What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress.
Anyone who has taken a long road trip or bike ride has used a product of the spurge plant family — rubber. The spurge family, or Euphorbiaceae, includes economically valuable plants like the rubber tree, castor oil plant, poinsettia and cassava. Newly identified fossils found in Argentina suggest that a group of spurges took a trip of their own tens of millions of years ago. Driven by climatic changes and land movements over millennia, a group of spurges relocated thousands of miles from ancient South America to Australia, Asia and parts of Africa.
Plant species become exotic after being accidentally or deliberately transported by humans to a new region outside their native range, where they establish self-perpetuating populations that quickly reproduce and spread. This is a complex process mediated by many factors, such as plant traits and genetics, which challenges the creation of general guidelines to predict or manage plant invasions.
A total of 57 institutions around the world share their expertise in a ground-breaking study which highlights the urgent need to protect the world’s forests from non-native pests amid climate change.
Plant roots have their own thermometer to measure the temperature of the soil around them and they adjust their growth accordingly. Through extensive experiments, researchers were able to demonstrate that roots have their own temperature sensing and response system. In a new study theyalso provide a new explanation for how roots themselves detect and react to higher temperatures. The results could help develop new approaches for plant breeding.
New research looking at the evolution of terrestrial orchid species has found that global cooling of the climate appears to be the major driving factor in their diversity. The results help scientists understand the role of global climate on diversity of species, and how our current changing global climate might affect biodiversity in the future.
Using a newly available genome sequence of grass pea (Lathyrus sativus L.) a research team has identified key biochemical steps that lead to the production of the neurotoxin β-L-ODAP (ODAP).
A team of scientists have conducted a new study which shows that three ways to fight the invasive Prosopis juliflora tree in Ethiopia, Kenya and Tanzania all proved very effective in almost all cases.
Plants use photosynthesis to produce oxygen, nutrients and bioenergy. But this complex biochemical process is inefficient, with only a fraction of the sun’s energy actually being utilized in photosynthesis. Researchers want to change this in order to help increase the yield of cultivated crops. A research team has now discovered that the outer envelope membrane of chloroplasts could play a key role in this process.
CONSTANS (CO), a well-known member of the B-box family, is the major component of the photoperiodically regulated flowering and circadian pathways in Arabidopsis (Arabidopsis thaliana). A new study showed that CONSTANS protein negatively modulated salinity tolerance in Arabidopsis by physically associating with and antagonizing the ABSCISIC ACID-RESPONSIVE ELEMENT BINDING FACTOR (ABF) transcription factors under long-day conditions.
