National-scale changes in crop diversity through the Anthropocene. [PDF]

Sci Rep, 2021
International audienceExpansion of crops beyond their centres of domestication is a defining feature of the Anthropocene Epoch. This process has fundamentally altered the diversity of croplands, with likely consequences for the ecological functioning and

Persistence and Changes in Morphological Traits of Herbaceous Seeds Due to Burial in Soil

Agronomy, 2020
Seeds in soil banks can survive for many years before conditions become more suitable for germination. Meanwhile, seeds undergo changes in morphology and viability. In this study, we launched an artificial seed bank experiment that included 26 species of

The role of CGIAR Germplasm Health Units in averting endemic crop diseases: the example of rice blast in Bangladesh

CABI Agriculture and Bioscience, 2022
Background One of the less known benefits of the CGIAR is the facilitation of international agricultural research for crop improvement by providing a continuous supply of breeding materials for the development of disease resistant varieties.

Crop genetic erosion: understanding and responding to loss of crop diversity [PDF]

New Phytologist, 2021
SummaryCrop diversity underpins the productivity, resilience and adaptive capacity of agriculture. Loss of this diversity, termed crop genetic erosion, is therefore concerning. While alarms regarding evident declines in crop diversity have been raised for over a century, the magnitude, trajectory, drivers and significance of these losses remain ...

Which Seed Properties Determine the Preferences of Carabid Beetle Seed Predators?

Insects, 2020
Ground beetles are important invertebrate seed predators in temperate agro-ecosystems. However, there is a lack of information regarding which seed properties are important to carabids when they select seeds for consumption.

Regional and global shifts in crop diversity through the Anthropocene. [PDF]

PLoS One, 2019
The Anthropocene epoch is partly defined by anthropogenic spread of crops beyond their centres of origin. At global scales, evidence indicates that species-level taxonomic diversity of crops being cultivated on large-scale agricultural lands has ...

Crop Diversity for Yield Increase

PLoS ONE, 2009
Las prácticas agrícolas tradicionales sugieren que el cultivo de una mezcla de especies de cultivos en el mismo campo a través de la gestión temporal y espacial puede ser ventajoso para aumentar los rendimientos y prevenir enfermedades, pero la evidencia de las pruebas de campo a gran escala es limitada. El aumento de la diversidad de cultivos a través

Genetic Dissection of Root System Architectural Traits in Spring Barley

Frontiers in Plant Science, 2019
Breeding new crop cultivars with efficient root systems carries great potential to enhance resource use efficiency and plant adaptation to unstable climates. Here, we evaluated the natural variation of root system architectural traits in a diverse spring
