Transformation:
Transformation means direct uptake, incorporation and expression of foreign genetic material from its surrounding (S.Cohen et al.,1980)
Transformation in Plants:
In plants the processes of creating a transgenic plants by introducing new genes into an organism is known as transformation.
(Encyclopedia of life by Wiley Black Well)
Why we need transformation?
The main three challenges for mankind in today’s century are food, energy and the environment.
Plant life is important factors in all three of these issues. Photosynthetic plants are the major source of are energy and food. Researches on plants have done to provide solutions to these challenges.
The basic biology of plants is similar to us. However, their forms and lifestyle are fundamentally different. Plants can survive up to 5000 years; they can obtain nutrition from the air and soil and withstand environmental stress and attacks from pests (David w.Ehrharth, 2012)
But with the increase in pollution, overpopulation etc. plant lives are in danger and in result, in fact, humans are in danger. So, for the survival of both, scientists worked very hard and discover various techniques to transform the genetic material of plants so that they can protect themselves, increase their yield.
Purpose of transformation:
The main purpose of transformation in plants is:
• Production of disease free plants
• Improve the quality of plants
• Improving quantity i.e. productivity
• Environment friendly plants
• Drought and salt resistance in plants
• value-added traits
• For the experimental use
Requirements for transformation:
The procedure of transformation should be:
• Easy
• Inexpensive
• Dangerous procedures and harmful substances should be avoided
• Technical simplicity shou...

...of its export to the cytoplasm by the host RNA export machinery viral vectors that not only replicated well in infected cells but also were delivered by the T-DNA of Agrobacterium more effectively. Genetically modified plants are already a viable part of modern agriculture.
The development of new technologies for the stable and transient expression of recombinant proteins in plants could potentially provide more versatile biotechnological tools for the scientific and commercial communities (trends in plant sciences Vol xx no xx Month 2005)
(THE END)
When thinking of birds, visualizing them building their nests in cacti certainly isn't the first thing that comes to mind. In the book, The Bean Trees by Barbara Kingsolver, metaphorically everyone is constantly building their nests in cacti, and evolving from their experiences. From living in attics to taking trips across the country with no destination, characters in this book don't live what society considers the “conventional American lifestyle.” Growing and thriving in unexpected and unusual places and ways is nothing but average throughout the book. Taylor, despite unorthodox living arrangements or lifestyle, shows how living things are able to find methods of growing and changing. From great change in location to change within oneself, idiosyncratic development shapes the voyage this book takes.
Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...
Whilst some refer to transgenic organisms as, “Frankenfoods”, the proponents see this as the second Agricultural Revolution. Biochemists cite the classical example of a transgenic banana which could produce vaccines as a means to continue their research. Undoubtedly if such a banana did exist it could potentially provide millions if not billions of people access to vaccinations. The chair of the Food and Agribusiness Institute at Santa Clara University states, “Bioengineering is just a more refined process [of selective breeding], which will probably result in more productive animals and plants at a lower cost than traditional breeding methods.” This “more refined process” has served to create corn, which is resistant to pests such as corn borers; tomatoes, which can resist cold temperatures and have increased traveling durability; and arguably the most important, cattle which is resistant to mad cow disease. Aside from the clearly visible genetic advantages provided by transgenic organisms, proponents further cite the colossal economic impact of GMOs. PG Economics issued a report which reveals the net economic benefit at the farm level in 2011 was $19.8 billion, and over a 16 year period from 1996 to 2011 the global farm income gain was $98.2 billion. This 16 year period coincides with the adoption of transgenic cropping systems.
A GMO is a plant or animal that has been genetically engineered with DNA from bacteria, viruses, or other plants and animals. Most of the combinations which are used could not possibly occur in nature on its own. The intention of the process is to create a new beneficial trait such as creating its own pesticide or make it immune to herbicides. This would allow the crop such as Bt co...
With an ever increasing world population, massive third world hunger, and with an estimation that a child dies for every two seconds world-wide from starvation; this does not even take into account the number of people who are mal and undernourished, there is a great promise in the use of this technology to benefit not only the farmers, but also societies worldwide. We have been able to genetically modify plants so that they may be more resistant to insects, so that there is less pesticidal toxins sprayed. We have designed plants that require less water, less soil nutrients, preserving precious recourses. We have designed plants with higher yield, shorter seasons, plants that need less land to grow; we are said to be living in a time where we have the healthiest, most well-tested plants in the history of this
Pamela Ronald, a plant geneticist, presented a Ted Talk “The case for engineering our food”, Ronald points out that engineered genetics for our plants is not harmful, yet better for our environment and health. “Now, genetic modification is not new; virtually everything we eat has been genetically modified in some manner”(Ronald).
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
What are the most critical needs and challenges will face over the next three years?
The Versatility and Adaptation of Plants for Survival In many ways, plants are far more versatile and successful for life on earth than animals and have been here for far longer. They were the first to colonise this planet, and without them we would not exist, for we are totally dependent on them. Even today with all our technology they continue to amaze us with their ability to inhabit places we humans could not survive, from the frozen Antarctic to the intensity of a volcanic spring, plants utilise their environments to their own advantage and evolve to survive the harshest of landscapes. A plant needs four basic things to survive, water, warmth, light and minerals and any place that can provide even a little of these essential needs, will be colonised by plants.
From oxygen to food to shelter to energy to shade, plants provide us with virtually everything we need to survive and to thrive. Genetics and Plant Biology (GPB) majors study the distribution and diversity of plant life from the sub-molecular to the organismal level. There is momentous work to be done for those who want to unravel the mystery of genes, bring expertise to medical school, educate future biologists, or develop methods to feed the world! With biogenetics, you can change the plant different from which it was originated for to whatever benefits you. But is change better for you? probably not. We as humans need to leave the plants just how God created them and be good caregivers to the plants instead of changing them for our benefits. God created the plants
The plants that we know today as terrestrial organisms were not always on land. The land plants of today can be linked back to aquatic organisms that existed millions of years ago. In fact, early fossil evidence shows that the earliest land plants could have arisen some 450 million years ago (Weng & Chappie 2010). Plants that used to reside strictly in water were able to adapt in ways that allowed them to move onto land. It is speculated the need for plants to move onto land was created by water drying up, causing plants to have less room and pushing them to move onto land. Although the exact cause of plant’s need to move to a terrestrial environment is unclear, it is known that plants had to undergo several adaptations to be able to live on land. These adaptations include: lignin, cellulose, suberin, and changes to plant’s surface, including the formation of a waxy cuticle.
In order to build a successful civilization, one will need accessible nutritious plants. For example,
Tissue culture allows for the clonal propagation of plant (production of multiple copies of the same genotype).
Biotechnology helps in protecting the environment,It provides crops with protection from viruses and insects by reducing the number of pesticid...
One of the most complex issues in the world today concerns human population. The number of people living off the earth’s resources and stressing its ecosystem has doubled in just forty years. In 1960 there were 3 billion of us; today there are 6 billion. We have no idea what maximum number of people the earth will support. Therefore, the very first question that comes into people’s mind is that are there enough food for all of us in the future? There is no answer for that. Food shortage has become a serious problem among many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water shortages are just merely two examples out of them all.
