if, however, the root cell is one of the rare tetraploid cells (a cell having four sets of chromosomes that arise spontaneously in the root), it may develop into a nodule.
如果这个根细胞是罕见的四倍体细胞(一种在根部自然拥有四套染色体的细胞),它就可能生长成为根瘤。
cytodynamic detection showed that the tetraploid cells were the majority.
细胞动力学检测显示以四倍体细胞为主;
chromosome count showed that the plants, containing non tetraploid cells besides amphidiploid, were chimeras.

it showed that tetraploid cells underwent more apoptosis when they were cultured along with diploid cells for 2 to 7 days than cultured alone.
结果表明,共培养2-7天内,混合培养的四倍体凋亡率与单独培养时差异显着;
results in aluminum electrolytic workers'peripheral lymphocyte chromosome, the percentage of tetraploid cells was higher than that of carbon workers and normal people, having significant difference.
结果铝电解工人外周血淋巴细胞染色体中四倍体细胞率高于碳素工人和正常人群,具有显着性差异;
the identification results of cell ploidy in the material induced showed that most strains were mosaic with diploid and tetraploid cells at average levels of 79.4% and 20.6% respectively.
