Taphrina padi Taphrina padi Taphrina padi is a fungal plant pathogen that induces the form of pocket plum gall that occurs on Bird Cherry ("Prunus padus"). The gall is a chemically induced distortion of the fruits, which are swollen, hollow, curved and greatly elongated, without a seed or stone, but retaining the style. The twigs on infected plants may also be deformed with small strap-shaped leaves. "Taphrina padi", a 'tongue fungus', produces a distinctive, elongated, tongue-like growth on Bird Cherry, similar to other closely related species such as "Taphrina alni" on Alder ("Alnus glutinosa") and "Taphrina pruni" on Blackthorn ("Prunus spinosa"). The
Prunus kansuensis locally. The fruit is eaten by the endangered golden snubnosed monkeys ("Rhinopithecus roxellana"). Prunus kansuensis Prunus kansuensis (), sometimes called the Chinese bush peach, is a putative species of peach native to China. It is found in Gansu, Guizhou, Hubei, Qinghai, Shaanxi and Sichuan provinces. It is a shrub or tree tall, preferring to grow at above sea level. A genetic and morphological study has shown that it is conspecific with "Prunus persica", the cultivated peach. "P.kansuensis" is being investigated as a source for rootstocks and for crop improvement due to its resistance to multiple diseases, to drought, and to
