Figure 2.
(A) Whole‐mount in situ hybridization of Hirschmanniella oryzae showing the spatial expression pattern of β‐mannanase (a), xylanase (GHF30) (b), thaumatin‐like protein (c) and chorismate mutase (d). The negative control (e) showed no signal. Arrows indicate the stained region of the pharyngeal region (c) or pharyngeal glands (a, b, d). Magnification, 128×. (B) Anatomy of the pharyngeal region of H. oryzae. Contrary to some other plant‐parasitic nematodes (e.g. Heterodera sp.), the pharyngeal glands overlap the intestine.
