Genetic divergence, heritability and genetic advance in mutant lines of urdbean [Vigna mungo (L.) Hepper]

open access: yes, 2017
Twenty six mutant lines of urdbean [Vigna mungo (L) Hepper] were analyzed for genetic diversity using Mahalanobis D2 statistics. Based on twelve important agronomic characters, the genotypes were grouped into 4 clusters.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Linkage disequilibrium and genetic variability

open access: yesGenetical Research, 1974
SUMMARY It has been shown previously that, even in the absence of linkage, selection can cause an appreciable change in the genetic variance of a metric character due to disequilibrium; this change is temporary and is rapidly reversed when selection ceases.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Detection of genetic diversity among Indian strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ using PCR-RAPD [PDF]

open access: yes, 2008
The randomly amplified polymorphic DNA (RAPD) technique was used to investigate the genetic diversity in 6 strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ (_Xcmi_), the causal pathogen of mango bacterial canker disease (MBCD).

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
