Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor

Table 3 Over-represented gene groups according to function

Function		Amount	Statistical p	% in sample	% in genome	Over-representation (-fold)
Cell wall	Cellulose synthase	4	1.38e-05	2.45%	0.08%	31.0
	Beta 1,3-glucano hydrolases	3	5.40e-03	1.84%	0.12%	15.3
	Pectin esterases	3	7.57e-03	1.84%	0.18%	10.2
	Breaking down	4	9.84e-03	2.45%	0.12%	20.2
Transport	Membrane Intrinsic Proteins	5	2.78e-06	3.07%	0.02%	135.7
Miscellaneous		23	1.07e-05	14.11%	0.18%	78.4

The abundance of these groups in our dataset versus their abundance in the tomato genome is shown. Over-representation was calculated as the ratio between the % abundance in immunoprecipitated samples and the % abundance in the whole genome. Statistical p-values are indicated.
