Gene expression patterns of cell wall remodelling proteins implicated in the cold‐induced secondary dormancy. Transcript abundances in sugar beet seeds incubated at the indicated temperature regimes: red (10°C), blue (5°C), and purple (T _SD); for details of the transcriptome analysis, see Figure 4. For xyloglucan endotransglucosylase/hydrolases (BvXTH) and expansins (BvEXP), sums of transcripts are presented as z‐scores. See Figure S11 for additional genes, individual XTH genes and lists for the two XTH clusters, and Table S1 for the Beta vulgaris gene names and IDs. (a–g) Transcript abundances from the KWS310 transcriptome analysis. (h) RT‐qPCR analysis of transcript abundances of the contrasting KWS310 and KWS257 seedlots. See main text for gene abbreviations. Mean values ± SEM are presented. RT‐qPCR, reverse‐transcription quantitative polymerase chain reaction [Color figure can be viewed at wileyonlinelibrary.com]
