Fig. 3From: Genome-wide identification of PbrbHLH family genes, and expression analysis in response to drought and cold stresses in pear (Pyrus bretschneideri)Distribution and collinearity of the PbrbHLHs. Red lines along the circumference of the circle mark the positions of genes on chromosomes. The lines in different colors inside the circle indicate collinearity relationships among PbrbHLH genesBack to article page
