Background: Alzheimer's Disease (AD) incidence is almost double in female than male, suggesting sex-specific AD risk genes remain unknown.
Method: We designed a statistical physics approach that exploits freely available but massive evolutionary and phylogenetic coupling data on sequence variation and speciation. These couplings lead to quantifiable values for the selection pressure exerted on the genes within a population.
Novel Insights into Hg Oxidation in Rice Leaf: Catalase Functions and Transcriptome Responses.

Rice leaves can assimilate atmospheric mercury (Hg), which is accumulated by grains and causes health risks to rice consumers. However, the molecular mechanisms underlying Hg assimilation in rice leaves remain poorly understood. Here, we investigated catalase's (CAT) function in Hg oxidation within rice leaves, as well as the Hg speciation and transcriptomic profiles of rice leaves exposed to Hg.

Whether large-scale variation in lineage diversification rates can be predicted by species properties at the population level is a key unresolved question at the interface between micro- and macroevolution. All else being equal, species with biological attributes that confer metapopulation stability should persist more often at timescales relevant to speciation and so give rise to new (incipient) forms that share these biological traits. Here, we develop a framework for testing the relationship between metapopulation properties related to persistence and phylogenetic speciation rates.

In plants, cellular function is orchestrated by three distinct genomes located within the nucleus, mitochondrion, and plastid. These genomes are interdependent, requiring tightly coordinated maintenance and expression. Plastids host several multisubunit protein complexes encoded by both the plastid and nuclear genomes.

We evaluate the evidence of cryptic speciation in Larimus breviceps, a species widely distributed in the western South Atlantic, from the Greater Antilles to Santa Catarina in Brazil. Mitochondrial (COI, Cyt b, and Control Region) and nuclear (IGF1 and Tmo-4C4) sequences were obtained from populations in the western South Atlantic. The analysis revealed two genetically distinct, sympatric lineages with no gene flow, with L.
