cereal cyst nematode (CCN), Heterodera avenae (Wollenweber, 1924)
is one of the important parasites that attack wheat and barley crops
in the cereal growing areas of the world. Most damaging species on
cereals has been reported to occur in Australia, Canada, Israel, South
Africa, Japan, north America, Estonia and most of the European countries.
Since its first report in India, it has become an endemic
problem in wheat growing belts extending from northern hill regions to central India. Cyst nematodes are
obligate sedentary endoparasites that reproduce by obligatory amphimixis.
They have a synchronized life cycle with their host. It can survive
in the soil for long periods, making it a difficult pest to manage.
Pre-parasitic Juvenile (J2) and parasitic feeding female (FF) are the
most important stages to identify effectors of parasitism of this parasite.
The H. avenae Transcriptome Database (HATDB) has been developed
with the view to provide most comprehensive information about the H.
avenae. The most relevant part of the genome. The HATDB
is freely available resource, which may provides user a
portal to search, browse and query the data to assist the research on
H. avenae and other plant parasitic nematodes.
