T plant A. thaliana WT (Col-0) and Atpao5-2 mutant were grown vertically on MS agar

T plant A. thaliana WT (Col-0) and Atpao5-2 mutant were grown vertically on MS agar media or 5 lM T-Spm containing MS agar media for 14 days. Below manage situation (MS), WT and Atpao5-2 grew comparably (Fig. 1a, left panel). In presence of five lM T-Spm (T-Spm), the root growth was inhibited with comparable extent whereas the growth on the PDE6 web aerial part of Atpao5-2 was AMPA Receptor Agonist Storage & Stability severely disrupted in comparison to WT plants (Fig. 1a, b). This development arrest was T-Spm-specific. Other polyamines like Place, Spd and Spm don’t have such effects (data not shown). At greater T-Spm concentration (ten lM) a extreme arrest in development was observed (Kim et al. 2014). Cell wall, lipid, and secondary metabolism were affected in T-Spm treated Atpao5-2 To uncover the molecular bases of T-Spm effect, gene expression analyses were performed by MACE (Zawada et al. 2014). In low dose (5 lM) T-Spm treated WT (WTTs), 1,398 genes have been differentially expressed C twofold compared to untreated WT (Fig. 1c). On the other hand, in Atpao5-2, three,186 genes were modulated with C twofold difference in 5 lM T-Spm treatment (Fig. 1c). Four hundred nine genes were impacted in common by T-Spm in WT and Atpao5-2 (Fig. 1c). Additional, to determine the metabolic pathways which are affected by the differential expression in the 3,186 genes, Mapman analysis was performed. Cell wall-, lipid- and secondary- metabolisms had been strikingly impacted in 5 lM treated Atpao5-2 (Fig. 2a), whereas other pathways like TCA cycle-, amino acidmetabolisms and photosynthesis were not much impacted (Fig. 2a). The cell wall, pectin metabolism, cell wall proteins and degradation processes have been hugely modulated (Fig. 2b).
