Fructan and its relationship to abiotic stress tolerance in plants

Numerous studies have been published that attempted to correlate fructan concentrations with freezing and drought tolerance. Studies investigating the effect of fructan on liposomes indicated that a direct interaction between membranes and fructan was possible. This new area of research began to move fructan and its association with stress beyond mere correlation by confirming that fructan has the capacity to stabilize membranes during drying by inserting at least part of the polysaccharide into the lipid headgroup region of the membrane. This helps prevent leakage when water is removed from the system either during freezing or drought. When plants were transformed with the ability to synthesize fructan, a concomitant increase in drought and/or freezing tolerance was confirmed. These experiments indicate that besides an indirect effect of supplying tissues with hexose sugars, fructan has a direct protective effect that can be demonstrated by both model systems and genetic transformation

Like mixing oil and water?: the take up of sustainability in hard-to-reach places - an East Texas case study

Following studies about the adoption of sustainability initiatives in both innovative and ordinary US cities, this article offers a unique view of sustainability in hard-to-reach places where regulation and planning are viewed with suspicion. Taking an interpretive approach to policy analysis, the paper asks if hard-to-reach places are destined to remain untouched by what many argue is a central tenet of modern planning. In so doing, it offers a key point of contrast to studies on cities at the vanguard of change, reminding us how critical it is to recognise all types of communities in our research and practice
