Plant biotechnology

Biotechnology is defined as biology-based technology using organisms or their parts to make or modify products or to improve characteristics of plants, animals, and microorganisms for the demands of human beings. This article reviews the current research, challenges, and perspectives of biotechnology as an integration of both life sciences and applied sciences.

The aim of this project was to select highly sensitive and specific aptamer capable of detecting Fusarium graminearum (Fg) and F. pseudograminearum (Fp) species. The aptamer-based testing allows early detection of fungal infection in the field. Fungi are known to change their activity and may often undergo genetic changes. The classic "gene for gene" theory explains the relationship between host plant cultivars and fungal pathogenic races.

The thesis investigates the growth promoting effects of plant growth promoting bacteria (PGPB) in chickpea and wheat. Three main topics covered are: 1) Isolating local Plant Growth Promoting Bacteria; 2) Screening and characterization of isolates; 3) Assessment and identification of the selected strains.

the results have shown that among twelve isolated bacterial strains, three strains were screened based on their enzymatic potential, and were later identified by 16S rRNA gene sequencing, i.e. showing that the strains belong to the genus Pseudomonas aeruginosa, and Bacillus wiedmannii with a similarity percentage of 99.33% and 100%, respectively, with their corresponding type of strains.

The present research was carried out to determine the anatomical features of leaves of Alangium salviifolium and their endophytic fungal association. Alangium salviifolium is an important medicinal plant with various activities reported. It is suggested that the medicinal property of the plant is either because of their endophytes or the endophytes inherit the medicinal properties from their host plant. Hence the detailed study of plant- microbe interaction is important.

Bacteria-based biotechnological processes are applied to minimize the content of CNG in food products. For the usability and identification of the added value of plant food resources, it is important to know the functions and importance of antinutritional components of metabolism with a consequent impact on nutrition and health. In the review we provided a comprehensive view of the importance and potential of CNG in plants with a focus on food resources, where the model object was presented by linseed.

Pre-requisite for any plant biotechnological approach is development of an efficient plant regeneration system in that crop. In this regard the in vitro regeneration was achieved by using cotyledon explants from aseptically raised seedlings of popular Capsicum F1 hybrids Bharat and Indra. Seeds of both hybrids were exposed to different treatments for proper germination, were decontaminated and sown in vitro on half-strength MS medium.

Coffee plant is one of the most important industrial crops, and the two popular cultivars, Coffea arabica and Coffea canephora, contribute to the production of almost all coffee beans around the world. Traditional breeding could be used to develop new coffee cultivars with a higher productivity under these harsh conditions, and a biotechnological approach can also be used to improve coffee plants in a relatively short period of time.

An applied field of biology that involves the use of living organisms and bioprocesses in engineering, technology, medicine and other fields requiring bioproducts. (http://en.wikipedia.org/wiki/Biotechnology) It is the products and exploitation from other fundamental sciences.Traditional Biotechnology Traditional biotechnology refers to a number of ancient ways of using living organisms to make new products or modify existing ones. In its broadest definition, traditional biotechnology can be traced back to human's transition from hunter-gatherer to farmer.

Glofish is the first transgenic animal approved to be consumed by human in the USA  The insertion of different constructs of GFP into the fish genomes to give different green colors.The idea for recombinant DNA was first proposed by Peter Lobban, a graduate student of Prof. Dale Kaiser in the Biochemistry Department at Stanford University Medical School. The first publications describing the successful production and intracellular replication of recombinant DNA appeared in 1972 and 1973.

Polymerase Chain Reaction is widely held as one of the most important inventions of the 20th century in molecular biology. Small amounts of the genetic material can now be amplified to be able to a identify, manipulate DNA, detect infectious organisms, including the viruses that cause AIDS, hepatitis, tuberculosis, detect genetic variations, including mutations, in human genes and numerous other tasks.

Leaf explants of Echinacea purpurea L. taken from aseptically germinated seedlings were inoculated with A. tumefaciens strains EHA105, carrying a binary vector conferring herbicide resistant bar gene and fungal resistant chitinase gene. Glufosinate ammonium‐resistant shoots were regenerated on a medium containing BAP and NAA at a concentration of 4.88 and 0.053 μM, respectively. A subsequent transfer of shoots to medium containing BAP was necessary for stem elongation and leaf development.

important regulators of biological processes in animals and plants. MiRNAs regulate gene expression at the posttranscriptional level by binding to mRNAs and either inhibit translation or modify the stability of the mRNA. Due to the important biological role of miRNAs it is of great interest to study their expression level in the cells. Furthermore, miRNAs have been associated with cancer and other diseases [1] and miRNA expression can help in the diagnosis and prognostic of human disease [2,3].
