Three late blight resistance (R) genes from wild potato species were transferred as a stack into the farmer-preferred varieties ‘Tigoni’ and ‘Shangi’. Transgenic events were tested by detached-leaf assays (DLA) and whole-plant assays (WPA) with isolates of Phytophthora infestans using 20,000 spor...

Extreme resistance to late blight disease by transferring 3 R genes from wild relatives into African farmer-preferred potato varieties.
During the last decade, genomics research has generated new insights into potato genetics and made possible new strategies for varietal improvement. The most commonly grown and eaten potato is an autotetraploid, highly heterozygote crop suffering from rapid inbreeding depression. The genetic impr...

Resistencia a Phytophthora infestans linaje clonal EC-1 en Solanum tuberosum mediante la introduccion del gen RB
Considered responsible for one million deaths in Ireland and widespread famine in the European continent during the 1840s, late blight, caused by Phytophthora infestans, remains the most devastating disease of potato (Solanum tuberosum L.) with about 15%–30% annual yield loss in sub‐Saharan Afric...

Stacking three late blight resistance genes from wild species directly into African highland potato varieties confers complete field resistance to local blight races
The Avr avirulence gene of Phytophthora infestans and R gene of the potato are the genetic components of the gene-for-gene interaction resulting in host plant resistance. This effector-triggered immunity has been recently exploited to generate extreme resistance to late blight in potato by geneti...

Rpi-blb2 gene from Solanum bulbocastanum confers extreme resistance to late blight disease in potato
Phytophthora infestans remains the most devastating potato pathogen worldwide. In developing countries it causes annual losses of up to 2.75 billion USD, excluding the cost of pesticides. Host plant resistance mediated by single R genes has been rapidly overcome by P. infestans on many occasions....

Development of late blight resistant potato biotech varieties for Sub-Saharan Africa.
Average potato yields in sub-Saharan Africa are four times lower than those in industrialized nations, mostly due to the effects of diseases, particularly late blight. This research demonstrates that the transfer from wild potato relatives of three resistance-conferring genes into a cultivated po...

Bioengineered potato: Resistance to late blight disease and higher crop yields. Research Brief 01.
The cultivated potato, Solanum tuberosum is affected by a variety of diseases with late blight (LB) caused by Phytophthora infestans being the most severe. The disease is mostly controlled by the application of large quantities of fungicides, which represent a financial burden on farmers indevelo...
