Epigenetic modification of DNA and histones is a conserved gene regulatory mechanism and plays critical roles in diverse aspects of biological processes, ranging from genome defense and imprinting to development and physiology. In recent years, emerging studies have revealed the interplay between signaling transduction pathways, epigenetic modifications, and chromatin cascades. Specifically, histone acetylation and deacetylation dictate plant responses to environmental cues by modulating chromatin dynamics to regulate downstream gene expression as signaling outputs. In this review, we summarize current understandings of the link between plant signaling pathways and epigenetic modifications with a focus on histone acetylation and deacetylation. © The Author(s) 2020.

METHODS The characteristics of Mincle signaling expression in CD patients and experimental colitis were examined. The functional role of Mincle signaling in the intestine was addressed in experimental colitis models in vivo by using Mincle knock out (Mincle-/-) mice. In addition, neutralising anti-Mincle antibody, downstream spleen tyrosine kinase (Syk) inhibitor and Mincle pharmacologic agonist were used to study the Mincle signaling in intestine. Bone marrow-derived macrophages were collected from mice and used to further verify the effect of Mincle signaling in macrophages. RESULTS This study has shown that Mincle signaling was significantly elevated in active human CD and experimental colitis, and macrophages were the principal leukocyte subset that up-regulate Mincle signaling.p.com.BACKGROUND AND AIMS Manganese (Mn) deficiency in barley is a global problem. It is difficult to detect in the early stages of symptom development and is commonly pre-emptively corrected by Mn foliar sprays that can be costly. Landraces adapted to marginal lands around the world represent a genetic resource for potential sustainability traits including mineral use efficiency. This research aims to confirm novel Mn use efficiency traits from the Scottish landrace Bere and use an association mapping approach to identify genetic loci associated with the trait. METHODS A hydroponic system was developed to identify and characterise the Mn deficiency tolerance traits in a collection of landraces, including a large number of Scottish Bere barleys, a group of 6-rowed heritage landraces grown in the highlands and islands of Scotland. link2 Measuring chlorophyll fluorescence, the effect of Mn deficiency was identified in the early stages of development.

AMH signals through its own dedicated type II receptor, Anti-Müllerian Hormone Receptor Type II (AMHR2), providing an exclusive ligand-receptor pair within the broader TGFβ family. In this study, we used previous structural information to derive a model of AMH bound to AMHR2 to guide mutagenesis studies to identify receptor residues important for AMH signaling. Non-conserved mutations were introduced in AMHR2 and characterized in an AMH responsive cell-based luciferase assay and Native PAGE. Collectively, our results identified several residues important for AMH signaling within the putative ligand binding interface of AMHR2. Our results show that AMH engages AMHR2 at a similar interface to how Activin and BMP class ligands bind the type II receptor, ACVR2B, however, there are significant molecular differences at the ligand interface of these two receptors, where ACVR2B is mostly hydrophobic and AMHR2 is predominately charged. Overall, this study shows that while the location of ligand binding on the receptor is similar to ACVR2A, ACVR2B, and BMPR2; AMHR2 uses unique ligand-receptor interactions to impart specificity for AMH. © Endocrine Society 2020.Hypoparathyroidism during pregnancy is a very rare endocrine disorder. The majority of cases are postsurgical (75%). Managing pregnant or nursing women with hypoparathyroidism is challenging due to complications arising from either under- or overtreatment, including premature delivery or fetal death, abortion, stillbirth, perinatal death and neonatal tetany. Specific adaptations are needed within each time period to meet the fetal, neonatal and maternal calcium requirements. A systematic search was performed on PubMed using the search terms "pregnancy" and "hypoparathyroidism". Included were articles published in English between 1 January 1966 and 1 January 2018. We provide an overview of all published cases (n=43) of hypoparathyroidism in pregnancy, including a case report of a 29-year-old pregnant woman who underwent a total thyroidectomy before her current pregnancy because of a therapy-resistant Graves' disease. The procedure was complicated by postsurgical hypoparathyroidism. She carried out the pregnancy to term with minor complaints of paresthesia and muscle cramps. Furthermore we discuss treatment, complications and follow-up of hypoparathyroidism in pregnancy. Treatment of hypoparathyroidism in pregnancy should still be individualized, depending on the patient's complaints and serum levels of calcium, which should be maintained in the lower normal range of 2.15-2.55 mmol/l according to literature. We recommend monitoring calcium levels every three to four weeks throughout pregnancy, within one week postpartum and monthly during lactation to ensure normocalcemia. © Endocrine Society 2020.

