[科研项目 ] ADAPT project’s success: Paving the way for future-proof potatoes amidst climate challenges 进入全文
ADAPT
The ADAPT project (“Accelerated Development of multiple-stress tolerAnt PoTato”), which officially concluded on 28 October, has made substantial strides in improving the resilience of potatoes to environmental stresses. Launched in July 2020, the project had a total budget of 5 million Euros from the EU Horizon 2020 program (No GA 2020 862-858). The international consortium worked diligently to develop strategies to prepare potatoes for the challenging growth conditions of the future, based on a detailed understanding of molecular processes related to stress acclimation. The ADAPT project united a team of ten leading academic research institutions, four potato breeders, a screening technology developer, a government agency, and a non-profit EU association. Together, they investigated the mechanisms underlying multi-stress resilience in potato. Their aim was to ensure that the potato could better withstand various environmental stresses, particularly heat and drought, which are becoming more common due to climate change. Over the course of four years, the ADAPT project made significant advancements, including: 1.Understanding Potato Stress Acclimation. The project gained valuable insights into how potatoes react to heat, drought, and waterlogging, offering a better understanding of stress acclimation in potatoes. 2.Potato Stress Resilience.The team investigated how different potato genotypes handle combined abiotic stress under real-world field conditions, providing new data on the resilience of various potato varieties. 3.Advanced Phenotyping and Field Trials.High-throughput phenotyping and field trials were conducted using drones and environmental sensors, helping to refine the data on potato stress resilience. 4.Insights into Stress Adaptation in Potatoes. By monitoring critical growth stages and tuber formation, the project identified specific molecular responses and stress signatures, which can be explored in future breeding programs. 5.Powerful Data Analysis Pipelines.The project established robust analysis pipelines for processing large datasets from field trials and high-throughput studies across multiple commercial potato varieties. 6.Utilizing Knowledge Networks. The improved understanding of stress reactions has laid the foundation for fine-phenotyping and marker development, essential for future potato breeding programs.

TIME
Industrial meat’s livestock farming causes 11% of greenhouse emissions, according to the UN's Food and Agriculture Organization, but most people are not ready to cut meat from their diets. The Netherlands-based Meatable is addressing those problems with genuine animal meat grown in a lab, with its patented Opti-Ox technology. The process uses stem cells taken from a living pig, putting them through a fermentation-like process that dramatically amplifies their growth and differentiation into the muscle and fat that comprise real meat—in just four days. Meatable plans to bring its pork product to market in Singapore next year. Company co-founder and CTO Daan Luining stresses that the product “isn’t like meat—it is meat.”

[学术文献 ] Forage conservation is a neglected nitrous oxide source 进入全文
PNAS Nexus
Agricultural activities are the major anthropogenic source of nitrous oxide (N2O), an important greenhouse gas and ozone-depleting substance. However, the role of forage conservation as a potential source of N2O has rarely been studied. We investigated N2O production from the simulated silage of the three major crops—maize, alfalfa, and sorghum—used for silage in the United States, which comprises over 90% of the total silage production. Our findings revealed that a substantial N2O could be generated, potentially placing forage conservation as the third largest N2O source in the agricultural sector. Notably, the application of chlorate as an additive significantly reduced N2O production, but neither acetylene nor intermittent exposure to oxygen showed any impact. Overall, the results highlight that denitrifiers, rather than nitrifiers, are responsible for N2O production from silage, which was confirmed by molecular analyses. Our study reveals a previously unexplored source of N2O and provides a crucial mechanistic understanding for effective mitigation strategies.

[学术文献 ] Harnessing clonal gametes in hybrid crops to engineer polyploid genomes 进入全文
Nature
Heterosis boosts crop yield; however, harnessing additional progressive heterosis in polyploids is challenging for breeders. We bioengineered a ‘mitosis instead of meiosis’ (MiMe) system that generates unreduced, clonal gametes in three hybrid tomato genotypes and used it to establish polyploid genome design. Through the hybridization of MiMe hybrids, we generated ‘4-haplotype’ plants that encompassed the complete genetics of their four inbred grandparents, providing a blueprint for exploiting polyploidy in crops.
