Novel cell wall formation after chromosome addition
After mitosis a new cell wall forms in the middle of the
telophase cell through fusion of Golgi-derived vesicles.
In this issue, Cheng et al. reported an abnormal cell
wall-formation caused by addition of the rye 5RS chromosome
to common wheat (CS+5RS). Multicellular sacs, which were visible in the GISH image, were observed in the CS+5RS root tip. In addition, chromosome instability was also found in such plants. The paper proposed that a deleterious factor is present on
the 5RS region. See pages 503–509 for details.[Detail] ...
