Pangenomics and single-cell transcriptomics uncover the genetic basis of continuous bearing trait in grapevine.

ABSTRACT: Grapevine (Vitis vinifera) is economically important for fresh consumption, winemaking, and drying. The circadian systems of flowering and fruit development are crucial for viticulture and yield formation. However, the genetic basis of continuous flowering and bearing has been rarely elucidated. Here, we integrate pan-genomics, comparative genomics, single-cell transcriptomics, and bulk transcriptomics to investigate the continuous flowering and bearing trait (CFB) in the 'Julian' grape, which bears fruits at different development stages from flower to mature berries simultaneously. Pan-genomics and comparative genomics discovered 558 unique structural variations (SVs) and eight genes enriched in flowering pathways exclusively in Julian, based on the newly generated haplotype-resolv
