Floral Specialization and Bat Pollination in Subtribe Cereinae (Cactaceae): A Morphological Approach
Cactaceae has many vertebrate-pollinated species, and in the subtribe Cereinae, several genera are indicated as being pollinated by bats. In this subtribe, we observed phenotypic specialization in floral morphological attributes associated with ...

Floral biology of Avena strigosa
Black oat is a plant of multiple uses in the agricultural system, however breeding programs have little success in getting new genotypes, without knowing the exact reason, so this study had the goal to characterize the floral morphology and to evaluate if there is variability in Avena strigosa in its pollen viability.

Floral biology of cacauhy (Theobroma speciosum - Malvaceae)
In the present work, cacauhy's (Theobroma speciosum) floral biology was studied. Flower buds split their sepals at 14h reaching its maximum at 22h, but all flowers were fully opened at 6:00 h of the following morning.

Floral biology of candeia (Eremanthus erythropappus, Asteraceae)
Floral biology and pollinators of candeia (Eremanthus erythropappus) were analyzed in a natural population. We studied anthesis, flower morphology, stigmatic receptivity, pollen viability and floral visitors.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Floral resource availability of Dicliptera squarrosa (Acanthaceae) and its dependence on hummingbirds for fruit formation in a forest fragment of Central Brazil [PDF]
Background and aims – Hummingbirds are dependent and specialized on nectar-feeding, and many plants depend upon them for pollination. However, the degree of plant-pollinator interdependence varies greatly among species; thus, information on plant mating ...
