Editorial Review Dr. B.D. Bulchandani Associate Professor Department of Biotechnology, Sobhasaria Group of Institutions, Sikar, Rajasthan Technical University, Kota, India

Genetically Modified Crops - Editorial Review Why have genetically modified (GM) crops failed to be the popular success the scientists claimed them to be, few decades back? One can point out multiple reasons, ranging from technical issues related to ill effects or toxicity to genetic pollution to bio piracy issues, and also the social issues including their acceptance by traditional people in light of their fears, doubts and wide ranging apprehensions that are possibly hard to address, if not impossible. Although, the real reasons may be there to decipher and deliver, but the fact is that the promises have grown but their popularity in terms of fulfilment has not[1]. Despite twenty plus years of pro GM marketing campaign by powerful industry lobbies, supported by several scientific documentations in their favour, GM technology has only been taken up by a handful of countries, that too for a handful of crops. Figures and data from the GM industry indicate, that only five countries account for 90% of global GM cropland, and nearly all of these GM crops are belonging to either herbicide tolerant or pesticide producing plants. Meanwhile, rest of the regions of the world have resisted or have been hesitant in accepting them. Further, European consumers do not prefer consuming GM foods, and only a single type of GM maize is cultivated there. Major part of Asia is GM free, with the GM acreage in two large agricultural countries, i.e. India and China mostly accounted for by a non food crop i.e. cotton. Only three countries in Africa grow

any GM crops. In other precise words, GM crops are not 'feeding the world' as were claimed to do so at the dawn of twenty first century[2]. Not only was this technology supposed to make food and agriculture systems more efficient, simpler, safer, but GM crops have constantly being touted as the key to feed the exponentially growing population of world' and 'fighting climate change by producing strong, resistant crops, best suited for growing in harsh conditions[3]. In 1942, J.I. Rodale said, ‘One of these fine days, the public is going to wake up and will pay for food and eatables including, fruits, vegetables, meats, etc., according to how they were produced.’ Although this has been a low pace movement, the interest has been growing in leaps and bounds, and that day has finally arrived. With the growing health concerns and awareness, more and more people have understood that food matters, because right food is not less than medicine. The reasons for such disappointments may lie in the close and detailed critical studies in various parts of world that have not been encouraging and some have shown a dismal picture. No GM crops have been designed to deliver the motive of higher yields. Few instances, where yields have been enhanced, the gains to which a GM trait has then been added, have tended to come not from GM technology, but from the high quality varieties created through conventional breeding.

Isoenzyme Profiling of Polyphenoloxidase and Phenylalanine Ammonia Lyase in Cytoplasm of Lycopersicum esculentum in Response to Leaf Extract of Tagetes erecta (Marigold) Ankita Singh* Department of Biotechnology, Amity University, U.P., India

Abstract In the present study, the effect of leaf extracts of marigold (Tageteserecta) on the activity of Polyphenoloxidase (PPO) in Tomato (Lycopersicumesculentum) leading to the changes in the expression of the PR proteins Polyphenol oxidase (PPO) and Phenyl Ammonia Lyase (PAL) was evaluated. For this evaluation four sampling intervals were taken 0 hour, 24 hour, 48 hour and 72 hour.At the third node from base of each plant leaves were treated and samples from the distal untreated leaves were collected.The change in the activity of defense enzyme PPO and PAL and the expression of PPO isoforms was studied. The results demonstrate Seven acidic isoforms of PPO (Rf = 0.37, 0.5, 0.61, 0.65, 0.69, 0.71 and 0.74) could be observed in both control and marigold extract treated plants. Keywords: Lycopersicum esculentum, phenyl ammonia lyase, polyphenol oxidase, PR proteins, Tagetes erecta

INTRODUCTION Tomato(Lycopersicum esculentum) is one of the most popular and widely consumed vegetables grown worldwide. Popularity of the crop stems from its acceptable flavour, nutritive value (high in vitamin C and A), the short life cycle, and the high productivity. Marigold is an annual herb with pale-green leaves and golden yellow or orange flowers.[1-5] PR Proteins By changing their physiological conditions, higher plants protect themselves from various stresses such as pathogen attacks, wounding, application of chemicals including phytohormone and heavy metals, air pollutants like ozone, ultraviolet rays, and harsh growing conditions.[5-7] These protective reactions are known as "defense responses" of higher plants, and the proteins actively synthesized in accordance with this reaction are called "defense-related

proteins".[7-9]

Figure1.In particular, protective plant proteins specifically induced in pathological or related situations have been intensively studied from an agricultural perspective and are called "pathogenesis-related proteins" (PR proteins).

Paratransgenesis: Short Review Article Kalpesh Singh Department of Biotechnology, Amity University, U.P., India

Paratransgenesis is a system that endeavors to kill a pathogen from vector populaces through transgenesis of a symbiont of the vector. The objective of this system is to control vector-borne infections. The initial step is to distinguish proteins that keep the vector species from transmitting the pathogen. The qualities coding for these proteins are then brought into the symbiont, with the goal that they can be communicated in the vector. The last stride in the procedure is to bring these transgenic symbionts into vector populaces in nature.

