求翻译：但是这只能说明SPS可能只是间接影响光合作用进而影响叶绿体结构，然而，SPS影响叶片亚细胞结构的真正原因和分子机理还有待进一步验证。是什么意思？

But this only shows the sps may only indirectly affect photosynthesis and thereby affecting the chloroplast structure, however, sps affect the real cause of leaf subcellular structures and molecular mechanism remains to be further validation.

However, this can only be explained SPS may only indirectly affect photosynthesis and thus affect chloroplasts SPS structure, however, affected leaves the cell structure and the elements of the real reasons for the acting is also subject to further validation.

But this only can explain SPS is only possibly the indirect influence photosynthesis then influence chloroplast structure, however, the SPS influence leaf blade Asia cell structure true reason and the molecular mechanism also waits for further confirms.

But it can only show that SPS may be only indirectly affect the photosynthesis and thus affecting the chloroplast structure, however, SPS subcellular structure in effect leaves the real causes and molecular mechanism is subject to further verification.
