Cymbidium ensifolium is one of the national orchids in China, which has high ornamental value with changeable flower colors. To understand the formation mechanism of different flower colors of C. ensifolium, this research conducted transcriptome and metabolome analyses on four different colored sepals of C.

Article Synopsis
  • The basic helix-loop-helix (bHLH) transcription factors are important proteins found in many organisms that help regulate various biological processes, but they hadn't been comprehensively studied in orchids before this research.
  • In this study, 94 bHLH transcription factors were identified in orchids, divided into 18 subfamilies, with many linked to stress responses and hormone activities.
  • Analysis of gene expression revealed that 84 of these factors were expressed differently in sepals of various colors, suggesting their potential role in flower color through anthocyanin regulation, especially in specific bHLH subfamily genes.

Article Synopsis
  • * A total of 136 CeMYB transcription factors were identified, categorized into various classes, and organized into 20 phylogenetic clusters, suggesting their diverse biological functions.
  • * Analyses showed that these CeMYBs are mostly located in the nucleus, contain stress-responsive elements, and may play a key role in flower color variation, providing insights for further research on anthocyanin biosynthesis.
