De novo genome assembly, transcriptome sequencing of flower buds at multiple developmental stages, differentially expressed gene screening and regulatory pathway characterization were conducted.
Key Findings
Chromosome-level genome assembly of Gentiana rigescens was completed, with systematic functional annotation of genes involved in floral development.
Key transcription factors and endogenous hormone regulatory pathways determining recurrent flowering behavior were screened.
Precise genetic targets were offered for directional molecular improvement of flowering traits in medicinal and ornamental Gentiana varieties.
The corresponding article The Gentiana rigescens genome and transcriptome for the investigation of flower repetitive blooming was published in BMC Biology (IF: 7.1).

Summary:A high-quality chromosome-scale genome of Gentiana rigescens was de novo assembled; transcriptomes sampled across distinct flowering stages were analyzed to identify core regulatory modules governing the trait of repeated flowering throughout the year.
