The only indole glucosinolates detected in the A. thaliana seeds were indol-3-ylmethyl glucosinolate (I3M) and trace amounts of its 4-hydroxyl derivative; which in total comprised only 2% of the seed glucosinolate content. In the leaves proportion of aliphatic glucosinolates declined with age resulting in the predominance of indole glucosinolates; mostly indol-3-ylmethyl glucosinolate (I3M) and its 1-methoxyl derivative (1MOI3M); by the time of senescence (Brown et al. 2003)
