Fig. 4From: Hydrogen cyanamide induces grape bud endodormancy release through carbohydrate metabolism and plant hormone signalingEffect of HC on IAA signals transduction. Bars indicate ± SEM of three biological replicates and different letters indicate significant difference. Different letters in the figure indicate significant difference (P < 0.05). Red color: up-regulation; Green color: down-regulation. a Concentration of IAA in two different treatments. b Transcripts related to IAA signal transduction analyzed by qRT-PCR. c Different factors in IAA signal transduction pathway affected by HC treatment. ARF, auxin response factors; AUX1, auxin / indoleacetic acids proteins; GH3, gretchen hagen 3; SAUR, small auxin-up RNABack to article page
