Parasitic weeds devastate crops in food-insecure regions by hijacking plant signals. Scientists have found a way to trick these weeds into germinating when no host is present, causing them to die. Using engineered microbes, they’re producing key plant hormones to potentially turn this natural system into a powerful defense.
A genomic analysis of fine aroma cocoa from northern Peru revealed genetic divergence and evolutionary patterns within Theobroma cacao. The study identified 3 distinct genetic groups and estimated divergence times, suggesting that fine aroma cocoa diversified during the Pleistocene. The findings offer insights into cacao’s genetic structure and could aid in breeding and conservation efforts.
A research team has uncovered a shared stress response network in algae and plants, spanning 600 million years of evolution. Using advanced bioinformatics, they identified key genetic ‘hubs’ that shape responses to terrestrial stressors. This comprehensive dataset offers insights into the early adaptations of land plants.
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.
Ancient tree rings reveal how climate influenced Chinese dynastic history. Research on Qilian Juniper trees on the Tibetan Plateau shows arid periods coincided with dynastic upheavals. Understanding past climate impacts helps address current global climate change. The study highlights links between climate stress and societal unrest over millennia.
The Rubisco enzyme, responsible for capturing significant carbon from the atmosphere, is crucial for photosynthesis. Recent research has mapped mutant Rubisco molecules, unveiling potential enhancements in its function, which could revolutionize plant CO2 assimilation and adapt to future climates.
New study reveals that solar parks can enhance biodiversity through vegetation succession, where diverse plant species evolve over time. The study shows solar parks not only accommodate energy needs but also support ecosystems, highlighting a need for sustainable management practices, like grazing, to control plant growth and sustain biodiversity.
In the world’s longest-running ecological experiment, researchers found that increasing fertilizer use in agricultural grasslands reduces flower numbers five-fold and halves pollinator populations. Reducing fertilizer boosts biodiversity but lowers yields. A potential solution involves limiting nitrogen while maintaining other nutrients, preserving both crop productivity and pollinator diversity.
Researchers have developed a method to estimate hydrologic traits for 55,000 tree species, improving climate models without requiring massive field data collection. By analyzing evolutionary relationships, they infer missing data, enhancing Earth system models. This approach accelerates our understanding of plant-water interactions, crucial for predicting climate change impacts.
