| 描述信息 |
Taraxacum species consists of two types of species: rubber-producing dandelion and non-rubber-producing dandelion. The genome of rubber-producing dandelion Taraxacum kok-saghyz has yet to be assembled. However, a high-quality reference genome for rubber-producing dandelion and non-rubber-producing dandelion remain unexplored. Here, we present two genomes of Taraxacum species for genome comparison to reveal natural rubber (NR) biosynthesis pathway. Two polyploidization events respectively, including the common ancestral whole-genome triplication of the Eudicots (WGT-γ) and the unique round of polyploidization event, occurred in Taraxacum species. Comparative analyses uncovered a large number of genetic variations, including inversions, translocations, presence/absence variations, which might cause considerable protein divergences between the two species. All processes of NR-biosynthesis related pathway were found in the TK1151 and TM5 genomes, suggesting that possibly some unknown genes rather than SRPP and CPT in TK1151 may play critical roles in NR biosynthesis. This study will have large-ranging implications for the mechanism of NR biosynthesis and genetic improvement of NR content. |
