1.1.1.284	malfunction	suppression of S-nitrosoglutathione reductase (GSNOR) promotes axillary buds outgrowth via inhibiting the expression of flavin monooxygenase (FZY) in both apical and axillary buds. Meanwhile, AUX1 and PIN1 are downregulated in apical buds but upregulated in axillary buds in GSNOR-suppressed plants. Thus, reduced indoleacetic acid (IAA) accumulation is shown in both apical buds and axillary buds of GSNOR-suppressed plants. A decreased ratio of auxin:cytokinin is observed in axillary buds of GSNOR-suppressed plants, leading to buds dormancy breaking. GSNOR plays a positive role in regulating FZY expression and IAA level in apical buds. Notably, levels of IAA in axillary buds show similar patterns with that in apical buds, but an inhibition of FZY transcript in axillary buds is observed by both overexpression and suppression of GSNOR. Silencing FZY results in auxin biosynthesis inhibition and axillary buds outgrowth. Inhibitory effects on FZY expression and IAA accumulation lead to highly branched phenotype in tomato plants	Solanum lycopersicum
1.1.1.284	physiological function	S-nitrosoglutathione reductase (GSNOR) negatively regulates NO homeostasis. GSNOR-mediated changes of NO and auxin affect cytokinin biosynthesis, transport, and signaling. suppression of GSNOR decreased the transcripts of AUX1 and PIN1 in apical buds, but increased the transcripts of AUX1 and PIN1 in axillary buds. GSNOR-controlled NO plays important roles in controlling axillary buds outgrowth via altering the homeostasis and signaling of auxin and cytokinin in tomato plants	Solanum lycopersicum
