Not logged in Finally, crop improvement has flourished from genetic changes which have produced only small changes in yield and thus increases in crop yield of 5% in a new variety can be sufficient to ensure its widespread adoption. Annotated genome sequences, transcriptomic data, and genetic maps of plant species are all potentially useful resources for improving crop breeding programs. Role of Genomics in Crop Improvement: Genomics has several practical applications in 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. The help rendered by Shri … Role of mutation breeding in crop improvement. Advances in next-generation sequencing (NGS) technologies coupled with improved genome assembly algorithms have … MASTER SEMINAR ON GENOMICS AND ITS APPLICATION IN CROP IMPROVEMENT DATE-24/03/2018 SPEAKER KHEMLATA THAKUR M.Sc. Why is crop improvement necessary? Because … 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. 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). 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. Induced mutagenesis is one of the most efficient tools that has been utilized extensively to create genetic variation as well as for identification of key regulatory genes for economically important traits toward the crop improvement. We highlight the importance of genomic structural variation for the future genetic improvement of polyploid crops. 2007, Futamura et al.

In this review, we summarize the challenges of genome analysis in polyploid crops, describe the various types of genomic structural variation and the genomics technologies and data that can be used to detect them, and collate information produced to date related to the impact of genomic structural variation on crop phenotypes. For example, in … Tuskan GA, DiFazio S, Jansson S, Bohlmann J, Grigoriev I, Hellsten U, Putnam N, Ralph S, Rombauts S, Salamov A, Schein J, Sterck L, Aerts A, Bhalerao RR, Bhalerao RP, Blaudez D, Boerjan W, Brun A, Brunner A, Busov V, Campbell M, Carlson J, Chalot M, Chapman J, Chen GL, Cooper D, Coutinho PM, Couturier J, Covert S, Cronk Q et al (2006) The genome of black cottonwood, Vaishnav A, Kumari S, Jain S, Verma A, Tuteja N, Choudhary DK (2016) PGPR-mediated expression of salt tolerance gene in soybean through volatiles under sodium nitroprusside. Defining the role of each gene in the complex cellular machine and network is a formidable task. • Novel genetic techniques have been developed in recent years and are advancing rapidly. 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.

Previous Dept. 2008, Mace et al. This review articulates the role of histone modifications and DNA methylation in modulating biotic and abiotic stresses, as well as crop improvement. In the current scenario, the most critical challenge faced by the human race is to provide food security for a growing population. Both approaches are important for breeding new varieties and the need to identify new sources of genetic variation. Crop improvement has been a traditional issue to increase yields and enhance stress tolerance; however, crop improvement against abiotic stresses has been particularly compelling, given the complex nature of these stresses. 4 Arable"Land","A"Limited"Resource" Arable"land"projected"to"decline"" from"0.38"hectares"in"1970"to"" 0.15"hectares"per"person"in"2050" Total&land&on&earth:&& 12.8&billion&hectares& Land is a limiting … Biotechnology 9:957–962, Daei G, Ardekani MR, Rejali F, Teimuri S, Miransari M (2009) Alleviation of salinity stress on wheat yield, yield components, and nutrient uptake using arbuscular mycorrhizal fungi under field conditions.
