Soybean roots infected by M. incognita at different time points. (a) galls formed on soybean roots at 12 dai; red arrows point to the galls; (b) giant cells and M. incognita in soybean roots at 12 dai (taken by LCM; bar 500 μm); red arrows point to giant cells; white arrowheads points to the nematode; (c) galls formed on soybean roots at 10 wai; red arrows point to the galls; (d) giant cells and M. incognita in soybean roots at 10 wai (taken by LCM; bar 500 μm); red arrows point to giant cells; white arrowhead points to the nematode
