Bumble Bees and Honey Bees on Islands Harbour Reduced Viral Species Richness, Yet Honey Bee Populations Are Dominated by a Deformed Wing Virus Recombinant

Molecular Ecology, EarlyView.
ABSTRACT Pollinators harbour diverse RNA viromes that play a vital role in their health. Yet, factors that shape viral communities are often unclear. The European honey bee (Apis mellifera) is experiencing a viral epidemic since the emergence of the parasitic mite Varroa destructor (varroa) introduced vector‐borne transmission, which has also been ...

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees

New Phytologist, EarlyView.
Summary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Overexpression of a Tonoplast Malate Transporter Gene Leads to Enhanced Anthocyanin Biosynthesis in Apple

Plant Biotechnology Journal, EarlyView.
ABSTRACT Anthocyanins, a group of secondary metabolites synthesised in the phenylpropanoid pathway, largely determine the peel colour of fleshy fruits, but it is not known if their synthesis is linked to vacuolar malate accumulation that underlies fruit acidity.

S‐Methyl‐l‐Cysteine Sulfoxide: A Hidden Layer of Defences Against Herbivorous Insects in Brassicaceae

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants defend themselves against herbivorous insects through diverse morphological and biochemical traits. Non‐protein amino acids (NPAAs) are an important component of the plant metabolome, although their defensive function remains largely unexplored.

Influence of drought stress on the metabolite and ion composition in nectar and nectaries of different day‐ and night‐flowering Nicotiana species

Plant Biology, EarlyView.
Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Bract size affects resource availability and fruit set in a hummingbird‐pollinated plant with distyly polymorphism

Plant Biology, EarlyView.
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The
