ds that contained endosperm with the regular number of chromosomes and hence escaped the triploid block.These new results show that polyspermy provides plants with a means to essentially sneak extra copies of DNA ‘behind the back’ of the DNA-sensitive endosperm and into the next generation. They also give new insight in how polyploidization may have shaped the evolution of flowering plants and have important implications for agriculture where the breeding of new “hybrid” crops has often been limited by incompatibilities in the endosperm. © 2020, Mao et al.Fertilization of an egg cell by more than one sperm cell can produce viable progeny in a flowering plant. © 2020, Chaudhary et al.A Gram-stain-negative bacterium, designated strain PF-30T, was isolated from floodwater of a paddy field in South Korea. Strain PF-30T was found to be a strictly aerobic, motile and pink-pigmented rods which can grow at 25-40 °C (optimum, 28 °C), at pH 5.0-9.0 (optimum pH 7.0) and at salinities of 0.5-3.0 % NaCl (optimum 0.5 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain PF-30T belongs to the genus Elioraea, showing highest sequence similarity to Elioraea tepidiphila TU-7T (97.1%) and less than 91.3 % similarity with other members of the family Acetobacteraceae. The average nucleotide identity (ANI) and DNA-DNA relatedness between the strain PF-30T and E. tepidiphila TU-7T yielded an ANI value of 75.1 % and DNA-DNA relatedness of 11.7±0.7 %, respectively. The major fatty acids were identified as C18  0 and C18  1 ω7c. The predominant respiratory quinone was identified as Q-10. The DNA G+C content was determined to be 69.9 mol%. The strain PF-30T was observed to produce plant-growth-promoting materials such as indole-3-acetic acid (IAA), siderophore and phytase. On the basis of the results from phylogenetic, chemotaxonomic and phenotypic data, we concluded that strain PF-30T represents a novel species of the genus Elioraea, for which the name Elioraea rosea sp. nov. is proposed. The type strain is PF-30T (=KACC 19985T=NBRC 113984T).RP11T was isolated from forest soil following enrichment with 4-hydroxybenzoic acid. Cells of RP11T are aerobic, non-sporulating, exhibit swimming motility, and are rods (0.8 µm by 1.4 µm) that often occur as diplobacillus or in short chains (3-4 cells). Optimal growth on minimal media containing 4-hydroxybenzoic acid (µ=0.216 hr-1) occurred at 30 °C, pH 6.5 or 7.0 and 0% salinity. Comparative chemotaxonomic, genomic and phylogenetic analyses revealed the isolate was distinct from its closest relative type strains identified as Paraburkholderia aspalathi LMG 27731T, Paraburkholderia fungorum LMG 16225T and Paraburkholderia caffeinilytica CF1T. Strain RP11T is genetically distinct from P. aspalathi, its closest relative, in terms of 16S rRNA gene sequence similarity (98.7%), genomic average nucleotide identity (94%) and in silico DNA-DNA hybridization (56.7 %±2.8). The composition of fatty acids and substrate utilization pattern differentiated strain RP11T from its closest relatives, including growth on phthalic acid. Strain RP11T encoded the greatest number of aromatic degradation genes of all eleven closely related type strains and uniquely encoded a phthalic acid dioxygenase and paralog of the 3-hydroxybenzoate 4-monooxygenase. The only ubiquinone detected in strain RP11T was Q-8, and the major cellular fatty acids were C16  0, 3OH-C16  0, C17  0 cyclo, C19  0 cyclo ω8c, and summed feature 8 (C18  1 ω7c/ω6c). On the basis of this polyphasic approach, it was determined that strain RP11T represents a novel species from the genus Paraburkholderia for which the name Paraburkholderia madseniana sp. nov. is proposed. The type strain is RP11T (=DSM 110123T=LMG 31517T).Dying, death, and grief are significant events that impact individuals, families, and communities. In the United States, Blacks historically have higher morbidity and mortality rates than other racial-ethnic groups. While death is a normal and natural phase of the life-course process, high incidents of infant mortality, premature death, and preventable death are not. The disproportionate burden of dying, death and grief among Blacks have detrimental consequences which demand interdisciplinary interventions from public health and death study researchers. This manuscript explores dying, death and grief from three distinct fields of study (1) epidemiology of death, (2) social epidemiology of death, and (3) thanatology.Objective Most sexual assault prevention approaches are universal in nature. The present study evaluated a Transtheoretical Model (TTM)-based Stages of Change (SOC) measure assessing readiness to utilize sexual assault risk reduction skills. The measure was evaluated with regard to Decisional Balance and Self-Efficacy. Participants Survey data were collected from 300 college women (Mage=18.5, SD = 0.79). Methods Three SOC measures were developed and evaluated for using 1) assertive responding; 2) self-protective dating behaviors; and 3) open sexual communication. Item development was followed by exploratory, confirmatory, and external validation analyses.  https://www.selleckchem.com/products/Temsirolimus.html  Results Exploratory Factor Analysis (EFA) indicated two, six-item factors (Positive Outcomes α=.91; Negative Outcomes α=.85) for Decisional Balance. Confirmatory Factor Analyses (CFA) supported a two-factor correlated model, χ2(66)=2101.70, p less then .001, CFI=.946, RMSEA=.083. For Self-Efficacy, EFA indicated one, six-item factor (α=.81). Conclusions These readiness assessments may guide understanding of factors influencing sexual assault risk reduction program outcomes and aid in tailoring program content.Due to their genomic variants, some individuals are more highly affected by toxicants than others. Toxicant metabolizing and activating variants have been linked with a wide variety of health issues including an increased risk of miscarriages, birth defects, Alzheimer's, benzene toxicity, mercury toxicity and cancer. The study of genomics allows a clinician to identify pathways that are less effective and then gives the clinician the opportunity to counsel their patients about diet, supplements and lifestyle modifications that can improve the function of these pathways or compensate to some extent for their deficits. This article will review a few of these critical pathways relating to phase I and phase 2 detox such as GSTP1, GPX1, GSTT1 deletions, PON1 and some of the CYP 450 system as examples of how an individual's genomic vulnerabilities to toxicants can be addressed by upregulating or downregulating specific pathways via genomically targeted use of foods, supplements and lifestyle changes.
