Horizontal Gene Transfer (HGT) is a major evolutionary force with a significant role in microbial evolution. In the present study, we report an in silico evidence for HGT of Phenol 2–Monooxygenase Gene which is responsible for converting Phenol to Catechol and is the initial and rate–limiting step in phenol degradation. Five computational approaches were applied across 75 completely sequenced prokaryotic genomes for studying the prospects of horizontal gene transfer of Phenol 2–Monooxygenase Gene. The phylogenetic incongruencies between the species tree (based on 16S rRNA gene) and the gene tree (using Phenol 2–Monooxygenase Gene) supported by high bootstrap values, discrepancies in %GC content, %GC3 content, codon usage analysis based on Codon Adaptation Index (CAI) and effective Number of codons (Nc) led to the conclusion that Horizontal Gene Transfer events might have taken place during the evolution of this gene. Tree and Reticulogram Reconstruction (T–REX) was constructed that detected the HGT events with significant bootstrap values, further making HGT an evident event in the evolution of this gene.Keywords

Over the past few decades, increase in life expectancy has facilitated longevity of family members but decreasing fertility rates have reduced the number of members to support each other, thereby giving birth to more complex family structures. This change in inter-personal dynamics has instigated major scientific attention towards its possible implication on various facets of intergenerational relationships and family life. Although the Theory of Intergenerational Solidarity and Theory of Ambivalence, have been by far the most widely utilized theoretical contributions, borrowed from social sciences, for conceptualization of this interpersonal exchange, however, they do not essentially cover all the underlying dynamics and therefore it is argued that still a need exists for theoretical guidance and further consolidation of the discipline, specially from the psychological and developmental perspective. With this respect, in the present article, the usefulness of the concept of generativity, from Erikson's theory of life span development, is reviewed and its contributions, limitations and prospects for understanding intergenerational relationships have been explored.Keywords
