Site-directed mutagenesis and fitness assays were carried out as described previously (Domingo-Calap et al. 2009; Peris et al. 2010; Sanjuán 2010).
Sample text:```Quantitative geneticists have documented numerous cases of such interactions (Stuber et al. 1992; Ragot et al. 1995; Cockerham and Zeng 1996; Melchinger et al. 1998).```

Sample text:```Our results further confirm previous findings on the differential regulatory mechanisms for Hoxa3 and Hoxb3 expression in r5 and r6 by kreisler (Manzanares et al., 1997, 1999a,b, 2001).```
Sample intent: result



Sample text:```A number of studies have been published recently, which analyze the location, orientation, and identity ofmacromolecular complexes, based on the outcome of template-matching (Brandt et al., 2009; Ortiz et al., 2010).```
Sample intent: method



Sample text:```Because previous studies indicated that hexapeptides bind the junction core (29, 32), we tested two junctions, one with an AT-rich core and the other with a GC-rich core (Fig.```

Sample text:```Two days after transfection, cells were harvested and D2 activity was measured in lysates using HPLC, as described previously (20).```
Sample intent: background



Sample text:```Our genealogy, based on many alleles but only the first exon of bindin, is not entirely consistent with that of McCartney and Lessios (2004), based on fewer alleles but incorporating the entire molecule.```
Sample intent: result
Sample text:```Unlabeled DNA substrates containing consensus 12-RSS, 23-RSS, Hox11 or non-specific DNA sequences (DAR81/82) were prepared from oligonucleotides described previously [11,24].```

Sample text:```Previous studies have shown that sialome genes were subject to strong ancient selective pressures that have resulted in species-specific adaptations (Varki 2001; Angata et al. 2004; Altheide et al. 2006; Varki & Gagneux 2009), suggesting that they likely evolved in response to ancient pathogens The function of sialome genes, i.```

Sample text:```We screened for potential TF binding sites using STAMP [59], with the motifs’ position weight matrices (PWMs) retrieved from the TRANSFAC database [60].```

Sample text:```We also hypothesized that variation in seed mass should decrease in populations subjected to the strongest directional selection pressure (see [29]), which in this case is more arid areas where seed mass is known to be a key determinant of fitness [35,39].```
