Article Abstract
The genetic consequences of adaptation to changing environments can be deciphered using population genomics, which may help predict species' responses to global climate change. Towards this, we used genome-wide SNP marker analysis to determine population structure and patterns of genetic differentiation in terms of neutral and adaptive genetic variation in the natural range of Eucalyptus grandis, a widely cultivated subtropical and temperate species, serving as genomic reference for the genus. We analysed introgression patterns at subchromosomal resolution using a modified ancestry mapping approach and identified provenances with extensive interspecific introgression in response to increased aridity. Furthermore, we describe potentially adaptive genetic variation as explained by environment-associated SNP markers, which also led to the discovery of what is likely a large structural variant. Finally, we show that genes linked to these markers are enriched for biotic and abiotic stress responses.

The gene family participates in crucial processes including plant development, stress adaptation, and hormonal signaling cascades. While the gene family has been extensively characterized in model plant systems and agricultural crops, its functional role in , a commercially valuable tree species of significant ecological and economic importance, remains largely unexplored. In the present investigation, systematic identification and characterization of the gene family were performed in using a combination of genome-wide bioinformatics approaches and RNA-seq-based expression profiling.

Malate dehydrogenases are pivotal in plant metabolism and stress responses, yet their evolutionary dynamics and functional diversification in woody angiosperms remain underexplored. This study comprehensively characterized the MDH (EgMDH) gene family to elucidate its roles in development and environmental adaptation. We identified 14 genes and conducted phylogenetic, structural, and syntenic analyses to trace their evolutionary origins.

Plant roots live in constant contact with diverse microbes in the soil. Plant fitness, therefore, relies on signaling pathways that mount an effective immune response against pathogens while fostering mutualistic symbioses. Plant pathways, and specifically immune genes that may act as "switches," discriminating between pathogenic or mutualistic fungi, remain largely unknown.

Background: is one of the most important fast-growing tree species in the world, and its growth and development are significantly affected by nitrogen and phosphorus. The Amino acid/auxin permease (AAAP) gene family plays key roles in long-distance amino acid transport in plants, but their evolutionary diversity and gene expression analysis in under nutrient deficiency stress are largely unexplored.
Results: This study presents the first genome-wide identification and functional characterization of 78 AAAP family genes (EgAAAPs) in , classified into eight subfamilies.
