The silencing of IFS had no effect on nodulation using S. meliloti even though isoflavonoids were the major flavonoids in M. truncatula roots. IFS silencing had a more dramatic effect on the total flavonoid content in the roots than did FNS and CHR silencing. Yet, IFSi roots produced as many nodules as the vector control roots. This suggests that isoflavonoids are not likely to play a critical role during nodulation in M. truncatula.
