Assuring adequate tenure rights to land is an important step in improving food security for millions of people in developing countries, but safeguarding tenure isn't so straightforward when it comes to the way land is used by mobile pastoralist communities.

Researchers from the Natural History Museum of Denmark published a study of a 5,310-year-old maize cob from the Tehuacan Valley of Mexico, providing new insights into the early stages of maize domestication. In the gene-by-gene analysis, the ancient sample shows many key genes had already been modified through human selection, including the lack of a hard seed coat and changes in flowering time.

The U.S. Court of Appeals released their 30-page ruling that counties cannot regulate pesticides or genetically engineered crops. This is following the partial ban on planting GE crops in Hawaii Country, which is now invalid after the ruling. The appellate court said that the ban violated state and federal law. They also found that the pesticide laws of Hawaii are comprehensive enough for safeguard, and that the Legislature intended it to be "uniform and exclusive of additional, local rules."

An international team of scientists successfully boosted the productivity of plants by altering mechanisms involved in photosynthesis. The result of their proof-of-concept study is published in the journal Science. The scientists targeted three genes in tobacco plants which are involved in sunshield. These genes are responsible in protecting the plant from bright sunlight by converting photons into harmless heat

In a study on two groups of parasites, the team detected differences in DNA sequences that could be attributed to the composition of their food. The results are published in the journal Genome Biology. Study co-author Dr Steven Kelly, from Oxford's Department of Plant Sciences, said: 'Organisms construct their DNA using building blocks they get from food. Our hypothesis was that the composition of this food could alter an organism's DNA.

Scientists from the Chinese Academy of Agricultural Sciences reported the first successful generation of marker-free transgenic hexaploid wheat using commercial Chinese wheat varieties. Transgenic wheat plants were generated using Agrobacterium-mediated transformation, and were confirmed using Quickstix strips, histochemical staining
