Grain yields of resistant cultivars are often lower. Thus, these cultivars are currently less attractive for conventional agriculture, but interesting options for organic producers. 

Rice is the most important staple food crop in the world and has also emerged as the model cereal species (it is the only terrestrial plant other than Arabidopsis thaliana to benefit from a completed genome sequence, and extensive EST resources are also available). Rice has a lower annual grain yield than maize (6600 kg ha-1) and the grain has a lower protein content (8%), but like maize it is easy to transform and manipulate in the laboratory, a range of useful expression cassettes have been devel-...
