Abstract:

Although knowledge about plant root phototropism, especially negative phototropism is clearly of high importance, the area not only involves many research fields and knowledge, but also has important ecological significance and application value. In this review, we retrospected the history of study on root phototropism, summarized the study on mechanisms of negative phototropism. The relationships between gravi- and phototropism and ecological significance of root phototropism are also discussed. Finally, problems to be solved and future research directions in this area are prospected.

Key words: root; negative phototropism; photoreceptor; retrospection; prospection
