Microarray (upper colored rows) and qPCR expression (lower grey colored rows) against each 19 MADS-box genes in
under control (C1&K1), 4°c (C2&K2), 0°c (C3&K3), −2°c (C4&K4), and −4°c (C5&K5) temperature treatments. Here C and K stand for ‘chiifu’ and ‘kenshin’ two inbred lines of B. rapa respectively. Responsive genes in different temperature from different MADS-box groups have been shown on the left side. Color bar at the base representing differential expression in microarray. Values denoted by the same letter did not differ significantly at P < 0.05 according to Duncan’s multiple range tests.
