Abstract:

Reniform nematode is a parasitic roundworm that infects over 300 different plant species in the tropical, subtropical, and warm temperate regions of the world. During infection, the female nematode penetrates a host root and converts part of the tissue into a feeding site. The objective of our study was to identify the specific plant genes involved in feeding site formation. We sequenced mRNA from infected and uninfected roots in a split-root system for several soybean plants across a 12-day time course. Through gene-expression comparison, we identified many transcription factor genes that seem to play an important role in nematode parasitism. These genes will be the target of future functional analysis study.
