Canonical and Alternative Auxin Signaling Systems in Mono-, Di-, and Tetraploid Potatoes

It has long been known that the phytohormone auxin plays a promoting role in tuber formation and stress tolerance potatoes. Our study aimed to identify characterize complete sets of auxin-related genes presumably constitute entire signaling system potato (Solanum tuberosum L.). The corresponding were retrieved from sequenced genomes doubled monoploid S. DM1-3-516-R44 (DM) Phureja group, heterozygous diploid line RH89-039-16 (RH), autotetraploid cultivar Otava. Both canonical noncanonical pathways considered. Phylogenetic domain analyses deduced proteins supplemented by expression profiling 3D molecular modeling. ABP1-mediated appeared be well conserved. total number genes/proteins involved is 46 108 DM tetraploid Otava, respectively. Among studied potatoes, spectra expressed obviously associated with partly cultivar-specific quite different analogous spectrum Arabidopsis. Most found Arabidopsis have low probability potato. This was equally true for all cultivars used irrespective their ploidy. Thus, some important features (noncanonical) may variable species-specific.
