ROLE OF GENETIC ENGINEERING IN HORTICULTURAL CROP IMPROVEMENT – A REVIEW. • All genetic crop improvement methods rely … The following points highlight the six methods of crop improvement. In the last few years there has been rapid progress in the area of plant structural and functional genomics. Natural selection operates to bring about evolution of new races and species through the variability created by natural mutations and amplified by subsequent recombination of genes during sexual reproduction. Genomics has progressed tremendously over the past decade and has played a crucial role towards providing necessary knowledge for crop improvement. Role of Genomics in Crop Improvement: Genomics has several practical applications in crop improvement. All three major types of genomic structural variation (presence–absence, copy-number, and homeologous exchange) are now known to influence phenotypes in crop plants, with examples of flowering time, frost tolerance, and adaptive and agronomic traits. 2009). 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. Proc Natl Acad Sci USA 89(20):9865–9869, Hood L, Heath JR, Phelps ME, Lin B (2004) Systems biology and new technologies enable predictive and preventative medicine. Many of our major crop species are polyploids, containing more than one genome or set of chromosomes. Govind Ballabh University of Agriculture and Technology Abstract- Bioinformatics plays a significant role in the development of the agricultural sector, agro-based industries, agricultural by-products utilization and better management of the environment. © 2020 Springer Nature Switzerland AG. 2008b, Taji et al. The methods are: 1. Crop improvement refers to the genetic alteration of plants to satisfy human needs.

Science 306:640–643, Hooykaas PJJ, Schilperoort RA (1985) The Ti plasmid of Agrobacterium tumefaciens: a natural genetic engineer. 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 role of genomic structural variation in the genetic improvement of polyploid crops. CONTENTS • Meaning of Genomics • Types of Genomics • Classification of Genomics • Genome sequencing • Genes to be … 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. enhance crop tolerance to abiotic stress (SDR/iSC:IAR/02/10), elaborating on the role of molecular biology and abiotic stress genomics in genetic enhancement and crop improvement. • Improvement of the nutritional qualities in crop plants: The carotene gene has been transferred from daphoddils to rice grains (Golden Rice) for increasing Beta-carotene content in grains and for solving the blindness in childerns. Role of Genomics in Crop Improvement: Genomics has several practical applications in crop improvement. Improving crop productivity requires taking full advantage of genetic variation within the gene pool. 2007, Peleg et al. 2008). The usefulness of mutation breeding in crop improvement was demonstrated first in Sweden which embarked upon practical plant breeding of agricultural plants by means of X-rays and ultra violet induced mutations (Gustafsson, 1947).

The nearly complete human genome sequence is the cornerstone of genome-based biology and provides the richest intellectual resource in the history of biology. Although it is clear that genomics research has great potential to revolutionize the discipline of plant breeding, high costs invested in/associated with genomics research currently limit the implementation of genomics-assisted crop improvement, especially for inbreeding and/or minor crops. Rapid exchange of knowledge and the establishment of critical collaborations are vital to remaining on the cutting edge of this field. Defining the role of each gene in the complex cellular machine and network is a formidable task. Recent advance- ments in plant genomics are certainly of help in crop improvement efforts (Varshney et al. Authors .
