Researchers at Washington State University have discovered how a barley plant recognizes an invader within five minutes of an attack, triggering its defenses. This breakthrough could lead to new ways to battle crop diseases, potentially defeating evolving threats like Ug99.
Researchers discovered that plant cells use a distinct transmembrane signaling mechanism involving a small steroid molecule, unlike animal cells. This novel approach enables plants to grow and respond to external signals.
Researchers at the Salk Institute identified a signaling molecule called heme that drives expression of photosynthesis-related genes. This discovery may help plants overcome stress and improve growth, leading to increased crop yields and better plant health.
A study led by Professor Graham Packham of the University of Southampton shows that watercress compounds can block a critical pathway linked to cancer development. The research found that eating watercress may interfere with the function of protein HIF, which plays a role in tumor growth.
Researchers at the Max Planck Institute for Chemical Ecology have discovered a new electrical signal transmission system in plants called 'system potential', which is induced by wounding and can carry different information. This novel system allows plants to rapidly respond to insect herbivory and activate their defense mechanisms.
Researchers at CSHL identify a family of mobile small RNAs, called ta-siRNAs, that act like morphogens to establish the top/bottom axis in leaves. These RNA molecules generate a concentration gradient across each leaf, dividing cells into distinct sections with sharply drawn boundaries.
A study by Carnegie Institution researchers identified key links in the steroid signaling chain using proteomics. Key kinases called BSKs were found to respond to brassinosteroids, filling a major gap in understanding plant hormone regulation.
Researchers at Norwich BioScience Institutes discover that cells at the margins of leaves and petals secrete a mobile growth signal controlling size. This signal is distinct from classical plant hormones, influencing leaf division until a certain threshold is reached.
Researchers uncover the elusive signal that triggers plantwide resistance, found to be methyl salicylate, an aspirin-like compound.
Researchers found endosomes facilitate plant growth through brassinosteroid receptor trafficking, affecting shoot and root growth. This discovery expands understanding of endosome function in plants, shedding light on their evolutionary origins.
Researchers have identified the FT protein as a key player in signaling flowering in squash plants, using an obligate short-day plant system. The study provides strong evidence that FT protein acts as a florigenic signal, and its presence in the phloem sap of flowering plants supports this conclusion.
Researchers have identified a specific class of small peptide elicitors that help plants react to insect attack, triggering defensive chemistry and improving protection against pests. The discovery opens the door for genetic manipulation of plants with improved defense mechanisms.
Researchers at Imperial College London discovered that a protein called Flowering Locus T Protein (FT) plays a crucial role in plant flowering. The FT protein travels from leaves to the shoot apex, triggering the production of genes that cause flowers to bloom.
Researchers found a single pathway that channels distress signals from chloroplasts to the nucleus in plants, enabling the activation or deactivation of certain genes. This 'master switch' could lead to new generations of plants with improved drought and stress tolerance.
Research suggests that nitric oxide and nitrite released by pollen grains trigger allergic responses in the nose. The study, funded by the Wellcome Trust, aims to investigate the role of these compounds in human cell inflammation during hayfever.
Researchers at the Salk Institute discovered that GUN1, a nuclear-encoded protein, plays a crucial role in transmitting distress signals from damaged chloroplasts to the nucleus, triggering a shutdown of photosynthetic genes. This finding sheds light on the complex communication between organelles and the nucleus.
Researchers at Ohio State University developed a satellite radar technique to measure water levels in vegetated wetlands. The study found rising and dropping water levels in selected sites over a decade, including changes caused by seasonal rainfall.
Researchers at the Salk Institute have clarified the response pathway to steroid hormone brassinolide, a key element in plant growth. The study reveals that BES1 is activated in the nucleus after BIN2 inhibition, leading to gene activation and promoting plant growth.
Researchers at North Carolina State University discovered that plants respond similarly to signals from both beneficial rhizobia and parasitic root-knot nematodes. This response involves rapid changes in the distribution of the plant's cytoskeleton, leading to growth changes such as nodules or galls.
Researchers at the University of Utah have identified a novel gene, BYPASS1, that regulates root-to-shoot communication and controls plant architecture. The study reveals that roots produce a growth-inhibiting substance that affects shoot development, providing new insights into plant signaling.
Scientists at Cornell University discovered a key player in plant immunity, the salicylic acid-binding protein 2 (SABP2) gene, which enables plants to fight off diseases by inducing programmed cell death. This finding offers new strategies for boosting natural defenses and reducing pesticide use.
Researchers have identified a system in a mutant arabidopsis that signals cells to pause during stressful situations, allowing plants to regulate themselves and adjust before growth resumes. This discovery may lead to breeding plants with improved stress handling techniques and enhanced drought tolerance.
Researchers have identified gamma-amino butyric acid (GABA) as a key signaling molecule that triggers plant reproduction and guides the growth of pollen tubes. In contrast, mutants with deficient GABA degradation produce a massive increase in the chemical signal, overwhelming the pollen tubes and disrupting their guidance.
Scientists identify enzyme in plants that triggers S1P production, a molecule involved in regulating cell proliferation and death. The discovery sheds light on plant's ability to withstand drought and may lead to development of crop varieties with higher yields and greater resistance.
The study shows that glucose functions as a signal compound affecting plant growth, germination, and flowering. This discovery may lead to new research on human development disorders like diabetes and obesity.
Insects like corn earworms intercept plant chemical signals to produce detoxifying enzymes that neutralize toxins. This allows them to mount their own defenses and counterattack plants' defensive systems.
A University of Toronto professor has identified a key protein in the fight against plant disease, which could lead to genetically engineered crops resistant to various diseases. The discovery was made using a mutant strain of weed that lacks this protein, revealing its role in triggering systemic acquired resistance.
