Fig. 7From: The interplay between miR156/SPL13 and DFR/WD40–1 regulate drought tolerance in alfalfaWD40–1 regulates transcript levels of genes in the phenylpropanoid pathway and photosystem during drought stress. a Transcript levels of PHENYLALANINE AMMONIA-LYASE, PAL; b DIHYDROFLAVONOL-4-REDUCTASE, DFR; c FLAVONOID GLUCOSYLTRANSFERASE2, FGT2; d DEHYDRATION RESPONSIVE RD-22-LIKE, DRR; (e) PHOTOSYSTEM I p700 CHLOROPHYLL A APOPROTEIN APS I, PSI; f PHOTOSYSTEM II Q(b), PSII. Transcript levels are shown relative to EV after being normalized to acetyl-CoA carboxylase, ACC1, and ACTIN housekeeping. Values are means ± SE, n = 4 individual plants, ANOVA p values are provided in Additional file 2: Table S5.9; g schematic representation of miR156-based alfalfa drought resilience model system. Solid line represents an experimentally confirmed mechanism while broken lines are hypothesized functions. Arrow heads indicate positive regulation while line heads indicate negative regulation. Significant difference in Post hoc Tukey multiple comparisons test is indicated with different lettersBack to article page
