“…Hence, there are efforts focused on reducing the RFO content in crop seeds (Dierking and Bilyeu, 2008;Yang et al, 2015). By contrast, RFOs are an important energy resource for beneficial microflora in the small intestine (Rada et al, 2008;Grmanova et al, 2010). Understanding the metabolic pathway of RFOs and their physiological function would assist researchers to manipulate RFOs in crop plants for fulfilling these multifarious goals.…”

Raffinose family oligosaccharides (RFOs) accumulate in seeds during maturation desiccation in many plant species. However, it remains unclear whether RFOs have a role in establishing seed vigor. GALACTINOL SYNTHASE (GOLS), RAFFINOSE SYNTHASE (RS), and STACHYOSE SYNTHASE (STS) are the enzymes responsible for RFO biosynthesis in plants. Interestingly, only raffinose is detected in maize seeds, and a unique maize RS gene (ZmRS) was identified. In this study, we found that two independent mutator (Mu)-interrupted zmrs lines, containing no raffinose but hyperaccumulating galactinol, have significantly reduced seed vigor, compared with null segregant controls. Unlike maize, Arabidopsis thaliana seeds contain several RFOs (raffinose, stachyose, and verbascose). Manipulation of A. thaliana RFO content by overexpressing ZmGOLS2, ZmRS, or AtSTS demonstrated that co-overexpression of ZmGOLS2 and ZmRS, or overexpression of ZmGOLS2 alone, significantly increased the total content of RFOs and enhanced Arabidopsis seed vigor. Surprisingly, while overexpression of ZmRS increased seed raffinose content, its overexpression dramatically decreased seed vigor and reduced the seed amounts of galactinol, stachyose, and verbascose. In contrast, the atrs5 mutant seeds are similar to those of the wild type with regard to seed vigor and RFO content, except for stachyose, which accumulated in atrs5 seeds. Total RFOs, RFO/sucrose ratio, but not absolute individual RFO amounts, positively correlated with A. thaliana seed vigor, to which stachyose and verbascose contribute more than raffinose. Taken together, these results provide new insights into regulatory mechanisms of seed vigor and reveal distinct requirement for RFOs in modulating seed vigor in a monocot and a dicot.

“…Previous studies show that soybean holds high content of the stachyose, and it was identified as the exclusive source of stachyose (Grmanová et al 2010). However, through our designed protocal, stachyose could be extracted from yinmiao, and the yield of stachyose is 46.99% by RSM.…”

“…However, stachyose is proved to be a prebiotics (Gibson and Roberfroid 1995;Seo et al 2007;Rabelo et al 2009), which can stimulate the growth of bifidobacteria in the human and animal intestine and protect the function of organs by eliminating harmful substances (Grmanová et al 2010;Rada et al 2002 andLiying et al 2003). It is also regarded as a potential substitute for sugar in diabetes patients (Yin et al 2006;Zhang et al 2004).…”

Stachys floridana schuttl. E x benth, also named yinmiao, is a special and traditional Chinese vegetable that is usually used by some diabetes patients as a pharmaceutical plant for its high content of stachyose. Due to the lower cost and higher economic reward, Stachys floridana schuttl. Ex benth is a potentially new source to extract stachyose in the medicine and food industry. Here we optimized the extraction of stachyose from Stachys floridana schuttl. Ex benth by response surface methodology, the yeild can reach as high as up to 47.0% of stachyose at temperature of 60°C, extraction time of 40 min, ethanol volume of 60% and ratio of solid-liquid at 1:10. Our primary result holds great promising for Stachys floridana schuttl. Ex bent extracting industry as well as diabetic medicine.

“…Nevertheless, not all studies report unequivocal positive results of in-feed prebiotics, even under stress conditions such as Eimeria challenge (Faber et al, 2012). Grmanova et al (2010) stated that chicken feed mixtures naturally contain prebiotic oligosaccharides in the form of RFOs in higher concentrations than what is commonly recommended as artificial supplementation. Thus, inconsistency of results obtained in different trials with different prebiotic supplements may depend on the combination of other ingredients in the feed formula.…”

Dysbiosis or dysbacteriosis is defined as a shift in the intestinal microbiota composition resulting in an imbalance between beneficial and harmful bacteria. Since the ban on the use of growth-promoting antibiotics in animal feed in the EU, dysbiosis has emerged as a major problem in intensive animal production. Prebiotics and probiotics are currently under investigation as possible alternatives to growth-promoting antibiotics, as their mode of action is thought to be based largely on a modulation of the composition and function of the intestinal microbiota. In this review, we analyse the currently available data from both animal and human nutrition that document the potential and limitations of prebiotics and probiotics for the control of dysbiosis. An impressive number of empirical feeding trials have been carried out in healthy animals, yielding sometimes contradictory results. More indepth studies have revealed the complexity of the interactions taking place in the lower intestinal tract, thus illustrating that preand probiotics cannot be a simple replacement for growth-promoting antibiotics. Although there are indications that the strategic use of pre-and probiotics can provide major benefits, there is still a lack of basic knowledge on the delicate interactions between the microbiota, the host and the feed components, which hampers the widespread use of these valuable feed additives.
