Drought genes in hybrid PR-24 lacking variants found in Q. engelmannii, as candidates for genes involved in local adaptation to warm or dry habitats

Gene (transcriptome contig)	Biallelic variants	engelmannii-fixed variants	Variants with no engelmannii allele in hybrid PR-24	% Identity to Arabidopsis protein	Uniprot Protein Description	Gene	Uniprot Function Description
m01oak09012cC	61	47	6	80%	4-coumarate--CoA ligase-like 7	4CLL7	Contributes to jasmonic acid biosynthesis by initiating the beta-oxidative chain shortening of its precursors.
m01oak03358CC	56	24	5	81%	4-coumarate--CoA ligase 1	4CL1	Produces CoA thioesters of a variety of hydroxy- and methoxy-substituted cinnamic acids, which are used to synthesize several phenylpropanoid-derived compounds, including anthocyanins, flavonoids, isoflavonoids, coumarins, lignin, suberin and wall-bound phenolics
m01oak00399CT	12	9	1	63%	Glutathione S-transferase F7	GSTF7	May be involved in the conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles and have a detoxification role against certain herbicides (also possible response to salt stress)
