While all plastomes of Piper and Peperomia had the same gene content and order, there were informative structural differences between them. First, ycf1 was more variable and longer in Piper than Peperomia, extending well into the small single copy region by thousands of base pairs. We also discovered previously unknown structural variation in 14 out of 25 Piper taxa, tandem duplication of the trnH-GUG gene resulting in an expanded large single copy region. Other early-diverging angiosperms have a duplicated trnH-GUG, but the specific

In the fields of satellite formation, large-scale manufacturing, and ultra-precision machining, high-precision ranging based on the femtosecond laser is one of the necessary technologies. However, the fluctuations of the air refractive index and the limited tuning range of repetition rate restrict the measurement precision and range. Using only one femtosecond comb that corrects the air refractive index simultaneously, a method for ranging without the dead zone of measurement is described. A delay optical path is established in the rang
