扁桃属

The internal transcribed spacer regions of nuclear ribosomal DNA from 8 species of subgenus Amygdalus were sequenced, and analyzed together with other ITS data of 18 species representing subgenus Cerasus, subgenus Armeniaca and subgenus Primus by using of Padus racemosa Gilib. and Padus buergeriana Yüet Ku as outgroup for studying phylogeny of subgenera in stone fruit plants.

采用核核糖体DNA内转录间隔区对桃亚属的光核桃、甘肃桃、新疆桃、山桃、陕甘山桃、扁桃、野扁桃基因序列测序及来源于GenBank的李、杏、梅、樱的18个种的ITS区基因序列，以稠李和楼木、梅和杏分别作为对桃亚属及其近缘亚属植物、桃亚属各种类的外类群，进行系统发育树的建立。

This results gave a clearly outlook of the genetic relationship and genetic diversity level among Amygdalus plants germplasm.

这个结果也表明了扁桃属植物种质资源的演化关系和遗传多样性水平。

Above these species, a tetrachotomy separated four monophyletic groups, the first one consisting of P. mira and P.

野扁桃和矮扁桃在桃亚属中其它种的基部，紧接着是扁桃，它单独占有一类位置。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
