Full-length transcriptome sequencing analysis of seedless kiwifruit

Recently, a new seedless kiwifruit cultivar, Chengxiang (Actinidia arguta) was discovered by field transplantation. It exhibited distinguishable characteristics such as parthenocarpy, unique flavor and appearance than other cultivated type. Flavonoids are known to play an important role in fertility and parthenocarpy in plants. However, the genes responsible for flavonoid biosynthesis in seedless kiwifruit remain largely unknown. In this study, we combined full-length transcriptome survey by PacBio single-molecule real-time (SMRT) sequencing, CHS gene family analysis and gene expression involved in flavonoid pathways to further enhance understanding of parthenocarpy.
