Eggs of Rana ridibunda, Rana lessonae and their hybrid Rana esculenta were examined for their immunochemical properties. The reaction spectra obtained confirm the hybrid origin of Rana esculenta.

The study explores the structural and functional dynamics of rhizospheric bacterial diversity in the Pranmati basin, focusing on their ecological significance, diversity, and functional roles across dominant vegetation types; Rhododendron arboreum, Myrica esculenta, and Quercus leucotrichophora. The research provides critical insights into soil health and ecosystem functioning by analysing rhizospheric soil properties among the selected vegetations. The research findings reveal that Myrica esculenta exhibits the highest root colonization (95.

Gametogenesis produces gametes as a piece of genetic information transmitted to the offspring. While during sexual reproduction, progeny inherits a mix of genetic material from both parents, asexually reproducing organisms transfer a copy of maternal or paternal DNA to the progeny clonally. Parthenogenetic, gynogenetic and hybridogenetic animals have developed various mechanisms of gametogenesis, however, their inheritance is not fully understood.

Background: Esculentin-1, initially discovered in the skin secretions of pool frogs (Pelophylax lessonae), has demonstrated broad-spectrum antimicrobial activity; however, its immunomodulatory properties have received little attention.
Results: In the present study, esculentin-1 cDNA was identified by analysing the skin transcriptome of the dark-spotted frog (Pelophylax nigromaculatus). Esculentin-1 from this species (esculentin-1PN) encompasses a signal peptide, an acidic spacer peptide, and a mature peptide.

Reproduction of water frog hybrids Pelophylax esculentus (Pelophylax ridibundus x Pelophylax lessonae) is associated with hemiclonal reproduction and backcrossing. The hemiclonal mode of reproduction occurs within P. esculentus allodiploids.

Amphibian species have the largest genome size enriched with repetitive sequences and relatively similar karyotypes. Moreover, many amphibian species frequently hybridize causing nuclear and mitochondrial genome introgressions. In addition, hybridization in some amphibian species may lead to clonality and polyploidization.
