Identification of woodland strawberry gene coexpression networks

Authors: Smith, Lisa M.

What we think of as a strawberry is botanically not a berry or even a fruit, but rather multiple fruits (achenes that contain the seeds) on the outside of a swollen receptacle. This technicality aside, strawberries are both economically important and a useful system in which to study seed-fruit communication. While cultivated strawberries have a complex octoploid genome, one of their likely progenitors, the woodland strawberry (Fragaria vesca; Fig. 1), is a rapidly growing model system for the Rosaceae family due to its short generation time and capacity to be transformed. A draft of the woodland strawberry diploid genome sequence was released in 2011 (Shulaev et al., 2011), and the recent publication of a high-quality genome based on PacBio sequencing has added almost 1,500 genes to the annotation (Edger et al., 2018). Genetic and epigenetic resources have also been developed for this species (Xu et al., 2016; Hilmarsson et al., 2017).
