Fig. 1From: Evolution and expression analysis reveal the potential role of the HD-Zip gene family in regulation of embryo abortion in grapes (Vitis vinifera L.)The phylogenetic tree of grape HD-zip genes. Members of the HD-zip genes from grapevine, Arabidopsis, maize and rice are marked: pink, purple, blue and turquoise, respectively. The phylogenetic tree was generated by MEGA 5.0 using the Neighbor-Joining method, bootstrap test (1000 replicates), two new identified genes were labeled by red starBack to article page
