Summary
Sorbus aucuparia subsp. aucuparia, ROWAN or MOUNTAIN ASH, is described and illustrated. Details of its distribution, genetic variability, cultural history and use by humans and animals are ...provided.
Picobirnavirus (PBV) is a small two-segmented double-stranded RNA (dsRNA) virus that has been identified in diarrheic feces of a large range of animal hosts, including humans. For this reason, PBV ...has been recognized as an opportunistic agent of gastrointestinal disease. Even under these circumstances, there is a lack of studies regarding this pathogen. Not outstanding, in Brazil, the single description of the PBV occurrence in pigs was provided in the 1980s. Hence, this study aimed to verify the PBV occurrence in Brazilian swine farms and to perform molecular characterization of the identified strains. High genetic variability was found in the analyzed sequences. Further studies comprehending the infection of swine by PBV in Brazilian herds should be performed to provide more accurate information on its epidemiology and to discuss the role of the virus in gastrointestinal diseases.

•Lemon-scented basil is known for its pleasant lemon aroma and diverse medicinal uses.•Besides genetic × environmental interactions associations play important role in genes ...expression.•Appropriate harvesting stage is full blooming stage in 75 days for maximum quality essential oil.•The distribution of PCA also proved high genetic variability based on morphological parameters.•The highest value of Citral I/nerol + geranial was found at the full blooming stage (75 days).
The lemon-scented basil (Ocimum africanum Lour.) is known for its pleasant lemon aroma and diverse medicinal uses. A field experiment was conducted in the two consecutive years, 2017–2018 and 2018–2019, at CSIR-CIMAP RC Hyderabad, India, on the effect of different harvesting intervals on agro parameters and chemical constituents of aromatic-cum-medicinal crop lemon-scented basil (Ocimum africanum Lour.). The study aims to standardize the appropriate harvesting time for the maximum essential oil yield with high citral content across the years/environments and recommendations for the best harvesting time. It is cleared from this investigation that the harvesting stage, traits, environment, and harvesting interval (H) × Years (Y), harvesting interval (H) × traits (T), traits (T) × years (Y), and harvesting interval (H) × traits (T) × years (Y) interactions play a vital role in operating the gene expression for the essential oil yield, and others quality characters in the O. africanum variety CIM Jyoti. The most appropriate harvesting stage is recommended at a full blooming stage in 75 days for maximum essential oil production.
Parkinson's disease is a complex neurodegenerative disorder for which both rare and common genetic variants contribute to disease risk, onset, and progression. Mutations in more than 20 genes have ...been associated with the disease, most of which are highly penetrant and often cause early onset or atypical symptoms. Although our understanding of the genetic basis of Parkinson's disease has advanced considerably, much remains to be done. Further disease-related common genetic variability remains to be identified and the work in identifying rare risk alleles has only just begun. To date, genome-wide association studies have identified 90 independent risk-associated variants. However, most of them have been identified in patients of European ancestry and we know relatively little of the genetics of Parkinson's disease in other populations. We have a limited understanding of the biological functions of the risk alleles that have been identified, although Parkinson's disease risk variants appear to be in close proximity to known Parkinson's disease genes and lysosomal-related genes. In the past decade, multiple efforts have been made to investigate the genetic architecture of Parkinson's disease, and emerging technologies, such as machine learning, single-cell RNA sequencing, and high-throughput screens, will improve our understanding of genetic risk.
An experiment was conducted with a simple lattice design with two replications to estimate the genetic variability in 62 soybean genotypes and 2 standard check varieties. The variability parameters ...such as mean, range of variation, genotypic and phenotypic coefficient of variation, heritability in the broad sense, genetic advance, and genetic advance as percentage of mean were estimated for 11 different traits. The values of the phenotypic coefficient of variation (PCV) were greater than the genotypic coefficient of variation (GCV) for all the traits, revealing the influence of environmental factors. The value of heritability was determined to be high for the traits such as grain yield, harvest index, number of seeds per pod, number of primary branches per plant, number of pods per plant and hundred seed weight. Indicating that the larger portion of total variation would be under genetic control and selection based on phenotypic levels would be useful for the improvement of these traits in soybean. High estimates of heritability together with high genetic advance as percentage of mean were recorded for grain yield, harvest index, number of seeds per pod, number of primary branches per plant, number of pods per plant and hundred seed weight, which may be attributed to the presence of additive gene action and had high selective value. Thus, selection pressure could successfully be applied to these traits for soybean improvement programs.
