Mass-flowering crops enhance wild bee abundance.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Although agricultural habitats can provide enormous amounts of food resources for pollinator species, links between agricultural and (semi-)natural habitats through dispersal and foraging movements have hardly been studied. In 67 study sites, we assessed the interactions between mass-flowering

Labyrinths, columns and cavities: new internal features of pollen grain walls in the Acanthaceae detected by FIB-SEM.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

External pollen grain morphology has been widely used in the taxonomy and systematics of flowering plants, especially the Acanthaceae which are noted for pollen diversity. However internal pollen wall features have received far less attention due to the difficulty of examining the wall structure.

Wild bees of Grand Staircase-Escalante National Monument: richness, abundance, and spatio-temporal beta-diversity.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Interest in bees has grown dramatically in recent years in light of several studies that have reported widespread declines in bees and other pollinators. Investigating declines in wild bees can be difficult, however, due to the lack of faunal surveys that provide baseline data of bee richness and

C/D class MADS box genes from two monocots, orchid (Oncidium Gower Ramsey) and lily (Lilium longiflorum), exhibit different effects on floral transition and formation in Arabidopsis thaliana.

Prijava / prijava

We have characterized three C/D class MADS box genes from an orchid (Oncidium Gower Ramsey) and a lily (Lilium longiflorum). OMADS4 of orchid and LMADS10 of lily are C class gene orthologs, whereas OMADS2 of orchid is a putative D class gene ortholog. The identity of these three genes is further

Rain pollination provides reproductive assurance in a deceptive orchid.

Prijava / prijava

OBJECTIVE Abiotic pollination by wind or water is well established in flowering plants. In some species pollination by rain splashes, a condition known as ombrophily, has been proposed as a floral strategy. However, evidence for this type of abiotic pollination has remained controversial and many

Pollination: self-fertilization strategy in an orchid.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Mating in flowering plants normally relies on animals, wind, gravity or secretion to convey pollen grains from the male (anther) to the female (stigma) organ. Here we describe a new type of self-pollination mechanism in the tree-living orchid Holcoglossum amesianum, in which the bisexual flower

Morphological and molecular identification of the metacestode parasitizing the liver of rodent hosts in bamboo growing areas of mizoram, northeast India.

Prijava / prijava

In Mizoram (Northeast India), rodent outbreaks are known to occur periodically with the onset of bamboo flowering causing a tremendous destruction to food grains and as per the folk belief, often resulting in famine. In an exploratory survey of rodent pests in bamboo growing atreas for their

[Salvia officinalis l. I. Botanic characteristics, composition, use and cultivation].

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Salvia officinalis L. is an essential oil containing plant, which does not wildly grow in the territories of the Czech and Slovak Republics but it can be successfully cultivated. It is a perennial half-shrub, from which non-flowering herbaceous sprouts or leaves are collected for pharmaceutical

Assessment of Genetic Variation in Apis nigrocincta (Hymenoptera: Apidae) in Sulawesi Revealed by Partial Mitochondrial Cytochrome Oxidase I Gene Sequences.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Asian cavity-nesting honey bee Apis nigrocincta, a native bee species from Sulawesi and the Philippines, plays a vital role in pollinating flowering plants in local ecosystem and agriculture. In this study, we assessed the intraspecific genetic variation of A. nigrocincta using the

Crystal structure of the plant epigenetic protein arginine methyltransferase 10.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Protein arginine methyltransferase 10 (PRMT10) is a type I arginine methyltransferase that is essential for regulating flowering time in Arabidopsis thaliana. We present a 2.6 Å resolution crystal structure of A. thaliana PRMT 10 (AtPRMT10) in complex with a reaction product, S-adenosylhomocysteine.

Ligand binding to an Allergenic Lipid Transfer Protein Enhances Conformational Flexibility resulting in an Increase in Susceptibility to Gastroduodenal Proteolysis.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Non-specific lipid transfer proteins (LTPs) are a family of lipid-binding molecules that are widely distributed across flowering plant species, many of which have been identified as allergens. They are highly resistant to simulated gastroduodenal proteolysis, a property that may play a role in

Amborella trichopoda (Amborellaceae) and the evolutionary developmental origins of the angiosperm progamic phase.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

A remarkable number of the defining features of flowering plants are expressed during the life history stage between pollination and fertilization. Hand pollinations of Amborella trichopoda (Amborellaceae) in New Caledonia show that when the stigma is first receptive, the female gametophyte is near

Floral biology of Tropaeolum majus L. and its relation with Astylus variegatus activity (Germar 1824).

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Tropaeolum majus L. (nasturtium) is a culture popularly known by its medicinal, ornamental and culinary utility. This work aimed to evaluate the interaction between Astylus variegatus (Germar 1824) (Coleoptera: Melyridae) and the nasturtium flowers associated to the weeks of flourishing, in order to

The pollination mechanism in Trigonidium obtusum Lindl (Orchidaceae: Maxillariinae): sexual mimicry and trap-flowers.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

The pollination process in Trigonidium obtusum Lindl. (Epidendroideae: Maxillariinae) is documented. The flowers are pollinated by sexually excited drones of Plebeia droryana (Meliponinae). When attempting to copulate either with sepals or petals, these bees slip on the waxy perianth surface and

Cannabinoid synthases and osmoprotective metabolites accumulate in the exudates of Cannabis sativa L. glandular trichomes.

Prijava / prijava

Cannabinoids are terpenophenolic compounds produced by Cannabis sativa L., which accumulate in storage cavities of glandular trichomes as a part of the exudates. We investigated if tetrahydrocannabinolic acid synthase and cannabidiolic acid synthase, which are involved in the last step of
