Beyond COP28: Brazil must act to tackle the global climate and biodiversity crisis.

Extreme weather has made 2023 virtually certain to be the warmest year on record, signaling unprecedented climate and biodiversity crises. Brazil, the world’s most biodiverse country, with two hotspots and complex social and economic layers, has experienced escalating environmental degradation over the past years. Alarming rates of native vegetation loss, wildfires, severe and prolonged droughts, and heatwaves have adversely impacted several Brazilian ecosystems and societies.

Detection and molecular characterization of a novel mitovirus associated with Passiflora edulis Sims.

Mitoviruses are cryptic capsidless viruses belonging to the family Mitoviridae that replicate and are maintained in the mitochondria of fungi. Complete mitovirus-like sequences were recently assembled from plant transcriptome data and plant leaf tissue samples. Passion fruit (Passiflora spp.

Advances in Tissue Culture and Transformation Studies in Non-model Species: Passiflora spp. (Passifloraceae).

In this chapter, we report advances in tissue culture applied to Passiflora. We present reproducible protocols for somatic embryogenesis, endosperm-derived triploid production, and genetic transformation for such species knowledge generated by our research team and collaborators in the last 20 years. Our research group has pioneered the work on passion fruit somatic embryogenesis, and we directed efforts to characterize several aspects of this morphogenic pathway.

Distinct Bleaching Resilience of Photosynthetic Plastid-Bearing Mollusks Under Thermal Stress and High CO Conditions.

The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling symbiotic features observed in the animal kingdom, i.e.
