Cassava genome from a wild ancestor to cultivated varieties
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/51712
Abstract
Cassava is a major tropical food crop in the Euphorbiaceae family that has high carbohydrate production potential and adaptability to diverse environments. Here we present the draft genome sequences of a wild ancestor and a domesticated variety of cassava and comparative analyses with a partial inbred line. We identify 1,584 and 1,678 gene models specific to…

Role of fixing nitrogen in common bean growth under water deficit conditions
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/102495
Abstract
In common bean (Phaseolus vulgaris L), limited information is available if potential of nodulation and symbiotic nitrogen fixation is associated with the expression of traits that confer better adaptation to drought conditions. Adaptive traits were therefore measured in N‐fixing bean lines BAT 477, DOR 364, and PAN 185 and in nonnodulating…

Expression of the Aeluropus littoralis AlSAP Gene Enhances Rice Yield under Field Drought at the Reproductive Stage
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/81532
Abstract
We evaluated the yields of Oryza sativa L. ‘Nipponbare’ rice lines expressing a gene encoding an A20/AN1 domain stress-associated protein, AlSAP, from the halophyte grass Aeluropus littoralis under the control of different promoters. Three independent field trials were conducted, with drought imposed at…

CGIAR genebank viability data reveal inconsistencies in seed collection management
https://hdl.handle.net/10568/114360
Abstract
Genebanks underpin global food security, conserving and distributing agrobiodiversity for use in research and breeding. The CGIAR collections include >700,000 seed accessions, held in trust as global public goods. However, the role of genebanks in contributing to global food security can only be realized if collections are effectively managed. Examination of the historical viability monitoring data from…

Single strand conformation polymorphism based SNP and Indel markers for genetic mapping and synteny analysis of common bean (Phaseolus vulgaris L.)
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/44104
Abstract
Expressed sequence tags (ESTs) are an important source of gene-based markers such as those based on insertion-deletions (Indels) or single-nucleotide polymorphisms (SNPs). Several gel based methods have been reported for the detection of sequence variants, however they have…

Biological control of an agricultural pest protects tropical forests
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/103610
Abstract
Though often perceived as an environmentally-risky practice, biological control of invasive species can restore crop yields, ease land pressure and thus contribute to forest conservation. Here, we show how biological control against the mealybug Phenacoccus manihoti (Hemiptera) slows deforestation across Southeast Asia. In Thailand, this newly-…

Abstract
We identified the most sensitive genotype-specific parameters (GSPs) and their contribution to the uncertainty ofthe MANIHOT simulation model. We applied a global sensitivity and uncertainty analysis (GSUA) of the GSPs tothe simulation outputs for the cassava development, growth, and yield in contrasting environments…

https://hdl.handle.net/10568/97096
Abstract
Micronutrient malnutrition affects 2 billion people worldwide and biofortification could prove to be a cost-effective solution to its alleviation. The aims of this study are as follows: (i) to understand consumer acceptance of the main sensory characteristics such as taste, color, texture, etc., of an iron…

Gene-based SNP discovery in tepary bean (Phaseolus acutifolius) and common bean (P. vulgaris) for diversity analysis and comparative mapping
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/72712
Abstract
Background
Common bean (Phaseolus vulgaris) is an important grain legume and there has been a recent resurgence in interest in its relative, tepary bean (P. acutifolius), owing to this species’ ability to better withstand abiotic stresses. Genomic resources are scarce for this…

Abstract
More than two billion people are micronutrient deficient. Polished grains of popular rice varieties have concentration of approximately 2 μg g−1 iron (Fe) and 16 μg g−1 zinc (Zn). The HarvestPlus breeding programs for biofortified rice target 13 μg g−1 Fe and 28 μg g−1 Zn to reach approximately 30% of the estimated average requirement…

Les mauvaises herbes dans nos cultures constituent une contrainte pour les paysans, lesquels dans la mesure du possible conjuguent beaucoup d'efforts afin de les éradiquer. Outre cet aspect de nuisance, les mauvaises herbes pourraient aussi être utilisées pour la prédiction de la fertilité du sol. C'est ainsi qu'une…
