BRS Celeste: nova cultivar de soja para o sistema de produção de grãos no cerrado

Maintenance or improvement of technology to soybean cultivation is necessary to reach economical productivity in the Brazilian Savannah, where it has shown to be superior to that obtained in the South of Brazil. New cultivars are among the contributions of research to high crop performance and yield stability. The soybean cv. BRS Celeste is an alternative to suit growers demand. It belongs to the same maturity group of cv. BR/EMGOPA 314 (Garca Branca), although it has higher yielding and shows resistance to the main diseases, especially stem canker (Diaporthe phaseolorum f. sp. meridionalis).

Radiation as a tool to remove selective marker genes from transgenic soybean plants

The present study evaluated the use of γ-radiation to physically remove selective marker genes previously introduced into the soybean genome. Homozygous seeds from a transgenic soybean line carrying the gus and ahas transgenes were irradiated with γ-rays. Six plants presenting a deleted gus gene were analyzed by Southern blot to confirm removal of both ahas and gus genes. Line 1A presented an absence of the gus gene cassette and presence of the ahas gene cassette.
