title: Plant sample from Oncidium PB2-1
design: Three-year-old plants were grown in 11cm12cm (diameter  height) pots filled with substrate, in a greenhouse at the Institute of Crop Sciences, Fujian Academy of Agricultural Sciences (FAAS) (Fuzhou, China). Leaf and pseudobulb samples were collected from plants with three developmental stages, young pseudobulb, inflated pseudobulb before inflorescence, flowering. The pseudobulb samples from after flowering plants were also collected. The flower samples were collected from five flower developmental stages from flowering plants. These samples were used for RNA extraction. For each RNA purification biological replicate, three plants were pooled to form a single sample. Two independent RNA samples were used for each experiment.
