Functional Genomic Approaches in Plant Research. DNA sequencing technology is undergoing a revolution with the commercialization of second generation technologies capable of sequencing thousands of millions of nucleotide bases in each run. Advances in Plant Genotyping: Where the Future Will Take Us. In these cases, the use of molecular markers to select for the underlying genetic determinants of the trait increases the efficiency of crop breeding. These markers can be used to develop haplotypes for genes or regions of interest, and complete genome mapping is now becoming a reality. Second generation sequencing describes platforms that produce large amounts (usually millions) of short DNA sequence reads of length typically between 25 and 400 bp. tauschii. Even cereal genomes such as wheat and barley which were once considered intractable are coming under the spotlight of the new sequencing technologies and an array of new projects and approaches are being established. J Biol Chem. The draft consensus sequence for the grape genome identified 1.7 million SNP which were mapped to chromosomes (Velasco et al., 2007). Transgenic trait deployment using designed nucleases. Journal of Crop Science and Biotechnology. : 2015315514 Discipline : I MS Biotechnology 2. Agricultural Development and Food Security in Developing Nations. 2014 Jun 10;12(6):e1001883. High‐throughput genotyping for species identification and diversity assessment in germplasm collections. Molecular markers have revolutionized genome mapping over the last two decades, and the high density of markers that can now be generated from second generation sequence data offers the potential for generating very high density genetic maps.

With the development of molecular techniques, MAS is now used to enhance traditional breeding programs to improve crops, and modern plant breeding is dependent on molecular markers for the rapid and precise analysis of germplasm and for trait mapping (Koebner and Summers, 2002). 2010; 8(1):2-9 (ISSN: 1467-7652) Edwards D; Batley J. DNA sequencing technology is undergoing a revolution with the commercialization of second generation technologies capable of sequencing thousands of millions of nucleotide bases in each run. 2020 Sep 18;11:585515. doi: 10.3389/fpls.2020.585515. Pacific biosciences have developed a single‐molecule real‐time sequencing system that promises to produce several Gbp of relatively long reads (>1 kbp) (Eid et al., 2009). Biotechnological Perspectives of Omics and Genetic Engineering Methods in Alfalfa. Sugarcane genome sequencing by methylation filtration provides tools for genomic research in the genus accharum. germplasm from East Africa and IITA inbred lines. Association mapping is a further statistical method to identify genetic loci associated with phenotypic trait variation. Environmental and Agricultural Informatics. Roche 454 sequencing, using a combination of whole genome shotgun and bacterial artificial chromosomes (BAC) sequencing, has been used to recently complete the 1.7 Gbp oil palm genome (http://tinyurl.com/palmgenome). PLoS Biol. . Roche 454 sequencing has been used to survey the genome of Miscanthus (Swaminathan et al., 2009), while Sanger, Illumina Solexa and Roche 454 sequencing are being used to interrogate the genome of banana (Hribova et al., 2009). However, the challenge remains to convert this mass of data into knowledge that can be applied in crop breeding programs. Genetic and Molecular Regulation of Seed Storage Proteins (SSPs) to Improve Protein Nutritional Value of Oilseed Rape (Brassica napus L.) Seeds.
