These compounds produced by living organisms are patented and used for commercial activities 100 mg azithromycin mastercard. As a result of this 100mg azithromycin overnight delivery, the farmers who cultivate the crop are being deprived of their rightful claims and compensations azithromycin 500mg free shipping. The genetic resources of the developing nations are over exploited by the rich nations. For instance, Basmati rice is a crop grown indigenously in India from a very long time. A the Government had granted a patent to cover the entire basmati rice plant so that other countries or institutions cannot undertake any other research programmes pertaining to Basmati plant. Pentadiplandra brazzeana, a native plant of West Africa, produces a protein called brazzein. Richer nations are over exploiting the commercial resources of the developing countries without adequate compensation. With advances in scientific equipments, instruments and techniques, the biodiversity of the poor and developing nations of the tropics are overused and exploited by the rich nations. There is a growing awareness of this over exploitation and hence the developing countries are enacting legislative laws to prevent this over exploitation by the rich nations. Bio-patent The emergence of modern biotechnology has brought forth many legal characterizations and treatment of trade related biotechnological processes and produces, popularly described as Intellectual Property. Intellectual property includes patents, trade secrets, copy rights and trade marks obtained for processes and products created through ones own knowledge and research. The right to protect this property prohibits others from making copying using or selling these processes and products. The plant breeder who developed this new variety enjoys the exclusive right for marketing the variety. Patenting of important crops and animal breeds may bring down a shortfall in genetic resources. One of the major negative aspects of bio- 247 patency is that it may lead to scarcity of genetic resources. In addition, majority of the people may not have access to certain rare genetic resources protected by Bio-patency laws. People argue that giving patent rights to transgenic plants and transgenic animals is a wrongful idea as these patents will work as impediments in free exchange of genetic materials for improvement of crops and livestock. Intellectual Property Rights may also adversely affect the following: Food security, use of evolved agricultural practices, biological diversity and ecological balance and livelihood of the poor in developing countries. Patents The Indian Patent Act of 1970 allows process patents, but no product patents for foods, chemicals drugs and pharmaceuticals. Patents are granted as per the law of the State and are also disputed in the court of Law whenever complaints of infringement of the patents are violated by the people. In 1980, the discovery of an oil eating bacterium (Pseudomonas) by a non-resident Indian Scientist (Dr. Sustained agriculture Increased food production in India was made possible by the employment of modern technology in agriculture. The increase in the productivity is mainly due to rapid rise in overall area under cultivation of cereals. To maintain the crops and productivity, we have to expand irrigation facilities and use large amounts of fertilizers and pesticides. Due to degeneration in soil fertility, the traditional varieties of crop plants as cultivated in earlier periods got disappeared or are on the brink of extinction. Our agriculture is slowly being converted into an unsustainable system in the years to come, as the cost of chemicals and fertilizers, labour, cost of seeds are going to make the agricultural products costlier. Hence, to remedy this situation, we will have to find alternative permanent arrangements in sustainable agriculture. To protect the interest of the farmers on their agricultural lands and capital investments, sustainable agriculture which is the best source of alternative method should be compulsorily taken up and practiced by the traditional farmers. Sustainable agriculture can be carried on without any threat to our soils, environment, plants and animal communities. Excessive drainage of our energy and material resources can be considerably saved and protected when sustainable agriculture is intensively taken up by the farmers and practiced. Maintaining a healthy soil community which can automatically regenerate soil fertility by providing organic manures, increasing fallow periods, avoiding excessive use of chemical fertilizers and pesticides. The use of alternative food sources which may reduce overdependence to certain crops. Men are exploiting only few species of crop plants as food and cultivate only about 15 species of plants as food crops to feed 90 per cent of the worlds population. There are thousands of species of plants with useful and edible parts which can serve as a food source for the mankind. This will widen our resource base on food crops and add sustainability to supplies by reducing the dependence on a few species. Leaves of Ilex paraguriensis, which can be a substitute for tea and powdered seeds of Cola nitida instead of coffee. Farmers should practice organic farming so that it will not disturb the ecosystem of the cultivable area and leads to sustainable yields at low costs, both to the farmer and to nature. Chemicals, minerals, pesticides and insecticides are now categorised under non-renewable resource materials. Therefore, in the long-term strategy, these materials will make farming non-sustainable and non-productive. New disease resistant virus free plants and stress resistant plants, are successfully produced. Similarly, transfer of nif (nitrogen fixing) gene to non- leguminous crops will improve higher yield. To conclude Sustainable agriculture is an eco-friendly farming system associated with production of food while maintaining on biophysical resources including soil, water, biota with no adverse impacts on the environment. Sustainable farms try to use wind or solar energy instead of purchased energy and use organic manure and nitrogen fixing legumes as green manures to maintain soil fertility thereby reducing supply from outside farms. Organic farming is defined as production systems which avoids the use of synthetic fertilizers, pesticides, growth regulators and livestock feed 250 additives. How are crops improved through selection, polyploid breeding and mutation breeding? Medicinal plants including microbes India is endowed with a rich wealth of medicinal plants. From earliest times mankind has used hundreds of medicinal plants in an attempt to cure diseases and relieve physical sufferings. Medicinal plants are becoming popular throughout the developed world, as people want to treat illness. It is estimated that around 70,000 plant species, from lichens to tall trees, have been used as medicinal plants.

