The genome of a model plant related to peach, cherry and cultivated
strawberry has been sequenced by a consortium of international
researchers that includes scientists with the Agricultural Research
The scientists announced the sequencing of the genome of woodland
strawberry over the weekend at the Plant and Animal Genome Conference
in San Diego, Ca. The project was funded by Roche Diagnostics.
Fragaria vesca, commonly known as the woodland or alpine strawberry, is
a member of the Rosaceae family, which consists of more than 100 genera
and 3,000 species. This large family includes many economically
important and popular fruit, nut, ornamental and woody crops, such as
almond, apple, peach, cherry, raspberry, strawberry and rose.
F. vesca has many traits that make it an attractive model system for
functional genomics studies. Its small size and rapid life cycle enable
researchers to conduct genetic analyses with great efficiency and low
cost. To determine the importance of a gene of interest, F. vesca can
be transformed in order to modulate the activity of that gene in the
plant. Most importantly, F. vesca has a relatively small genome, yet
shares most gene sequences with other members of the Rosaceae family,
making it an important tool for addressing questions regarding gene
ARS molecular biologist Janet Slovin, with the Genetic Improvement of
Fruits and Vegetables Laboratory in Beltsville, Md., created the nearly
inbred line used in the F. vesca genome sequencing project. Named
“Hawaii 4,” this line allowed the researchers to more easily program a
computer to piece the genome together from the relatively short lengths
of sequence data generated by modern sequencing machines.
Although the F. vesca genome is a model genome for the Rosaceae group,
critical regulatory gene functions will probably differ, hypothesizes
Slovin. Scientists can use the genome sequence to identify these genes,
to test their function in F. vesca, and to develop molecular genetic
markers for more rapid breeding of crops belonging to the Rosaceae
group. Slovin will use the genome to study and improve heat tolerance
during fruit production in strawberry.
