Summary: Biostimulants have been widely used in agriculture as growth enhancers and stress protectants. This study investigates how the modulation of nitrogen metabolites and potassium levels by biostimulants can mediate physiological mechanisms in response to salt or osmotic stress. Reshaping of amino acid metabolism is found to play a key role in coordinating ion homeostasis, osmotic adjustment, and scavenging of reactive oxygen species under increased osmotic stress. The Superfifty biostimulant shows potential for untangling nitrogen metabolism dynamics in response to salinity and osmotic stress.

Summary: The use of the biostimulant ERANTHIS, based on seaweed and yeast extracts, was tested on tomato plants grown under mild water-stress conditions, showing lower stress-related substances and ROS scavenger enzyme activity, as well as higher stem water potential and photosynthetic pigment levels compared to untreated plants. These results suggest that ERANTHIS may mitigate water stress effects on tomato plants.

Summary: Poultry, especially broiler meat, is considered the main source of human campylobacteriosis. This study aimed to test a phlorotannin extract from brown seaweed as a potential control strategy against Campylobacter in broilers. In vitro tests showed bactericidal activity against various strains of Campylobacter. However, in vivo trials and experiments in commercial broiler flocks did not show significant effects on Campylobacter colonization or growth parameters when the extract was added to the feed. Further studies are needed to assess the presence of active polyphenols in the ceca.

Summary: Seaweeds, primitive plants and macroalgae, typically grow in shallow water areas such as backwaters, estuaries, and seas. They attach to coral reefs, rocks, and other substrata. Researchers collected seaweeds from the Kanyakumari region and processed them to extract methanol using the Saccharification method. The highest yield of methanol (51.2%) was obtained with a substrate concentration of 15% and a time duration of approximately 48 hours. The study focused on producing methanol from a high concentration and choice of seaweed (Sargassum wightii).

Summary: This study found that phlorotannins from Ascophyllum nodosum and Fucus vesiculosus significantly reduced blood sugar, cholesterol, and triglyceride levels in rats with hyperlipidemia. It also increased insulin and high-density lipoprotein cholesterol levels while promoting lipase activity. Moreover, phlorotannins reduced adipocyte size, decreased inflammatory factors, and increased antioxidant enzyme activity. These results suggest that Ascophyllum nodosum and Fucus vesiculosus could be potential sources of anti-hyperlipidemia drugs and functional foods.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study investigates the agroclimatic requirements of Prunus species cultivars growing in warm areas using Partial Least Squares regression. The findings reveal that the chilling and heat requirements of the cultivars appear discontinuous, with overlaps or transition periods between the two phases. The warm mean temperatures occurring during the chilling period are the main determinant of the flowering of the studied cultivars.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
