The mechanism of resistance of Castanea crenata to Phytophthora cinnamomi may derive from its expression of the Cast_Gnk2-like gene.

[5] Castanea crenata is a small to medium-sized deciduous tree growing to 10–15 m (30–50 ft) tall.

They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3–7 brownish nuts that are shed during October.

Castanea crenata is an important tree in Japan and Korea for its heavy production of sweet, edible nuts.

Examples of European × Japanese hybrid cultivars[6] are: C. crenata produces more biomass in its stems when the nuts are smaller and planted deeper.
