Cassava may benefit from atmospheric change more than other crops

A recent study found that cassava can maintain its nutritional quality and photosynthetic efficiency even under elevated carbon dioxide levels. The crop showed significant yield increases of 22-39% in various varieties, making it a promising option for smallholder farmers in sub-Saharan Africa.

Timing key in understanding plant microbiomes

Researchers at Oregon State University have found that the order of microorganisms colonizing plants has a significant impact on microbiome composition and disease susceptibility. This discovery could provide farmers with important tools to combat plant diseases and maintain crop diversity.

Slow growth the key to long term cold sensing

Researchers have found a new temperature sensing mechanism in plants that uses slow growth to measure long-term changes in temperature. The study reveals that the protein NTL8 plays a crucial role in this process, accumulating slowly over time and being diluted by faster growth rates.

Climate change threat to tropical plants

A study by UNSW researchers found that tropical plants are more at risk from climate change than previously thought, with over 20% predicted to face temperatures above their upper limit. This is because they are near their maximum seed germination temperatures, and even small temperature increases could push them over the edge.

To listen is to survive: Unravelling how plants process information

Researchers at Helmholtz Munich identified hundreds of new information exchange points between plant proteins, revealing that most proteins function in multiple signaling pathways. This discovery may lead to new strategies for biotechnological development or breeding of plants to address climate change challenges.

Sneaky salmonella finds a backdoor into plants

Wild strains of salmonella have been found to reopen stomates on plants, allowing them to bypass the immune defense system and cause foodborne illnesses. This finding highlights the increasing threat of opportunistic pathogens jumping from plants to humans through contaminated foods.

How do plants forget?

Researchers found a phenomenon called 'epigenetic resetting' in plant sperm that erases histone modifications, allowing seeds to forget their environment. This mechanism is similar to data erasure on hard drives and is essential for plants to adapt to changing conditions.

Pollinator-friendly flowers planted along with crops aid bumblebees

A new study by UMass Amherst and NC State biologists found that flower strips benefit common Eastern bumblebees despite some plants increasing pathogen infection rates. The researchers created three conditions with canola plants and different types of flower strips, showing that bees reproduce more with flower strips than without.

Self-isolation or keep calm and carry on -- the plant cell's dilemma

Plant cells must balance trade-offs between communication, resource exchange, and protection against pathogens like fungi and bacteria. Researchers discovered that chitin perception in plasmodesmata triggers specific signaling pathways that allow cells to isolate themselves, regulating vital processes independently of immune responses.

Wallflowers could lead to new drugs

A team of researchers has identified the wallflower as a suitable model plant for discovering new cardenolides, which could lead to safer versions of heart disease and cancer treatments. The study provides a foundation for understanding the biosynthesis of cardenolides and their potential applications.

Ethylene sensor could help monitor plant health

Researchers developed an easy-to-use sensor that can sensitively detect changes in ethylene levels, a key hormone in plant health. The sensor uses a network of single-walled carbon nanotubes to monitor fluctuations in ethylene gas levels, with high sensitivity suitable for monitoring plants in the field.

New technique has potential to protect oranges from citrus greening

Researchers identified peptides that trigger immune responses in multiple plant species, including citrus, potentially preventing or reducing yield loss from citrus greening. This discovery offers a new hope for the devastated citrus industry, where no resistant varieties are available and limited disease control measures exist.
