Abstract Assortative mating and sexual selection are widespread in nature can play an important role speciation, through the buildup maintenance of reproductive isolation (RI). However, their contribution to genome-wide suppression gene flow during RI is rarely quantified. Here, we consider a polygenic ‘magic’ trait that divergently selected across two populations connected by migration, while also serving as basis assortative mating, thus generating on one or both sexes. We obtain theoretical predictions for divergence at individual loci assuming effect all other any locus be encapsulated via effective migration rate, which bears simple relationship measurable fitness components migrants various early generation hybrids. Our analysis clarifies how ‘tipping points’ (characterised abrupt collapse adaptive divergence) arise, when shift critical level beyond collapses. quantify relative contributions viability barriers discuss these depend existing levels. results suggest rates provide useful way understanding genomic divergence, even scenarios involving multiple, interacting mechanisms RI.

Abstract Speciation is responsible for the diversity of species observed today and corresponds to build-up reproductive isolation between populations. Reproductive can be generated by different mechanisms that have been extensively characterized, yet how their interactions affect speciation remains largely unknown. Here, we explicitly model interaction three key (local adaptation, mate choice genetic hybrid incompatibilities) quantifying relative contribution evolution isolation. We modeled two populations exchanging migrants using Fisher Geometric Model local phenotype matching choice, multiple pairs Bateson-Dobzhansky-Muller Incompatibilities (DMI). All were determined same set loci, creating conditions barriers both at population levels. found no cases where evolved. Instead, could evolve depending on migration rate: either adaptation incompatibilities limited migration, or higher migration. Our results showed due ecological differentiation was first far most effective barrier. Finally, demonstrated in a polygenic model, become locally adapted strict they would not accumulate provided there sufficient gene flow.

Abstract Background Plant growth promotion through microbial mediation has garnered increasing focus in sustainable agriculture because of its capacity to enhance agricultural yield mustard [Brassica juncea (L.) Czern] as well resilience. Bacillus pumilus, a PGPR, is known for synthesizing key phytohormones, such IAA, which play crucial role modulating plant development. Tryptophan, precursor IAA biosynthesis, another essential compound linked the plant-bacteria interaction. HPLC serves powerful tool precise quantification these metabolites, offering insights into mechanisms promoting growth. Additionally, antagonism against pathogens, Fusarium equiseti, further highlights potential pumilus crop protection. Results In this study, bacterial isolate identified was evaluated PGP traits. The demonstrated production significant amounts confirmed analysis, revealing metabolic enhancing Alongside production, exhibited other in vitro activities, phosphate solubilization, and siderophore are critical improving nutrient availability plants. Furthermore, showed strong antagonistic activity notorious soil-borne pathogen, suggesting biocontrol. Conclusion study underscores potent IAA-producing PGPR with multiple growth-promoting traits effective equiseti. use accurate tryptophan provides valuable driving promotion. These findings emphasize bioinoculant agriculture, dual benefit productivity providing natural protection pathogens. This research microbial-mediated strategies advancing environmentally farming practices.
