Dear Editor,Robertsonian(Rb)fusions contribute to the diversity in species karyotypes.However,how it occurs and propels evolution is still unknown,mainly due to the lack of a simple and efficient method for geneticall...
Parthenogenesis is one of the main, and most useful, methods to derive embryonic stem cells (ESCs), which may be an important source ofhistocompatible cells and tissues for cell therapy. Here we describe the derivat...

Drosophila lacertosa is widely distributed from northern India to Far East of Russia throughout China.We have studied geographical distributions of three kinds of chromosomal karyotypes,type D(2n=10,4 pairs of V-shape...
A karyotype of Trifolium repens constructed from mitotic cells revealed 13 pairs of metacentric and 3 pairs of submetacentric chromosomes including a pair of satellites located at the end of the short arm of chromosom...
The apple rootstock, A106 (Malus sieboldii), had 17 bivalents in pollen mother cells at meiotic metaphase 1,and 17 chromosomes in a haploid pollen cell. Karyotypes were prepared from root-tip cells with 2n= 34 chromos...
