The tonoplast shows considerable invaginations . 液泡膜显示出相当大的内陷。
2.
Endothorax is composed of invaginations of the tergal, pleural and sternal regions of each thoracic segment . 胸内骨是由各胸节背、侧、腹部的内陷构成。
3.
The internal lamellae originate from an invagination of the inner of double membrances that surround the plastid . 片层起源于围着质体双层膜的内膜向内折伸。
4.
To verify the integration of st901 gene into transgenic plants genome , the stable transgenic plants were analyzed by pcr and southern blotting . the aberrant phenotypes were observed in pollens and anthers of the transgenic plants . most of pollen grains in the transgenic plant were distorted , shrunken , invagination and not stained with the solution of acetocarmine 通过对转基因植株花粉、花药形态的观察和花粉活力的测定，表明st901启动子驱动的st901基因在转基因植株中的表达造成花粉严重败育，花粉粒皱缩，扁瘪、塌陷，缺乏内容物；转反向表达载体的马铃薯花粉育性仅为对照的5 . 2 ，育性下降94 . 8 。
