the immune system to defend from toxic aflatoxins. Its functions include improving memory and prevent the liver and kidney from taking damage from drug overdoses. In China, the dietary supplement with GSPE show great health benefits to both people and animals. Also, it has the ability to inhibit the effect of food intake, so it can help with weight control. Economically important food plants Plants that humans use for food are of high economic importance. Research into food plants generally involves increasing the size of the edible plant organ in question, or increasing the areas where the plant can be grown, and less frequently, finding new crop species. Results of such research are often published in the journal Economic Botany. The New Zealand-based Plant & Food Research publishes its own journal on cultivar development and sustainable production systems for high quality produce, and the design and development of new and novel functional foods. Rice Rice was first domesticated approximately 5,000 years ago, in Southeast Asia. Rice and American wild rice are believed to have been domesticated separately. Rice variants have been adapted to the tropics where they provide a grain staple, but rice can be grown almost anywhere. The introduction of dwarf rice variants made several rice-producing countries self-sufficient. Rice is suited to countries with high rainfall. People consume a lot of rice everyday worldwide. If the rice producers can improve the quality and quantity of their rice crops, it would be very profitable for the farmers. The timing of adding nutrition or fertilizer to the rice crop is important since the nutrition will attract pests, which would then damage the plants. So, the farmers check the color of the rice plant's leaves as the indicator for when they need to apply nitrogen fertilizer. Then, farmers can manage their farms more successfully. Another recent study about the rice husk is also valuable. The rice husk extract ETOAC can be a good antioxidant. It can turn the unused part of the rice plant into something valuable and protects our environment. Teosinte The teosintes are grasses of the genus Zea. Native Americans bred and selected teosinte for the traits we see in corn today (large ears, multiple rows of kernels). The first ears of maize were very short, with only 8 rows of kernels. Modern corn is the result of several thousand generations of selective breeding. Modern corn is incapable of reproducing
