COMMON DEFENSE PROMOTER
MOTIFS
Step2:
Ten sequence motifs, conserved among defense genes, were selected. Frequencies
of each motif were compared among different groupings of sequences.
Table 14. Occurrence frequencies of DNA motifs
in defense and non-defense genes.

Note: "a" the number in round bracket is the size of dataset
in kilo-basepair (kb); "b" frequencies (absolute repeat numbers) of DNA
motifs occurred in dataset; "c" frequency ratio (relative repeat numbers)
of DNA motifs occurred in dataset after normalization (frequencies/10-kb);
"d" underlined numbers were used to identify DNA motifs which occur more
than twice as often in one dataset versus the other dataset.
