Optical-sensors improve nitrogen utilization efficiency
       Nitrogen use efficiency (NUE) for cereal crops grown around the world is low with an estimated value of 33%. This means that a considerable amount of nitrogen (N) is not recovered in the grain. As a result, several independent studies have been conducted to evaluate active optical sensors as an approach for N management. These studies reported benefits that range from N saving to higher NUE and sustaining grain yield in comparison to conventional methods of N management. This work reviewed and documented the extent to which the use of active optical sensors impacted winter wheat grain yield and NUE. In particular, the amount of N saved, NUE, and grain yield were reviewed and results presented by N management approach and region.

Soluble Starch Synthase Enzymes in Cereals
Starch is synthesized by different enzymes, but starch structure and amount are mainly determined by the activities of starch synthase enzymes (SS) with the involvement of starch branching enzymes (SBEs) and debranching enzymes (DBEs).

Signaling Pathways Involving Epigallocatechin Gallate
Epigallocatechin gallate (EGCG) is the main bioactive component of catechins predominantly present in various types of tea. EGCG is well known for a wide spectrum of biological activities as an anti-oxidative, anti-inflammatory, and anti-tumor agent. The effect of EGCG on cell death mechanisms via the induction of apoptosis, necrosis, and autophagy has been documented.

Asphyxia in Newborn Canines
Morphological variability in canines is associated with the mother’s size and weight, which likely affects the birth weight of the puppies and their metabolic status. Identifying physio-metabolic alterations in the blood from the umbilical vein to evaluate the concentration of gases, glucose, lactate, calcium, hematocrit levels, and blood pH of newborn puppies will make it possible to determine the risk of complications due to intrauterine asphyxia.

Trends in Organic Vegetable Crop Production
Organic farming is a holistic production management system that promotes and enhances agroecosystem health, including biodiversity, biological cycles and soil biological activity, and consequently, it is an efficient and promising approach for sustainable agriculture within a circular and green economy. There has been a rise in the consumption of organic vegetables in the last years because of their organoleptic properties, higher nutritive value and lower risk of chemical residues harmful to health. The scientific evidence regarding the use of the major elements responsible for organic vegetable crop production indicates plant material, soil management and crop nutrition, soil disinfection, crop management and pest, disease and weed management.

Calcium Nutrition of Broilers
Calcium (Ca) is essential for the skeletal growth and a plethora of other functions in broilers. Over 80% of Ca in broiler diets is supplied by inorganic Ca sources among which limestone is the predominant Ca supplement. Currently, considerable attention is being directed towards the use of digestible Ca in poultry feed formulations.The specific aim of the present overview was to highlight the recent advances in the measurement of ileal Ca digestibility of Ca sources and digestible Ca requirement of broilers.

Plant Growth Promoting Microorganisms in Soilless Systems
Soilless systems, such as hydroponics and aquaponics, are gaining popularity as a sustainable alternative to traditional soil-based agriculture, aiming at maximizing plant productivity while minimizing resource use. Plant growth-promoting microorganisms (PGPM) have emerged as a promising solution to overcome these issues. Bacillus, Pseudomonas, and Azospirillum are the most extensively studied genera for their effectiveness as growth promoters, inducing changes in root architecture morphology. Furthermore, PGPM inoculation, either alone or in synergy, can reverse the effects of nutrient deficiency and salt stress. The genera Pseudomonas and Trichoderma were recognized for their solid antagonistic traits, which make them highly effective biocontrol agents in hydroponic systems. The findings indicate their ability to significantly reduce disease severity index (DSI) through mycoparasitism, antibiosis, and induced systemic resistance. In aquaponic systems, the inoculation with Bacillus subtilis and Azospirillum brasilense demonstrated increased dissolved oxygen, improving water quality parameters and benefiting plant and fish growth and metabolism.

Polycomb Repressive Complex 2
Polycomb repressive complex 2 (PRC2) represents a group of evolutionarily conserved multi-subunit complexes that repress gene transcription by introducing trimethylation of lysine 27 on histone 3 (H3K27me3). PRC2 activity is of key importance for cell identity specification and developmental phase transitions in animals and plants.

Genomic Selection for Wheat Quality
Selection for wheat (Triticum aestivum L.) grain quality is often costly and time-consuming since it requires extensive phenotyping in the last phases of development of new lines and cultivars. The development of high-throughput genotyping in the last decade enabled reliable and rapid predictions of breeding values based only on marker information. Genomic selection (GS) is a method that enables the prediction of breeding values of individuals by simultaneously incorporating all available marker information into a model. The success of GS depends on the obtained prediction accuracy, which is influenced by various molecular, genetic, and phenotypic factors, as well as the factors of the selected statistical model.

Latin American Cattle Ranching Sustainability Debate
The significance of Latin America (LA) in the global food supply is large and prominent. The livestock sector at this time faces social-ecological challenges that will be accentuated in the future and will be incredibly challenging for small and medium producers. It is important to understand the role of LA cattle ranching in the current sustainability debate. In addition, researchers identified the main components of cattle ranching social-ecological systems and evaluated the institutional and ecological interactions of livestock studies by identifying spatial and temporal scales. The complexity and dynamism of cattle ranching in LA make it necessary to address sustainable planning from a systemic approach to guide viable transformations through spatial scales.

Innate Immune Cells in the Chicken Intestine
The chicken intestinal epithelium is a monolayer consisting of various cell types. Intercellular junctional complexes, tight junctions, present between the intestinal epithelial cells maintain the gut barrier integrity. Tight junctions hold the intestinal epithelial cells together to prevent the entry of enteric pathogens and thus maintain gut homeostasis. In addition to the gut microbiota, also intestinal epithelial cells inhibit the entry of pathogens for example by producing a mucus layer. In addtion to this physical barreier, also soluble factors suc a antimicrobial compunds play a role in the defence against pathogens. When all these defense mechanism are not sufficient in protecting the host, the cells of the intestinal innate immune system are activated. Properties and function of these cells are the subject of this entry.

Atypical Centriolar Composition and Internal Fertilization in Fish
Internal sperm structures， the centriole has an ancient and evolutionarily conserved canonical structure with signature 9-fold, radially symmetric microtubules that form the cell’s centrosomes, cilia, and flagella. Most animal spermatozoa have two centrioles, one of which forms the spermatozoan flagellum. Both are delivered to the egg and constitute the embryo’s first two centrosomes. The spermatozoa of mammals and insects only have one recognizable centriole with a canonical structure.
