Ca2+作为细胞内、外信号的重要的第二信使，在向性运动的信号转导中起了重要的调节作用，着重综述了Ca2+在向光性和向重性运动的信号转导中的作用。

Ca2 + plays an important regulation role in regulation of signal transduction of tropism as the second messenger of inside and out of cells . The effect of Ca2 + on signal transduction during phototropism and gravitropism movements was summarized on stress .

植物向重性地基研究

Ground_Based Studies on Plant Gravitropism

该结果说明，胶质纤维的分化和木质部的增加对负向重性都是重要的；

These results indicate that not only the differentiation of gelatinous fibers but also xylem increment is important in the negative gravitropism .

道德内涵及其地位的历史性转变是通过二重性道德（义务的道德和愿望的道德）向一重性道德（义务的道德）转变而表现出来的。

The connotation of morality and the transformation of its historical status is shown through the dual morality ( the morality of obligation and the morality of willing ) becoming lingual morality ( the morality of obligation ) .
