role of genomics in crop improvement

Through genomics, we have been able to identify and characterize the genes involved in salinity stress response, map out signaling pathways and ultimately utilize this information for improving the salinity tolerance of existing crops. Considerable work was already underway in the CGIAR aimed at stress tolerant crop improvement: the Centres, along with NARS and ARIs, were seeking an understanding of the genetic control of tolerance to the key stresses in their regions for their mandate crops, and applying the knowledge to breeding programmes. Besides the growing population rate, extreme weather, reduced agricultural land availability, increasing biotic and abiotic stresses are significant constraints for farming … The use of crop wild relatives (CWR) genes to improve crop performance is well established with important examples dating back more than 60 years. The participants were exposed to DArT/SSR markers, linkage and QTL mapping, association mapping and its applications in crop improvement, introduction and application of genomic selection and its applications, NGS technologies, bioinformatics tools in crop improvement etc. Chaudhary J(1), Deshmukh R(2), Sonah H(3).

In: Principles of plant-microbe interactions. Genetic crop improvement can contribute towards solving this complex problem. Crop improvement refers to the genetic alteration of plants to satisfy human needs. This review articulates the role of histone modifications and DNA methylation in modulating biotic and abiotic stresses, as well as crop improvement. Accessing genome-wide sequence variation by re-sequencing significantly improves the availability of information that can be used to develop markers, thereby enhancing the genetic mapping of agronomic traits. Moreover, the availability of whole-genome sequence information for large number of crops has enabled target-specific genome editing … In various crop species such as wheat, barley and sorghum, DArT markers have been used together with conventional molecular markers to construct denser genetic maps and/or to perform association studies (Crossa et al. 2008).

Crop domestication satisfies the human need for food and nutrition. Although the two main types of genomic structural variation commonly identified are presence–absence variation and copy-number variation, we propose that homeologous exchanges constitute a third major form of genomic structural variation in polyploids.

From these it is possible to understand the reasons for the improvements in yield. A major challenge in polyploid crop improvement is in discriminating between homeologous alleles; that is, alleles present at homeologous loci (in different genomic locations), rather than homologous loci (alleles present at the same locus on two homologous chromosomes). The present bulletin “Molecular markers in crop improvement” has been designed to provide a basic understanding with regards to use of molecular markers in crop improvement. • Novel genetic techniques have been developed in recent years and are advancing rapidly.
