Evaluation of Antimicrobial Efficacy of Silver Nanoparticles Synthesized from Punica gratum Extracts N.A. Tambe*, P.M. Tumane Department of Microbiology, L.I.T. Campus, R.T.M.N. University, Amravati Road, Nagpur, India

Abstract Nanotechnology is a branch of science which has open many routes of technologies. With the rapid development of nanotechnology, application has been extended further and now silver is the engineered nanomaterial most commonly used in consumer products. Green nanotechnology is an area with significant focus at present on the important objective of facilitating the manufacture of nanotechnology-based products that are eco-friendly and safer for all beings, with sustainable commercial viability. In the present study, we have used a green route for the synthesis of silver nanoparticles by using plant extracts of Punica gratum. These eco-friendly Ag-NPs were characterized by UV–Vis spectrophotometery which exhibited maximum absorbance in specific nanometre range in UV–Vis spectroscopy. Further characterization was confirmed by TEM, FTIR, X-RD analysis and LM-20 analysis. The antimicrobial activity of synthesised nanoparticles from Punica gratum shows its efficacy to be a good antimicrobial agent. Keywords: antimicrobial assay, characterization studies, Punica gratum, silver nanoparticles

INTRODUCTION Nanotechnology deals with the progress in experimental methods for the production of nanoparticles of various sizes, shapes and controlled dispersity.[1] Nanoparticles exhibit completely new or improved properties based on specific characteristics such as size, distribution and [2] morphology. Nanoparticles are of immense scientific relevance as they connect the gap between bulk materials and atomic or molecular structures.[3] Silver has been special place in the history of the elements because it is one of the first five metals discovered and used by humans.[4] Ag-NPs have particular properties that may perhaps have numerous applications in the fields of dentistry, clothing, catalysis, mirrors, optics, photography, electronics, and the food industry.[5] Plants and fruit extracts

can be described as nano-factories which provide potential pathway to bioaccumulation into food chain and environment.[6] Biological synthesis of silver nanoparticles by using plants, microorganisms and enzymes, etc. have been suggested as more eco-friendly possible alternatives than using physical and chemical methods,[7] silver nanoparticles (Ag-NPs) have a wide area of interest, as they have a large number of applications, such as in nonlinear optics, spectrally selective coating for solar energy absorption, bio-labelling, intercalation materials for electrical batteries as optical receptors, catalyst in chemical reactions, and as antibacterial capacities. The medical properties of silver have been known for over 2,000 years. Since the nineteenth century, silver-based

Short Review Article: Defence Enzyme-Polyphenol Oxidases (PPO) in Lycopersicum esculentum (Tomato) Ankita Singh* Department of Biotechnology, Amity University, U.P., India

Abstract Tomato (Lycopersicum esculentum) is one of the most important horticultural crops in the world. In India, tomato is considered as first rank vegetable crop because of its more use. The action of Polyphenol Oxidases (PPO) on phenolic oxidation has a role to play in the plant’s defense. This is a short review article on the mechanism and role of PPO in tomato. Keywords: Lycopersicum esculentum, phenolic oxidation, polyphenol oxidase

INTRODUCTION Tomato ((Lycopersicum esculentum) ) is widely in use throughout the world, due to its various properties, such as, it is easily processed; the plants can be propagated by seed or cloned by tip or shoot cuttings; the plants have a high yield of fruit; there is reasonable biomass and protein content; and they are easily grown under containment. Its production is very concentrated in semi-arid regions. The presence of endogenous defense mechanism, such as, the oxidative enzyme, Polyphenol Oxidase (PPO), is generally produced as a reaction to pathogens. It catalyzes the formation of lignin and other oxidative phenols that cause the development of defense barriers, as shown in figure 1.[1-3]

Browning of the cut surface of some fruits and vegetables is due to the presence of a group of enzymes called polyphenol oxidases. These enzymes are released by the broken cells and they catalyze the reaction between colorless molecules called polyphenols and molecular oxygen. This reaction creates colored compounds and these new compounds can spontaneously cross react with one another to form black-brown complexes called melanins.[2,5] Polyphenol oxidases (PPOs) (E.C. 1.10.3.2) are ubiquitous copper-containing enzymes which use molecular oxygen to oxidize common ortho-diphenolic compounds such as caffeic acid and catechol to their respective quinones. PPOgenerated quinones are highly reactive and may cross-link or alkylate proteins, leading to the commonly observed brown pigments in damaged plant tissues and plant extracts.[3,4]

Drought Tolerance in Pearl Millet- I Riva Mathur* Department of Biotechnology, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Rajasthan, India

Abstract Stress tolerance has long fascinated plant biologists as a challenge to understand the mechanism of plant survival under biotic and abiotic stress conditions. Exposure of plants to abiotic stresses, such as high salinity, drought, extreme light and temperature leads to major loss in crop productivity. Pearl millet is one such crop that has been facing drought conditions and less productivity of the crop. This article is a short review on the different stresses and their effect on crop productivity. Keywords: abiotic stress, drought conditions, crop productivity, pearl millet

