We evaluated adaptation to torpor and hibernation in the genus Dromiciops by comparing it with both torpid and non‐torpid marsupials, and investigated divergent selection signals between its two species. For the ancestral node, we identified positive selection in the genes PFKFB2, LAMP3, OTX1, and RAPSN, alongside an enrichment of pathways potentially ...

ABSTRACT Chronic antibiotic‐resistant cystic fibrosis (CF) lung infections are the leading cause of death in adults with CF. Despite advances in highly effective modulator therapies, microbial communities persist in the CF lung. The pathogenesis of CF airway infections can be exacerbated by pathogens such as Pseudomonas aeruginosa, which communicates ...

Age‐related downregulation of AcSirt2 impairs mitochondrial homeostasis in old bees. AcSirt2‐mediated deacetylation of FOXO enhances transcriptional activity, upregulating antioxidant enzymes (SOD, CAT) and promoting PINK1/Parkin‐mediated mitophagy. This pathway facilitates autophagosome formation and clearance of damaged mitochondria, reducing ROS ...

Environmental influences on the maximum quantum yield of terrestrial primary production
Temperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0) a constant value for each plant functional type. However, experimental studies have shown that ϕ0 – when measured on light‐adapted leaves

Estimating leaf photosynthesis in maize using chlorophyll fluorometry [PDF]
Genetic improvement of commercial maize hybrids has resulted in higher crop growth rates, which may be attributable to increased rates of photosynthetic carbon assimilation, decreased respiratory carbon losses, or both.

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.
