Deletion and tandem duplications of biosynthetic genes drive the diversity of triterpenoids in Aralia elata  Tandem duplication of genes drives the diversity of oleanane-type pentacyclic triterpenes in A. elata The colinearity relationship of CYP72A (a), CSLM (b), and two UGT73 (c and d) tandem duplication regions between A. elata and P. notoginseng. The syntenic blocks are connected by

 High-quality evergreen azalea genome reveals tandem duplication-facilitated low-altitude adaptability and floral scent evolutionCharacteristics of Rhododendron ovatum and its genome assembly. (a) Low-altitude and evergreen characteristics of R. ovatum. The genus Rhododendron contains five main subgenera, of which two subgenera (Rhododendron and Hymenanthes) commonly called ‘rhododendron’ are mainly distributed in alpine and subalpine zone, and the other three (Azaleastrum, Tsutsusi, and Pentanthera) commonly called ‘azalea’ are distributed in

 Whole genome duplications in plants: an overview from ArabidopsisFig. 1.Chromosome status in the genus Arabidopsis after polyploidization events. A. arenosa and A. thaliana persist as both diploid and autotetraploid. Allopolyploid A. suecica is formed by a single hybridization event between A. thaliana and A. arenosa. Mechanisms leading to autotetraploids and allotetraploids are indicated. Other non-shown genus members also suffer polyploidization. Thus, A. lyrata autotetraploid are also frequent and A. kamchatica is originated from

 解碼牛樟基因體闡明被子植物的演化 Stout camphor tree genome fills gaps in understanding of flowering plant genome evolutiona, Schematic representation of the intragenomic relationship among the 637 synteny blocks in the SCT genome. Synteny blocks (denoted by peach blocks) were assigned unambiguously into five linkage clusters representing ancient karyotypes and are colour coded. Purple blocks denote the synteny block assigned in the first
