Table 2 Drought genes that contain variants that are “fixed” in Q. engelmannii and at low frequency and under-represented across 20 scrub oak samples
Gene (transcriptome contig) | Biallelic variants | engelmannii-fixed variants | Scrub oak variants with less than 10% engelmannii | % Identity to Arabidopsis protein | Uniprot Protein Name | Gene | Uniprot Function Description |
|---|---|---|---|---|---|---|---|
m01oak10430CC | 163 | 138 | 8 | 80% | CHY-type/CTCHY-type/RING-type Zinc finger protein | None | none |
m01oak03512CC | 71 | 55 | 7 | 71% | Monosaccharide-sensing protein 3 | MSSP3 | Sugar transport |
m01oak02926cC | 109 | 42 | 7 | 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 |
m01oak01922jc | 71 | 49 | 5 | 92% | Cellulose synthase A catalytic subunit 2 | CESA2 | Catalytic subunit of cellulose synthase terminal complexes (‘rosettes’), required for beta-1,4-glucan microfibril crystallization, a major mechanism of the cell wall formation. Involved in the primary cell wall formation. |
m01oak00521CC | 61 | 53 | 3 | 87% | Heat shock 70 kDa protein 10, mitochondrial;Mitochondrial HSO70 2 isoform 2 | HSP70 | In cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage (By similarity). |
m01oak09381CC | 22 | 21 | 2 | 81% | Amino acid permease 3 | AAP3 | Amino acid-proton symporter. Stereospecific transporter with a broad specificity for GABA, tryptophan and both neutral and basic amino acids. High affinity transport of cationic amino acids. |
m01oak03200CC | 66 | 46 | 2 | 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. |
m01oak01473cC | 42 | 33 | 1 | 77% | Aspartic proteinase A1 | APA1 | Involved in the breakdown of propeptides of storage proteins in protein-storage vacuoles (By similarity). Possesses aspartic protease activity in vitro |
m01oak03575jC | 32 | 29 | 1 | 88% | Cryptochrome-1 | CRY1 | Photoreceptor that mediates primarily blue light inhibition of hypocotyl elongation and photoperiodic control of floral initiation, and regulates other light responses, including circadian rhythms, tropic growth, stomata opening, guard cell development, root development, bacterial and viral pathogen responses, abiotic stress responses, cell cycles, programmed cell death, apical dominance, fruit and ovule development, seed dormancy, and magnetoreception |
m01oak00924cC | 53 | 34 | 1 | 84% | Auxin-responsive protein IAA8 | IAA8 | Aux/IAA proteins are short-lived transcriptional factors that function as repressors of early auxin response genes at low auxin concentrations. Repression is thought to result from the interaction with auxin response factors (ARFs), proteins that bind to the auxin-responsive promoter element (AuxRE). Formation of heterodimers with ARF proteins may alter their ability to modulate early auxin response genes expression |
m01oak01539cC | 15 | 10 | 4 | 84% | Translation initiation factor SUI1 family protein (TAIR database) | AT5G11900 | none |
