Aromatic Metamorphosis of Indoles into 1,2-Benzazaborins

Among the plethora of aromatic compounds, indoles represent a privileged class of substructures that is ubiquitous in natural products and pharmaceuticals. While numerous exocyclic functionalizations of indoles have provided access to a variety of useful derivatives, endocyclic transformations involving the cleavage of the C2-N bond remain challenging due to the high aromaticity and strength of this bond in indoles. Herein, we report the aromatic metamorphosis of indoles into 1,2-benzazaborins via the insertion of boron into the C2-N bond. This endocyclic insertion consists of a reductive ring-opening using lithium metal and a subsequent trapping of the resulting dianionic species with organoboronic esters. Considering that 1,2-azaborins have attracted increasing academic and industrial attention as BN isosteres of benzene, the counterintuitive aromatic metamorphosis presented herein can feasibly be expected to substantially advance the promising chemistry of 1,2-azaborins.

ERF Gene Clusters: Working Together to Regulate Metabolism

Plants produce structurally diverse specialized metabolites, including bioactive alkaloids and terpenoids, in response to biotic and abiotic environmental stresses. The APETALA2/ETHYLENE RESPONSE FACTOR (AP2/ERF) family of transcription factors (TFs) play key roles in regulating biosynthesis of specialized metabolites. Increasing genomic and functional evidence shows that a subset of the ERF genes occurs in clusters on the chromosomes. These jasmonate-responsive ERF TF gene clusters control the biosynthesis of many important metabolites, from natural products, such as nicotine and steroidal glycoalkaloids (SGAs), to pharmaceuticals, such as artemisinin, vinblastine, and vincristine. Here, we review the function, regulation, and evolution of ERF clusters and highlight recent advances in understanding the distinct roles of clustered ERF genes and their possible application in metabolic engineering.

Physiological and transcription analyses reveal the regulatory mechanism of melatonin in inducing drought resistance in loquat (Eriobotrya japonica Lindl.) seedlings

Drought limits the growth and development of loquat (Eriobotrya japonica Lindl.) seedlings. Although melatonin (MT) is a naturally occurring small molecule in plants and has been linked with response to drought stress, the underlying mechanism remains largely unknown. The protective effects and regulatory mechanisms of MT on the regulation of drought stress in grafted loquat seedlings were analyzed in this study. The physiological results showed that MT effectively mitigated chlorophyll degradation and malondialdehyde (MDA) accumulation in the loquat leaves under drought stress. In addition, MT improved the photosynthetic efficiency and starch content of grafted loquat seedlings. Transcriptome results revealed that MT regulated genes involved in the Ca2+ signal transduction (cyclic nucleotide gated channel, CNGCs and cam modulin/ calmodulin-like protein, CAM/CMLs), starch and sucrose metabolism (sucrose synthase, SuS5 and SuS6), and plant hormone signal transduction (ABA receptor, PYL4; protein phosphatase 2C, PP2Cs; auxin/indole acetic acid protein, AUX/IAAs and ethylene responsive transcription factor 1B, ERF1B), and the transcription factors such as WRKYs, NACs, ERFs, and bHLHs. We highlighted the analysis on phytohormone signaling pathways and their possible crosstalk. The results also demonstrated that MT increased the endogenous MT, IAA and CTK contents, while decreasing the ABA content under drought condition. Taken together, these results provided a new perspective on the role of MT in drought stress and a network for gene function analysis in MT-mediated signaling pathways.

Mesobacillus aurantius sp. nov., isolated from an orange-colored pond near a solar saltern

