Rhizopogon roseolus excretes the transfer RNA component, N-[9-(beta-d-ribofuranosyl-9H) purin-6-ylcarbamoyl]threonine (Ado-CO-thr) into the culture medium. This compound was proposed to be the archetype of ureidopurines exhibiting cytokinin activity. The amount of Ado-CO-thr isolated from the medium is about one-twentieth the amount of ribosylzeatin that can be isolated.
玫瑰红根须腹菌会将转运RNA成分N-[9-(β-D-呋喃核糖基-9H)嘌呤-6-基氨基甲酰基]苏氨酸(Ado-CO-thr)分泌到培养基中。该化合物被认为是具有细胞分裂素活性的脲基嘌呤的原型。从培养基中分离出的Ado-CO-thr的量约为可分离出的核糖基玉米素量的二十分之一。
