Phylogenetic aspects, hotspots of nucleotide divergence, highly divergent genes, and specific RNA editing sites have been identified and characterized in the plastomes of the subgenus Passiflora. The genus Passiflora comprises more than 500 species across five subgenera: Astrophea, Decaloba, Deidamioides, Passiflora, and Tetrapathea. The most economically relevant species belong to the subgenus Passiflora, whose genetic pool and diversity among wild species remain poorly characterized. Similarly, little is known about the interspecific relationships within the subgenus Passiflora and the genetic causes of nuclear-cytoplasmic incompatibility observed in interspecific hybrids. Here, we report the complete nucleotide sequences of six plastomes belonging to species of the subgenus Passiflora, with the aim of better understanding the evolution of the plastome in this subgenus. Complete plastome sequences revealed five hotspots of nucleotide polymorphism: three intergenic regions and two coding sequences. Moreover, among 70 RNA editing sites predicted in our analysis for the subgenus Passiflora, 38 were not shared by all analyzed species, highlighting their species-specific occurrence. Furthermore, phylogenies based on plastid sequences accurately resolved most relationships between species and suggested a non-monophyletic origin of three super-sections of the subgenus Passiflora, previously defined solely based on morphological traits. Finally, our findings identified putative candidates, including predicted RNA editing sites and the coding sequences of accD and clpP genes, responsible for nuclear-cytoplasmic incompatibility in the interspecific hybrids of Passiflora.

Primates are great fruit consumers and disperse intact seeds from most of the plants they consume, but effective seed dispersal depends, amongst other factors, on handling behavior. Likewise, the treatment in gut and mouth may alter seed fate. Overall, frugivore and folivore-frugivore primates are recognized to provide beneficial gut treatment for Neotropical plant species, but this effect might be overlooked at species-specific levels. In this study, we assessed the role of the southern muriqui (Brachyteles arachnoides), an endangered and endemic primate living in restricted fragments of the Brazilian Atlantic Forest, on potential quality of seed dispersal of native plants. Our main goals were to understand the effect of seed ingestion by this large-bodied atelid on germination of defecated seeds and in seed recovery by offering wild fruits of native species to captive individuals. We found that seven out of nine plant species were defecated intact and were able to germinate. Of those seven, one species showed enhanced and another showed decreased germination potential after defecation, while three species germinated faster after being defecated. The remaining species showed no differences from control seeds. The two non-germinating species were heavily predated, and average seed recovery was lower than expected, suggesting high levels of seed predation. The largest species offered (Inga vulpina) showed the highest dispersal potential. Our data support an overall neutral or potentially positive role of southern muriquis in seed dispersal quality for seven out of nine Atlantic Forest plant species, highlighting these primates’ potential to produce an effective seed rain.

Histoplasma capsulatum complex
resumo ...
Central nervous system (CNS) infection by Histoplasma capsulatum is a rare disease in immunocompromised individuals in endemic areas. About one quarter of cases result from hematogenous dissemination. A 23-year-old upholsterer with chronic occipital headache had developed intracranial hypertension and dizziness, incoordination with ataxic gait, and acute confusion 5 months prior to admission. Laboratory examinations and chest roentgenogram were normal. Postcontrast T1-weighted MRI of the brain revealed a multiple ring-enhancing cerebellar, brain stem and parietal lobe lesions, and meningeal contrast enhancement. Cerebrospinal fluid culture was positive for H. capsulatum species complex, which was confirmed by phylogenetic analysis. Thirteen years after the diagnosis and treatment, there was no H. capsulatum recurrence; sequels related to complications due to the ventriculoperitoneal shunt. This case shows a primary neurological presentation of cerebral histoplasmosis, without meningitis or disseminated disease in nonimmune-compromised patient. The authors propose a categorization of the diagnosis of CNS histoplasmosis. Routine diagnostics of sibling species within the H. capsulatum complex proved to be difficult.
