This study suggests that in the host surface teliospore may also produce a short germ tube, continue to produce dual-core mycelium which germinated to form urediniospores, then urediniospores germinate and infect host plants repeatedly.

本研究认为锈菌冬孢子可能也会在寄主表面萌发产生一个生长的短芽管，继续萌发产生双核菌丝体形成夏孢子，夏孢子萌发继续反复侵染寄主植物。
