| Groundbreaking DNA tests could trap deer poachers Posted: 09 Sep 2011 11:16 AM PDT Human DNA found on deer remains could help to track down poachers. Identifying deer poachers can be problematic, as the crimes are often committed in remote areas and are not discovered until some time after the event.  |
| How can high-quality seed be reproduced? Posted: 09 Sep 2011 08:16 AM PDT Some wild plants show the particular characteristic of apomixis. This is a process adopted for producing seeds without fertilization or genetic recombination, giving rise to exact copies of the mother plant. This is an unusual method of reproduction and researchers are seeking to apply it to agriculturally useful plant species such as wheat or maize. Such a revolution would spare farmers the need to buy seed every year, particularly in the countries of the South.  |
| Diamondback moth host-parasite interaction unraveled: Important implications for global pest-control Posted: 09 Sep 2011 04:49 AM PDT The diamondback moth, Plutella xylostella, is one of the world's most destructive crop pests. It has developed resistance to many chemical and biological pesticides, and the estimated global cost of controlling this insect is approximately one billion dollars US annually. Researchers from have now identified the genes expressed when the diamondback moth is attacked by a parasitic wasp, which could have significant implications for controlling this notorious pest.  |
