Effect of Deleterious Rhizosphere Microorganisms in Presence of HCN
By:
Shruti agrawal
The saprophytic microflora of the rhizosphere includes both deleterious and beneficial elements have the potential to influence the plant growth and yield, significantly. Their deleterious activities include alterations of the supply of water, ions and plant growth substances by changing root functions or limiting their growth. The beneficial bacteria affect plant growth positively by promoting the availability and uptake of mineral nutrients, provision of plant-growth substances as well as suppression of deleterious rhizosphere microorganisms. Deleterious rhizosphere microorganisms (DRMO) are the minor pathogenic rhizosphere microorganisms that affect plants by their metabolites without parasitizing plant tissue. These include deleterious rhizobacteria and rhizofungi.

Orchids : The Defined Beauty of Nature on Earth
By:
Shruti agrawal
Theophrastus, the father of botany (370 -285 BC) named 'ORCHIDS' on the basis of the resemblance of paired underground tubers to masculine anatomy (the testes). They shows fascination for their beautiful flowers. They represent to the family Orchidaceae, the most highly evolved family among monocotyledons with 600 to 800 genera and 25,000-35,000 species in the world. They are peculiar and are highly valued in the international market.

Functional Foods
By:
S gaind
Functional foods may be whole, fortified, enriched, or enhanced foods. They are defined as any food or food ingredients that may provide a health benefit beyond the traditional nutrients present in it. Traditional nutrients refer to vitamins and minerals. Functional foods don't differ from conventional food, in appearance and are consumed as part of usual diet

Isolation of Plasmid DNA From E.Coli Part-1
By:
amar nagesh
Step by step procedure for the isolation of plasmid DNA from Escherichia coli. A plasmid is a small circular piece of DNA (about 2,000 to 10,000 base pairs) that contains important genetic information for the growth of bacteria. In nature, this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic.A plasmid is a small circular piece of DNA (about 2,000 to 10,000 base pairs) that contains important genetic information for the growth of bacteria.

Hemochromatosis and its Genetic Inheritance
By:
Shalini Balan
What is Hemochromatosis and how it is caused? Hemochromatosis is genetic disorder that is inherited from both the parents .In this condition the amount of iron in the body is usually higher than the required. The body absorbs and stores more amount of iron, which in turn gets stored in the organs like pancreas, liver, and skin. If they are not properly treated and regularly monitored iron abnormalities may lead to damage of the organs.

Risk Modeling
By:
Shivika Bhatnagar
The scientific technique used to detect the possible risks of GEOs is called risk modeling. It includes both laboratory and field techniques. The identification of possible risks of GEOs is the first step of risk modeling. We cannot know the risk suitable experiments are carried out under the laboratory conditions.

Risk Assessment For GEOs
By:
Shivika Bhatnagar
Possible Dangers of GEO: Environmentalists and medical professionals argue the deliberate release of GEOs in the nature. They say that, though beneficial today, GEOs will be a source of threat to the existence of man and animals on the earth. Hence scientists have decided to assess the possible risks, the GEO will produce before releasing the GEO. The process of assessing possible risks of GEOs is called risk assessment or risk evaluation.

Transgenic Virus Resistant Plants.
By:
Shivika Bhatnagar
Viral infection causes substantial plants and crop loss every year. It reduces the rate of photosynthesis and growth vigor. The net result is the low yield and income. Viral infection does not take place in plants already infected with certain viruses. The principle is called cross protection. By using this principle plant genetic engineers have been developing transgenic virus resistant plants.

Genetics of Nitrogen Fixing Microorganisms
By:
Shivika Bhatnagar
In Rhizobium species, nodulation genes together with other symbiotic genes, are located on large-plasmids (Sym plasmids). Sym plasmids vary from 50 to over 600 kb in R. leguminosarum bv. Trofoli to 1200 to 1500 kb in R. meliloti. Nodulation genes, nod and nol genes, are classified as regulatory, common and host specific. Regulation of nod genes is controlled by the nod gene, of which all rhizobia tested so far contain one or more copies. In conjunction with plant flavonoids or other phenolic compounds, nod proteins act as transcriptional activators of inducible nod genes.

Mycoherbicides: Weeds-killing Fungi
By:
Shivika Bhatnagar
Many fungi of native origin are pathogenic to specific species of weeds. Such fungi are used to kill the weeds selectively and eliminate them from the area. These weeds-killing fungi are called mycoherbicides. eg. [i]Phytopthora palmivora [/i]is used to control the weed [i]Morrenia odorata.[/i]

Cryopreservation - Storing a Living Organism at Ultra-Low-Temperature
By:
Shivika Bhatnagar
what is Cryopreservation? The in vitro preservation of plant materials at -196 C for a long time using liquid nitrogen is called cryopreservation. Cell suspensions, hybrid protoplasts, pollen grains, seeds and meristem of desired plant races are stored in this medium. Cryoprotective agents are chemicals which protect plant materials from damaging effects of cold storage.

Azolla: A Green Manure
By:
Shivika Bhatnagar

Biosyntheis of Cytokinin
By:
Shivika Bhatnagar
Cytokinins are degradation products of DNA. They are made up of adenine nucleus and a furfural ring. This basic structure is known as 6- furfuryl aminopurine. Cytokinins stimulate cell division and enlargement of cells. The deficiency of cytokinins results in stunted growth in plants.

Classification and Enzymes - Uses and Production of Enzymes
By:
Shivika Bhatnagar
Enzymes are proteins which catalyse the biochemical reactions in living cells. Chemically they are globular proteins secreted by cells to regulate their metabolic activities. The enzymatic reactions are very specific, i.e. a particular enzyme catalyses only a particular biochemical reaction, but not others.

Mushroom Ingredients and Advantages - The Edible Fungi
By:
Shivika Bhatnagar
Mushrooms are the fast growing basidiomycetous fungi which produce fleshy fruit bodies. However, in general the word 'mushrooms' denotes fruit bodies of such fungi. The mushrooms may be button- like or fan- like or umbrella shaped. They are rich in proteins, vitamins and minerals. So they are consumed as energy rich food.
