The genome of Prunus mume

Nature, Qixiang Zhang et al.

Abstract – Prunus mume (mei), which was domesticated in China more than 3,000 years ago as ornamental plant and fruit, is one of the first genomes among Prunus subfamilies of Rosaceae been sequenced. Here, we assemble a 280M genome by combining 101-fold next-generation sequencing and optical mapping data. We further anchor 83.9% of scaffolds to eight chromosomes with genetic map constructed by restriction-site-associated DNA sequencing. Combining P. mume genome with available data, we succeed in reconstructing nine ancestral chromosomes of Rosaceae family, as well as depicting chromosome fusion, fission and duplication history in three major subfamilies. We sequence the transcriptome of various tissues and perform genome-wide analysis to reveal the characteristics of P. mume, including its regulation of early blooming in endodormancy, immune response against bacterial infection and biosynthesis of flower scent. The P. mume genome sequence adds to our understanding of Rosaceae evolution and provides important data for improvement of fruit trees.

  1. I have been absent for some time, but now I remember why I used to love this blog. Thank you, I’ll try and check back more often. How frequently you update your web site?

  2. It’s a pity you don’t have a donate button! I’d most certainly donate to this superb blog! I guess for now i’ll settle for book-marking and adding your RSS feed to my Google account. I look forward to brand new updates and will share this website with my Facebook group. Talk soon!
