Transcriptional Regulations on the Low-Temperature-Induced Floral Transition in an Orchidaceae Species, Dendrobium nobile: An Expressed Sequence Tags Analysis
Figure 5
Time-course transcript profiles of selected flowering-relevant genes during the vernalization process. Relative expression levels of each selected genes after exposing at 15°C/10°C (day/night) for 0, 5, 10, 20, and 30 days are shown. Total RNA were isolated and were reverse transcribed to cDNA that served as templates in real-time qPCR assays. RQ values of each gene relative to 0 d-bud samples were log 2-transformed (-axis) and plotted against the time periods (-axis). The positive and negative values indicate the vernalization-induced activation and repression, respectively. The error bars are calculated based on the (RQMin and RQMax) confidence interval (95%).