We studied light-induced photomorphogenic development in the presence of the BR-biosynthesis inhibitor, brassinazole (Brz). Hook opening was inhibited in the presence of Brz; this inhibition was reversed in the presence of brassinolide. Hook opening was accompanied by cell expansion on the inner (concave) side of the hook. This cell expansion was inhibited in the presence of Brz, but was restored upon addition of brassinolide. We then evaluated light-induced organ-specific expression of three BR biosynthesis genes, DWF4, BR6ox1, BR6ox2, and a BR-responsive gene, SAUR-AC1, during photomorphogenesis of Arabidopsis. Expression of these genes was induced, particularly in the hook region, in response to illumination. The induction peaked after 3 h light exposure and preceded hook opening. Phytochrome-deficient mutants, hy1, hy2, and phyAphyB, and a light-signaling mutant, hy5, were defective in light-induced expression of BR6ox1, BR6ox2 and SAUR-AC1. Light induced both expression of BR6ox genes and petiole development. Petiole development was inhibited in the presence of Brz. Our results largely contradict the early view that BRs are negative regulators of photomorphogenesis. Our data collectively suggest that light activates expression of BR biosynthesis genes in the hook region via a phytochrome-signaling pathway and HY5, and that BR biosynthesis is essential for hook opening and petiole development during photomorphogenesis. © The Author(s) 2020.

But the relative importance of these explanations and, especially, their interplay and possible synthesis remain largely elusive. link3 Integrating diversification analyses, null models, and GIS, I study avian richness across regions and elevations of the New World. My results reveal that even though the three explanations are differentially important (with ecological limits playing the dominant role), each contributes uniquely to the formation of richness gradients. Further, my results reveal the likely interplay between the explanations. They indicate that ecological limits hinder the diversification process, such that the accumulation of species within a region gradually slows down over time. Yet, it does not seem to converge toward a hard ceiling on regional richness. Instead, species-rich regions show suppressed, but continued, diversification, coupled with signatures of possible competition (esp. Neotropical lowlands). Conversely, species-poor, newly-colonized regions show fast diversification and weak to no signs of competition (esp. Nearctic highlands). These results held across five families of birds, across grid cells, biomes, and elevations. Together, my findings begin to illuminate the rich, yet highly consistent, interplay of the mechanisms that together shape richness gradients in the New World, including the most species-rich biodiversity hotspots on the planet, the Andes and the Amazon. © The Author(s) 2020.

Negative aspects of gastrointestinal (GI) function, integrity and permeability also occur. High intensity sweeteners can ameliorate the negative effects of heat stress (HS) by increasing GI glucagon-like peptide (GLP)-2 production while capsicum oleoresin has been shown to reduce inflammatory response. Effects of an artificial high intensity sweetener and capsicum oleoresin (CAPS-SUC; TakTik X-Hit, Pancosma, Switzerland) on growth performance of pigs were examined. Forty-eight pigs (12 weeks of age, 43.2 kg ± 4.3 kg) were assigned to six treatments thermoneutral conditions (21°C ± 1.1°C; 40% to 70% relative humidity) fed ad libitum with (TN+) or without supplement (TN-), heat stress (35°C ± 1°C; 20% to 40% relative humidity) fed ad libitum with (HS+) or without supplement (HS-), and thermoneutral conditions pair-fed to HS intake with (PFTN+) or without supplement (PFTN-). Sntrations as well as monocyte count increased in HS compared to PFTN (P less then 0.04) but did not differ from TN and likely linked to altered feed intake. CAPS-SUC increased basophil count (P less then 0.02), irrespective of environment. Ileal villus height tended to decrease during HS and PFTN compared to TN (P less then 0.08), indicating an effect of intake. Overall, CAPS-SUC supplementation increased pig feed efficiency and may improve immune response. © The Author(s) 2020.
