Fig. 3From: Improved cold tolerance in switchgrass by a novel CCCH-type zinc finger transcription factor gene, PvC3H72, associated with ICE1–CBF–COR regulon and ABA-responsive genesqRT-PCR analysis on relative expression of PvC3H72 in response to different abiotic treatments. Four-week-old seedlings were treated with 100 µM ABA, 20% PEG6000 (w/v), NaCl (250 mM) or cold (4 °C). Letters above bars indicate significant difference at P < 0.05 (n = 3)Back to article page
