Table II. S. squalidus pistil-expressed genes that have been identified in at least two of the pistil preferential data sets from different species.

The study species used were Arabidopsis (Swanson et al., 2005; Tung et al., 2005), rice (Li et al., 2007), tobacco (Quiapim et al., 2009), and crocus (D’Agostino et al., 2007). Presence (+)/absence (−) is indicated for each species, followed by transcript numbers in parentheses.
