Recovered wild maize gene boosts crop protein without yield loss
Recovered wild maize gene boosts crop protein without yield loss Gaby Clark Scientific Editor Robert Egan Associate Editor Maize (Zea mays L.) plays an important role in global food security. During 9,000 years of maize domestication and breeding, however, protein content was not a major breeding target. Consequently, many beneficial gene variants associated with higher protein content were gradually lost from cultivated maize.
Aerial imagery and deep learning accurately estimate maize foliar disease severity
Southern leaf blight (SLB) is a foliar disease of maize (Zea mays L.) caused by the necrotrophic fungal pathogen Cochliobolus heterostrophus. Genetic resistance is the most effective control method for SLB. Developing disease resistant maize lines requires field trials during which disease phenotypes must be visually assessed.
A maize gene that coordinates flowering aids drought resistance
Nature, Published online: 03 June 2026; doi:10.1038/d41586-026-01745-9The synchronous flowering of male and female flower clusters in maize is crucial, but drought disrupts this synchrony, leading to considerable yield losses. A gene called SAUR72 is shown to preserve flowering synchrony in drought conditions, offering a potential strategy for breeding drought-resilient maize varieties.
Plastoglobules compartmentalize nitrogen assimilation in maize
Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10610-8Chloroplast plastoglobules act as nitrogen-assimilation hubs in maize, with key enzymes enhancing nitrogen-use efficiency and offering new strategies for developing high-yield, sustainable crops.
Teosinte alleles enhance nitrogen assimilation and seed protein in maize
Nature, Published online: 03 June 2026; doi:10.1038/s41586-026-10575-8Teosinte alleles enhance nitrogen assimilation and seed protein without lowering crop yield when expressed in modern maize, providing a powerful strategy for crop improvement to meet future population demands.
Tiny hubs of metabolic activity optimize nitrogen use in maize
Nature, Published online: 03 June 2026; doi:10.1038/d41586-026-01583-9Structures called plastoglobules organize the enzymes that turn nitrogen into compounds needed for plant growth, offering lessons for sustainable agriculture.
Painting the growing season in the Maize Triangle
Radar data from an agricultural area in South Africa, shown in a vivid color palette, reveal crop types and how they changed during the Southern Hemisphere's growing season.
Great mysteries of archaeology: An ancient Amazonian world revealed from the sky
Great mysteries of archaeology: An ancient Amazonian world revealed from the sky Gaby Clark Scientific Editor Andrew Zinin Lead Editor From the air, you see it only through the constant jolt, tilt, and shudder of the low-flying Cessna aircraft. The landscape of the Llanos de Moxos, northern Bolivia, appears as a disconnected patchwork of open grassland savannahs, forest islands, and lakes. It feels random, almost unreadable.
