Nitrogen (N) transformation inhibitors have been widely recognized as a promising strategy to enhance crop productivity and mitigate N losses. However, the effectiveness of individual or combined inhibitors can vary significantly across different agroecosystems. Using meta-analysis and cost-benefit analysis (CBA), we synthesized findings from 41 peer-reviewed studies (285 observations) globally to evaluate the efficacy of urease inhibitors (UIs), nitrification inhibitors (NIs), and combined inhibitors (UINIs).

Oxylipin signalling is central in biology, mediating processes such as cellular homeostasis, inflammation and molecular signalling. It may also facilitate inter-partner communication in the cnidarian-dinoflagellate symbiosis, though this aspect remains understudied. In this study, four oxylipin receptors were characterised using immunohistochemistry and immunoblotting in the sea anemone Exaiptasia diaphana ('Aiptasia'): Prostaglandin E2 receptor 2 (EP2) and 4 (EP4), Transient Receptor Potential cation channel A1 (TRPA1) and Glutamate Receptor Ionotropic, Kainate 2 (GRIK2).

Background: Conifers, mainly of the genus Pinus, have invaded natural and productive landscapes worldwide. Controlling dense conifer invasions is challenging and requires both effective initial control methods and long-term site management to prevent re-invasion. Broadcast aerial herbicide application is often the preferred treatment method for dense infestations of pines with high rates of complex herbicide mixtures used.

Plant proteins are increasingly incorporated into food products to enhance their nutritional value. However, little is known about how this alters the textural perceptions of such products. This study investigated the substitution of up to 35% wheat flour with pea protein isolate (PPI) into pasta sheets to determine how this influenced texture.

The transition from breastmilk to solid foods (weaning) is a decisive stage for the development of the colonic microbiota. However, little is known about how complementary foods influence the composition and function of the colonic microbiota in infants. This systematic review collected evidence of the effect of individual foods on the fecal microbiota of weaning infants (4-12 months old) using five databases: PubMed, CENTRAL, Scopus, Web of Science, and ScienceDirect.

The rise in the global population has increased the demand for dietary food protein. Strategies to maximize agricultural and livestock outputs could strain land and freshwater supply and contribute to substantial negative environmental impacts. Consequently, there has been an emphasis on identifying alternative sources of edible proteins that are more sustainable, sustainable, ethical, and healthy.

China.

Kiwifruit (Actinidia chinensis), a recently commercialized horticultural crop, is rich in various nutrient compounds. However, the regulatory networks controlling the dynamic changes in key metabolites among different tissues remain largely unknown. Here, high-resolution spatiotemporal datasets obtained by ultraperformance liquid chromatography-tandem mass spectrometry methodology and RNA-seq were employed to investigate the dynamic changes in the metabolic and transcriptional landscape of major kiwifruit tissues across different developmental stages, including from fruit skin, outer pericarp, inner pericarp, and fruit core.

This work investigated the effects of superabsorbent polymers (SAPs) as pore-forming agent and palm oil fuel ash (POFA) as sand replacement (0-100 % by weight) on the strength, economic feasibility, and CO emissions for lightweight concrete production. The product properties were compared with the traditional aerated concrete (with aluminum powder), which aimed to shed light on the use of SAPs and POFA for manufacturing a more sustainable lightweight concrete. The use of POFA to replace sand increased the cost of production by approximately 1-7% and CO emissions by approximately 3-12 % due primarily to the transportation of the POFA from the oil palm fuel power plant, which could be avoided if produced on site of or near the power plant.

Sustainable management of potato tuber moth in storages using entomopathogenic fungi and an ectoparasitic mite.

Pest Manag Sci

December 2024

State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, P. R. China.

Background: The potato tuber moth (PTM), Phthorimaea operculella, is an economically important pest of potato crops worldwide. So far, the application of chemical pesticides is the major measure to manage PTM, but it induces serious deleterious impacts on the environment and human health. Here, we screened the entomopathogenic fungi that are lethal to PTM, and tested their sublethal impacts on PTM development, mortality, and reproduction as well as that of ectoparasitic mite Pyemotes zhonghuajia, a natural enemy of PTM.

Achieving High Protein Quality Is a Challenge in Vegan Diets: A Narrative Review.

Nutr Rev

December 2024

Sustainable Nutrition Initiative, Riddet Institute, Massey University, Palmerston North, 4410, New Zealand.

The transition toward plant-based (PB) diets has gained attention as a plausible step toward achieving sustainable and healthy dietary goals. However, the complete elimination of all animal-sourced foods from the diet (ie, a vegan diet) may have nutritional ramifications that warrant close examination. Two such concerns are the adequacy and bioavailability of amino acids (AAs) from plant-sourced foods and the consequences for older vegan populations who have elevated AA requirements.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Article Synopsis
  • Blueberries have a variety of anthocyanins that give them their blue color, and some types can produce more stable acylated anthocyanins, making them a focus for breeding.
  • This study focused on a specific gene, VcAAT1a, which was found to effectively produce different acylated anthocyanins in various plant systems.
  • The research identified that VcAAT1a only uses acetyl CoA as an acyl donor, and its promoter is activated by certain transcription factors, providing insight into how anthocyanin production is regulated in blueberries.

Article Synopsis
  • The study assessed gas-exchange characteristics, pigment contents, and photosynthetic traits in three rice cultivars (JR3015, Wufengyou3015, Jifengyou3015) using mechanistic models.
  • The results showed that while chlorophyll content varied, the maximum electron transport rate did not, with JR3015 having lower chlorophyll but better electron transport efficiency due to higher eigen-absorption cross-sections and shorter pigment molecule lifetimes.
  • Despite these traits, JR3015 displayed the lowest photosynthetic efficiency and net photosynthetic rate compared to the other cultivars, highlighting important considerations for selecting rice based on photosynthesis.

Article Synopsis
  • Nonstructural carbohydrates (NSC) in leaves relate to photosynthesis and respiration, influencing plant strategies.
  • A study involving 114 species showed that total NSC concentrations varied widely but generally didn't correlate with leaf gas exchange or economic traits.
  • However, species with higher photosynthesis had shorter NSC residence times, indicating that daily carbon gain is mainly exported rather than stored.
