Genomics Approaches for Crop Improvement against Abiotic Stress

Figure 2

Example of colinearity between grass genomes. Analysis of conserved gene sequences between barley (H. vulgare) and rice (O. sativa) shows that many genes are found in colinear (syntenic) order. In this example, chromosome 2 of barley (Hv2, centre) is compared with chromosomes 4 and 7 of rice (Os4 and Os7). Each colored line represents a gene conserved between the two chromosomes, with the color indicating the strength of the syntenic relationship. It is clear that many genes from both ends of Hv2 are colinear with the ends of Os4, while the centre of the chromosome is largely colinear with Os7, but in the reverse order.
