The pivotal role of CBF/DREB1 transcriptional factors in Triticeae crops involved in the abiotic stress response has been highlighted. The CBFs represent an important hub in the ICE-CBF-COR pathway, which is one of the most relevant mechanisms capable of activating the adaptive response to cold and drought in wheat, barley, and rye. Understanding the intricate mechanisms and regulation of the cluster of CBF genes harbored by the homoeologous chromosome group 5 entails significant potential for the genetic improvement of small grain cereals. Triticeae crops seem to share common mechanisms characterized, however, by some peculiar aspects of the response to stress, highlighting a combined landscape of single-nucleotide variants and copy number variation involving CBF members of subgroup IV. Moreover, while chromosome 5 ploidy appears to confer species-specific levels of resistance, an important involvement of the ICE factor might explain the greater tolerance of rye. By unraveling the genetic basis of abiotic stress tolerance, researchers can develop resilient varieties better equipped to withstand extreme environmental conditions. Hence, advancing our knowledge of CBFs and their interactions represents a promising avenue for improving crop resilience and food security.

Oxytocin (OT) is a neurohormone involved early in neurodevelopment and is implicated in multiple functions, including sensory modulation. Evidence of such modulation has been observed for different sensory modalities in both healthy and pathological conditions. This review summarizes the pleiotropic modulation that OT can exercise on an often overlooked sensory system: thermosensation. This system allows us to sense temperature variations and compensate for the variation to maintain a stable core body temperature. Oxytocin modulates autonomic and behavioral mechanisms underlying thermoregulation at both central and peripheral levels. Hyposensitivity or hypersensitivity for different sensory modalities, including thermosensitivity, is a common feature in autism spectrum disorder (ASD), recapitulated in several ASD mouse models. These sensory dysregulations occur early in post-natal development and are correlated with dysregulation of the oxytocinergic system. In this study, we discussed the potential link between thermosensory atypia and the dysregulation of the oxytocinergic system in ASD.

Beginning with Innocent III's pontificate, participation in the crusades became increasingly interpreted as imitatio Christi patientis. Innocent III's crusade theology was revived by later pontiffs and became ingrained in the collective imagination through preaching. This article shows how Dante draws on thirteenth-century crusade theology in his depiction of the cross of Mars, with special attention paid to imitatio Christi. Dante's rendering of his inner sacrifice (Par. xiv, 88–93) foreshadows the apparition of the cross and appears to have been influenced by the imagery of the crusader's vow as found in contemporary ecclesiastical documents. In these texts, crusaders are frequently depicted as participating in an inner sacrifice prompted by the fire of caritas that recalls Christ's own sacrifice. Reading Paradisoxiv-xv in light of this context – and with an awareness of the significance of Cacciaguida's placement in the same heaven – allows us to explore Dante's self-representation as a miles Christi.

Lavandin (Lavandula x intermedia) belongs to the Lamiaceae family and is a shrub cultivated in the Mediterranean region for essential oils used to produce cosmetic, aromatherapy, and pharmaceutical ingredients. Nowadays, interest in plant biostimulants is rising due to their ability to increase biomass production in a sustainable way. The scope of the present study was to assess the effects of two plant biostimulants, one based on hydrolyzed proteins (FITOSIM®) and one based on seaweed extracts (FITOSTIM ALGA®), on the cultivar Grosso for two consecutive years in three different farms, located in the Italian Tuscan-Emilian Apennine Mountains. A difference in the efficiency of treatments among farms was shown, probably due to the plant age. In 2020, FITOSTIM ALGA® increased inflorescence fresh weights (+35%), while FITOSTIM® and FITOSTIM ALGA® enhanced stem and total fresh weights (+23% and +22%, respectively) compared to the untreated control. In 2021, both treatments enhanced the fresh and dry weights of inflorescence (+47% and +38%, respectively), while FITOSTIM ALGA® also improved the total plant dry weights (+34%). The plant biostimulants did not affect the chemical composition of essential oils. Our results indicate plant biostimulants as a supplement for sustainable management practices, enhancing Lavandin’s performance in mountainous agricultural areas.

Introduction Studies on large samples agree on the negative impact of maternal perinatal depression (PD) on child’s cognitive development. Early experience with insensitive maternal interactions appears to be predictive of poorer cognitive functioning. These children present a higher risk for the onset of socioemotional development, nutrition, growth and sleep disorders. Research on Covid-19 pandemic suggests that families, particularly mothers, may be at increased risk of psychological distress. Objectives This study evaluates the effect of perinatal depression on child development and the impact of distress caused by the Covid-19 pandemic. Methods We designed a case-control study comparing, during Covid-19 pandemic, a group-A of children of mothers with PD (n=19), with a group-B of children of healthy mothers (n=21). The age of the children recruited was 4-35 months. Participating mothers underwent DP3-Interview and the socioemotional and adaptive-behavior Bayley’s scales by telephone and completed an online survey (IES-R). Results We found significantly lower scores on the Bayley socioemotional scale and in all the DP3-scales, in group-A. There is an inversely proportional correlation between the age of these children and overall development score of the DP3. On the IES-R scale, the medium scores in both groups show no psychological distress as a consequence of the Covid-19 pandemic, although mothers with PD show borderline total scores and higher hyperarousal scale values. Conclusions This study confirms that PD is a risk factor for the onset of disorders in all areas of the child’s development. Mothers with PD are less likely to manage psychological distress secondary to the pandemic. Disclosure No significant relationships.

