The importance of cassava as the fourth largest source of calories in the world requires that contributions of biotechnology to improving this crop, advances and current challenges, be periodically reviewed. Plant biotechnology offers a wide range of opportunities that can help cassava become a b...

Cassava (Manihot esculenta Crantz) is a tough and productive survival crop of smallholder farmers in the tropics. It is often grown where other crops fail. Research can make important contribution to food security and economic development in cassava-growing areas. This can be enhanced through in-...

TMS60444 (MNig11) with A. tumefaciens carrying a cry1Ab gene for insect resistance]Transformation of cassava cv. TMS60444 (MNig11) with A. tumefaciens carrying a cry1Ab gene for insect resistance

To help solve breeding problems in cassava that have long eluded conventional strategies, a routine transformation protocol is esential. The agropine-mannopine nondisarmed strain of Agrobacterium tumefaciens (CIAT 1182) was selected and used with the binary vector pGV1040. This vector contains th...


Sarria, RABalcázar, NDestéfano Beltrán, L.J.C.Roca, William M.[Progress in Agrobacterium-mediated transformation of cassava (Manihot esculenta Crantz)]Progress in Agrobacterium-mediated transformation of cassava (Manihot esculenta Crantz)

Our strategy for Aqrobacterium-mediated cassava transformation involves the utilization of cotyledonary leaves from somatic embryos and infection with both wild and disarmed strains. Virulence tests for wild Aqrobacterium strains as well as regeneration protocols have been developed; the plasmid ...
