“…In contrast, the APX activity tended to decrease when solar radiation and temperature decreased (in cloudy days) in the control treatment. Such outcomes are different from other studies showing that high solar radiation promoted fructose accumulation in L. multiflorum plants (Sandrin et al 2013) and that high temperatures caused reduction on APX activity in field-grown beech trees (Peltzer and Polle 2001). Interestingly, temperature and solar radiation increase throughout the day practically did not change fructose and fructan contents in plants exposed to both ozone and filtered air, whereas the APX activity increased along the day in plants exposed to filtered air during winter.…”

Ozone (O3) is the most abundant tropospheric oxidant as well as an important component of photochemical pollution. Once inside the plant, ozone can produce reactive oxygen species that change the antioxidative pool and the carbohydrate metabolism. The current study aimed to analyze whether the contents and the composition of the fructan, the ascorbate peroxidase activity, and the H2O2 accumulation were changed in Lolium multiflorum ssp. italicum cv. Lema plants as response to short-term exposure to ozone and/or to different meteorological conditions, in two contrasting seasons (winter and summer). Results showed that higher solar radiation tends to decrease fructose content and, along with temperature, increases the ascorbate peroxidase (APX) activity. Such activity and levels of fructans practically did not vary during the time the experiment was being done, but APX daylight variation was modified by the ozone. Thus, the higher levels of this pollutant decreased the APX activity and increased fructose content, as well as changed the size of the fructan chains. Hydrogen peroxide (H2O2) accumulation was higher in plants that were fumigated with ozone when compared to the control, and it decreased throughout the day. As a conclusion, fructan contents increased when the APX activity decreased. It suggested that fructans could also help the defense system when there is a reduction on the APX activity in the plant.

“…Lolium species are often used as a model plant for fructan research (Lasseur et al, , ; Lothier, Van Laere, Prud'homme, Van den Ende, & Morvan‐Bertrand, ), and the effects of other types of stresses have been documented. Lasseur et al () showed a stronger induction in FT activity and gene expression in L. perenne exposed to frequent defoliation, whereas Sandrin, Figueiredo‐Ribeiro, Delitti, and Domingos () linked daily oscillations in fructan content with tolerance to changes in weather and air pollution in Lolium multiflorum . Interestingly, although fructans are often associated with drought tolerance, Albrecht, Biemelt, and Baumgartner () showed an increase in fructan content in response to flooding.…”

Fructans are multifunctional fructose-based water soluble carbohydrates found in all biological kingdoms but not in animals. Most research has focused on plant and microbial fructans and has received a growing interest because of their practical applications. Nevertheless, the origin of fructan production, the so-called "fructan syndrome," is still unknown. Why fructans only occur in a limited number of plant and microbial species remains unclear. In this review, we provide an overview of plant and microbial fructan research with a focus on fructans as an adaptation to the environment and their role in (a)biotic stress tolerance. The taxonomical and biogeographical distribution of fructans in both kingdoms is discussed and linked (where possible) to environmental factors. Overall, the fructan syndrome may be related to water scarcity and differences in physicochemical properties, for instance, water retaining characteristics, at least partially explain why different fructan types with different branching levels are found in different species.Although a close correlation between environmental stresses and fructan production is quite clear in plants, this link seems to be missing in microbes. We hypothesize that this can be at least partially explained by differential evolutionary timeframes for plants and microbes, combined with potential redundancy effects.

“…Due to its importance in agriculture, the composition and genetics of annual ryegrass have been extensively studied. In addition to its widespread agricultural use, Lolium ryegrass is frequently used for both field and laboratory research to investigate endophytes phytoremediation, pollutant uptake and toxicity, − morphological responses, herbicide resistance and studies of plasma membranes and associated enzymes such as glucan synthases. , …”

The development of deuterated biomass is essential for effective neutron scattering studies on biomass, which can provide key insights into the complex biomass conversion processes. A method for optimized production of deuterated annual ryegrass (Lolium multiflorum) was developed by growing the plants in 50% D2O in perfused hydroponic chambers. Deuterium incorporation of 36.9% was found in the annual rye grown in 50% D2O. Further, deuterium incorporation of 60% was achieved by germinating the rye seedlings in H2O and growing in 50% D2O inside the perfusion chambers. The characteristics related to enzymatic hydrolysis such as biomass composition, degree of polymerization, and cellulose crystallinity were compared with its control protiated counterpart. The cellulose molecular weight indicated slight variation while hemicellulose molecular weights and cellulose crystallinity remain unaffected with the deuteration.