Introduction Perinatal period is characterized by a broad range of physical, psychological and relational changes. Maternal perinatal depression (PD) is defined as an episode of major depression with the onset from pregnancy to the first year after delivery. Depressive symptoms influence the earlier mother-child interaction and impact on child cognitive, affective and behavioral development. Objectives Purpose of our study was to evaluate the consequences of PD on sleep-wake patterns in the early stages of infant development. We aim to investigate the presence of poor sleep in infants/ toddlers and also to identify differences in sleep ecology variables. Methods We enrolled, from December 2019 to September 2020, a clinical sample of children born from women with PD (N=19, m.a.=13,7, SD= 7,6) and a healthy control group (N=21, m.a.=15,5, SD=5,43). Infant sleep data were obtained from the Brief Infant Sleep Questionnaire (BISQ). Poor sleepers were defined by the following criteria: >3 night wakings, nocturnal wakefulness >1 hr or total sleep duration

Prader-Willi syndrome (PWS) is a genetic neurodevelopmental disorder that presents with hypotonia and respiratory distress in neonates. The Necdin-deficient mouse is the only model that reproduces the respiratory phenotype of PWS (central apnea and blunted response to respiratory challenges). Here, we report that Necdin deletion disturbs the migration of serotonin (5-HT) neuronal precursors, leading to altered global serotonergic neuroarchitecture and increased spontaneous firing of 5-HT neurons. We show an increased expression and activity of 5-HT Transporter (SERT/Slc6a4) in 5-HT neurons leading to an increase of 5-HT uptake. In Necdin-KO pups, the genetic deletion of Slc6a4 or treatment with Fluoxetine, a 5-HT reuptake inhibitor, restored normal breathing. Unexpectedly, Fluoxetine administration was associated with respiratory side effects in wild-type animals. Overall, our results demonstrate that an increase of SERT activity is sufficient to cause the apneas in Necdin-KO pups, and that fluoxetine may offer therapeutic benefits to PWS patients with respiratory complications.

Aphidius erviis an endophagous braconid, parasitoid of the pea aphid,Acyrthosiphon pisum. A. erviteratocytes, deriving from the dissociation of the embryonic serosa, synthesize and release two major proteins into the host haemocoel. The gene of one of these proteins has been cloned and characterized. This gene codes for a 15.8 kDa protein belonging to the fatty acid binding protein (FABP) family, namedAe-FABP (A. ervi-FABP). It is abundantly present in the host haemolymph when the parasitoid larva attains its maximum growth rate. The recombinantAe-FABP binds to fatty acidsin vitro, showing a high affinity to C14–C18 saturated fatty acids and to oleic and arachidonic acid. The possible nutritional role for the parasitoid larva ofAe-FABP is discussed. [ABSTRACT FROM AUTHOR]

Parasitism by the endophagous braconid Aphidius ervi (Hymenoptera, Braconidae) has a negative impact on the reproductive activity of its host, Acyrthosiphon pisum (Homoptera, Aphididae). The host castration is induced by the parasitoid venom and is reproduced by the injection of chromatographic fractions highly enriched with two proteins, of 18 (p18) and 36 kDa (p36) in size, respectively. Here we demonstrate that these bioactive proteins trigger apoptosis of the cells in the germaria and ovariole sheath of the host aphid. Both p18 and p36 were internally sequenced and the gathered information was matched against the deduced amino acid sequence of the putative proteins encoded by cDNA clones, randomly selected from a cDNA library, which was raised using mRNA extracted from A. ervi venom glands. The identified cDNA clones contained an insert corresponding to the RNA product of an interrupted gene, made of six exons and five introns, which was found to be transcribed at higher levels in adult females of A. ervi than in males. This gene codes for a putative protein composed of 541 amino acids, with a calculated molecular mass of 56.9 kDa, which contained the amino acid sequences experimentally determined for both p18 and p36. This putative protein showed a significant level of sequence identity with gamma-glutamyl transpeptidases (gamma-GT), and it was named Ae-gamma-GT. The gamma-GTs are enzymes which play a key role in the metabolism of glutathione (GSH) and, as observed in most organisms, they are membrane-bound heterodimers formed by a large and a small subunit, which originate by post-translational processing of a single-chain precursor. The expression in insect cells of Ae-gamma-GT confirmed the occurrence of the expected post-translational processing, and demonstrated that, unlike other gamma-GTs, this protein is secreted in the extracellular environment. A measurable gamma-GT activity was detected in the venom of A. ervi and in the chromatographic fractions containing Ae-gamma-GT. Thus, we suggest that this venom protein may induce apoptosis in the host ovarioles by generating an alteration of the GSH metabolism and a consequent oxidative stress.

The genomic sequence of the bracovirus associated with the wasp Toxoneuron nigriceps (Hymenoptera, Braconidae) (TnBV), an endophagous parasitoid of the tobacco budworm larvae, Heliothis virescens (Lepidoptera, Noctuidae), contains a large gene family coding for protein tyrosine phosphatases (PTPs). Here we report the characterization of cDNAs for two of the viral PTPs isolated by screening a cDNA library from haemocytes of parasitized host larvae. The two encoded proteins show 70% amino acid identity and are expressed in the fat body of parasitized hosts. In addition, one was expressed in inactivated prothoracic glands (PTGs), 24 h after parasitoid oviposition. The rapid block of ecdysteroidogenesis does not appear to be due to inhibition of general protein synthesis, as indirectly indicated by the unaltered S6 kinase activity in the cytosolic extracts of basal PTGs from parasitized host larvae. Rather, TnBV PTP over-expression in inactivated host PTGs suggests that gland function may be affected by the disruption of the phosphorylation balance of key proteins regulating points upstream from the ribosomal S6 phosphorylation in the PTTH signaling cascade.
