    Plant breeding, application of genetic principles to produce plants that are more useful to humans. This is accomplished by selecting plants found to be economically or aesthetically desirable, first by controlling the mating of selected individuals, and then by selecting certain individuals among the progeny. Such processes, repeated over many generations, can change the hereditary makeup and value of a plant population far beyond the natural limits of previously existing populations. This article emphasizes the application of genetic principles to the improvement of plants; the biological factors underlying plant breeding are dealt with in the article heredity. >> Category: Agriculture
  • Synthetic Variety Development    By: SUNIL KUMAR, S.V.

    A synthetic variety is developed by intercrossing a number of genotypes of known superior combining ability--i.e., genotypes that are known to give superior hybrid performance when crossed in all combinations. (By contrast, a variety developed by mass selection is made up of genotypes bulked together without having undergone preliminary testing to determine their performance in hybrid combination.) Synthetic varieties are known for their hybrid vigour and for their ability to produce usable seed for succeeding seasons. Because of these advantages, synthetic varieties have become increasingly favoured in the growing of many species, such as the forage crops, in which expense prohibits the development or use of hybrid varieties. >> Category: Agriculture
  • SDS-PAGE and its Applications in Crop Improvement    By: SUNIL KUMAR, S.V.

In most proteins, the binding of SDS to the polypeptide chain imparts an even distribution of charge per unit mass, thereby resulting in a fractionation by approximate size during electrophoresis. >> Category: Agriculture
  • Proteome - The Useful in Understanding Plant Insight    By: SUNIL KUMAR, S.V.

    The proteome is the entire set of proteins expressed by a genome, cell, tissue or organism. More specifically, it is the set of expressed proteins in a given type of cells or an organism at a given time under defined conditions. The term is a portmanteau of proteins and genome. The term has been applied to several different types of biological systems. A cellular proteome is the collection of proteins found in a particular cell type under a particular set of environmental conditions such as exposure to hormone stimulation. It can also be useful to consider an organism's complete proteome, which can be conceptualized as the complete set of proteins from all of the various cellular proteomes. This is very roughly the protein equivalent of the genome. >> Category: Agriculture
  • Artificially Induced Mutations    By: SUNIL KUMAR, S.V.

    Breeding has been practiced since the early human civilization and selection was the first method of breeding, adding the criteria of suitability for man's use (e.g. larger seed, better taste, easier harvestability) to those of natural adaptation, fitness and offspring. It has been said, that the ultimate source of all heritable variation to select from are mutations. But such a statement leaves open, where the genes to start with and the genetic code came from. Recombination of genes can provide additional genetic variation, if differences exist not only between various genes, but also in form of alleles of particular genes of prospective recombinants. Such alleles derive from mutations. Using mutants in cross breeding requires no in depth knowledge about mutations, because the mutated trait is the object of desire. But when the mutant trait is not inherited as expected, the breeder may begin to think about the actual mutational event, that led to the mutant phenotype. >> Category: Agriculture
  • Transcriptome - Aventure Into Crop Improvement    By: SUNIL KUMAR, S.V.

    Background selection refers to selection applied to regions of the genome that are not known to be associated with desired traits. This type of selection is usually referred to in the context of trait introgression. Trait introgression, the process of integrating a trait from one species into another, is a common strategy used for crop improvement. >> Category: Agriculture
  • Gene Pyramiding in Crop Improvement    By: SUNIL KUMAR, S.V.

    The development of molecular genetics and associated technology like MAS has led to the emergence of a new field in plant breeding-Gene pyramiding. Pyramiding entails stacking multiple genes leading to the simultaneous expression of more than one gene in a variety to develop durable resistance expression. Gene pyramiding is gaining considerable importance as it would improve the efficiency of plant breeding leading to the development of genetic stocks and precise development of broad spectrum resistance capabilities. The success of gene pyramiding depends upon several critical factors, including the number of genes to be transferred, the distance between the target genes and flanking markers, the number of genotype selected in each breeding generation, the nature of germplasm etc. Innovative tools such as DNA chips, micro arrays, SNPs are making rapid strides, aiming towards assessing the gene functions through genome wide experimental approaches. The power and efficiency of genotyping are expected to improve in the coming decades. >> Category: Agriculture

    Biotechnology in agriculture has two categories: (1)'improvements' to existing livestock and crops, and (2) development of entirely new uses for both animals and plants (Biopharming ) So called 'improvements', include 'input traits' such as crops with extra resistance to insect attack and improved weed control. These 'GM' or 'GMO' crops are modified food crops made more commercially viable, e.g. 'Roundup ready' soya, 'Starlite' corn, or 'Frost-tolerant' tomatoes. Consumers are worried about the safety of their food. Unfortunately we already have cases of compliance failures... By SUNIL KUMAR, S.V. and ANIL KUMAR, S.V. >> Category: Agriculture

  • In Situ Hybridization (ISH)    By: SUNIL KUMAR, S.V.

    In Situ Hybridization (ISH) is a technique that allows for precise localization of a specific segment of nucleic acid within a histologic section. The underlying basis of ISH is that nucleic acids, if preserved adequately within a histologic specimen, can be detected through the application of a complementary strand of nucleic acid to which a reporter molecule is attached. Visualization of the reporter molecule allows localizing DNA or RNA sequences in a heterogeneous cell populations including tissue samples and environmental samples. Riboprobes also allow to localize and assess degree of gene expression. The technique is particularly useful in neuroscience. >> Category: Agriculture
  • Polymerase Chain Reaction (PCR)- Its Applications    By: SUNIL KUMAR, S.V.

    PCR (Polymerase Chain Reaction) is a revolutionary method developed by Kary Mullis in the 1980s. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. Because DNA polymerase can add a nucleotide only onto a preexisting 3'-OH group, it needs a primer to which it can add the first nucleotide. This requirement makes it possi. >> Category: Agriculture
  • Electrophoresis - Its Venture Into Agricultural Biology    By: SUNIL KUMAR, S.V.

    Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. This electrokinetic phenomenon was observed for the first time in 1807 by Reuss (Moscow State University), who noticed that the application of a constant electric field caused clay particles dispersed in water to migrate. It is ultimately caused by the presence of a charged interface between the particle surface and the surrounding fluid. Electrophoresis of positively charged particles (cations) is called cataphoresis, while electrophoresis of negatively charged particles (anions) is called anaphoresis. >> Category: Agriculture
