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

From: Assessment of shared alleles in drought-associated candidate genes among southern California white oak species (Quercus sect. Quercus)

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
(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
