The health of plants depends on numerous environmental factors. All plants, including trees, live in close relationship with microorganisms. Plants harbor microbial communities in above-and below-ground tissues, where plant-associated microbial communities are influenced by environmental conditions and host genotype. The microbiome of trees is composed of mutualistic, commensal, and pathogenic microorganisms. Mutualistic microorganisms can help trees obtain nutrients (e.g., phosphorus and nitrogen) and defend against plant pathogens.

El presente documento se realizó en el marco de la Mesa Tecnológica de Oleaginosas del Uruguay (MTO). Esta información y los Períodos de Seguridad (PS) indicados, pretenden ser una guía para ayudar a la toma de decisiones de técnicos y productores de colza con la finalidad de disminuir el riesgo de superar los mismos. Se recuerda el uso exclusivo de los productos registrados para colza y consultar a los técnicos asesores para definir la conveniencia del tratamiento y la elección del producto.

British and Northern Irish agri-food systems are faced with the challenge of reducing their supplychain emissions of greenhouse gases (GHGs) such as nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) in line with the UK's ambition of achieving a cross-sector 'net zero' economy by 2050. Approximately 10% of the GHG emissions are generated by agriculture, and approximately 56% of these GHGs are generated by livestock in the form of CH4 from enteric fermentation (eructation primarily) and manure management (i.e., storage and subsequent application as an organic fertiliser).

Land transformation is a major component of global change, directly altering habitat composition and spatial configuration, biodiversity, and ecosystem functioning. Over the last decades, the Dry Chaco region in Northwestern Argentina has become one of the regions most heavily transformed worldwide due to the expansion of its agricultural frontier. Many questions remain unanswered about how this process of change occurred. In this study, a parcel-scale database was used to assess the conversion of natural landscapes to different agroecosystems.

There are several plant below-ground biomass databases for grasslands, but the contribution from the southern hemisphere is minimal. Particularly, no study has compiled the published values of plant below-ground biomass for the temperate subhumid grasslands of South America. In these grasslands, called Río de la Plata grasslands, grazing is the most frequent disturbance.

Key message:Here, we provide an updated set of guidelines for naming genes in wheat that has been endorsed by the wheat research community. Abstract:The last decade has seen a proliferation in genomic resources for wheat, including reference- and pan-genome assemblies with gene annotations, which provide new opportunities to detect, characterise, and describe genes that influence traits of interest.
