is a significant traditional Chinese horticultural crop, valued both economically and ornamentally. The APETALA2/ethylene response factor (AP2/ERF) transcription factors play crucial roles in regulating growth, development, cell differentiation, and responses to both biotic and abiotic stresses in plants. However, the regulatory functions of AP2/ERF factors in remain poorly understood.

Bamboo orchid (), a fast-growing evergreen terrestrial orchid with year-round flowering capacity, exhibits limited germplasm resources for white floral variants despite its ornamental significance. This study investigates the molecular basis of natural white flower formation through comparative analysis of purple- and white-flowered variants across bud, post-bud, and blooming stages. Histological examination revealed anthocyanin accumulation restricted to two to three upper epidermal cell layers in purple petals, while white petals showed complete pigment absence.

However, studies on LBD genes in the Orchidaceae family remain limited. To our knowledge, this is the first systematic investigation of the LBD gene family in Cymbidium, a genus that exhibits remarkable species and trait diversity within the Orchidaceae.

The Chinese orchids symbolise nobility and gentility in China, and the variation of leaf color makes Cymbidium sinense more diversified and valuable. However, its color variations especially at the protein level still remain largely unexplored. In this study, the proteomics and phosphoproteomics of Cymbidium sinense leaf color variation mutants were studied.

However, the bud activation mechanism remains elusive. This study evaluates the multi-omics across six stages of flower development, along with functional analysis of core genes to decipher the innate mechanism of floral bud initiation and outgrowth in the Chinese orchid .

Nevertheless, the () gene family plays significant roles in the control of flowering, and its functions in Orchidaceae have been minimally explored. This research identified 68 potential genes within seven orchids' complete genome, divided into three groups (groups I, II, and III) via a phylogenetic tree.

All one-flowered have additional lateral buds in the apical bract that fail to develop. In this study, an exogenous gibberellin (GA) application promoted flowering of by inducing its early bolting instead of the floral transition of dominant flowers.
