Plant Physiol Biochem

January 2025

Laboratory of Microbial Genetics, Department of Botany, Institute of Science, Banaras Hindu University, Varanasi, 221005, India. Electronic address:

Nitric oxide synthases (NOSs) are heme-based monooxygenases that catalyze the NADPH-dependent oxidation of L-arginine to produce NO and L-citrulline. Over the past five years, the identification and characterization of NOS homologs in cyanobacteria have significantly advanced our understanding of these enzymes. However, the precise mechanisms through which NOS-derived NO influences nitrogen metabolism remain incompletely elucidated.

The Indian subcontinent has emerged as a natural habitat to several cyanobacterial taxa which have been explored and described in the past few years using a polyphasic approach. Various new genera and species of Nostoc morphotypes, heteropolar unbranched as well as branched heterocytous cyanobacteria, have been described from various parts of India such as the central mainland, temperate hill stations of extreme northern India, and the biodiversity hotspots of northeast India. Konkan, a small strip of land bounded by Arabian sea on the west and Sahyadri mountains on the east, has various habitats such as coastal beds, old monuments, freshwater lakes, and rivers; however, this region has been less charted in modern cyanobacterial systematics, relative to others.

Hypoxia is a significant stressor, and stabilized hypoxia-inducible factor-1α (HIF-1α) regulates the expression of numerous genes, leading to various biochemical, molecular, physiological and genomic changes. The body's oxygen-sensing system activates gene expression to protect brain tissues from hypoxia. Gamma-aminobutyric acid, an inhibitory neurotransmitter, regulates brain excitability during hypoxia through the activation of HIF-1 α.

Recurrent pregnancy loss (RPL), defined as two or more consecutive miscarriages before 20 weeks of gestation, affects 1-2% of couples worldwide. Pro-inflammatory cytokines, such as TNF-α, IL-1β and IL-6 play critical roles in early pregnancy, while anti-inflammatory cytokines like TGF-β and IL-10 promote immune tolerance to prevent harmful inflammatory responses that play important role in placental and fetal development. This aim of the study is to analyse the levels of inflammatory cytokines in blood serum from RPL patients and healthy women (control).
