrophages, whereas IS, formed upon sulfate conjugation of indoxyl, may exhibit enhanced HSA-binding capability, thereby reducing the adverse effects of indoxyl.

Copper-Catalyzed Tandem O-Vinylation of Arylhydroxylamines/[3,3]-Rearrangement/Cyclization: Synthesis of Highly Substituted Indoles and Benzoindoles

Herein, we developed a copper-catalyzed O-vinylation of arylhydroxylamine using vinyliodonium salts as vinylation reagents to generate a transient O-vinyl-N-arylhydroxylamine that rapidly undergoes a [3,3]-sigmatropic rearrangement and subsequent cyclization/rearomatization to form a substituted indole. A wide range of highly substituted indoles and benzoindoles can be afforded in good yields. This approach is readily scalable, and the scope and application of this process are presented.

Metal-Free Multicomponent Construction of Tetrahydroisoquinoline-Indole Derivatives via In Situ Generated ortho-Quinonoid Intermediate

A metal- and ligand-free multicomponent coupling of tetrahydroisoquinoline (THIQ), ortho-hydroxybenzaldehydes and indoles under solvent-free conditions is described. The developed protocol provided a waste-free and concise access to C(1)-functionalized THIQ-indole derivatives under green conditions. The reactant molar ratio and neutral conditions were found crucial for controlling the selectivity of desired THIQ-indole product over competitive by-products i. e. oxazine and bis(indolyl)methane. The experimental and DFT study revealed the involvement of ortho-quinonoid species which reacts with indoles in situ to form THIQ-indole derivatives.

Access to 3-Oxindoles from Allylic Alcohols and Indoles

The site-selective and regioselective allylation of 2-substituted indoles was performed by using a ruthenium(IV) precatalyst containing a phosphine-sulfonate chelate. Mono-, di-, and triallylated indoles were selectively obtained depending on the reaction conditions with the formation of water as the only byproduct. The preparation of 3-oxindole derivatives was then successfully performed owing to air oxidation of the corresponding allylated indoles. Diallylated pseudoindoxyls were proven to be good synthons to perform cyclization through a ring-closing metathesis reaction to afford the corresponding tricyclic adducts. The photophysical properties of the 3-oxindoles were measured, and some of the compounds showed strong fluorescence in water.
