  • Forward and Reverse Genetics Approaches in Functional Genomics    By: Waghmare Sandesh Tulshiram

    Functional genomics is characterized by high-throughput or large-scale experimental methodologies combined with statistical or computational analysis of the results. Functional genomics as a means of assessing phenotype differs from more classical approaches primarily with respect to the scale and automation of biological investigations. Forward genetics starts with identification of interesting mutant phenotype. Forward genetics seeks to find the genetic basis of a phenotype or trait. Automated DNA sequencing generates large volumes of genomic sequence data relatively rapidly. Reverse genetics starts with a known gene and alters its function by transgenic technology. Reverse genetics however, due to the advent of advances in sequencing is employed to seek out what sequences underlies the phenotype >> Category: Genetics

  • Molecular Markers in Crop Improvement    By: Dr. Sundeep Kumar

    Molecular markers have found large scale applications in crop improvement programs, because of several advantages over morphological and biochemical markers. Molecular markers are environmentally neutral, highly abundant, and independent of tissue and stage of the plants. Traditionally, breeders have relied on visible traits to select improved varieties however; MAS rely on identifying marker DNA sequences that are inherited alongside a desired trait during the first few generations. Molecular markers are also considered as useful tools for pyramiding of different resistance genes and developing multi-line cultivars targeting for durable resistance to the disease. >> Category: Genetics
  • Seed Dormancy in Groundnut [PDF]    By: Chetan Desai

    The inability of certain seeds to germinate readily even when they are provided with all conditions required for germination is known as seed dormancy. A dormant seed is not a 'failure'. It may be due to conditions associated either with the seeds itself or with existing environmental factors such as temperature and moisture. In general, in groundnut, bunch types are non-dormant while spreading and semi spreading types are having a varied period of dormancy. The seeds show marked dormancy, ranging from 30 to 360 days. >> Category: Genetics

  • Gene Bookmarking - To keep the molecular pages open    By: Rama Prashat G

    The genetic material is transferred to the daughter cells and in subsequent generations through mitosis. Cells must have a way to remember the genes which are active before cell division and must follow the same pattern through mitosis into daughter cells. To remember which genes were active before the onset of mitosis, the active genes are in some way 'marked' and the daughter cells reassemble the transcriptional machinery on the promoters of those active genes. 'Gene bookmarking' is one of the mechanisms by which the phenotype is remembered through cell lineages. >> Category: Genetics
