Crop domestications are long-term selection experiments that have greatly advanced human civilization. The
domestication of cultivated rice (Oryza sativa L.) ranks as one of the most important developments in history.
However, its origins and domestication processes are controversial and have long been debated. Here we generate
genome sequences from 446 geographically diverse accessions of the wild rice species Oryza rufipogon, the
immediate ancestral progenitor of cultivated rice, and from 1,083 cultivated indica and japonica varieties to construct

The present study on the plant nematodes associated with Bt cotton crop growth in northern Karnataka, India covered several aspects like a nematode random survey in Bt cotton-growing areas of the state, nematode community analysis, pathogenicity and biology of a dominant nematode and reaction of Bt cotton cultivars and hybrids to that nematode. A random survey undertaken in the Bt cotton-growing districts of northern Karnataka for the associated nematodes in
