Genetically modified crops

Genotyping-by-sequencing (GBS) has emerged as a powerful and cost-effective approach for discovering and genotyping single-nucleotide polymorphisms. The GBS technique was largely used in crop species where its low sequence coverage is not a drawback for calling genotypes because inbred lines are almost homozygous.

Nitrogen use efficiency is an important breeding trait that can be modified to improve the sustainability of many crop species used in agriculture. Rapeseed is a major oil crop with low nitrogen use efficiency, making its production highly dependent on nitrogen input.

Brassica crops are cultivated widely for human consumption and animal feed purposes, and oilseed rape/canola (Brassica napus and rapa) is the second most important oilseed worldwide. Because of its natural diversity and genetic complexity, genomics studies on oilseed rape will be a useful resource base to modify the quantity and quality of biomass in various crops, and therefore, should have a positive impact on lignocellulosic biofuel production.

Our society has a great concern about transgenic crops regarding mixing of genetic materials between species whose hybridization is not possible naturally. Different public policies on the development and use of genetically modified organisms (GMOs) are of high concern with defining proper risk management strategies. Researchers are in agreement that this technology „„tampers with nature‟‟ in an unacceptable manner.

Present increasing trend of population is alarming for food shortage. It was estimated that by the year of 2050 the population rate may increase up to 9 billion. Rapid increase of human population together with global climate variability resulted in increased demand of plant based food and energy sources. Conventional breeding is still limited due to genetic restrictions (high heterozygosity and polyploidy), long juvenile periods, selfincompatibility, resources restricted to parental genome and exposed to sexual combination.

Molecular characterization is an essential step of risk/safety assessment of genetically modified (GM) crops. Holistic approaches for molecular characterization using omics platforms can be used to confirm the intended impact of the genetic engineering, but can also reveal the unintended changes at the omics level as a first assessment of potential risks.

Vegetables shares major part of the daily dishes prepared in Indian kitchen and are rich in carbohydrate, vitamins, minerals and other phyto-nutraceuticals. But less do we know that these vegetables are heavily-laden with synthetic chemicals and pesticides. In order to gain higher yield most of the Indian farmers uses synthetic chemicals and pesticides which ultimately induced in the food chain and affects human and environment health.

DNA fingerprinting, estimation of molecular genetic diversity, marker assisted breeding and molecular diagnostic tools are the need of the hour for sugarcane crop improvement. Efficient extraction of genomic DNA (gDNA) free from polysaccharides, polyphenols, RNA and other major contaminants is a key to all these molecular activities. We present herewith, a modified DNA extraction protocol that has been optimized for isolating gDNA from endergonic and hardy sugarcane plant and its phytopathogens and endophytic fungi.

Domestication is the process in which plants are genetically modified over time by humans for traits that are more advantageous or desirable for humans. A set of morphological, biochemical, and physiological traits that distinguishes domesticated plants from their wild progenitor is known as domestication syndrome. Reduction/loss of means of dispersal reduction/loss of dormancy, compact growth habit, earliness, gigantism, photoperiod insensitivity, reduction/loss of toxic substances is the major elements of domestication syndrome.

The following are important factors in the future development of agrotechnologies - the development of the world population, advancements with regard to education, progress in food production systems in various regions of the world together with the critical situation of malnutrition in different countries worldwide. It is necessary to improve the production and productivity of crops. Pre-harvest and postharvest losses are still too high, and the use of agricultural inputs, such as fertilizers, irrigation and energy, have to be reduced as much as possible.

Rice (Oryza sativa L.) is among the most important food crops that provide a staple food for nearly half of the world’s population. Rice crops are prone to various types of stresses, both biotic and abiotic. Biotic stresses include insect pests, fungus, bacteria, viruses, and herbicide toxicity. Among abiotic stresses, drought, cold, and salinity are also well studied in rice.

In North America maize is widely utilised due to the suitability of the climate and advances in Genetically Modified (GM) technology which assures consistency of the crop. In areas where conditions for growing maize are not suitable or irrigation is not possible, other crops containing high levels of starch such barley and wheat offer good substitutes. These crops are not harvested until they reach a late “milky dough” stage of maturation so that the levels of starch are maximised.