Paratransgenesis aims at reducing vector competence by genetically manipulating symbionts. Transformed symbionts are spread maternally or via coprophagy across an insect population. Symbionts currently targeted in paratransgenesis include bacteria found within triatomine, tsetse fly, and mosquito tissues, and densoviruses infecting An. gambiae and Ae. aegypti mosquitoes. In order to perform paratransgenesis, there are several requirements: 

The primary case of this strategy utilized Rhodnius prolixus which is connected with the symbiont Rhodococcus rhodnii. R. prolixus is an imperative bug vector of Chagas' sickness that is brought about by Trypanosoma cruzi. The methodology was to architect R. rhodnii to express proteins, for example, Cecropin A that are dangerous to T. cruzi or that piece the transmission of T. cruzi. Vector transgenesis and paratransgenesis are novel methodologies that go for diminishing insect vectorial limit, or look to dispense with transmission of pathogens, for example, Plasmodium sp., Trypanosoma sp., and Dengue infection right now being produced. Vector transgenesis depends on direct hereditary control of sickness vectors making them unequipped for working as vectors of a given pathogen. Paratransgenesis concentrates on using hereditarily changed insect symbionts to express particles inside the vector that are harmful to pathogens they transmit.

  

The Symbiotic bacteria can be grown in vitro easily. They can be genetically modified, such as through transformation with a plasmid containing the desired gene. The engineered symbiont is stable and safe. The association between vector and symbiont cannot be attenuated. Field delivery is easily handled

Current information demonstrate that symbionts expressing molecules focusing on pathogen improvement can possibly lessen transmission in endemic districts, and seem random to any wellness load. As with transgenesis, spread of transformed symbionts also would benefit from the availability of a gene drive system to replace non-transformed symbionts present in natural vector populations.

Coalescent Theory Shivam Puri*, Manoj Srivastava Department of Biochemistry, Gautam Buddha University, U.P., India

Abstract Coalescent theory is broadly used to gauge population genetic parameters, for example, populace size, migration rates and recombination rates in a normal population. It was initially detailed as the "n-coalescent" by Kingman (1982). Others allude to it as the "Kingman coalescent" or simply the "coalescent". The coalescent model is gotten from a basic populace genetic model, and the most straightforward approach to comprehend what it is and how it functions is to follow the basic derivation. Keywords: coalescent theory, genetic parameters

INTRODUCTION Coalescent hypothesis is a review stochastic model of populace hereditary qualities that relates genetic assorted qualities in a specimen to demographic history of the populace from which it was taken. That is, it is a model of the impact of genetic drift, saw in reverse in time, on the family history of antecedents.[1] It involves a probabilistic evaluation of variety so as to normal parentage of alleles in a moderately small sample of people, from a much bigger populace. This incorporates thought of all pathways of inheritance through which inspected duplicates of a homologous DNA component are followed back to a solitary hereditary duplicate, known as the most recent ancestor (MRCA; additionally also termed the coancestor to underline the coalescent relationship). The inheritance connections among alleles are normally spoken to as a gene genealogy, or gene tree, comparative in structure to a phylogenetic tree.

assumptions shapes the premise of coalescent hypothesis. In light of recombination, diverse quality loci take after various pathways of parentage, bringing about various gene family histories. The coalescent is likewise pertinent to phylogenetics, as inadequate genealogy sorting between speciation events results in conflict among gene loci in phylogenetic connections construed among species. The numerical hypothesis of the coalescent was initially created in the mid 1980s by John Kingman.[2] In the easiest case, coalescent hypothesis accept no recombination, no natural selection, and no gene flow or populace structure. The gene parentage is free of the mutational procedure, such that adjustments in the DNA arrangement don't influence heredity and can be considered independently (regardless of the fact that all gene copies are indistinguishable in grouping they are not similarly related in the gene tree).[3,4] Under this model, the normal time between progressive blend occasions, by

The probabilistic desire of this gene family history is otherwise called the coalescent. Understanding the measurable properties of the coalescent under various

Genetic Recombination: A Review Punit Malhotra* Department of Biomedical Engineering, Jamia Millia Islamia, Delhi, India

Abstract Genetic recombination alludes to the process of recombining genes to deliver new gene arrangement that contrast from those of either parent. Genetic recombination produces genetic variety in living beings that repeat sexually. Genetic recombination happens as a consequence of the division of genes that happens amid gamete development in meiosis, the irregular joining of these genes at fertilisation, and the exchange of genes that happens between homologous chromosome sets in a procedure known as crossing over. Crossing over permits alleles on DNA molecules to change positions starting with one homologous chromosome fragment then onto the next. Genetic difference amongst individuals is achieved through genetic recombination. Keywords: crossing over, genetic diversity, genetic recombination

INTRODUCTION Genetic recombination is the production of offspring with mixes of traits/ genes that vary from those found in either parent. In eukaryotes, hereditary recombination amid meiosis can prompt a novel arrangement of hereditary data that can be passed on from one generation to another. Most recombination is normally happening. Amid meiosis in eukaryotes, genetic recombination includes the matching of homologous chromosomes. [1] This might be trailed by data exchange between the chromosomes. The data exchange may happen without physical trade (a segment of hereditary material is duplicated starting with one chromosome then onto the next, without the giving chromosome being changed; or by the breaking and rejoining of DNA strands, which frames new atoms of DNA.[2,3]

this situation, new blends of alleles are not delivered subsequent to the sister chromosomes are typically indistinguishable. In meiosis and mitosis, recombination happens between comparable particles of DNA (homologs). In meiosis, non-sister homologous chromosomes pair with each other so that recombination distinctively happens between non-sister homologues. In both meiotic and mitotic cells, recombination between homologous chromosomes is a typical system utilized as a part of DNA repair.[4] Genetic recombination and recombinational DNA repair likewise happens in microscopic organisms and archaea, which use asexual mode of multiplication. Recombination can be misleadingly impelled in research facility (in vitro)

Recombination may likewise happen amid mitosis in eukaryotes where it customarily includes the two sister chromosomes framed after chromosomal replication. For
