Alien chromosome introgression transferring characters into bread wheat

In situ hybridization is now widely used to identify the nature and size of chromosome, chromosome arm and chromosome segment introgressions from alien or wild species in plant breeding lines. The molecular cytogenetics research group has several projects investigating introgression of chromosomes into wheat from rye, Thinopyrum (2x and 6x), Aegilops and other species or…

Mateus Mondin University of Sao Paulo Brazil: collaborator

We are collaborating with Professor Doctor Mateus Mondin from the University of São Paulo, ESALQ, Piracicaba, Brazil, on repetitive DNA evolution in Medicago DNA sequences, and its contribution to genome evolution and variation. The environmental, nutritional (animal, and plant through nitrogen fixation) and economic importance of this family, combined with the availability of large amounts of legume DNA…
