Transgenic plants of cassava (Manihot esculenta) resistant to the herbicide Basta were obtained through Agrobacterium-mediated transformation. The plants also expressed the uidA gene and two were positive for PCR- and/or Southern-based detection of the nptII gene. Somatic-embryo-derived cotyledon...

A major constraint for incorporating new traits into cassava using biotechnology is the limited list of known/tested promoters that encourage the expression of transgenes in the cassava’s starchy roots. Based on a previous report on the glutamic-acid-rich protein Pt2L4, indicating a preferential ...

Breeding goals of yield increases, root quality improvement, and disease resistance in cassava are considerably slowed down by biological characteristics of the crop, which includes a long growth cycle, a heterozygous genetic background and a poor knowledge of the organization of crop diversity. ...
