The Boyce Thompson Institute\u2019s Computational Biology Center (BCBC) in collaboration with RWTH Aachen University has released an annotated genome sequence for Solanum lycopersicoides<\/em>, a wild relative of tomato.<\/p>\n

The genome has been assembled to near chromosome scale using Next Generation Sequencing (NGS) technologies. The S. <\/em>lycopersicoides<\/em> genome sequence <\/a>and accompanying annotation provide valuable new information on traits that dramatically affect crop yields, such as pest\/pathogen resistance and cold tolerance.<\/span><\/p>\n

Tomato is one of the world\u2019s largest value vegetable crops, making it a research priority for crop scientists. Recently, yields have been adversely affected by cold spells, pests, and pathogens including bacterial speck disease.<\/p>\n

While there is an extensive library of genomic information currently available for cultivated tomato, close relatives such as S. lycopersicoides<\/em> encompass untapped genetic value for breeders and research scientists. S. lycopersicoides<\/em> is notable for its ability to withstand cold weather and to resist infection by Pseudomonas syringae<\/em>, the pathogen that causes bacterial speck.<\/p>\n

The new genome sequence offers the opportunity for innovative breeding programs that may hold the ability to confer S. lycopersicoides<\/em>\u2019 desirable traits to marketable tomato varieties.<\/p>\n

Years of inbreeding and domestication have caused cultivated tomato varieties to lose tremendous amounts genetic diversity. Because wild varieties have not gone through these bottlenecks, they retain much of this diversity.<\/p>\n

\u201cS. lycopersicoides<\/em> retains several economically valuable traits, representing a wealth of genetic knowledge that does not exist in cultivated tomato and thus is not immediately available to scientists\u201d says Susan Strickler, who was involved in the project and is Director of the BCBC.<\/p>\n

The differences between the cultivated and wild species make it difficult to map wild tomato genes to the traditional tomato reference genome. The team used high-quality PacBio sequence alongside RNA sequence and transcriptome data to assemble and annotate the new genome.<\/p>\n

Moving forward, the BCBC will work with collaborators to develop mapping populations for the characterization of economically important traits that directly affect crop yields. The information therein will be valuable for diverse stakeholders including research scientists, breeders, growers, private corporations, and ultimately, consumers.<\/p>\n
