----------------------------------------Creating a better breed of rice Cross-breeding has long been used to improve agricultural crops, but when the two major varieties of Asian rice are crossed, the result is often a much sturdier, but sterile hybrid. Qifa Zhang and colleagues discovered that a previously unknown gene, which they named S5, is responsible for the sterility when crossing the main rice varietal groups, indica and japonica. Two subtly different forms of the S5 gene, one each in indica and japonica, produce healthy and fertile rice by themselves, but when the genes from the two varieties are combined through breeding, the offspring are highly sterile. The researchers also examined a third varietal group of "wide-compatibility" rice, which revealed that a large chunk missing from its S5 gene is the reason that wide-compatibility varieties make fertile hybrids when bred with the other two varieties. They sampled 16 more Asian rice varieties and confirmed S5's role, which offered the first direct causal evidence of why most indica-japonca hybrid rice is sterile. The authors suggest that their results can help improve rice plant breeding and lead to better rice crops worldwide. ARTICLE #08-04761: "A triallelic system of S5 is a major regulator of the reproductive barrier and compatibility of indica-japonica hybrids in rice," by Jiongjiong Chen, Jihua Ding, Yidan Ouyang, Hongyi Du, Jiangyi Yang, Ke Cheng, Jie Zhao, Shuqing Qiu, Xuelian Zhang, Jialing Yao, et al.

if we're lucky, they will also put a little something in that rice to make us high

News some will have missed, including me:
----------------------------------------Nutritious Rice Project on IBM World Community Grid Yields Promising Results http://www.pressreleasepoint.com/node/117548 10 Million Computations in Nine Months ARMONK, NY - 10 Dec 2008:The landmark project between IBM (NYSE:IBM) and the University of Washington to develop new strains of rice that could produce crops with larger and more nutritious yields is now set to analyze data on the genes -- three months ahead of schedule. The research will focus on analyzing data that has been prioritized as promising by both the University of Washington in Seattle and the International Rice Research Institute in the Philippines. Researchers will now begin to analyze the results while data continues to be collected on the rest of the proteins, according to IBM. "While headlines about rice shortages have declined, the problem is still very real," said Stanley S. Litow, IBM Vice President of Corporate Citizenship and Corporate Affairs. "More than 400,000 volunteers have already contributed 9,000 years of computer time to this project, and individual computers have processed more than 10 million transactions." "Improving strains of rice to yield larger, more resilient, and nutritionally-optimized harvests will positively impact the lives of billions of people. This is a first-of-a-kind solution that demonstrates how a smart application of technology can offer a game-changing solution that can potentially create a greater change in society and how it deals with food issues." The project is studying the structures of the proteins that make up the building blocks of rice. This will help identify the function of those proteins and enable researchers to identify which proteins could help produce more rice grains, ward off pests, resist disease or hold more nutrients. In the end, this project will create the largest and most comprehensive map of rice proteins and their related functions, helping rice researchers pinpoint which plants should be selected for cross-breeding to cultivate better crops. "The community response to this project has been phenomenal. IBM's World Community Grid exceeds our expectations of computational power and makes scientific dreams a reality," said Michal Guerquin, project lead at the University of Washington. IBM'sWorld Community Gridis a virtual supercomputer created by individuals who donate their unused computer time to tackle complex calculations to accelerate scientific research. World Community Grid is collecting data for 30,000 to 60,000 different protein structures. Anyone with a computer and Internet access can be a part of the solution. To donate unused computer time, individuals register onwww.worldcommunitygrid.organd install a free, small, secure software program onto their computers. When computers are idle, data is requested from World Community Grid's server. These computers then perform the computations, and send the results back to the server, prompting it for a new piece of work. A screen saver will tell individuals when their computers are being used. World Community Grid, the largest public humanitarian grid in existence, has 430,000-plus members who represent more than 200 countries and links to more than one million computers.

This is misleading information, halfcard, if you present it without any comment. Again, the "Nutritious Rice for the World" project we run here is not for creating genetically modified rice, it is to help traditional rice farmers to be more efficient when using traditional crossbreeding. |

Very pertinant article on rice. With out proper nutrition it is difficult to treat any disease. Amazing how "solar" power creates so much diversity in plants. Also the article noted above concerning sterility is suprising as I would figure that suprises like this new gene S5 would have been discovered/identified long ago in such an important food source.

The first U.S.-bred Jasmine-type aromatic rice variety named Jazzman has been developed at the Louisiana State University (LSU) Ag- Center’s Rice Research Station and released in 2009.
