Dhaka Nov. 6, 2013.In an online article, titled, “Draft genome sequence of the mulberry tree Morus notabilis, published in the November, ’13 issue of Nature Communications, Shougong Zhang and 54 Associates affiliated with 10 Institutions including one each from Canada and USA
reported the draft genome sequencing of the mulberry tree, Morus notabilis.
They observed 128 Mb of repetitive sequences and 29,338 genes. Transcriptomestudy confirmed the Mulberry gene sequences (60.8%) which appear to have evolved ~3 times faster than other Rosales, perhaps facilitating the species’ spread worldwide.
Furthermore, they suggest that a neopolyploid series have emerged with new duplications conferring benefits to this mulberry tree species. Five predicted mulberry miRNAs have been reported in the haemolymph and silk glands of the silkworm, suggesting the plant–herbivore relationship at molecular levels in this taxon.
The identification and analyses of
mulberry genes have led the authors postulate that rapid rate of evolution in this
mulberry species will accelerate the improvement of mulberry plants.
