The main reason for the 1KP project is to better understand the genes from over 1,000 plant species.
What Is the 1,000 plants (1KP) project?
This refers to the project that was made with the initiative of making a sequence and analysis of over 1,100 different plant species by plant biologists.
Hence, we can see that your question is unclear as the 1KP project has to do with the sequencing and analysis of plant life, so the question of why "4 of 1k plants are not working for Americans" is unclear, hence, the general overview of the 1KP project.
