Development of Green Resin Using Solid Waste Protein Soybean Curd “Tofu” Production

open access: yesJournal of Tropical Life Science, 2010
One of the most concerns associated with many commercially available composites is that they used of non-degradable resins and fibers that primarily made using non-degradable, petroleum-based chemicals as feed stock. These conditions will

Plant diseases caused by heavy metals and their phytiatry with cation exchangers

open access: yesActa Agrobotanica, 2015
The noxious influence of heavy metals as lead, zinc, copper and lead on higher plants and soil fungi was described. Addition to the soil of Levatit cation exchangers consisting of polystyrene porous resins, charged with calcium or manganese in granulated

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

open access: yesFEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

A clue on bee glue: New insight into the sources and factors driving resin intake in honeybees (Apis mellifera).

open access: yesPLoS ONE, 2019
Honeybees (Apis mellifera) are threatened by numerous pathogens and parasites. To prevent infections they apply cooperative behavioral defenses, such as allo-grooming and hygiene, or they use antimicrobial plant resin.

Recent Advances in the Chemical Composition of Propolis

open access: yesMolecules, 2014
Propolis is a honeybee product with broad clinical applications. Current literature describes that propolis is collected from plant resins. From a systematic database search, 241 compounds were identified in propolis for the first time between 2000 and ...

Plant basal resistance: genetics, biochemistry, and impacts on plant-biotic interactions [PDF]

open access: yes, 2012
Basal resistance depends largely on a diverse range of defence mechanisms that become active upon attack by pathogens or insects. These mechanisms range from rapid stomatal closure and production of reactive oxygen species, to callose deposition and ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

A review of amber and copal occurrences in Africa and their paleontological significance

open access: yesBSGF - Earth Sciences Bulletin, 2020
The paleontological interest for fossil plant resins (amber and copal) has greatly increased in the last decades, as field studies have resulted in the discovery of various new deposits worldwide.
