The Application of Pollen as a Functional Food and Feed Ingredient—The Present and Perspectives

open access: yesBiomolecules, 2020
Pollen is recognized as an excellent dietary supplement for human nutrition, which is why it can be found in different forms on the market (granules, capsules, tablets, pellets, and powders).

Land use and pollinator dependency drives global patterns of pollen limitation in the Anthropocene

open access: yesNature Communications, 2020
Land use change, by disrupting the co-evolved interactions between plants and their pollinators, could be causing plant reproduction to be limited by pollen supply.

The rising tide of photographs: Not drowning but waving?

open access: yesCaptures, 2016
Concerns about the huge quantities of photographs circulating in digital networks have led some to proclaim that we are now drowning in images. This article surveys these anxieties by examining the work of artists who use photography’s scale, and ...

Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

open access: yesThe EuroBiotech Journal, 2019
Microspore embryogenesis is a model system of plant cell reprogramming, totipotency acquisition, stress response and embryogenesis initiation. This in vitro system constitutes an important biotechnological tool for haploid and doubled-haploid plant ...

Pollen Sporoplasts: Dissolution of Pollen Walls [PDF]

open access: yesPlant Physiology, 1985
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees

Pectin De-methylesterification and AGP Increase Promote Cell Wall Remodeling and Are Required During Somatic Embryogenesis of Quercus suber

open access: yesFrontiers in Plant Science, 2019
Somatic embryogenesis is a reliable system for in vitro plant regeneration, with biotechnological applications in trees, but the regulating mechanisms are largely unknown.

Birch pollen allergy in Europe

open access: yesAllergy. European Journal of Allergy and Clinical Immunology, 2019
Birch and other related trees of the families Betulaceae and Fagaceae (alder, hazel, oak, hornbeam, chestnut, and beech) constitute the birch homologous group. This grouping is primarily based on the extensive IgE cross‐reactivity of allergen homologs to

Functional expression and subcellular localization of pea polymorphic isoflavone synthase CYP93C18

open access: yesBiologia Plantarum, 2013
Isoflavone synthase (IFS; CYP93C) plays a key role in the biosynthesis of phenolic secondary metabolites, isoflavonoids. These compounds, which are well-known for their benefits to human health and plant defence, are produced mostly in legumes.

Assessment of Pollen Viability for Wheat

open access: yesFrontiers in Plant Science, 2020
Wheat sheds tricellular short-lived pollen at maturity. The identification of viable pollen required for high seed set is important for breeders and conservators.
