Microbes in floral nectar can impact both their host plants and visitors, yet little is known about the microbiome of most pollinator-dependent crops. In this study, we examined abundance composition fungi bacteria inhabiting Vaccinium spp. nectar, as well volume sugar concentrations. We compared wild V. myrsinites with two field-grown corymbosum cultivars collected from organic conventional farms. Differences traits microbiomes were identified between but not species. The cultivated also...
Floral nectar often contains pollen and microorganisms, which may change nectar's chemical composition, in turn impact pollinator affinity. However, their individual combined effects remain understudied. Here, we examined the impacts of specialist yeast, Metschnikowia reukaufii, addition sunflower (Hellianthus annus) pollen. Pollen grains remained intact, yet still increased yeast growth amino acid concentrations nectar, whereas depleted acids. Pollen, but not changed sugar by converting...
Divergent natural selection has the potential to drive evolution of reproductive isolation. The euryhaline killifish Lucania parva stable populations in both fresh water and salt water. its sister species, freshwater L. goodei , are isolated by prezygotic postzygotic barriers. To further test whether adaptation salinity led these isolating barriers, we tested for incipient isolation within crossing saltwater populations. We found no evidence isolation, but reduced hybrid survival indicated...
Understanding yeast dynamics during fermentation is important for quality control, whether monitoring consistency or identifying aberrant events, such as premature flocculation (PYF). Previous models of tend to be parameter rich and require large time series, which are rare in industry. This research investigates five simpler 1) describe dynamics, 2) refine control sampling regimes improve model fit, 3) identify PYF fermentations. The ability these was evaluated using fitting with series...
Recently, there has been an increase in the number of reports that highlight role microbes and their volatile metabolites interactions with plants insects, including which may benefit agricultural production. Accurate reproducible collection is crucial to investigations chemical-mediated communication between organisms. Accordingly, accurate detection volatiles emitted from microbe-inoculated media a research priority. Though numerous classes organic compounds are plants, microbes, emissions...
Flocculation of yeast is a natural phenomenon wherein cells clump together and come out suspension. This often relied upon by brewers as means removing yeast, clumps (flocs) typically precipitate from the fermentation vessel. A problem that has long frustrated when flocculation does not proceed expected. been linked to fermentation's premature ending ("hung" fermentation). Since early 1900s, researchers have explored numerous methods identify characteristics yeast. Traditional contributed an...
Abstract Microbes in floral nectar can impact both their host plants and visitors, yet little is known about the microbiome of most pollinator-dependent crops. In this study, we examined abundance composition fungi bacteria inhabiting Vaccinium spp. nectar, as well volume sugar concentrations, hypothesizing that traits microbial communities would vary between plants. We compared wild V. myrsinites with two field-grown corymbosum cultivars collected from organic conventional farms....
