Expression patterns analysis of SF1 genes in several plants. a RT-PCR analysis of AtSF1 and PtSF1 associated with their isoforms expression in roots, shoots, leaves, and flowers. Gene models of each isoform (AtSF1 and PtSF1) are indicated (black, coding region; white, non-coding untranslated regions). RNA samples of mannitol treatment were prepared from 7-day-old seedlings at the exposure to 350 mM mannitol. The Arabidopsis actin2 and the poplar 18S rRNA gene were used as the internal expression control. b Real-time RT-PCR expression analysis of AtSF1 and PtSF1 associated with their isoforms. c Expression patterns of Arabidopsis and Solanum tuberosum (potato) SF1 genes. Expression data were obtained from the plant eFP browser microarray datasets, transformed by Lg conversion and presented as a heatmap. Red colour represents high levels of transcript abundance, and blue represents low transcript abundance
