Genes from wild relatives to improve drought resistance: case study on tomato

Stomata on a plant leaf


The wild relatives of tomato are native of the Andes and are adpted to extremely dry environments where they rely mostly on dew. This makes them potentailly very useful sources of genes or alleles for drought resistance and water use efficiency that have been lost through domestication and selection of cultivated tomato.

Through the nalysis of tomato lines carrying introgressions from the wild relative S. penellii, we identified putative candidate genes for improved leaf transpiration efficiency and ability of  to maintain turgor. Projects are available to test these candidates through analysis of mutants and transgenic lines.
