plant genome sequencing applications for crop improvement

Markers are used in agricultural breeding programs to incorporate genetically characterized traits in place of field trials or glass house screens. The identification of genes and molecular markers underlying these agronomic traits will help accelerate the breeding process and lead to improved varieties with improved yield and quality, tolerance to unfavourable environmental conditions and resistance to disease. Molecular Approaches for Harvesting Natural Diversity for Crop Improvement. PLoS Biol. The Illumina system is used for genome re‐sequencing, transcriptome profiling (RNA Seq) and Chromatin ImmunoPrecipitation sequencing (ChIP Seq), and the relatively low error rate of this system supports de novo sequencing applications. Reference genome sequences for several crop species are now becoming available and this information permits both the rapid identification of candidate genes through bioinformatics analysis, and single nucleotide polymorphism (SNP) discovery through comparison of the reference with sequence data from different cultivars.

Association mapping shares much in common with quantitative trait loci (QTL) mapping. As with most molecular markers, the factor limiting the implementation of SNP is the initial cost of their development (Duran et al., 2009b). This data can also be applied for SNP and simple sequence repeats (SSR) molecular marker discovery, though without a reference genome sequence, genetic mapping of these markers is required to determine their genomic location. Rediscovery of Genetic and Genomic Resources for Future Food Security. Working off-campus? Gene Pool Diversity and Crop Improvement. MAS allows the breeder to achieve early selection of a trait in a breeding program, and it is particularly useful when the trait is under complex genetic control, or when phenotypic trials are unreliable or expensive. germplasm from East Africa and IITA inbred lines. And, to date, it is probably the best sequenced and assembled plant genome in terms of completeness. Next Generation Sequencing in Crop Improvement Dr.S.Uma, Principal Scientist & Head, Crop Improvement Division, NRCB, Trichy . The large cereal genomes in particular remain elusive, but advances in technology are starting to make de novo sequencing of these genomes feasible.
