To identify an extra chromosome observed in interspecific hybrid between Torenia fournieri (2n=2x=18) and Torenia baillonii (2n=2x=16) at DNA level, 169 SSR markers were developed using fosmid and cDNA clone sequences and a partial linkage map was constructed in F_2 population of T. fournieri and T. violacea. Next, fosmid-FISH analysis has been conducted to screen fosmid clones derived from the extra chromosome, but the FISH signals of 19 clones tested did not formed on the extra chromosome. In addition, phylogenic analysis including other 7 Torenia species collected in south Asia suggests a hypothesis that T. baillonii lost the extra chromosome during the speciation.

为了确定在DNA级别的Torenia Fournieri（2n = 2x = 18）和Torenia baillonii（2n = 2x = 16）之间在种间杂交中观察到的额外染色体，使用Fosmid和Fosmid和cDNA Clone序列和部分链接图开发了169个SSR标记。接下来，已经进行了fosmid-fish分析以筛选源自额外染色体的fosmid克隆，但是在额外的染色体上未形成19个测试克隆的鱼信号。此外，包括南亚收集的其他7种多纳尼亚物种在内的系统发育分析表明，贝洛尼氏菌在物种形成期间失去了额外的染色体的假设。
