Genome structure and emerging evidence of an incipient sex chromosome in Populus

T Yin, SP DiFazio, LE Gunter, X Zhang… - Genome …, 2008 - genome.cshlp.org
The genus Populus consists of dioecious woody species with largely unknown genetic
mechanisms for gender determination. We have discovered genetic and genomic features in
the peritelomeric region of chromosome XIX that suggest this region of the Populus genome
is in the process of developing characteristics of a sex chromosome. We have identified a
gender-associated locus that consistently maps to this region. Furthermore, comparison of
genetic maps across multiple Populus families reveals consistently distorted segregation …
