Deleterious Mutation Accumulation in Arabidopsis thaliana Pollen Genes: A Role for a Recent Relaxation of Selection.

An LRT statistic (twice the difference in log-likelihood between the two models) >9.210 indicated a highly significant difference ( P < 0.01; LRT > 5.991: P < 0.05) between the two models suggesting the existence of sites under positive selection within the tested gene ( Anisimova et al. 2003 ; Yang 2007 ).

In all five quantiles, d N /d S was higher within pollen genes than within sporophyte-specific genes (highly significant in the first three, marginally significant in the fourth after correction and nonsignificant in the fifth quantile; table 4 ).
