The genetic diversity of the 34 populations of wild rice Oryza meyeriana Baill distributed in Yunnan Province, China was analyzed using 13 inter-simple sequence repeat (ISSR) markers.

A total of 168 bands were amplified, of which 135 polymorphic bands were discovered and the percentage of polymorphic bands (PPB) was 80.36%. A genetic diversity was revealed as Nei’s gene diversity(H)=0.2666 and Shannon information index(η)=0.4028 at population level.

The 34 populations were divided into different groups based on administrative regions, latitude and longitudes, river areas, altitudes of their origins, and their indexes such as Na (number of alleles), Ne (effective number of alleles), H, I and PPB were calculated.

Richer genetic diversity was found in the wild rice populations distributed in Simao Prefecture than that in Lingcang Prefecture or Xishuangbanna Prefecture whereas the least genetic diversity was in Baoshan Prefecture or Dehong Prefecture.

Rich genetic diversity was also discovered in the wild rice populations originated from higher than 710 m altitude around the middle and lower reaches of the Lancang River belonging to the Pacific Ocean drainage system.

The 34 populations could be classified into two groups, one group covered the wild rice distributing in Simao Prefecture only while the other group covered ones in Lingcang, Xishuangbanna and Oehong Prefectures. The issue on how to effectively conserve the wild rice germplasm was discussed.

Based upon pictures from the time and stories told by residents who were there, the capital became a lake in a matter of days. …

Xinhua - China
XINING, Sept. 6 (Xinhua) — China launched an expedition on Saturday that aims to find the sources of the country’s three major rivers.

The 40-member team has survey, remote sensing, glacier and geological experts. They will spend about 45 days and cover 8,000 km seeking the sources of the Yangtze River — the country’s longest — the Yellow River and the Lancang River, all of which originate in plateau in the southern part of Qinghai Province.

“It is an important scientific task,” said Sun Shu, a Chinese Academy of Sciences (CAS) academician.

Sun said there have been previous expeditions dating back to ancient times, but none found the exact sources.

Liu Shaochuang, a team member and CAS remote sensing scientist, said the findings of the expedition would be submitted to the government for the establishment of national geographic data.
