Defining a highly conserved B cell epitope in the receptor binding motif of SARS-CoV-2 spike glycoprotein.

SARS-CoV-2 mRNA vaccines induce robust and persistent germinal centre (GC) B cell responses in humans. It remains unclear how the continuous evolution of the virus impacts the breadth of the induced GC B cell response. Using ultrasound-guided fine needle aspiration, we examined draining lymph nodes of nine healthy adults following bivalent booster immunization.

Isolation and characterization of plant growth promoting rhizobacteria from cacti root under drought condition.

Plant growth-promoting rhizobia (PGPR) helps plants grow and develop by protecting them from abiotic and biotic stresses, increasing the synthesis of chemicals that promote growth, and enabling the uptake of nutrients. Drought is one of the biggest problems throughout the world. The search for novel and efficient drought-resistant microorganisms that reduce the adverse effects executed by drought is a significant alternative.

New records of the primarily Sri Lankan Pseudophilautus regius (Manamendra-Arachchi & Pethiyagoda, 2005) (Amphibia; Rhacophoridae) from the Eastern Ghats of India, crossing the Palk Strait saltwater barrier in the Indian Ocean.

Pseudophilautus regius is a bush frog originally described from the dry zones of Sri Lanka. In the present study, P. regius is being reported from the Eastern Ghats of Andhra Pradesh, India as a new record for the country.

A Catalogue of Indian Hydrophiloidea (Insecta: Coleoptera).

This catalogue lists 286 valid species included in 49 genera and six families of the superfamily Hydrophiloidea (Coleoptera), recorded from India. The family Helophoridae accommodates eight species (one genus), Epimetopidae five species (one genus), Georissidae seven species (one genus), Hydrochidae four species (one genus), Spercheidae two species (one genus), and Hydrophilidae 260 species (44 genera). Of these, 113 species are apparently endemic to India.
