1 Null ics1 mutants still accumulate some SA, suggesting the existence of an enzymatic activity redundant with ICS1 or of an alternative ICS-independent SA biosynthetic route. Salicylic Acid ADC synthase superfamily protein Arabidopsis thaliana
2 Null ics1 mutants still accumulate some SA, suggesting the existence of an enzymatic activity redundant with ICS1 or of an alternative ICS-independent SA biosynthetic route. Salicylic Acid ADC synthase superfamily protein Arabidopsis thaliana
3 Comparison of SA accumulation in the ics1, ics2, and ics1 ics2 mutants indicates that ICS2 participates in the synthesis of SA, but in limited amounts that become clearly detectable only when ICS1 is lacking. Salicylic Acid ADC synthase superfamily protein Arabidopsis thaliana
4 Furthermore, detection of SA in the double ics1 ics2 double mutant that is completely devoid of phylloquinone provides genetic evidence of the existence of an ICS-independent SA biosynthetic pathway in Arabidopsis. Salicylic Acid ADC synthase superfamily protein Arabidopsis thaliana
