Research highlight
Nematodes are small worm-like animals found in many environments in the
world. Among them, root-knot nematodes (Meloidogyne incognita, Fig. 1) are economically important pathogens that affects many regions
of the world, including Kyushu, Japan. These nematodes are plant parasites
that infect roots to absorb nutrients from the plant hosts, causing serious
agricultural damages (Fig. 2).
It is believed that plant-pathogenic nematodes detect chemicals secreted
from plants to find hosts. We are interested in what plant-secreted chemicals
affect nematode behaviors, and how nematodes perceive and respond to these
chemicals. For example, we have found that nematodes are attracted to certain
compounds secreted from the seeds (Fig. 3). Through our research, we hope
to develop new strategies to protect crop plants from pathogens.
