Fig. 2From: The flattened and needlelike leaves of the pine family (Pinaceae) share a conserved genetic network for adaxial-abaxial polarity but have diverged for photosynthetic adaptationMaximum likelihood (ML) trees and repertoire of polarity genes. a Rooted phylogenetic tree of the HDZIPIII genes. b Unrooted trees of YABBY genes. Ang, angiosperm; Gym, gymnosperm; Lyc, lycophytes. Numbers on the branches indicate the bootstrap values. c Repertoire of polarity genes in Pinaceae lineages. Red colors indicate the species with needlelike leaves; Black stars indicate that data were collected from the genome databasesBack to article page
