Fructan accumulation in plants is considered to be dependent on the genotype, the developmental stage, and the tissue/organ, as well as on the environmental conditions. Highly increased fructan levels have been observed particularly under unfavorable environmental conditions, like frost, drought, and salinity, enabling such “fructan accumulators” to maintain growth and development under harsh ambient conditions. In this chapter, we will summarize the influence of environmental conditions on fructan accumulation in plants. A particular focus will lay on “fructan accumulators” with specialized growth habitats (e.g., arid, cool temperate regions, and exposed coastal sites), which have the great potential to serve as new functional food and resources for numerous fructan-based plant products in our globally changing environment in the near future. Examples of industrial applications for plant-based fructans are reviewed and agronomic perspectives are discussed.
