The root exudates of alfalfa (Medicago sativa) and mungbean (Vigna radiata) induced the Tsr (thick and short roots) factor production in Rhizobium meliloti. The factor caused a 30-40% reduction of root length in alfalfa seedlings. Pea root exudate had no Tsr induction activity. The flavonoid naringenin could replace the roots in inducing Tsr production. Naringenin-induced Tsr factor caused 70% shortening of main roots. The Tsr inducing property of naringenin was specific since quercetin and syringaldehyde had no such effect.
紫花苜蓿（Medicago sativa）和绿豆（Vigna radiata）的根系分泌物可诱导苜蓿根瘤菌产生Tsr（根粗短）因子。该因子可使苜蓿幼苗的根长减少30%-40%。豌豆根系分泌物没有Tsr诱导活性。类黄酮柚皮素可替代根系诱导Tsr产生。柚皮素诱导产生的Tsr因子可使主根缩短70%。柚皮素的Tsr诱导特性具有特异性，因为槲皮素和丁香醛没有这种作用。
