Fig. 1From: Comparative transcriptomics of Gymnosporangium spp. teliospores reveals a conserved genetic program at this specific stage of the rust fungal life cycleIllustration of rust disease symptoms caused by three Gymnosporangium species (G. asiaticum, G. yamadae and G. japonicum) on different organs of juniper (J. chinensis L.). Conical telia of G. asiaticum are folicolous and sometimes aggregated on witches’ broom; tongue-shaped telia of G. yamadae are formed on juniper gall, causing twigs dieback; whereas edge-shaped telia of G. japonicum are formed on trunk, causing tree shape malformation and gradually cracked trunk. Telia and teliospores can absorb water and become gelatinous with bright-yellow colour after a heavy rainBack to article page
