Welcome to the PGSB Rye Genome Database

Rye (Secale cereale) is an important cereal crop mainly cultivated in Eastern and Northern Europe. The rye domestication started 7000 years ago (Neolithic Era) in the Near East and later in Europe. At the beginning rye has been considered a weed in wheat and barley fields (Sencer and Hawkes, 1980; Willcox, 2005) but its popularity gained due to its low requirements regarding soil and fertilization, as well as a good overwintering ability. These traits makes rye a perfect model for consequently improvement of closely related cereal crops like wheat (Triticum aestivum) and barley (Hordeum vulgare), which are less tolerant to abiotic stress.
Rye (Triticeae tribe) is an outbreeding diploid with a large, highly repetitive genome (1C = 8.1 Gbp) which has undergone a series of rearrangements in comparison to other grass genomes. A high-density gene-based marker map, chromosomal survey sequences from sorted rye chromosomes and global conserved synteny allowed us to analyze the rye genome organization and evolution.
