Genetically modified (GM) cotton, like GM corn, has been developed to improve agricultural productivity, reduce environmental impact, and enhance the quality of cotton. Below is an in-depth exploration of GM cotton, covering its development, specific traits, practical implications, and related concerns. Development of GM Cotton GM cotton was first developed in the 1990s to address key challenges in cotton production, including pest infestations and herbicide use. The primary goals were to increase yield, reduce pesticide use, and lower the environmental impact of cotton farming. Genetic Engineering Techniques : Agrobacterium tumefaciens-Mediated Transformation : A common method where the Agrobacterium bacterium is used to introduce new genes into the cotton plant’s genome. Particle Bombardment (Gene Gun) : A physical method where DNA-coated particles are shot into the plant cells to deliver the new genes. Target Genes : Insect Resistance Genes : Genes from the bacterium Bacillus th...

Genetically modified corn (GM corn) has been engineered for various traits to improve agricultural efficiency, environmental sustainability, and crop quality. Here, we will delve into the specific traits of GM corn, the techniques used in its development, and the practical implications across different domains. Specific Traits of GM Corn Insect Resistance Bt Corn : Contains genes from the bacterium Bacillus thuringiensis (Bt) that produce proteins toxic to specific insect pests, such as the European corn borer and corn rootworm. This reduces the need for chemical insecticides and minimizes crop losses due to pest damage. Herbicide Tolerance Glyphosate Tolerance : Engineered to tolerate glyphosate, the active ingredient in the herbicide Roundup. Farmers can apply glyphosate to control weeds without harming the corn plants. Glufosinate Tolerance : Similar to glyphosate tolerance, but for the herbicide glufosinate. Disease Resistance Viral and Fungal Resistance : Some GM corn vari...

  Here is a list of some of the commercially available genetically modified (GM) corn varieties, categorized by the traits they possess. This list includes popular GM corn products developed by various biotechnology companies: Insect-Resistant Corn (Bt Corn) MON 810 : Monsanto's Bt corn, expressing the Cry1Ab protein from Bacillus thuringiensis . Bt11 : Syngenta's Bt corn, expressing the Cry1Ab protein. TC1507 : Dow AgroSciences' Bt corn, expressing the Cry1F protein. MIR162 : Syngenta's Bt corn, expressing the Vip3Aa20 protein. DAS-59122-7 : Dow AgroSciences' Bt corn, expressing Cry34Ab1 and Cry35Ab1 proteins. Herbicide-Tolerant Corn NK603 : Monsanto's Roundup Ready corn, tolerant to glyphosate.

MON 87427 : Monsanto's glyphosate-tolerant corn. Stacked Traits (Inse...

  Recently, I have attended a refresher session on Mycotoxins & their on-Field diagnosis using LFD. I will be sharing my learnings in a summarized way so that you can also get benefited. Understanding Mycotoxins Mycotoxins are toxic secondary metabolites produced by certain molds and fungi, which can contaminate food and feed products. These toxins pose significant health risks to humans and animals, leading to various diseases and even death in severe cases. Common mycotoxins include aflatoxins, ochratoxins, fumonisins, trichothecenes, and zearalenone, each with unique chemical properties and toxicological effects. Sources and Impact of Mycotoxins Mycotoxins can contaminate crops both pre-harvest and post-harvest. Factors such as weather conditions, poor storage practices, and insufficient processing can exacerbate contamination levels. Contaminated food products, when consumed, can lead to acute poisoning, chronic health issues such as cancer, liver damage, immune suppre...
