Unlikely wasp enemy of a serious alien pest in North America named Idris elba
While a mention of the British movie and music star is missing in its description, the species might prove to be a Heimdall-like ‘protector’ for many crops
Lichens are way younger than scientists thought
You’ve probably seen a lichen, even if you didn’t realize it. If you’ve ever meandered through the forest and wondered what the crusty stuff on trees or rocks was, they’re lichens, a combination of algae and fungi living together almost…
The global distribution of freshwater plants is controlled by catchment characteristics
Globally, photosynthetic modes of terrestrial plants are influenced by climatic factors such as adaptations to variation in air temperature and water availability. In water, CO2 often limits photosynthesis because it moves 10,000-times slower than in air and, thus, rapid photosynthesis…
Amazon deforestation and number of fires show summer of 2019 not a ‘normal’ year
The fires that raged across the Brazilian Amazon this summer were not ‘normal’ and large increases in deforestation could explain why, scientists show.

Visualizing heat flow in bamboo could help design more energy-efficient and fire-safe buildings
Modified natural materials will be an essential component of a sustainable future, but first a detailed understanding of their properties is needed. The way heat flows across bamboo cell walls has been mapped using advanced scanning thermal microscopy, providing a…
Plants might be helping each other more than thought
Contrary to the long-held belief that plants in the natural world are always in competition, new research has found that in harsh environments mature plants help smaller ones – and thrive as a result. The first study to examine plant…
Chitin-binding proteins override host plant’s resistance to fungal infection
An insoluble complex carbohydrate, chitin makes up fungal walls and plays a significant role in the interaction between fungal pathogens and their plant hosts. Plant cells harbor immune receptors that perceive chitin and work to stop fungal infection. However, fungal…
System by which plants have formed secondary buds since ancient times illuminated
A collaborative research group has succeeded in identifying an important transcription factor, GCAM1, which allows liverwort plants to asexually reproduce through creating clonal progenies (vegetative reproduction). Furthermore, this transcription factor was revealed to have the same origin as those which…

Experts unlock key to photosynthesis, a find that could help us meet food security demands
Scientists reveal ‘beating heart’ of photosynthesis that is responsible for significantly influencing plant growth. Study shows how an electrical reaction in protein complex cytochrome b6f provides the energy that plants need to turn carbon dioxide into the carbohydrates and biomass…

Knowledge of the origin of the food makes it taste better
Well-known foods taste the best, but if we know where the food comes from and how it is made, it gets better, even if we don’t think the taste is spot on. New research from Future Consumer Lab at the University of Copenhagen demonstrates this.
University of Florida scientists advance citrus greening research efforts
Citrus greening, a devastating disease, has reduced Florida citrus production by 70%, according to most accounts. Efforts to develop disease control methods have been stymied because scientists have been unable to culture and experimentally manipulate the causal bacterial pathogen, Candidatus…

Researchers find nature’s backup plan for converting nitrogen into plant nutrients
Although nitrogen is essential for all living organisms — it makes up 3% of the human body — and comprises 78% of Earth’s atmosphere, it’s almost ironically difficult for plants and natural systems to access it. Atmospheric nitrogen is not…
New findings on nitrous oxide emissions from northern trees surprised scientists
A recently published study, completed by researchers from the University of Helsinki together with Dr Katerina Machacova, a visiting scholar, demonstrates that boreal forests of the Northern Hemisphere are sources of the greenhouse gas nitrous oxide (N2O). The study provides…
Evolutionary diversity is associated with Amazon forest productivity
An international team of researchers led by the University of Leeds have revealed for the first time that Amazon forests with the greatest evolutionary diversity are the most productive. The team used long term-records from 90 plots as part of…
What’s the story, morning glory? Taxonomy, evolution and sweet potatoes
This indicates that the storage root was an already-existing trait that predisposed the plant for cultivation and not solely the result of human domestication, as previously thought. This discovery, published today in Nature Plants , is part of a comprehensive…
Too much sugar doesn’t put the brakes on turbocharged crops
Plants make sugars to form leaves to grow and produce grains and fruits through the process of photosynthesis, but sugar accumulation can also slow down photosynthesis. Researching how sugars in plants control photosynthesis is therefore an important part of finding…
Hot town, springtime in the city: Urbanization delays spring plant growth in warm regions
GAINESVILLE, Fla. — The first appearance of bright green leaves heralds the start of spring, nudging insects, birds and other animals into a whirlwind of action. But a new study shows that urbanization shifts this seasonal cue in nuanced ways,…

Research suggests fumigants have very low long-term impact on soil health
It started with curiosity. How does a fumigant, commonly used for nematode management in potato cropping systems, influence soil microbial communities? To explore this question, scientists at Colorado State University and Oregon State University used high-throughput sequencing techniques to investigate…
Introducing GMpi: Affordable and adaptable remote monitoring for plant growth experiments
Growth chambers are a cornerstone of laboratory-based plant science, allowing for the tightly controlled conditions necessary for many experimental designs. However, these conditions can sometimes be a little less than controlled, creating headaches ranging from reproducibility issues to the loss…
