Optimal fertilization thanks to sensor and cloud

A new nitrate sensor developed by Ruhr-University Bochum can analyze one drop of plant juice in seconds to determine optimal fertilization levels, resulting in improved crop yields and reduced waste. The sensor is linked to a cloud-based system that estimates regional fertilizer demand and provides farmers with real-time data.

How plants see light

A team of scientists has identified two proteins, PCH1 and PCHL, that regulate the activity of phytochrome B, a key photoreceptor protein in plants. This discovery allows plants to adapt their light sensitivity to different environmental conditions, enabling them to optimize photosynthesis and growth.

Viral probe gives ringside view of cell-to-cell combat

Researchers used a plant virus to study how plants defend themselves against invading pathogens, revealing key receptor proteins that regulate RNA interference. The findings also identified a suppressor protein named C4 used by the virus to disarm the plant's defence mechanism.

Agricultural parasite takes control of host plant's genes

Researchers discovered that a parasitic plant called Dodder can silence the expression of genes in its host plants, including those involved in defense against parasites. By targeting specific regions of the gene sequence, Dodder regulates the flow of nutrients to itself while preventing the host from producing defensive proteins.

Male trout are now real males again

Researchers at the University of Southern Denmark found that widespread feminization among male brown trout in Danish streams had completely disappeared between 2004 and 2016. The improvement was attributed to better wastewater treatment practices, particularly the connection to municipal wastewater treatment plants.

High yield, protein with soybean gene

Researchers have successfully bred soybeans with both high yields and high protein levels, addressing a long-standing challenge in plant breeding. The genetic findings suggest that a specific gene on chromosome 15 can increase protein concentration without significantly decreasing yields.

Pest resistance to biotech crops surging

A global assessment reveals that genetically engineered crops producing insect-killing proteins from Bacillus thuringiensis have led to a fivefold increase in pest resistance cases over the past decade. However, some pests remain suppressed due to factors such as recessive inheritance of resistance and abundant refuges.

Quorn protein on par with animal sources

A new study by the University of Exeter suggests that Quorn protein may be as effective as animal-based proteins in building muscle. The research compared Mycoprotein, a fungi-based protein source found in Quorn foods, to milk protein and found equivalent bioavailability.

Protein restricts sap uptake by aphids

Researchers at Umea University have discovered a plant protein that limits aphid feeding behavior, resulting in reduced sap ingestion and fewer offspring on resistant plants. The protein is thought to occlude the narrow food canal of the aphid, providing a new avenue for developing more sustainable crop resistance.

New study deems dairy 'excellent' source of protein for children

Researchers at University of Illinois conducted a study to calculate protein scores for eight sources of protein derived from both plants and animals. The digestible indispensable amino acid score (DIAAS) method was used, which showed all dairy proteins met Food and Agriculture Organization standards as 'excellent/high' quality sources.

Soy protein concentrate can replace animal proteins in weanling pig diets

Researchers found that soy protein concentrate (SPC) ground to three particle sizes showed improved digestibility of crude protein and amino acids compared to traditional protein sources. The results indicate that SPC can be used as an alternative to animal proteins in weanling pig diets without negative effects on growth performance.