The word epigenetics was originally coined by Waddington in 1942 as a portmanteau of epigenesis and genetics to describe the process by which the genotypes give rise to phenotypes during development . Nowadays, Waddingtons denition would be considered to apply to the eld of developmental biology in general whereas the meaning of the word epigenetics has narrowed to specically refer to non-genetic factors that inuence gene expression. Many other specic factors as well as general alterations in chromatin structure also correlate with different states of gene activity but are not considered primary epigenetic modications as they are not stable through cell division independent of their initial trigger. However, it also leads some to question the use of the term for systems widely referred to as epigenetic such as histone modication, whose independent heritability through cell division is uncertain. Differences in chromatin structure are seen between genes in active and inactive states and reect underlying epigenetic modications. Other alterations observed include changes in large-scale chromatin conformation and physical interactions between normally distant regions of chromatin. In mammals, it is well established to have a mitotically stable silencing effect on genes when present at CpG dense promoter sequences . However, the large majority of silent genes do not have a methylated CpG island at their promoter, indicating that other means of epigenetic control must exist. The contribution of dynamic/tissue-specic changes in methylation in the control of gene expression remains unclear [12,13]. Primordial germ cells undergo genome-wide demethylation early in development, like other post-zygotic cell types and are largely demethylated until gonadal differentiation. The overall level of methylation is somewhat higher in sperm than eggs and sex-specic differences occur at imprinted loci. It occurs before meiosis in male germ cells and during meiotic prophase arrest I in female germ cells. Following this, somatic embryonic cells show the high level of methylation at sequences other than CpG islands that are seen in maturity. Trophoblast cells undergo de novo methylation but remain relatively less methylated. Many post- translational modications involve histones, often in combination with one another, and exert epigenetic control on gene expression. Foremost amongst these are the methylation and acetylation of lysine residues in the N-terminal tails of histones H3 and H4 (Table 13. H3 lysine 9 and H3 lysine 27), trimethylation of H3K4, and acetylation at H3K9 and H3K14. Repressive modications include dimethylation of H3K4 and trimethylation of H3K9, H3K27. Several models have been proposed to explain the heritability of histone modications through cell division, but none is proven (reviewed in ). While this uncertainty remains, some authors argue that histone modications should not be regarded as true epigenetic modications. The best established of these are the Polycomb and Trithorax group proteins which promote transcriptional repression and activation respectively, and both of which act stably through cell division. The two systems interact closely with one another and with other epigenetic systems and have been implicated in the regulation of genes in early development and stem cell renewal. The Polycomb repressor complex 1, the so-called maintenance complex, recognizes this repressive mark and is crucial in the resultant transcriptional repression. A detailed exposition of these inter- actions is beyond the scope of this chapter. Epigenetics in Human Disease Around 60 genes have been shown to be consistently imprinted in man (Geneimprint data- base 2008; Catalogue of Parent of Origin Effects 2009) [74,75]. Some are imprinted in all cell types examined, while others show tissue-specic imprinting, or are only imprinted at certain stages of development. Imprinted genes are often arranged in clusters, each cluster spanning up to several megabases (Table 13. One theory that perhaps best explains the evolution of imprinting is that of parental genome conict. This theory suggests that there is a conict of evolutionary advantage between the paternal genome with the maternal genome which is as a result of the mother carrying the offspring in utero. The maternal genome must preserve herself and resources for future offspring so limits supplies to the baby, whereas the paternal genome only needs to consider the baby and encourages growth. Proponents of the theory point to the existence of a number of imprinted genes that regulate growth and the tendency for paternally expressed genes to promote growth and for maternally expressed genes to suppress growth [26,27]. This can be technically challenging as human tissues are difcult to obtain, limiting systematic expression analysis of the human genes. Instead, known imprinted loci have often been identied following the observation of features suggestive of imprinting, including: 1. Parent-of-origin-specic effects of mutation, copy number abnormality or chromosomal rearrangement 3. Parent-of-origin-specic epigenetic modications in the region (for example differential methylation) 258 5. Even in this small number of loci, the variety of different mechanisms oper- ating is striking. This differential methylation is associated with main- tenance of differential (i. A single differentially methylated imprinting center often appears to control imprinting of multiple genes in a cluster. A further feature shared by a number of loci is the presence of multiple overlapping, often untranslated, transcripts that may play a regulatory function.
