Changes in transcriptomic landscape between JB and LFP floral buds. (a) PCA showing the transcriptomic relationships. (b-c) Number of differentially expressed genes (DEG) (Down, down-regulated, and Up, up-regulated) in LFP compared to JB floral buds during chilling (b) and warm (c) treatments. (d-f) Altered expression amplitude and trajectory of DAM4 in JB and LFP flower buds.
