Identification and Expression Analysis of the <i>bHLH</i> Gene Family in <i>Rhododendron</i> × <i>pulchrum</i> Sweet with Different Flower Colors.

ABSTRACT: Basic helix-loop-helix (bHLH) transcription factors play significant roles in plant growth and organ development and diverse biochemical processes. However, the function of bHLH transcription factors in woody plants is not fully understood. In this study, the bHLH gene family in Rhododendron × pulchrum Sweet was identified and characterized using whole-genome data. A total of 109 bHLH family genes (RpbHLHs) were identified in R. pulchrum, and their expression levels were analyzed in flowers of different colors and developmental stages. The results showed that the RpbHLH family is divided into 24 subfamilies. Chromosomal localization and collinearity analyses revealed numerous duplication events during evolution, which is
