One peculiarity of floral nectar that remains relatively unexplored from an ecological perspective is its role as a natural habitat for micro-organisms. This study assesses the frequency occurrence and abundance yeast cells in insect-pollinated plants three contrasting plant communities on two continents. Possible correlations between interspecific differences incidence pollinator composition are also explored.The was conducted at widely separated areas, Iberian Peninsula (Spain) one Yucatán...
Floral nectar of some animal-pollinated plants usually harbours highly adapted yeast communities which can profoundly alter characteristics and, therefore, potentially have significant impacts on plant reproduction through their effects insect foraging behaviour. Bacteria also been occasionally observed in floral nectar, but prevalence, phylogenetic diversity and ecological role within plant-pollinator-yeast systems remains unclear. Here we present the first reported survey bacteria from a...
There is increasing evidence that nectarivorous yeasts are an important third player in plant–pollinator mutualisms, but their distribution and ecological effects remain poorly known. Here we provide a survey of the frequency abundance floral nectar from 40 taxonomically diverse South African plant species, test whether they affect properties, investigate associations between yeast incidence pollinator type. Microscopical observations samples revealed widespread as by high percentage plants...
The genus Cytinus is composed of rootless, stemless and leafless parasites whose flowers are only visible during the reproductive period when they arise from host tissues. Most taxa occur in Madagascar South Africa, where mammal pollination has been suggested for one species. There species Mediterranean region, its system unknown. Here, a long-term field observation study combined with experimental treatments order to assess biology hypocistis. Field studies were carried out six populations...
Interactions between plants and ants abound in nature have significant consequences for ecosystem functioning. Recently, it has been suggested that nectar-foraging transport microorganisms to flowers; more specifically, they yeasts, which can potentially consume sugars alter nectar composition. Therefore, could indirectly change sugar profile, an important floral feature involved the plant-pollinator mutualism. But this novel role never tested. We here investigate effects of nectarivorous...

Nectar‐dwelling yeasts are emerging as widely distributed organisms playing a potentially significant and barely unexplored ecological role in plant pollinator mutualisms. Previous efforts at understanding nectar–pollinator–yeast interactions have focused on bee‐pollinated plants, while the importance of nectarivorous ants vectors for yeast dispersal remains so far. Here we assess abundance composition nectar fungal microbiota ant‐pollinated Cytinus hypocistis , study whether transmission is...
Abstract Floral nectar harbours a diverse microbiome of yeasts and bacteria that depend predominantly on animal visitors for their dispersal. Since pollinators visit specific sets flowers carry own unique microbiota, we hypothesize plant species visited by the same set may support non‐random microbial communities linked together type pollinator. Here explore importance plant–pollinator interactions in assembly study role geographic location as determinant community composition. We...
The genus Helianthemum, commonly known as rockroses, encompasses 140 species primarily distributed in the Palearctic region, with notable diversification driven by climatic and geological changes. These plants are valuable for studying speciation processes ecological divergence. chemical properties of leaves have also been investigated containing bioactive compounds several therapeutic properties. However, availability genomic resources this almost entirely lacking. Here, we assembled...
Due in part to biophysical sized-related constraints, insects unlike vertebrates are seldom expected act as primary seed dispersers via ingestion of fruits and seeds (endozoochory). The Mediterranean parasitic plant Cytinus hypocistis, however, possesses some characteristics that may facilitate endozoochory by beetles. By combining a long-term field study with experimental manipulation, we tested whether C. hypocistis endozoochorously dispersed Field studies were carried out over 4 years on...
Flowers offer favourable microenvironments for yeast growth, and are increasingly recognised as a rich source of novel species. Independent surveys yeasts associated with flowers pollinators in South Africa led to the discovery 38 strains two new Physiological profiles analysis internal transcribed spacer D1/D2 domains large subunit rRNA gene showed that they represent species belong Wickerhamiella clade. We describe nectarea f.a. sp. nov. (type strain EBDCdVSA11-1T, CBS 14162T, NRRL...
Abstract Premise Yeasts are often present in floral nectar and can influence plant fitness directly (independently of pollinators) or indirectly by influencing pollinator visitation behavior. However, few studies have assessed the effect yeasts on reproductive success compared effects across different species, limiting our understanding relative impact direct vs. indirect effects. Methods We inoculated six species field with cosmopolitan yeast Metschnikowia reukaufii to analyze female over 2...
Plants with hermaphrodite flowers risk conflict between male and female sexual function due to close proximity of organs. Heterostyly, a genetic floral polymorphism characterized mainly by reciprocal herkogamy, may reduce this increasing the precision pollen transfer morphs. This organ reciprocity is often associated various ancillary characters heteromorphic incompatibility system. Here we describe morphometrics heterostyly in Plumbago auriculata. Using controlled pollination experiments,...

The widespread use of azole antifungals in medicine and agriculture the resulting long-persistent residues could potentially affect beneficial fungi. However, there is very little information on tolerance non-target environmental fungi to azoles. In this study, we assessed susceptibility diverse plant- insect-associated yeasts from Metschnikowia clade, including several ecologically important species, widely used medical agricultural azoles (epoxiconazole, imazalil, ketoconazole...
Pollen limitation, resource fruit abortion, and predation have all been proposed as factors explaining low set in hermaphroditic plants. We conducted a 5-year study combining field observations pollination experiments to determine the causes of Aristolochia paucinervis, Mediterranean species with specialized system two populations SW Spain. Fruit initiation was markedly low, between 28.6 75.0% flowering stems did not initiate any fruit. In most flowers, number germinated pollen grains less...
One of the most extreme manifestations parasitism is found in genus Cytinus, a holoparasite whose vegetative body reduced to an endophytic system living within its host root. There are two species Cytinus Mediterranean, C. hypocistis and ruber, which parasitize various genera Cistaceae, one characteristic families Mediterranean scrublands. The aim this work describe systems their tissue relationships with host.Roots from five different hosts infected ruber were harvested, examined by...
• Speciation via race formation is an important evolutionary process in parasites, producing changes that favour their development on particular host species. Here, the holoparasitic plant Cytinus, which has diverse species family Cistaceae, been used to study occurrence of such races. Amplified fragment length polymorphism (AFLP) analyses were performed 174 individuals 22 populations parasitizing 10 Cistaceae Western Mediterranean basin. Neighbour-joining, multivariate ordination analyses,...
Olfactory floral signals are significant factors in plant-pollinator mutualisms. Recently, unusual fermentation odours have been described the nectar and flowers of some species. Since yeasts common inhabitants many angiosperms nectars, this raises possibility that may act as causal agents and, therefore, possible intermediate plant signaling to pollinators. A recent field study has reported were quite frequent across three different regions Europe America, where they reached high densities...
Mycorrhizae are widespread mutualistic symbioses crucial for the functioning of terrestrial ecosystems. Not all plants associate with mycorrhizae; most parasitic have been suggested to be nonmycorrhizal because they developed alternative strategies obtain nutrients. In endophytic plants, whose vegetative bodies grow completely inside their mycorrhizal host roots, opportunity establishing a tripartite association seems evident, but information on these systems is lacking. studying natural...
The genus Rosenbergiella is one of the most frequent bacterial inhabitants flowers and a usual member insect microbiota worldwide. To date, there only publicly available genome, corresponding to type strain nectarea (8N4T), which precludes detailed analysis intra-genus phylogenetic relationships. In this study, we obtained draft genomes strains other species validly published date (R. australiborealis, R. collisarenosi epipactidis) 23 additional isolates flower origin. Isolate S61T,...
