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. Crit Rev Plant Sci 13:121–138, Souza RD, Ambrosini A, Passaglia LMP (2015) Plant growth-promoting bacteria as inoculants in agricultural soils. have received little attention of researchers so far despite their major role in plant–soil interactions (Sheshshayee et al. Determination of entire genome sequences is only the first step in understanding the inner workings of an organism. 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). Biotechnology has offered tremendous scope and potential to conventional methods of crop improvement, crop protection, crop quality management and other horticultural traits. 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. Plant Introduction 2. In the last few years there has been rapid progress in the area of plant structural and functional genomics. 70.32.23.12. Genetic crop improvement can contribute towards solving this complex problem. This review articulates the role of histone modifications and DNA methylation in modulating biotic and abiotic stresses, as well as crop improvement. 5). 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. 2005) and genomics … 2007, Futamura et al.

The role of genomics in crop improvement Mike Bevan UPOV, Geneva •Supplying sufficient food in the 21 century •What is sustainable agriculture? Not affiliated In addition, genomes contain hundreds to thousands of genes many of which encode multiple proteins that interact and function together as multicomponent systems or apparatuses for accomplishing specific cellular processes. They include techniques commonly referred to as ‘genome editing’ that allow targeted changes to be made to genomes, such as adding, removing or replacing DNA at specified locations. Genome mapping is useful in several ways. J Plant Physiol 66:617–625, El-Daim IAA, Bejai S, Meijer J (2014) Improved heat stress tolerance of wheat seedlings by bacterial seed treatment.
