Although DNA analysis revealed that her infant was not a product of inbreeding, the pair copulated frequently in the latter half of her estrus period, suggesting that they did not avoid incest behaviorally to avoid inbreeding. Furthermore, there was no hard evidence that the remaining female avoided mating with her maternal brother, suggesting that incest avoidance may not be a proximate factor responsible for female dispersal.The current pandemic represents unprecedented times in medical education. In addition to the already strenuous demands of medical school, the SARS-CoVid-2 pandemic introduced a new source of ethical and moral pressure on students. Medical students navigated finishing their didactic years in isolation and initiated their clinical rotations in a pandemic environment. Many medical students found themselves in the frustrating position of being non-essential healthcare workers but still wanting to help. This paper follows the personal and shared experiences of a second-year medical student transitioning to their third year. In particular, this paper examines the author's personal ties to the disability community through their family, and how this impacted their approach in striving to aid in the pandemic.Genus Zephyranthes consists of economically important plant species due to their high ornamental value and presence of valuable bioactive compounds. However, this genus propagates by asexual division only which gives slow propagation rate. Plant tissue culture has the potential to provide efficient techniques for rapid multiplication and genetic improvement of the genus. In this work, a dual in vitro regeneration system through callus mediated shoot regeneration and direct shoot regeneration in species Zephyranthes candida, Zephyranthes grandiflora and Zephyranthes citrina was investigated. Bulb, leaf and root explants were cultured on Murashige and Skoog (MS) medium amended with different plant growth regulators (PGR's) viz. 2,4-dichlorophenoxyacetic acid (2,4-D), 1-Naphthalene acetic acid (NAA), 6-benzyl amino purine (BAP), N-phenyl-N'-1,2,3 -thiadiazol-5-ylurea (TDZ), 6-Furfuryl- aminopurine (KIN) alone or in combinations for callus induction and regeneration. Only bulb explants showed callus induction andsee text] TDZ amended MS media. Adventitious root induction was achieved on 2 mg L[Formula see text] IBA with a maximum of 8 roots per shoot. The in vitro raised plantlets were successfully acclimatized in the field with 85% survival efficiency. The genome size (2C DNA content) of the field-grown plants and in vitro regenerated plants, evaluated through flow cytometry technique, were similar and showed no ploidy changes. An efficient mass propagation protocol was established for obtaining plants with unaltered genome size in the three species of Zephyranthes.Wild Solanum species are the important resources for potato improvement. With the availability of potato genome and sequencing progress, knowledge about genomic resources is essential for novel genes discovery. Hence, the aim of this study was to decipher draft genome sequences of unique potato genotypes i.e. somatic hybrid P8 (J1), wild species S. pinnatisectum (J2), progeny MSH/14-112 (P8 × cv. Kufri Jyoti) (J3), and S. tuberosum dihaploid C-13 (J4). Draft genome sequencing using Illumina platform and reference-based assemblies with the potato genome yielded genome assembly size of 725.01 Mb (J1), 724.95 Mb (J2), 725.01 Mb (J3), and 809.59 Mb (J4). Further, 39,260 (J1), 25,711 (J2), 39,730 (J3) and 30,241 (J4) genes were identified and 17,411 genes were found common in the genotypes particularly late blight resistance genes (R3a, RGA2, RGA3, R1B-16, Rpi-blb2, Rpi and Rpi-vnt1). selleck chemicals Gene ontology (GO) analysis showed that molecular function was predominant and signal transduction was major KEGG pathways. Further, gene enrichment analysis revealed dominance of metabolic process (GO 0008152) in all the samples. Phylogeny analysis showed relatedness with potato and other plant species. Heterozygous single nucleotide polymorphism (SNP) was more than homozygous, and SNP in genic region was more than inter-genic region. Copy number variation (CNV) analysis indicated greater number of deletions than duplications. Sequence diversity and conserved motifs analysis revealed variation for late blight resistance genes. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis showed differential expression of late blight resistance genes. Our study provides insights on genome sequence, structural variation and late blight resistance genes in potato somatic hybrid (parents and progeny) for future research.The vertebrate mitochondrial genome is typically circular molecules made up of 14,000 to 16,000 bp, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (12 s rRNA and 16 s rRNA) and a control region. Compared with nuclear DNA, mitochondrial DNA has a higher mutation rate, so it is one of the most effective and reliable molecular markers in fish phylogeny. Macrotocinclus affinis was the only species in Macrotocinclus (it was classified as Otocinclus in the past) and currently lacks genetic information. Most of the current researches are based on the mitochondrial Cytb gene and RAG1 and RAG2 nuclear genes to study the phylogenetic analysis of Siluriformes. So, the study provides the characteristic features of the Macrotocinclus affinis mitochondrial genome and this is the first time that the phylogenetic relationship of Siluriformes has been reconstructed based on COI. We aimed to sequence the entire mitochondrial genome of Macrotocinclus affinis using conventional PCR techniques and to clarify its phylogenetic status in Siluriformes by using the COI sequence of mitochondria. In this study, we sequenced the whole mitochondrial genome of this species yielding a 16,632 bp circular assembly composed of the typical vertebrate mitochondrial features. It contains 13 protein-coding genes, two rRNA genes, 22 tRNA genes, a putative control region, and one origin of replication on the light-strand. The overall base composition includes A (30.07%), T (24.43%), C (29.43%) and G (16.01%). The genome composition is A + T biased (54.5%), and exhibits AT-skew (0.1036) and GC-skew (-0.2962). Moreover, the 13 PCGs encode 3850 amino acids in total. The result of the phylogenetic tree supports Macrotocinclus affinis has a closest relationship with Otocinclus cf. hoppei far. These results will help to understand the characteristics of the mitochondrial genome of Macrotocinclus affinis and provide molecular basis for the evolutionary relationship of Loricariidae.
