Galactinol synthase transcriptional profile in two genotypes of Coffea canephora with contrasting tolerance to drought

Genetics and Molecular Biology, 2015
Increased synthesis of galactinol and raffinose family oligosaccharides (RFOs) has been reported in vegetative tissues in response to a range of abiotic stresses.

NMR Identification and Quantification of Galactinol in Green Coffea arabica: Implications for Traceability and Adulteration. [PDF]

J Food Sci
ABSTRACT Among coffee low‐molecular‐weight carbohydrates, galactinol plays an important role in coffee physiology and quality, having received attention also for its potential use as a marker of geographical origin. Nevertheless, data on the occurrence of this sugar in green coffee beans remain limited.

Isolation and characterization of hybrid poplar galactinol synthases [PDF]

BMC Proceedings, 2011
The raffinose family of oligosaccharides (RFOs) likely fulfill at least few major physiological roles in plants, translocation of carbon in the phloem, storage in sink tissues, and as putative biological agents to combat both abiotic and biotic stress [1-3].

Comparative Analysis of the Transcriptomes of Persisting and Abscised Fruitlets: Insights into Plant Hormone and Carbohydrate Metabolism Regulated Self-Thinning of Pecan Fruitlets during the Early Stage

Current Issues in Molecular Biology, 2021
Pecan is one of the most popular nut species in the world. The fruit drop rate of the pecan ‘Pawnee’ is more than 57%, with four fruit drop stages, which is very serious.

Galactinol Synthase Gene Expression in Melon [PDF]

Journal of the American Society for Horticultural Science, 2003
Raffinose family oligosaccharides (RFOs) perform several physiological functions in plants. In addition to accumulating during seed formation, raffinose and stachyose are translocated in the phloem and may accumulate in response to low temperatures, drought, or salt stress.

Comprehensive analysis of the GALACTINOL SYNTHASE (GolS) gene family in citrus and the function of CsGolS6 in stress tolerance.

PLoS ONE, 2022
Galactinol synthase (GolS) catalyzes the first and rate-limiting step in the synthesis of raffinose family of oligosaccharides (RFOs), which serve as storage and transport sugars, signal transducers, compatible solutes and antioxidants in higher plants ...

Isolation and characterization of galactinol synthases from hybrid poplar [PDF]

Journal of Experimental Botany, 2011
The raffinose family of oligosaccharides (RFOs) serve as transport carbohydrates in the phloem, storage compounds in sink tissues, and putative biological agents to combat both abiotic and biotic stress in several plant species. To investigate further the functional roles of this class of compounds in trees, two cDNAs encoding galactinol synthase (GolS,

Galactinol Is a Signaling Component of the Induced Systemic Resistance Caused by Pseudomonas chlororaphis O6 Root Colonization

Molecular Plant-Microbe Interactions, 2008
Root colonization by Pseudomonas chlororaphis O6 in cucumber elicited an induced systemic resistance (ISR) against Corynespora cassiicola. In order to gain insight into O6-mediated ISR, a suppressive subtractive hybridization technique was applied and ...

From Raffinose Family Oligosaccharides to Sucrose and Hexoses: Gene Expression Profiles Underlying Host-to-Nematode Carbon Delivery in Cucumis sativus Roots

Frontiers in Plant Science, 2022
Root-knot nematodes (Meloidogyne incognita) induce specific feeding sites in cucumber roots where they absorb carbon nutrients from the host, thereby turning the feeding sites into a strong sink for assimilates.

Molecular cloning of a seed specific multifunctional RFO synthase/ galactosylhydrolase in Arabidopsis thaliana

Frontiers in Plant Science, 2015
Stachyose is among the raffinose family oligosaccharides one of the major water-soluble carbohydrates next to sucrose in seeds of a number of plant species. Especially in leguminous seeds, e.g. chickpea, stachyose is reported as the major component.
