Breeding for productivity and quality: Evidence from Argentina’s INTA rice program

Sustained investment in agricultural research and development (R&D) is critical for productivity growth, food security, and competitiveness; yet, globally, public investment has stagnated relative to the size of the agricultural sector. This study evaluates the production, econom...

Genetic variability and DMI fungicide sensitivity of the Alternaria alternata species group associated with wheat in Uruguay

This study provides the first assessment of occurrence, genetic variability, and DMI fungicide sensitivity of wheat-associated Alternaria spp. in Uruguay. Seventy asymptomatic wheat grain samples collected during the 2022 harvest were analyzed. Alternaria spp. were detected in al...

Differential responses of Uruguayan onion cultivars to bacterial bulb rot and leaf blight caused by Pantoea spp. and Burkholderia sp

Bacterial diseases caused by Pantoea spp. are an emerging constraint for onion production in Uruguay. This study evaluated bacterial aggressiveness and the response of Uruguayan onion cultivars and breeding lines. P. ananatis MAI6032, P. agglomerans MAI6045, and Burkholderia sp....

Community-level AM fungal interactions lead to unexpected growth and disease outcomes in tomato

Abstract Background and Aims Arbuscular mycorrhizal (AM) fungi can enhance plant growth and resistance to pathogens through Mycorrhiza-Induced Resistance (MIR). While individual AM fungal species differ in their effects on plant performance, the consequences of multi-species AM f...

The Potential Inhibitory Effect of Copper and Nickel on Gaseous Soil N Emissions

Nickel (Ni) and copper (Cu) are essential soil micronutrients that are beneficial for plant growth and development when applied at the right levels to deficient soils. However, they can also be of concern if excessive application leads to accumulation in soil, causing soil fertil...

A pair of duplicated SOC1 genes, DcSOC1-1 and DcSOC1-2, control vernalization requirement in carrot

Abstract Background Carrot vernalization requirement (VR), the amount of cold exposure needed for plants to become vernalized, strongly influences geographical adaptation of the crop and many agricultural practices, and this trait defines annual vs. biennial cultivars. Despite it...
