Comparative Analysis of Various Strains of Plant Growth Promoting Rhizobacteria on the Physiology of Garlic (Allium sativum)

Garlic is a most important medicinal herb belonging to the family Liliaceae. Both its leaves and bulb are edible. The current study was based on evaluating the growth promoting potential of plant growth promoting rhizobacteria (PGPR) on garlic (Allium sativum L.) growth and biochemical contents. Garlic cloves were inoculated with 3 kinds of PGPRs, Pseudomonas putida (KX574857), Pseudomonas stutzeri (Kx574858) and Bacillus cereus (ATCC14579) at 108 cells/mL prior to sowing. Under natural conditions, plants were grown in the net house. The PGPR significantly enhanced % germination, leaf and root growth and their biomass also increased the diameter of bulb and fresh and dry weight. The flavonoids, phenolics, chlorophyll, protein and sugar content were also significantly increased due to PGPR inoculation. The Pseudomonas stutzeri was found most effective for producing longer leaves with moderate sugar, high flavonoids (129%) and phenolics (263%) in bulb over control (Tap). The Pseudomonas putida exhibited a maximum increase in bulb diameter and bulb biomass with maximum phenolics and flavonoid contents.

Biological Synthesis of Nanoparticles and Their Applications in Sustainable Agriculture Production

Nanotechnology is a developing field in biotechnology. The synthesis of nanoparticles is an important step in the field of nanotechnology. Overcoming the limitations of traditional methods, a green scheme for synthesizing nanoparticles has emerged. Plants and microorganisms are mainly used for the green synthesis of metal nanoparticles. Some of the nanoparticles showed strong antimicrobial effects against different plant pathogens. Compared with microorganisms, the use of plants to synthesize nanoparticles is on the rise, and has advantages compared with microorganisms, because plants have a wide range of bio-molecular variability, which can act as blocking/stabilizing agents and reducing agents, thereby increasing reduction rate and stability of synthetic nanoparticles. Of all living things, plants seem to have the best potential for nanoparticle biosynthesis and are suitable for large-scale biosynthesis. Compared with microorganisms, the synthesis of plant-derived nanoparticles is faster and more stable. Therefore, this review focuses on the use of microbial and plant sources to synthesize nanoparticles and their applications in agriculture.

Antihyperglycemic effect of methanol extract of Tamarix aphylla L. Karst (Saltcedar) in streptozocin–nicotinamide induced diabetic rats

Objective: To evaluate the antihyperglycemic potential of Tamarix aphylla(T. aphylla)leaves in STZ–NIC induced diabetes in Wister Albino rats.Methods: Acute toxicity study was done to check the toxicity of T. aphylla(L. Karst)methanol extract. T. aphylla leaves extract was administered intraperitoneally(100 mg,250 mg and 400 mg/kg body weight per day) to diabetic Wister rats for 21 days. The various parameters were studied including fasting blood glucose levels, haemoglobin and glycosylated haemoglobin.Results: The treatment groups with the extract at three dose levels expressively abridged the intensities of blood glucose and Glycosylated Haemoglobin. The earlier detected reduced level of plasma haemoglobin of the diabetic rats was raised to near normalcy with treatment of extract.Conclusions: The results of the current study confirm that the leaves extract of T. aphylla are nontoxic and have antidiabetic nature.

Soft Robotic Glove Controlling Using Brainwave Detection for Continuous Rehabilitation at Home

The patients with brain diseases(e.g.,Stroke and Amyotrophic Lateral Sclerosis(ALS))are often affected by the injury of motor cortex,which causes a muscular weakness.For this reason,they require rehabilitation with continuous physiotherapy as these diseases can be eased within the initial stages of the symptoms.So far,the popular control system for robot-assisted rehabilitation devices is only of two types which consist of passive and active devices.However,if there is a control system that can directly detect the motor functions,it will induce neuroplasticity to facilitate early motor recovery.In this paper,the control system,which is a motor recovery system with the intent of rehabilitation,focuses on the hand organs and utilizes a brain-computer interface(BCI)technology.The final results depict that the brainwave detection for controlling pneumatic glove in real-time has an accuracy up to 82%.Moreover,the motor recovery system enables the feasibility of brainwave classification from the motor cortex with Artificial Neural Networks(ANN).The overall model performance reveals an accuracy up to 96.56%with sensitivity of 94.22%and specificity of 98.8%.Therefore,the proposed system increases the efficiency of the traditional device control system and tends to provide a better rehabilitation than the traditional physiotherapy alone.

Antimicrobial and Antioxidant Activities of Methanolic Extract and Fractions of <i>Epilobium roseum</i>(Schreb.) against Bacterial Strains

Present study aims to evaluate antimicrobial and antioxidant activities of the crude methanolic extract and different fractions of the Epilobium roseum (Schreb). The extract and fractions were used against pathogenic bacteria (Bacillus subtilis, Bacillus atrophaeus, Klebsiella pneumonia and Pseudomonas aeruginosa) and fungal strains (Aspergillus niger and Aspergillus flavus). The methanolic extract and their sub fraction n-hexane showed a prominent inhibition zone against all bacterial strains but inactive against fungal strains. The various extracts of Epilobium roseum (Schreb) from various parts were tested for their antioxidant activity by 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assay. The IC50 of the stem and root of methanolic extract and their sub fraction n-hexane showed best activity ranged between 22.73 ± 6.92, 21.49 ± 6.26 and 14.94 ± 3.54, 13.92 ± 1.04 μg/ml compared to another fraction. The results support that Epilobium roseum can be used as antimicrobial and antioxidant agents. The results support the present study that Epilobium roseum (Schreb) has a potential source of natural antibacterial, antifungal and antioxidant potentials.

Genetic Variation among Seedling of Pumpkins Genotypes through SDS-Page

Genetic diversity in 30 genotypes of Pumpkins was collected from unexplored mountainous areas of Khyber Pakhtunkhwa, Pakistan was investigated through biochemical characterization. For biochemical characterization, Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis was carried out. The seed proteins were resolved on 7.5% and 15% polyacrylamide gel. A total of 35% genetic disagreement was observed in the collected lines with linkage distances ranging from 0.00 - 0.83 (percent disagreement). Similarly, cluster analysis sorted total germplasm on the basis of 12 bands (total bands) into eight clusters. Present study revealed a considerable amount of genetic diversity explored in pumpkin germplasm, Cluster analysis exhibited moderate level of genetic diversity;to broaden the gene pool. Further collection of the important germplasm is needed to be used in the development of improved cultivars with respect to quality and quantity.

Physiological Evaluation of Wheat (<i>Triticum aestivum</i>L.) Genotypes at Pre-Anthesis Stage under Heat Stress Conditions

Experiments were conducted to analyze effects of high temperature stress on wheat at pre-anthesis growth stage. Twenty four wheat genotypes exposed to a sub optimal temperature (>35°C) which showed altered physiological, biochemical and agronomic characteristics. Accumulation of proline, presence of new protein bands and higher antioxidant enzyme activity in leaves of G.7 and G.17 reflects their better adaptive response under heat stress conditions. G.17 and G.19 showed least reduction in number of spikelets per spike, biological yield and 100 grain weight. It was inferred that the genotypes G.7, G.17 and G.19 exhibited greater heat tolerance and could be recommended for cultivation under heat stress conditions.
