Fragile sites in domestic animal chromosomes: molecular insights and challenges.

abstract：:Plant meiosis studies have enjoyed a fantastic boom in recent years with the use of Arabidopsis thaliana as a model not only for molecular genetics and genomics but also for cytogenetics. In this article we describe a new protocol for immunolabelling meiotic proteins that allows the detection of a large range of prote...
