Relative fitness in laboratory mice of drug resistant and drug-sensitive field isolates of Trypanosoma congolense por Coleman, P.G., Eisler, M.C., McDermott, John J., Murphy, N.B., Majiwa, Phelix A.O., Peregrine, A.S.

“…Trypanocidal drug resistance is a growing problem across much of sub-Saharan Africa and increasingly recognised as a major threat to livestock production. It is therefore of pressing importance to identify effective ways of slowing the spread of resistance to available trypanocidal drugs, especially as it is unlikely that new chemotherapeutic products will become available in the foreseeable future. …”

Development of disease-resistant rice by optimized expression of WRKY45 por Goto, Shingo, Sasakura-Shimoda, Fuyuko, Suetsugu, Mai, Gómez Selvaraj, Michael, Hayashi, Nagao, Yamazaki, Muneo, Ishitani, Manabu, Shimono, Masaki, Sugano, Shoji, Matsushita, Akane, Tanabata, Takanari, Takatsuji, Hiroshi

“…The agronomic traits of two lines expressing WRKY45 driven by the OsUbi7 promoter (POsUbi7 lines) were nearly comparable to those of untransformed rice, and both lines were pathogen resistant. Interestingly, excessive WRKY45 expression rendered rice plants sensitive to low temperature and salinity, and stress sensitivity was correlated with the induction of defence genes by these stresses. …”
