Deficiency causes appetite for meat

Researchers at the University of Würzburg discovered that Triphyophyllum peltatum can transform into a carnivorous plant under phosphorus deficiency. The plant captures small insects using adhesive traps to access essential nutrients.

Mutant with counting disability

A Venus flytrap mutant with a genetic defect has lost its ability to count prey touch numbers. Researchers analyzed gene expression patterns and calcium signaling pathways to understand the cause of the numerical disability.

The best offense is a great defense for some carnivorous plants

Researchers discovered that plant carnivory evolved from calcium molecules' dynamic movement within cells in response to touch from live prey. This finding broadens our understanding of how plants interact with their environments and may lead to the development of crops that can survive in challenging conditions.

New carnivorous plant must balance trapping prey and being pollinated

Researchers have discovered a new carnivorous plant, Triantha occidentalis, that traps insects near its insect-pollinated flowers, avoiding the death of potential pollinators. The plant's sticky hairs only entrap small midges and insects, allowing larger bees and butterflies to act as pollinators.

Little crop of horrors

Researchers are investigating how carnivorous plant genes can help crops defend themselves from pathogens and insects, reducing reliance on pesticides and fertilizers. The team plans to test transgenic crop plants with protein-based pest deterrents and nutrient-enhancing traits.

'Save me Seymour!'

A recent study by Curtin University reveals that approximately a quarter of the world's carnivorous plant species are at risk of extinction. The biggest threats to these unique plants are human activities such as agriculture, mining, and climate change, which can lead to habitat loss and hydrological changes.

How Venus flytraps snap

A new study reveals that a single slow touch on the Venus flytrap's trigger hair can also trigger trap closure, allowing it to catch slow-moving larvae and snails. The researchers used highly sensitive sensors and mathematical models to determine the forces needed to trigger the mechanism.

Nature's secret recipe for making leaves

Researchers from the John Innes Centre discovered that simple shifts in gene activity in the leaf bud provide a flexible mechanism for forming leaves of all shapes and sizes. The study reveals how cup-shaped leaves evolved from flat sheets through simple genetic changes, offering a simple mechanistic explanation for diverse leaf forms.

A varied menu

Researchers found that the carnivorous waterwheel plant catches a wide variety of prey, including fast-swimming animals and slow-moving snails. The plant's diverse diet may be an adaptation to its fragmented habitats.

Sundews just want to be loved

Research reveals that carnivorous plants like sundews prioritize pollination over insect safety, with taller flowers attracting more visitors. A study of two sundew species found that longer stems increased flower visits by ten times compared to shorter ones.
