Abstract:
... High-throughput (HTP) plant phenotyping approaches are developing rapidly and are already helping to bridge the genotype–phenotype gap. However, technologies should be developed beyond current physico-spectral evaluations to extend our analytical capacities to the subcellular level. Metabolites define and determine many key physiological and agronomic features in plants and an ability to integrate ...

Abstract:
... Drought management largely depends on the availability of timely, accurate and integrated information about its characteristics. Concurrently, biostimulants could represent a sustainable measure to foster the resilience of cropping systems under water-limited conditions. Nevertheless, scientific recognition of the potential of biostimulants has not grown as fast as the interest from industry: ther ...
... Detecting and characterizing spikes from wheat field images is essential in wheat growth monitoring for precision farming. Along with various technological developments, deep-learning-based methods have remarkably improved wheat spike detection performance. However, detecting small and overlapping wheat spikes in UAV images is still challenging because high spike occlusion and complex background c ...
... Despite widespread evidence of urban evolution, the adaptive nature of these changes is often unclear. We review different phenotypic and molecular lines of evidence used for assessing urban adaptation, discussing the benefits and limitations of each approach, and rare examples of their integration. We then provide a synthesis of local adaptation to urban and rural environments. These data were dr ...
... Strongyloides’ developmental switch between direct, parasitic and indirect, free-living development has intrigued, confused, and fascinated biologists since it was first discovered more than 100 years ago. Proximately, the switch is controlled by environmental conditions that developing larvae are exposed to, but genotypes differ in their sensitivity to these cues. Ultimately, selection will act o ...
... Inevitable environmental changes empower the researchers to understand and analyze the plant traits for improving the ecosystem. Solar-induced fluorescence (SIF) is one of the functional traits to analyze the vegetation and assess plant phenotyping. Estimation of SIF through hyperspectral imaging technique gaining its popularity in the recent days than any other estimating techniques due to its co ...
... BACKGROUND: Segmentation of structural parts of 3D models of plants is an important step for plant phenotyping, especially for monitoring architectural and morphological traits. Current state-of-the art approaches rely on hand-crafted 3D local features for modeling geometric variations in plant structures. While recent advancements in deep learning on point clouds have the potential of extracting ...
... 1. Communication among family members is often essential for navigating the social and trophic interactions that arise during parental care. In insects, this communication is often accomplished via pheromonal signals. However, some insects also produce acoustic signals (stridulations) during parental care. 2. Burying beetles (Nicrophorus spp) audibly stridulate during mating and parental care and ...
... Background: Poirier–Bienvenu Neurodevelopmental Syndrome (POBINDS) is a rare disease linked to mutations of the CSNK2B gene, which encodes for a subunit of caseinkinase CK2 involved in neuronal growth and synaptic transmission. Its main features include early-onset epilepsy and intellectual disability. Despite the lack of cases described, it appears that POBINDS could manifest with a wide range of ...

Abstract:
... The field of paleolimnology has made tremendous progress in reconstructing past biotic and abiotic environmental conditions of aquatic ecosystems based on sediment records. This, together with the rapid development of molecular technologies, provides new opportunities for studying evolutionary processes affecting lacustrine communities over multicentennial to millennial timescales. From an evoluti ...

Abstract:
... CRISPR-based systems have fundamentally transformed our ability to study and manipulate stem cells. We explored the possibility of using catalytically dead Cas9 (dCas9) from S. pyogenes as a platform for targeted epigenetic editing in stem cells to enhance the expression of the eomesodermin gene (EOMES) during differentiation. We observed, however, that the dCas9 protein itself exerts a potential ...

Abstract:
... KEY MESSAGE: We propose a novel approach to the Bayesian optimization of multivariate genomic prediction models based on secondary traits to improve accuracy gains and phenotyping costs via efficient Pareto frontier estimation. Multivariate genomic prediction based on secondary traits, such as data from various omics technologies including high-throughput phenotyping (e.g., unmanned aerial vehicle ...

Abstract:
... The Corfu δ⁰β⁺ thalassemic allele is a unique thalassemic allele consisting of the simultaneous presence in cis of a deletion of the δ-globin (Hemoglobin Subunit Delta, HBD) and a single nucleotide variant in the β-globin gene (Hemoglobin Subunit Beta, HBB). The allele has, so far, been described in individuals of Greek origin. The objectives of the study are to ascertain the prevalence of the Cor ...

Abstract:
... Metabolic interactions between auxotrophs and prototrophs in microbial communities are understudied. Yu, Correia-Melo and colleagues showed how intra-cellular as well as inter-cellular metabolism affects community fitness in the absence and presence of abiotic stress, i.e., drugs. ...

Abstract:
... As a homologous organ of the leaf, the pod is an essential factor in determining the yield and quality of the grain. The physiological and ecological characteristics of pods are a critical basis for soybean breeding and yield estimation. In order to avoid time-consuming and laborious problems in the traditional manual measurement process, a fast calculation method of pod's phenotypic traits was pr ...

Abstract:
... Several genetic variants have been shown to affect the mean number of offspring in different sheep breeds. Here, we analyzed samples from Icelandic sheep with the aim of identifying the genetic cause of the Icelandic Loa phenotype using three previously identified prolificacy genes as candidates. We demonstrate that a 4‐bp frameshift deletion positioned in the mature region of the GDF9 protein in ...

Abstract:
... In traditional theories, bet‐hedging in evolutionary biology is defined as a trade‐off between the within‐generation arithmetic mean fitness (AMF) of a genotype and between‐generation variance (BGV) in AMF across generations. The rationale of this definition is that a bet‐hedger genotype suppresses the BGV to increase between‐generation geometric mean fitness (GMF; an index of long‐term sustainabi ...

Abstract:
... Metal homeostasis is fundamental for optimal performance of cell metabolic pathways. Over the course of evolution, several systems emerged to warrant an intracellular metal equilibrium. When exposed to growth-challenging copper concentrations, Gram-negative bacteria quickly activate copper-detoxification mechanisms, dependent on transmembrane-protein complexes and metallochaperones that mediate me ...

Abstract:
... The biotic and abiotic factors of an ecosystem exert an influence on the behavior and survival of organisms, which adapt to changes in these factors to ensure their reproduction and survival. Phenotypic plasticity regards any type of change induced by the environment without the need for genetic modifications. The aim of the present study was to evaluate whether the investment of the antlion, Myrm ...

Abstract:
... For much of the twentieth century, it was accepted that genes dictate phenotypes. Nevertheless, genetics in combination with molecular biology and genomics has facilitated the explanation of some peculiar molecular phenomena. Most eukaryotic genomes are crammed with noncoding DNA, which was previously hypothesized to be selfish DNA, with only a small fraction of sequences encoding proteins. We now ...
