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

Table 2 Regulation of protein isoforms in synthetic Brassica napus.

	Stem		Root
Group of isoforms showing identical patterns of regulation	44	42.3%	39	47.6%
Group of isoforms showing opposite patterns of regulation	25	24.0%	12	14.6%
Group of isoforms showing different patterns of regulation	35	33.7%	31	37.8%
Total	104		82

For each organ, protein identification data were used to assess isoforms. Groups of isoforms that comprised spots sharing the same pattern of regulation (i.e. all spots up-regulated compared to the mid parent value, all spots down-regulated or all spots displaying additivity) were designated as "Group of isoforms showing identical pattern of regulation". Groups of isoforms that encompassed up-regulated and down-regulated spots were designated as "Group of isoforms showing opposite patterns of regulation". Groups of isoforms that included additive and non-additive spots (amongst which non-additive spots shared identical patterns of regulation, i.e. up-regulation or down-regulation) were designated as "Group of isoforms showing different patterns of regulation".
