  12. Development of disease-resistant rice by optimized expression of WRKY45 by 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

    Published 2015
    “…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. …”

  15. Vulnerability to climate change of cocoa in West Africa: patterns, opportunities and limits to adaptation by Schroth, Götz, Läderach, Peter R.D., Martínez Valle, Armando Isaac, Bunn, Christian, Jassogne, Laurence T.P.

    Published 2016
    “…We find that: 1) contrary to expectation, maximum dry season temperatures are projected to become as or more limiting for cocoa as dry season water availability; 2) to reduce the vulnerability of cocoa to excessive dry season temperatures, the systematic use of adaptation strategies like shade trees in cocoa farms will be necessary, in reversal of the current trend of shade reduction; 3) there is a strong differentiation of climate vulnerability within the cocoa belt, with the most vulnerable areas near the forest-savanna transition in Nigeria and eastern Côte d'Ivoire, and the least vulnerable areas in the southern parts of Cameroon, Ghana, Côte d'Ivoire and Liberia; 4) this spatial differentiation of climate vulnerability may lead to future shifts in cocoa production within the region, with the opportunity of partially compensating losses and gains, but also the risk of local production expansion leading to new deforestation. …”

    Published 2016
    “…The mean aflatoxin was 2.94 µg/kg and all samples (n=440) were within the East African Community (EAC) standard of 10 µg/kg for total aflatoxin, but the mean fumonisin was 5.15 mg/kg, more than double the EAC standard of 2 mg/kg, and 35% of samples exceeded this standard. Maize samples obtained from farmers in the village in the mid altitude, dry zone had significantly higher mean aflatoxin (3.32 µg/kg) and significantly lower mean fumonisin (3.17 mg/kg) than maize from the other two villages (in the high and mid altitude, high rainfall zones). …”
