Table 3 Drought genes in hybrid PR-22 lacking variants found in Q. engelmannii allele, as candidates for genes involved in local adaptation to warm or dry habitats
Gene (transcriptome contig) | Biallelic variants | engelmannii-fixed variants | Variants with no Q. engelmannii allele in hybrid PR-22 | % Identity to Arabidopsis | Uniprot Protein Name | Gene | Uniprot Function Description |
|---|---|---|---|---|---|---|---|
m01oak02926cC (also in Table 2) | 109 | 42 | 18 | 87% | Phosphoenolpyruvate carboxylase 1 | PPC1 | Through the carboxylation of phosphoenolpyruvate (PEP) it forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. Contributes probably to the adaptation to inorganic phosophate (Pi) deprivation |
m01oak03200CC (also in Table 2) | 66 | 46 | 11 | 79% | Polyol transporter 5 | PLT5 | Plasma membrane broad-spectrum sugar-proton symporter. Mediates the uptake of linear polyols such as sorbitol, xylitol, erythritol or glycerol. Can transport the cyclic polyol myo-inositol and different hexoses, pentoses (including ribose), tetroses and sugar alcohols. |
m01oak01188Ct | 7 | 5 | 1 | 58% | Yellow leaf specific gene 9 | YLS9 | Up-regulated in leaves during natural senescence |
m01oak04613CC | 43 | 12 | 3 | 68% | ACT domain-containing protein | ACR8 | May bind amino acids; induced by abscisic acid (ABA), and cold and salt stresses |