An endospore producing, strict aerobic, Gram-stain-positive, orange-colored colony forming bacterium designated as strain JC1013(T) was isolated from an orange pond near a solar saltern of Tamil Nadu, India. Phylogenetic analysis of the 16S rRNA gene sequences indicated that strain was affiliated to the family Bacillaceae of the phylum Firmicutes. Strain showed highest 16S rRNA gene sequence identity of 98.7% with Mesobacillus selenatarsenatis SF-1( T) and below 98.3% with other members of the genus Mesobacillus. Strain JC1013(T) produced carotenoid pigments and indole compounds. Major cellular fatty acids of strain JC1013(T) were iso-C-15:0,C- anteiso-C-15:0, C-16:0 3-OH, iso-C-17:0 omega 10c and summed feature 4 (iso-C-17:1 I/ anteisoB). Polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and four unidentified phospholipids. Strain JC1013(T) constituted m-diaminopimelic acid as diagnostic cell wall amino acids. MK-7 is the predominant menaquinone of strain JC1013(T). The genome size of strain JC1013(T) was 4.6 Mbp and its G + C content was 42.7 mol%. For the affirmation of strain’s taxonomic status, a detailed phylogenomic study was done. Based on the phylogenetic analyses, low ANI (84.6%), AAI (88.5%) values, in-silico DDH (< 29%) value, morphological, physiological and chemo-taxonomical characteristics, strain JC1013(T) was clearly distinguished from the nearest phylogenetic neighbor, Mesobacillus selenatarsenatis SF-1(T) to conclude that it is a new species of the genus Mesobacillus. We propose the name as Mesobacillus aurantius with type strain JC1013(T) (= NBRC 114146(T) = KACC 21451( T)).

Enantioselective Allylation of Indoles: A Surprising Diastereoselectivity

Herein we show a novel approach toward the allylation of indoles. Thereby, we explore a class of bench-stable allylboronates and fine-tune their reactivity. The allylations of different substituted indoles proceed with negligible diastereo- and excellent enantioselectivities. This surprising selectivity (up to 99:1 er, up to approximate to 60:40 dr) is rationalized by DFT calculations.

Strong-field ionization of complex molecules

Strong-field photoelectron momentum imaging of the prototypical biomolecule indole is disentangled in a combined experimental and computational approach. Experimentally, strong control over the molecules enables the acquisition of photoelectron momentum distributions in the molecular frame for a well-defined narrow range of incident intensities. A highly efficient semiclassical simulation setup based on the adiabatic tunneling theory quantitatively reproduces these results. Jointly, experiment and computations reveal holographic structures in the asymptotic momentum distributions, which are found to sensitively depend on the alignment of the molecular frame. We identify the essential molecular properties that shape the photoelectron wave packet in the first step of the ionization process and employ a quantum-chemically exact description of the cation during the subsequent continuum dynamics. The detailed modeling of the molecular ion, which accounts for its polarization by the laser electric field, enables the accurate description of the photoelectron dynamics in close vicinity of the molecule. Our approach provides full insight into the photoelectron’s dynamics in terms of semiclassical trajectories and aims at the simulation and unraveling of strong-field diffractive imaging of biomolecular systems on femtosecond timescales.

Impacts of dietary supplementation with p-coumaric acid and indole-3-acetic acid on survival and biochemical response of honey bees treated with tau-fluvalinate

Pollinator populations are in decline worldwide. Multiple factors have been cited as potential causes to these declines. In honey bees, a combination of stressors is known to cause colony losses. Adequate nutrition is a key factor for honey bee growth and colony development. Several studies show that the nutritional quality of the diet is directly proportional to the ability of the bee to face challenges or stressors. We explored the effect of p-coumaric (600 mu M) and indole-3-acetic acid (2, 20 or 200 mu M) supplementation on the survival and activity of key detoxification enzymes of honey bees exposed to tau-fluvalinate. The dietary supplementation with p-coumaric and indole-3-acetic acids (20 mu M) enhanced the survival of bees exposed to tau-fluvalinate (approximately 20%). We also showed that dietary p-coumaric acid increased the levels of cytochrome P450 and glutathione reductase activity in bees treated with tau-fluvalinate, as well as in the untreated controls, while glutathione-S-transferase activity was lower in treated bees than in untreated. In bees fed with indole-3-acetic acid, cytochrome P450 showed increased levels, however, glutathione-S-transferase showed the lowest activity. Moreover, the results showed that supplementation with p-coumaric and indole-3-acetic acids did not alter acetyl cholinesterase activity, nor did treatment with tau-fluvalinate. Altogether, the enzymatic changes related to the detoxification mechanisms observed in bees that were fed with p-coumaric and indole-3-acetic acids could be responsible for the increased survival of bees treated with tau-fluvalinate compared to those that received a control diet. The results presented in this study, together with previous studies, provide evidence of the importance of dietary phytochemicals in the response of honey bees to pesticide exposure. Moreover, these results are the first report of the beneficial effect of the phytohormone indole-3-acetic acid on the survival of honey bees treated with tau-fluvalinate.
