Additional file 10: of Evolution and expression analysis reveal the potential role of the HD-Zip gene family in regulation of embryo abortion in grapes (Vitis vinifera L.)

Figure S4. Expression of HD-Zip genes in somatic embryo of TS. PEM: proembryogenic masses; GE: globular embryo; HE: heart embryo; TE: torpedo embryo; CE: cotyledon embryo. All qRT-PCR experiments were employed with three biological duplications, and each duplication was repeated in triplicate, standard deviations are shown with error bars. Significant (P < 0.05) differences were used. The graphs are arranged as classification in phylogenetic tree. (TIFF 4628 kb
