Gamma-Irradiated Female Aedes aegypti Mosquitoes Exhibit Greater Susceptibility to Mayaro Virus.

Mayaro virus (MAYV) is an alphavirus endemic in many parts of Central and South America transmitted to humans by Aedes aegypti. Currently, there is no vaccine or treatment of Mayaro infection, and therefore it is essential to control transmission by reducing populations of Ae. aegypti.

Nitrogen (N) and phosphorus (P) are limiting factors for crop production in Rwanda where food security is susceptible to inadequate agricultural techniques, especially fertilization. Understanding N and P footprints for food and their budgets under different fertilized scenarios may help to improve the nutrient use efficiency and crop yield in Rwanda, however, with little information available yet. Here, we estimated food N and P footprints and their budgets for agri-food system in Rwanda using adjusted N-P-Calculator model under fertilized, unfertilized and combined scenarios during 1961-2020.

Plants (Basel)
December 2022
Excellence Unit 'María de Maeztu' 2020-23, Department of Agronomy, Campus de Rabanales, University of Cordoba, 14071 Cordoba, Spain.
It is known that high N doses, N/K imbalances, and frequent irrigation favor Verticillium wilt. The influence of fertilization and its interaction with the frequency of irrigation on the development of Verticillium wilt of olive (VWO) has been evaluated. A split-split-plot design in microplots with two naturally infested soils of different texture was established for studying three fertilization treatments (NOCa, NPK and without fertilization), plus two irrigation frequencies (daily and deficit).

Article Synopsis
- The study examined the traits of tree coarse roots used for afforestation in Mongolia's semi-arid steppe, focusing on various watering regimes and types of soil fertilization.
- Root length increased with higher watering levels, while fertilization generally suppressed root growth and reduced rooting depth.
- Unfertilized trees showed better adaptability in root diameter to wind, suggesting a need for understanding root responses in afforestation practices to improve resilience against climate change.
Effective Pollen-Fertility Restoration Is the Basis of Hybrid Rye Production and Ergot Mitigation.

Hybrid rye breeding leads to considerably higher grain yield and a higher revenue to the farmer. The basis of hybrid seed production is the CMS-inducing Pampa (P) cytoplasm derived from an Argentinean landrace and restorer-to-fertility () genes. European sources show an oligogenic inheritance, with major and minor genes, and mostly result in low-to-moderate pollen-fertility levels.
