The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: Genomic selection and association mapping in rice (Oryza sativa): effect of trait genetic architecture, training population composition, marker number and statistical model on accuracy of rice genomic selection in elite, tropical rice breeding lines

Jennifer Spindel, Hasina Begum, Deniz Akdemir, Parminder Virk, Bertrand Collard, Edilberto Redoña, Gary Atlin, Jean-Luc Jannink & Susan R. McCouch
Genomic Selection (GS) is a new breeding method in which genome-wide markers are used to predict the breeding value of individuals in a breeding population. GS has been shown to improve breeding efficiency in dairy cattle and several crop plant species, and here we evaluate for the first time its efficacy for breeding inbred lines of rice. We performed a genome-wide association study (GWAS) in conjunction with five-fold GS cross-validation on a population of 363...

Data from: Genetic diversity of the rain tree (Albizia saman) in Colombian seasonally dry tropical forest for informing conservation and restoration interventions

Evert Thomas, Carolina Adriana Aguirre-Morales, Cardozo Carlos Ivan, Janeth Gutiérrez, Carolina Alcázar Caicedo, Luis Gonzalo Moscoso Higuita, Becerra López-Lavalle Luis Augusto & Mailyn Adriana González
Albizia saman is a multipurpose tree species of seasonally dry tropical forests (SDTFs) of Mesoamerica and northern South America typically cultivated in silvopastoral and other agroforestry systems around the world, a trend that is bound to increase in light of multimillion hectare commitments for forest and landscape restoration. The effective conservation and sustainable use of A. saman requires detailed knowledge of its genetic diversity across its native distribution range of which surprisingly little is known...

Agroecological transformation for sustainable food systems : insight on France-CGIAR research

Data for: Interactions between breeding system and ploidy affect niche breadth in Solanum

Michael Kantar, Nathan Fumia, Daniel Rubinoff, Rosana Zenil-Ferguson, Michael Gore, Colin Khoury & Samuel Pironon
Understanding the factors driving ecological and evolutionary interactions of economically important plant species is important for sustainability. Niches of crop wild relatives, including wild potatoes (Solanum section Petota), have received attention, however, such information has not been analyzed in combination with phylogenetic histories, genomic composition, and reproductive systems. The data presented here provide publically available data on the geographic position, climatic niche, life-history (ploidy/mating system) and chloroplast phylogeny. These data were used to understand the...

Data from: Whole genome sequencing of elite rice cultivars as a comprehensive information resource for marker assisted selection

Jorge Duitama, Alexander Silva, Yamid Sanabria, Daniel Felipe Cruz, Constanza Quintero, Carolina Ballen, Mathias Lorieux, Brian Scheffler, Andrew Farmer, Edgar Torres, James Oard & Joe Tohme
Current advances in sequencing technologies and bioinformatics revealed the genomic background of rice, a staple food for the poor people, and provided the basis to develop large genomic variation databases for thousands of cultivars. Proper analysis of this massive resource is expected to give novel insights into the structure, function, and evolution of the rice genome, and to aid the development of rice varieties through marker assisted selection or genomic selection. In this work we...

Data from: Origins of food crops connect countries worldwide

Colin K. Khoury, Harold A. Achicanoy, Anne D. Bjorkman, Carlos Navarro-Racines, Luigi Guarino, Ximena Flores-Palacios, Johannes M. M. Engels, John H. Wiersema, Hannes Dempewolf, Steven Sotelo, Julian Ramírez-Villegas, Nora P. Castañeda Álvarez, Cary Fowler, Andy Jarvis, Loren H. Rieseberg & Paul C. Struik
Research into the origins of food plants has led to the recognition that specific geographical regions around the world have been of particular importance to the development of agricultural crops. Yet the relative contributions of these different regions in the context of current food systems have not been quantified. Here we determine the origins (‘primary regions of diversity’) of the crops comprising the food supplies and agricultural production of countries worldwide. We estimate the degree...

Effect of Drought Stress on the Genetic Architecture of Photosynthate Allocation and Remobilization in Pods of Common Bean (Phaseolus vulgaris L.), a Key Species for Food Security

Paul Gepts, Jorge Carlos Berny Mier Y Teran, Enéas R. Konzen, Antonia Palkovic, Siu M. Tsai, Idupulapati M. Rao & Stephen Beebe
Background: Common bean is the most important staple grain legume for direct human consumption and nutrition. It complements major sources of carbohydrates, including cereals, root crop, or plantain, as a source of dietary proteins. It is also a significant source of vitamins and minerals like iron and zinc. To fully play its nutritional role, however, its robustness against stresses needs to be strengthened. Foremost among these is drought, which commonly affects its productivity and seed...
