Saponin rich tropical fruits affect fermentation and methanogenesis in faunated and defaunated rumen fluid por Hess, H.D., Kreuzer, M., Díaz, T.E., Lascano Aguilar, Carlos Eduardo, Carulla, Juan E., Soliva, CR, Machmuller, A

“…Defaunation suppressed methanogenesis by 43% over all diets (P<0.05), and the effect of S. saponaria on methane was more pronounced in defaunated (29%) versus faunated rumen fluid (14%). When related to organic matter apparently fermented, differences relative to the control diet persisted (P<0.05), but methane release per unit of fibre degraded did not differ between the S. saponaria diet and the control diet. …”

Resistance to aflatoxin accumulation in kernels of maize inbreds selected for ear rot resistance in West and Central Africa por Brown, R.L., Chen, Z.Y., Menkir, A., Cleveland, T.E., Cardwell, K., Kling, J., White, D.G.

“…In 10 selected aflatoxin-resistant or aflatoxin-susceptible inbreds, Aspergillus flavus growth, which was quantified using an A. flavus transformant containing a GUS-β-tubulin reporter gene construct, was, in general, positively related to aflatoxin accumulation. However, one aflatoxin-resistant inbred supported a relatively high level of fungal infection, whereas two susceptibles supported relatively low fungal infection. …”

Maize–common bean intercropping to optimize maize-based crop production por Alemayehu, A., Tamado, T., Nigussie, D., Yigzaw, D., Kinde, T., Wortmann, Charles S.

“…Results indicated that land equivalent ratio was more than unity, and the intercrop system was 20% more productive relative to the sole crop. Maize equivalent yields were highest for most of the intercrop treatments relative to mono-crop maize with yield advantage of 14% from single row IPA with 128/20 kg N/P/ha. …”

An evaluation of the basis and consequences of a stay-green mutation in the navel negra citrus mutant using transcriptomic and proteomic profiling and metabolite analysis por Alos, Enriqueta, Roca, Maria, Iglesias, Domingo J., Mínguez-Mosquera, María I., Damasceno, Cynthia Maria Borges, Thannhauser, Theodore William, Rose, Jocelyn K. C., Talón, Manuel, Cercós, Manuel

“…Analysis of pigment composition in the wild- type and nan flavedo suggested that typical ripening- related chlorophyll ( Chl) degradation, but not carotenoid biosynthesis, was impaired in the mutant, identifying nan as a type C stay- green mutant. nan exhibited normal expression of Chl biosynthetic and catabolic genes and chlorophyllase activity but no accumulation of dephytylated Chl compounds during ripening, suggesting that the mutation is not related to a lesion in any of the principal enzymatic steps in Chl catabolism. …”
