Two additional FMOGS-OX enzymes; FMOGS-OX6 and FMOGS-OX7 encoded by At1g12130 and At1g12160 respectively. The overexpression of both FMOGS-OX6 and FMOGS-OX7 decreased the ratio of methylthioalkyl GSLs to the sum of methylthioalkyl and methylsulfinylalkyl GSLs suggesting that the introduction of the two genes converted methylthioalkyl GSLs into methylsulfinylalkyl GSLs (Kong et al. 2016)
