Bottom Line: After 5 days, the plants were found to have completely recovered.Early responses involved many cold-stress-responsive genes coding for, among many other things, C-repeat binding factor transcription factors, fatty acid desaturases, wax synthesis, and oligosaccharide metabolism.After long-term exposure to cold, a large proportion of gene down-regulation was found, including photosynthesis and plant growth genes.

Biological process and function GO-term-enriched graph of late long-term-induced unigenes in response to cold stress. The subset of annotated sequences was analysed. The node filter was set at FDR < 0.01. Bars for late long-term-induced unigenes are labelled with their corresponding P-values in the Fisher's exact test against the expressed control leaf unigenes.

DSU033F9: Biological process and function GO-term-enriched graph of late long-term-induced unigenes in response to cold stress. The subset of annotated sequences was analysed. The node filter was set at FDR < 0.01. Bars for late long-term-induced unigenes are labelled with their corresponding P-values in the Fisher's exact test against the expressed control leaf unigenes.

Mentions: We performed the GO-term enrichment analysis as above with the GO terms retrieved by Sma3s for 31 sequences from 64 over-expressed late long-term unigenes using a cut-off value of FDR < 0.01. The percentage of sequences that annotated for each ‘biological process' or ‘function’ GO term for both control leaves and early long-term COR unigenes is shown in Fig. 9. No ‘biological component’ GO term was found for the chosen FDR cut-off. It was observed that the most representative processes were related to organelle fusion, nucleus organization, and DNA integration (Fig. 9). Among 20 sequences associated with organelle fusion and nucleus organization, four Flavin Adenin (FAD)-binding Berberine-like unigenes (unigenes 254,633, 435,666, 525,595, and 313,705) were shared by both processes. Six sequences were associated with DNA integration. They were annotated as Ty3-gypsy subclass, Gag-pol polyprotein, retroelement polyprotein-like, Copia-type polyprotein, and integrase (unigenes 104,981, 285,292, 627,965, 95,624, 510,781, and 36,107). Thus, they are putative transposable elements (TEs, jumping genes).Figure 9.
