Modelling and genetic dissection of staygreen under heat stress
Plant chlorophyll retention—staygreen—is considered a valuable trait under heat stress. Five experiments with the Seri/Babax wheat mapping population were sown in Mexico under hot-irrigated environments. Normalized difference ...
Natural variation in elicitation of defense-signaling associates to field resistance against the spot blotch disease in bread wheat (Triticum aestivum L.)
Spot blotch, caused by the hemibiotropic fungus Bipolaris sorokiniana, is amongst the most damaging diseases of wheat. Still, natural variation in expression of biochemical traits that determine field resistance to spot ...
Population structure of leaf pathogens of common spring wheat in the West Asian regions of Russia and North Kazakhstan in 2017
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2018)
Wheat diseases affecting leaves like leaf rust (Puccinia triticina), tan spot (Pyrenophora tritici-repentis) and spot blotch (Cochliobolus sativus = Bipolaris sorokiniana) are widely spread and potentially dangerous in the ...
Combining ability and heterosis in tropical maize (Zea mays L.) under heat stress
(Society of Pharmacognosy and Phytochemistry, 2018)
Maize cultivars tolerant to heat stress could play a pivotal role in adapting to the intermittent high temperature at critical growth stages and cope-up with climate-change induced high temperature spells. Field experiments ...
Can sub-Saharan Africa feed itself?
(National Academy of Sciences, 2016)
Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub-Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 ...
Genome-wide association for grain yield under rainfed conditions in historical wheat cultivars from Pakistan
Genome-wide association studies (GWAS) were undertaken to identify SNP markers associated with yield and yield-related traits in 123 Pakistani historical wheat cultivars evaluated during 2011–2014 seasons under rainfed ...
13C Natural Abundance of Serum Retinol Is a Novel Biomarker for Evaluating Provitamin A Carotenoid-Biofortified Maize Consumption in Male Mongolian Gerbils
Background: Crops such as maize, sorghum, and millet are being biofortified with provitamin A carotenoids to ensure adequate vitamin A (VA) intakes. VA assessment can be challenging because serum retinol concentrations ...
Conservation agriculture in maize- and wheat-based systems in the (Sub)tropics: Lessons from adaptation initiatives in South Asia, Mexico, and Southern Africa
Conservation agriculture's underlying principles—minimal soil disturbance, soil cover and crop rotation—are increasingly recognized as essential for sustainable agriculture. This article summarizes three contrasting cases ...
Earthworm activity and soil structural changes under conservation agriculture in central Mexico
Crop residue mulching combined with zero tillage and crop rotation, known as conservation agriculture (CA), is being promoted as an alternative system to revert soil degradation in maize-based farming in the central highlands ...
