Conclusion Sauropus androgynus has certain genetic toxicity of chromosomal aberration induction and its molecular mechanism needs further investigation.
This paper reviewed the chromosomal engineering in the aspects of double diploid, hetero-additive line, hetero-replacement line, exchange line, monosome one incomplete chromosome systems.
Chromatin The loose network of threads seen in nondividing nuclei that represents the chromosomal material, consisting of DNA, protein (mainly histone), and small amounts of RNA.
