In nature, no single plant completes its life cycle without encountering environmental stress. When cells surpass stress threshold stimuli, chemically reactive oxygen species (ROS) are generated that can cause oxidative damage or act as signals. Plants have developed numerous ROS-scavenging systems to minimize the cytotoxic effects of ROS. The role sucrosyl oligosaccharides (SOS), including fructans and raffinose family (RFOs), is well established during physiology. They believed important...
Fructans and raffinose family oligosaccharides (RFOs) are the two most important classes of water-soluble carbohydrates in plants. Recent progress is summarized on their metabolism (and regulation) functions plants food (prebiotics, antioxidants). Interest has shifted from classic inulin-type fructans to more complex fructans. Similarly, alternative RFOs were discovered next RFOs. Considerable been made understanding structure-function relationships among different kinds plant fructan...
Recent in vitro, vivo, and theoretical experiments strongly suggest that sugar-(like) molecules counteract oxidative stress by acting as genuine reactive oxygen species (ROS) scavengers. A concept was proposed to include the vacuole a part of cellular antioxidant network. According this view, sugars sugar-like vacuolar compounds work concert with phenolic ‘classic’ cytosolic mechanisms. Among biologically relevant ROS (H2O2, O2·–, ·OH), hydroxyl radicals are most dangerous since there no...

CAZypedia was initiated in 2007 to create a comprehensive, living encyclopedia of the carbohydrate-active enzymes (CAZymes) and associated carbohydrate-binding modules involved synthesis, modification degradation complex carbohydrates. is closely connected with actively curated CAZy database, which provides sequence-based foundation for biochemical, mechanistic structural characterization these diverse proteins. Now celebrating its 10th anniversary online, successful example dynamic,...
Prebiotics such as inulin (Inu)-type fructans and alternative natural sweeteners stevioside (Ste) become more popular food ingredients. Evidence is accumulating that carbohydrates carbohydrate-containing biomolecules can be considered true antioxidants, capable of scavenging reactive oxygen species (ROS). Here, we report on the ROS abilities Inu Ste in comparison with other sugars, sugar derivatives arbutin. It found are superior scavengers both hydroxyl superoxide radicals, effective than...
Abstract Fructans are fructose‐based oligo‐ and polymers that serve as reserve carbohydrates in many plant species. The original Edelman Jefford model for GF n inulin type fructan biosynthesis was confirmed by the de novo synthesis of fructans vitro well heterologous expression respective cDNAs non‐fructan plants. Now can be extended F fructans. Recent progress has now succeeded elucidating biochemistry molecular biology biodegradation chicory, an economically important species used...
Over the past decades, considerable advances have been made in understanding crucial role and regulation of sucrose metabolism plants. Among various sucrose-catabolizing enzymes, alkaline/neutral invertases (A/N-Invs) long remained poorly studied. However, recent findings demonstrated presence A/N-Invs organelles addition to cytosol, their importance for plant development stress tolerance. A cytosolic (At-A/N-InvG, At1g35580) a mitochondrial (At-A/N-InvA, At1g56560) member analysed more...
Sugars do not only act as source of energy, but they also signals in plants. This mini review summarizes the emerging links between sucrose-mediated signaling and cellular networks involved flowering time control defense. Cross-talks with gibberellin (GA) jasmonate (JA) pathways are highlighted. The circadian clock fulfills a crucial role at heart bilateral relation sugar is discussed. It proposed that important factors controlling plant growth (DELLAs, PIFs, invertases trehalose-...
Summary Substantial formation of reactive oxygen species ( ROS ) is inevitable in aerobic life forms. Due to their extremely high reactivity and short lifetime, hydroxyl radicals are a special case, because cells have not developed enzymes detoxify these most dangerous . Thus, scavenging may only occur by accumulation higher levels simple organic compounds. Previous studies demonstrated that plant‐derived sugars show radical capabilities during Fenton reactions with Fe 2+ hydrogen peroxide...
Elevated CO2 concentrations and extreme climate events, are two increasing components of the ongoing global climatic change factors, may alter plant chemical composition thereby their economic ecological characteristics, e.g. nutritional quality decomposition rates. To investigate impact extremes on tissue quality, four temperate grassland species: fructan accumulating grasses Lolium perenne, Poa pratensis, nitrogen (N) fixing legumes Medicago lupulina Lotus corniculatus were subjected to...
