Three new teosintes (Zea spp., Poaceae) from Mexico
Premise of the study : Teosinte species are the closest relatives of maize and represent an important but increasingly rare genetic resource for maize improvement and the study of evolution by domestication. Three ...
Characterization of a global germplasm collection and its potential utilization for analysis of complex quantitative traits in maize
Association mapping is a powerful approach for exploring the molecular basis of phenotypic variations in plants. A maize (Zea mays L.) association mapping panel including 527 inbred lines with tropical, subtropical and ...
Productivity differences and food security: a metafrontier analysis of rain-fed maize farmers in MasAgro in Mexico
(AIMS Press, 2017)
Rain-fed maize production in Mexico includes approximately 6 million hectares which variation in productivity represents huge challenges to meeting the sustainable intensification goals of the Sustainable Modernization of ...
Aggregation and C and N contents of soil organic matter fractions in a permanent raised-bed planting system in the highlands of Central Mexico
Permanent raised bed planting with crop residue retention is a form of conservation agriculture that has been proposed as an alternative to conventional tillage for wheat production systems in the Central Highlands of ...
Genome-wide association for plant height and flowering time across 15 tropical maize populations under managed drought stress and well-watered conditions in Sub-Saharan Africa
(Crop Science Society of America, 2016)
Genotyping breeding materials is now relatively inexpensive but phenotyping costs have remained the same. One method to increase gene mapping power is to use genome-wide genetic markers to combine existing phenotype ...
Forward genetics by sequencing EMS variation induced inbred lines
(Genetics Society of America, 2017)
In order to leverage novel sequencing techniques for cloning genes in eukaryotic organisms with complex genomes, the false positive rate of variant discovery must be controlled for by experimental design and informatics. ...
Identification and functional characterization of the AGO1 ortholog in maize
Eukaryotic Argonaute proteins play primary roles in miRNA and siRNA pathways that are essential for numerous developmental and biological processes. However, the functional roles of the four ZmAGO1 genes have not yet been ...
The evolving maize sector in Asia: Challenges and opportunities
Asia's maize (Zea mays L.) sector has shown rapid growth during the last few decades. This article reviews the evolving maize sector in Asia, focusing on the eight main maize-producing countries: China, India, Indonesia, ...
Stay-green and associated vegetative indices to breed maize adapted to heat and combined Heat-Drought Stresses
The objective of this study was to assess the importance of stay-green on grain yield under heat and combined heat and drought stress and to identify the associated vegetative indices allowing higher throughput in order ...
The usefulness of iron bioavailability as a target trait for breeding maize (Zea mays L.) with enhanced nutritional value
Iron (Fe) deficiency is the most widespread nutritional problem, affecting as many as half of the world's population. Only a small fraction (2?15%) of Fe from plant sources is typically bioavailable, that is, available for ...
