Table 5 Branch-site analysis of hsp-90 sequences grouped according to GA-binding status

From: Hsp-90 and the biology of nematodes

  Number of branches   Parameter estimates under free model dN/dS  
Clade All foreground LRT statistic p0a p1b p2c background foreground Sites under positive selection
GA binders 27 7 0.00 0.984 0.012 0.004 0.014 1.00 n/a
GA non-binders 27 20 0.00 0.978 0.004 0.18 0.014 1.00 n/a
  1. n/a not available. Number of branches: count of branches partitioned as foreground. LRT statistic: 2 times log likelihood difference of fixed versus free nested models.
  2. a Proportion of sites in category p0 where selection is purifying throughout the tree (0 < ω0 < 1).
  3. b Proportion of sites in category p1 where selection is neutral throughout the tree (ω1 = 1).
  4. c Proportion of sites in category p2 where selection is positive in foreground branches; sum of category 2a: purifying selection in background but positive selection in foreground (0 < ω0 < 1, ω2 > 1); and category 2b: neutral selection in background but positive selection in foreground (ω1 = 1, ω2 > 1
