Hybridization with transcription factor AREB increases drought resistance in elite soybean cultivars

Rectangular horizontal photo. Plantation a bit blurred. Thin, tall branches, leaves that look like pods hanging from the branches. The plants look dry, but this may be due to lighting. In the background, strong and diffuse sun. The whole image is very yellowish and with strong shadows.

Soybean cultivation requires attention due to its susceptibility to drought. The introgression of the AtAREB1 transgene into the LS93-0375 and BMX Desafio RR elite cultivars conferred a better physiological performance to the genotypes, proving to be an effective mechanism of genetic engineering for the reduction of the effects of water deficit.

Brusone: Wheat blast disease requires chemical control management and increased genetic resistance of crops

Composition. 8 images arranged horizontally 4x4. The top ones are close-up shots of long dark green leaves with straight light green lines and black or yellowish spots. The bottom ones are lime green wheat clumps, some have spots. The clumps are half oval half triangular and grow upwards from the stem. They also have small, long, thin leaves.

A fungal disease that attacks wheat cultivation threatens world food security by compromising up to 100% of infected crops. Research points to the importance of making crops less susceptible by combining chemical control and genetic resistance protocols to increase productivity and reduce losses. Read More →

Analysis brings a retrospect of more than 20 years of hipmagnesemia cases in cows

Vertical horizontal photo. A black-haired cow with two calves on her side. They are in a very green pasture.

When magnesium levels in the blood are low, hypomagnesemia occurs. The disease occurs in ruminants and is responsible for important economic losses in beef herds in Argentina. The analysis of 20 years of cases of this disease demonstrates similarities in patterns of seasonality, management and associated climatic conditions, dietary factors, among others. Read More →

Hybrid grape seeds can inhibit the initial phase of some types of cancer

Hybrid grapes have chemopreventive and antioxidant properties, especially in green seeds, which showed higher content of chemical compounds that contribute to such properties compared to more mature grapes. The discovery opens possibilities for future studies to isolate the active molecule and further develop pharmaceuticals. Read More →

Researchers use drones to identify nematodes

Soybean is one of the main species of cultivated plants in the world, having an important role in the food sector and as raw material. Several types of stressors cause losses in soybean, such as nematodes. Using drones, the study determined the best spectral band for the detection of two types of nematodes. Read More →

Evaluation of 42 rootstocks behavior in Citriculture

Citrus culture is the cultivation of citrus fruits, especially orange and lime. This practice is one of the most important sectors of agribusiness in Brazil and generally utilizes the rootstock technique. The analysis evaluates the behavior of 42 rootstocks of “Valência Late” orange trees during the seedling. The results point to some possible alternatives for new rootstocks that will be field tested.

Charcoal from slaughterhouse waste and maravalha are a sustainable alternative for domestic use

Photograph of 8 coal samples with different treatments on a white background.

Considering the increase in effluent generation in poultry slaughterhouses in recent years, as a result of the growing demand for chicken meat around the world, combined with the need to develop new forms of renewable energy it was possible to produce charcoal for barbecue using sludge from poultry slaughterhouse and shavings of Pinus spp. Read More →

Genomic monitoring of Holstein cattle as a strategy in dairy production

Dairy production is one of the most important sectors of the Uruguayan economy. The genetic disorders of the “Holstein” breed cause production problems, compromising the sustainability of the milk production. The genomic monitoring of carrier animals is necessary to avoid the spread of lethal and semi-lethal alleles and to reduce the economic losses to dairy farming. Read More →

CEVAP: ready for the 21st century

CEVAP has been working diligently since its founding in translational research with animal venoms. During this 30-year journey, a scientific journal was launched, two biopharmaceuticals were developed and numerous professionals, academic or not, were trained. Now, CEVAP is heading towards its future looking towards the creation of a factory aiming at scientific research. Read More →
