Defense to in groundnut ( L.) is associated with vascular tissue compactness and expression of genes coding for pathogenesis-related (PR) proteins.

Unlabelled: is the causal agent of stem rot of many crops, a highly destructive disease of groundnut ( L). Based on evidence that many groundnut genotypes have an inherent ability to tolerate the pathogenicity of species, twenty-two genotypes of groundnut were screened against infection in sick plot field experiment; four genotypes, namely CS19, GG16, GG20 and TG37A, were selected as being the most tolerant, moderately tolerant, susceptible and highly susceptible to stem rot, respectively. Stem tissues (1cm from the collar region) from infected and healthy plants of four selected genotypes differing in susceptibility were examined using a scanning electron microscope (SEM).

Optimizing raffinose family oligosaccharides content in plants: A tightrope walk.

Plants synthesize various compounds for their growth, metabolism, and stress mitigation, and one such group of compounds is the raffinose family of oligosaccharides (RFOs). RFOs are non-reducing oligosaccharides having galactose residues attached to a sucrose moiety. They act as carbohydrate reserves in plants, assisting in seed germination, desiccation tolerance, and biotic/abiotic stress tolerance.

A Rare Case of Systemic Lupus Erythematosus With Diffuse Alveolar Hemorrhage and Guillain-Barre Syndrome.

Systemic lupus erythematosus (SLE) is an autoimmune systemic disease with many organ involvements with high morbidity and mortality percentage. It's unusual for systemic lupus erythematosus (SLE) to present with diffuse alveolar hemorrhage (DAH) as the earliest presentation. Diffuse alveolar hemorrhage (DAH) refers to the effusion of blood into the alveoli due to damaged pulmonary microvasculature.

Spatio-temporal expression pattern of Raffinose Synthase genes determine the levels of Raffinose Family Oligosaccharides in peanut (Arachis hypogaea L.) seed.

Raffinose family oligosaccharides (RFOs) are known to have important physiological functions in plants. However, the presence of RFOs in legumes causes flatulence, hence are considered antinutrients. To reduce the RFOs content to a desirable limit without compromising normal plant development and functioning, the identification of important regulatory genes associated with the biosynthetic pathway is a prerequisite.

Gold(I)-Catalyzed Synthesis of Heterocycles via Allene Oxide from Propargylic Alcohols.

A new mechanistic pathway of propargylic alcohol activation by gold(I) catalysis has been proposed toward the efficient synthesis of N-protected pyrroles, 5,6-dihydropyridin-3(4)-ones from N-protected 5-aminopent-2-yn-1-ol, and 5-aminopent-2-yn-1-ol. Control experiments support that the reaction proceeded via the neighboring group participation of the oxygen atom of propargylic alcohol to form an allene oxide intermediate where the nucleophilic heteroatom attacks intramolecularly. Further, this methodology is successfully extrapolated toward the atom-economic synthesis of hydroxyalkyl indoles and benzofurans.

Progress and prospects of C trait engineering in plants.

Incorporating C photosynthetic traits into C crops is a rational approach for sustaining future demands for crop productivity. Using classical plant breeding, engineering this complex trait is unlikely to achieve its target. Therefore, it is critical and timely to implement novel biotechnological crop improvement strategies to accomplish this goal.

Sequencing and de novo transcriptome assembly for discovering regulators of gene expression in Jack (Artocarpus heterophyllus).

Jack (Artocarpus heterophyllus) is a multipurpose fruit-tree species with minimal genomic resources. The study reports developing comprehensive transcriptome data containing 80,411 unigenes with an N50 value of 1265 bp. We predicted 64,215 CDSs from the unigenes and annotated and functionally categorized them into the biological process (23,230), molecular function (27,149), and cellular components (17,284).

Metabolic profiling for dissection of late leaf spot disease resistance mechanism in groundnut.

Unlabelled: Late leaf spot (LLS) caused by fungi is generally more destructive and difficult to control than early leaf spot. The aim of this study was to decipher biochemical defense mechanism in groundnut genotypes against by identifying resistance specific biomarkers and metabolic pathways induced during host-pathogen interaction. Metabolomics of non-infected and infected leaves of moderately resistant (GPBD4 and ICGV86590), resistant (KDG128 and RHRG06083) and susceptible (GG20, JL24 and TMV2) genotypes was carried out at 5 days after infection (65 days after sowing).

Phytohormone signalling and cross-talk to alleviate aluminium toxicity in plants.

Aluminium (Al) is one of the most abundant metals in earth crust, which becomes toxic to the plants growing in acidic soil. Phytohormones like ethylene, auxin, cytokinin, abscisic acid, jasmonic acid and gibberellic acid are known to play important role in regulating Al toxicity tolerance in plants. Exogenous applications of auxin, cytokinin and abscisic acid have shown significant effect on Al-induced root growth inhibition.

Distinguish metabolic profiles and defense enzymes in leaf blight resistant and susceptible genotypes of groundnut.

Alternaria leaf blight is major fungal disease of summer groundnut, causes significant loss of haulm and pod yield. Aims of this study were to understand the role of metabolites and phenylpropanoid related enzymes in leaf blight resistance and to find out metabolic marker for disease resistance. leaf blight resistant (GPBD4 and CS186) and susceptible genotypes (GG2 and TPG41) of groundnut were grown in pots during -summer 2015.

Nutritional composition and antioxidant activity of Spanish and Virginia groundnuts (Arachis hypogaea L.): a comparative study.

Kernels of sixty groundnut genotypes comprising thirty each of Spanish and Virginia groups were characterized and compared for the content of oil, protein, phenols and antioxidant activity along with their fatty acid and sugars profiles. The antioxidant activity for Virginia genotypes was ranged from 12.5 to 16.

Quality traits of Indian peanut cultivars and their utility as nutritional and functional food.

Peanut (Arachis hypogaea L.) is considered as a highly nutritious foodstuff. Of late, the importance of peanut as a functional food has been growing.

Outcome of temporary silicone oil tamponade in complex rhegmatogenous retinal detachment.

Purpose: To evaluate the anatomic and visual outcomes and complications of temporary silicone oil (SO) retinal tamponade in patients with complex rhegmatogenous retinal detachments (RD).

Methods: The retrospective study included 100 eyes of 93 consecutive patients. Indications for the use of SO were proliferative vitreoretinopathy (PVR) (30 eyes), difficult RD (30 eyes), giant retinal tears (17 eyes), RD after penetrating trauma (14 eyes), and macular holes in highly myopic eyes (9 eyes).
