Differential regulation of gene products in newly synthesized Brassica napus allotetraploids is not related to protein function nor subcellular localization

Table 3 Protein isoforms amongst spots displaying additivity and non-additivity in Brassica napus.

	Stem				Root
	Spots displaying additivity		Spots displaying non-additivity		Spots displaying additivity		Spots displaying non-additivity
Number of identified spots	143		234		140		126
Number of protein isoforms	37	25.9%	117	50.0%	46	32.9%	91	72.2%

Significantly more isoforms were found amongst spots displaying non-additivity than amongst spots displaying additivity (χ² tests, P-values < 0.05, P-value = 3.76^e-6 in the stem and P-value = 1.42^e-10 in the root).
