From the very first presentation to the final wrap-up, the workshop was a deep dive into the challenges—and opportunities—plant science faces in the changing world of today… and probably the one of tomorrow.
An international study has found that forests with many tree species can store significantly more carbon than those with only one species.
A study reveals that sustainable agricultural practices can future-proof cocoa production. By enhancing pollination and mitigating climate risks, cocoa yields can increase without expanding plantations, supporting millions of farmers and the USD 100 billion chocolate industry while safeguarding biodiversity.
A new study finds that, of the three large-scale, plant-based climate mitigation strategies, reforestation stands out as most beneficial for biodiversity. In addition to reforestation (restoring forests in places where they have historically grown), the team of scientists modeled the impacts of afforestation (adding forests in places like grasslands and savannas) and bioenergy cropping (farming plants such as switchgrass for renewable energy) on more than 14,000 animal species.
Orphan crops, as the name implies, are often ignored. Yet, they have great potential to improve global food security. These underutilised plants, primarily grown in Africa, Asia, and South America, are staples in local diets but receive minimal attention in modern agriculture. Due to limited research and breeding advancements, they remain vulnerable to biotic and abiotic stresses.
Aspen forests face complex challenges from climate change, not just rising temperatures but interactions with drought, fire, and browsing. A 42% aspen mortality rate highlights vulnerabilities, especially for young trees in dry, low-elevation areas. Adaptive management and collaborative strategies are vital to support regeneration and maintain biodiversity in these essential ecosystems.
Ice age cycles had minimal impact on the genetic diversity of European trees, finds a new study. High diversity arose from traits like long lifespans and pollen traveling vast distances. This resilience offers hope for forests adapting to today’s rapid climate changes.
Phytoplankton blooms in Antarctic waters help slow ice shelf melting by 7%. These marine microbes trap heat near the surface and provide shade, cooling deeper waters and reducing the impact of sunlight. However, a feedback loop with iron from melting ice limits their growth, highlighting a complex climate interaction.
Researchers have uncovered genetic traits in wild tomatoes, specifically *Solanum pimpinellifolium*, that enhance salt stress tolerance. By analyzing plant vigor, shoot mass, and transpiration rates, they identified new genes linked to resilience in salty soils. These findings could inform breeding strategies to create more salt-tolerant crops, boosting agricultural sustainability.
