Research Abstract

The parasitic weeds Striga spp. are among the world most devastating pests. Striga infests major crops, such as maize and sorghum, and causes drastic yield losses. However, resistance mechanisms against Striga have not been well understood. Lotus japonicus showed strong resistance to Striga infection. I screened mutagenized Lotus japonicus M2 generation to find mutants which show altered-resistance to Striga infection.
