Rapid evolution aids spread of exotic plant species

Researchers at KU Leuven found that the Pyrenean rocket, a plant from southern Europe, genetically adapted rapidly to its new environment in Belgium, allowing it to spread quickly. This study provides evidence that rapid evolution can aid the spread of non-native plant species.

History to blame for slow crop taming: Study

Researchers found that crop domestication took much longer than expected, with cultural and historical factors playing a key role. Domesticated crops like corn showed traits such as seed resistance and shortened flowering times, but their adaptation was slower than genetic changes.

Optimizing sweet potato production

A study by researchers from Mississippi State and Louisiana State Universities reveals that early planting and delaying harvest can increase yield and economic benefits for sweetpotato producers. The results showed that marketable yield of the sweetpotato cultivars was consistently greater in early plantings than late plantings.

Birthplace of the domesticated chili pepper identified in Mexico

An international team of researchers, led by a plant scientist at the University of California, Davis, reports that the domesticated chili pepper originated in central-east Mexico. The region, extending from southern Puebla and northern Oaxaca to southeastern Veracruz, was previously thought to be less suitable for the crop's origins.

Drought hormones measured

Researchers at Carnegie Institution have developed a new method to measure abscisic acid levels in individual plant cells, shedding light on the hormone's role in plant stress responses. This breakthrough tool has the potential to improve crop yields and inform strategies for mitigating the impacts of drought and climate change.

Sugar, not oil

Scientists at Fraunhofer-Gesellschaft are producing isobutene from sugar using a microbial conversion process. The pilot plant, set to start in 2014, will have the potential to produce up to 100 tons of isobutene per year.

Studying crops, from outer space

Researchers have developed a new approach to measuring photosynthetic activity using satellite technology, providing direct observations of photosynthesis on a large scale for the first time. The study reveals that previous model-based estimates are too low and provides a tool to assess production in various regions.

Excessive deer populations hurt native plant biodiversity

A study by researchers from the University of Miami and University of Pittsburgh finds that high deer populations facilitate garlic mustard population explosion while suppressing native trillium plants. Deer exclusion reversed invasive species growth, supporting an ecological theory where native plants exert biotic resistance.

Lessons from a meadow

The study provides a detailed picture of biological events like flower blooming, animal emergence, and leaf fall, showing a more complex pattern than previously thought. Over 39 years, the flowering season expanded by more than a month due to earlier snowmelt and warming climate.

Plants convert energy at lightning speed

Scientists from Queen Mary University of London developed a novel method to quantify plant tolerance to high light intensity. The study found that plants grown without quick responses to high light had reduced capacity to protect themselves from damage.

Beneficial anti-inflammatory effects observed when plant extracts fed to sick pigs

Researchers found that feeding plant extracts to weanling pigs challenged with PRRS and E. coli reduced the frequency of diarrhea, improved feed efficiency, and altered gut morphology. The study suggests that these extracts may be used to alleviate disease symptoms in pigs.

Better broccoli, enhanced anti-cancer benefits with longer shelf life

Researchers at the University of Illinois discovered a method to increase broccoli's anti-cancer properties while prolonging its shelf life. The combined application of methyl jasmonate and 1-methylcyclopropene increased the presence of cancer-fighting agents in broccoli, while reducing ethylene levels that cause decay.

How evolution shapes the geometries of life