INTRODUCTION Plant growth and productivity is adversely affected by nature’s wrath in the form of various biotic and abiotic stress factors. Abiotic stresses, such as drought, salinity, extreme temperatures, chemical toxicity and oxidative stress are serious threats to agriculture and the natural status of the environment. Exposure of these plants to these abiotic stresses leads to major loss in crop productivity.[1] All forms of abiotic stress affect the water relations of a plant on the cellular as well as whole plant level causing specific as well as unspecific reactions, damages and adaptation reactions.[2] Environmental stresses trigger a wide variety of plant responses, ranging from altered gene expression and cellular metabolism to changes in growth rate and plant productivity. Water deficit (drought conditions) can be defined as the absence of adequate moisture necessary for a plant to grow normally and complete its life cycle. Water deficit is one of the major abiotic stresses, which adversely effects the crop growth and yield. Generally drought stress occurs when the available water in the soil is not available and atmospheric conditions cause continuous loss of water by transpiration and evaporation. Drought stress tolerance is seen in almost all plants but its extent varies from species to species and even within species. Water deficit

and salt stresses are global issues to ensure survival of agricultural crops and sustainable food production.[3] Drought stress is considered to be a moderate loss of water, which leads to stomatal closure and limitation of gas exchange. Desiccation is much more extensive loss of water, which can potentially lead to gross disruption of metabolism and cell structure and eventually to the cessation of enzyme catalyzed reactions.[4] Drought stress is characterized by reduction of water content, diminished leaf water potential and tugger loss, closure of stomata and decrease in cell enlargement and growth. Severe water stress may result in the arrest of photosynthesis, disturbance of metabolism and finally the death of plant.[5] It has been established that drought stress is a very important limiting factor at the initial phase of plant growth and establishment. It affects both elongation and expansion growth.[6] Water stress greatly suppresses cell expansion and cell growth due to the low turgor pressure. Osmotic regulation can enable the maintenance of cell turgor for survival to assist plant growth under severe drought conditions in pearl millet.[7]

Effect of Drought Stress on Morphological Characteristics in Plants- II Riva Mathur* Department of Biotechnology, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Rajasthan, India

Abstract Drought conditions significantly affect the growth and development of plants. Various metabolic functions in plants are also reduced due to such conditions, such as reduction in plant pigments- chlorophyll and carotenoids and alterations in the expression of certain proteins. This is a brief review on various effects of drought stress on different morphological characteristics in plants. Keywords: carotenoids, chlorophyll content, crop productivity, drought stress, protein profiling

INTRODUCTION Drought is an important limiting factor at a initial stage. It affects both elongation and expansion phases. Among the crops, rice as a submerged crop, is probably susceptible to drought. Pearl millet is comparatively more drought tolerant than other cereal crops. In experimental studies, it was observed that the stem length of soybean decreased under water deficit conditions. While, in other studies, it was found that the plant height reduced upto 25% in water stressed citrus seedlings. Though, osmotic regulation can enable the maintenance of cell turgor for survival or to assist plant growth under severe drought conditions in pearl millet.[1-3] Water stress suppresses cell expansion and cell growth due to low turgor pressure. The reduction in plant height is associated with a decline in cell enlargement and enhanced leaf senescence under water stress.[4,5] Development of optimal leaf area is important to photosynthesis and dry matter production. The significance of root system in obtaining water has for some time been

observed. A productive root system can aid in plant growth and development amid the early plant development stage and obtain water from shallow soil layers that is generally lost by dissipation in legumes.[3,5] The improvement of root system builds the water uptake and keeps up required osmotic pressure. An increase in root to shoot ratio under drought conditions has also been found to be related to ABA content of roots and shoots. [6] Increased plant fresh and dry weights in water drought conditions are required features. A usual disadvantage of water drought condition on harvest plants is the decrease in fresh and dry biomass production.[7] Plant productivity under water drought condition is firmly identified with the procedures of processes of dry matter partitioning and temporal mass distribution.[2,3]

Properties of Tagetes erecta (Marigold): Short Review Article Ankita Singh* Department of Biotechnology, Amity University, U.P., India

Abstract Marigold is an annual herb with pale-green leaves. Flowers in this plant are produced from the beginning of summer until frost and have a strong but rather unpleasant odor. It also has anti- inflammatory properties and used in the healing of wounds. This is a brief review article on the different properties of the plant Tagetes erecta (marigold). Keywords: Tagetes erecta, properties

INTRODUCTION The genus Tagetes belongs to the Asteraceae family and comprises of 56 species, 27 of them annuals and 29 perennials. Tagetes sp. are grown all over the world as multi-purpose plants of these species. T. minuta, T. erecta, T. patula and T. tenuifolia, are some of the most common species.[1] Tagetes sp. have been used in folk medicine to treat intestinal and stomach diseases and some of them have been found to possess biological activity.[2] This genus is recognized as a source of very interesting biologically active products, that is, carotenoids used as food colorants and feed additives[3] and possessing anticancer and anti-ageing effects[4], essential oils known for their antibacterial and insecticidal properties[5] and flavonoids having pharmacological properties.[6] Volatile oils of T. minuta are used as antibacterial (Senatore et al., 2004), flavour components in food products and as perfumes.[1] They also have suppressive biological activity against some insects and pathogens.[7] Tagetes erecta is a potential plant whose essential oil from flowers has acted as an effective repellent against insects.[8]

Tagetes minuta oil has been found to be active against carnation ring spot (CaRSV) and carnation vein mottle viruses (CaVMV). According to WHO survey, 80% populations living in the developing countries rely almost exclusively on traditional medicine for their primary health care needs and pest control. Exploration of chemical constituents of different parts of the plants and pharmacological screening may provide us the basis for new leads for development of novel agents. Crushed roots of marigold (Tagetes erecta) provide good control of root knot nematodes when applied to soil in mulberry gardens. Some species in Tagetes have been widely used as natural insecticides and fungicides. For example, the extract from the roots of T. erecta was lethal or inhibitory to the hatching of Meloidogyne javanica (Treub) chitwood and M. arenaria (Neal) Chitwood. The extracts from some species in Tagetes L. also exhibit anti-fungicidal activity. Various oils in plants of Tagetes L. have been found to inhibit Gram-positive bacteria and fungi. In addition, flower pigments in the plants of Tagetes L., as
