Fig. 1From: The GRAS gene family and its roles in seed development in litchi (Litchi chinensis Sonn)Phylogenetic tree of the GRAS gene family in litchi, rice, and Arabidopsis. The phylogenetic tree was constructed using Maximam-Likelihood (ML) method by MEGA7.0. Subfamilies were marked by bold yellow lines or orange lines in the external circle. The pink circles, green triangles and blue stars represent GRAS genes from litchi, Arabidopsis and rice, respectivelyBack to article page
