Gene expression patterns of major dormancy and maturation, histone modifiers and cold signalling components implicated in the cold‐induced secondary dormancy of sugar beet. Transcript abundances in sugar beet seeds incubated at the indicated temperature regimes: red (10°C), blue (5°C), purple (T _SD), for details of the transcriptome analysis see Figure 4. For late embryogenesis abundant (BvLEA) and oleosin (BvOLE) genes, the sums of transcripts are presented. See Figures S8, S9 and S10 for additional genes, individual LEA genes and master regulator interactions, and Supporting Table S1 for the Beta vulgaris gene names and IDs. (a–c) Transcript abundances from the KWS310 transcriptome analysis. (b) 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]
