Adding value to field-based agronomic research through climate risk assessment: a case study of maize production in Kitale, Kenya por Dixit PN, Cooper, Peter J.M., Dimes, John P., Rao, K.P.C.

“…Similarly, rates of return to weed control and to planting at contrasting populations were also affected by seasonal variations in weather, but were always so high as to not constitute a risk for small-scale farmers. An analysis investigating the relative importance of temperature, radiation and water availability in contributing to weather-induced risk at different maize growth stages corresponded well with crop physiological studies reported in the literature.…”

RNAi-mediated resistance to diverse isolates belonging to two virus species involved in Cassava brown streak disease por Patil, B.L., Ogwok, E., Wagaba, Henry, Mohammed, I.U., Yadav, J.S., Bagewadi, B., Taylor, Nigel J., Kreuze, Jan F., Maruthi, M.N., Alicai, Titus, Fauquet, Claude M.

“…Three RNAi constructs targeting the highland species were generated, consisting of the full‐length (FL; 894 nucleotides), 397‐nucleotide N‐terminal and 491‐nucleotide C‐terminal portions of the coat protein (CP) gene of a Ugandan isolate of CBSUV (CBSUV‐[UG:Nam:04]), and expressed constitutively in Nicotiana benthamiana. After challenge with CBSUV‐[UG:Nam:04], plants homozygous for FL‐CP showed the highest resistance, followed by the N‐terminal and C‐terminal lines with similar resistance. …”
