“…There is no valid way in which the bi- (or possibly tri-) modal c ( s ) distribution (right) can be transformed to yield even the relative masses of the two components, whereas with an estimate (0.60 ml/g) for the partial specific volume of the solute available, the (average) absolute molecular weights of the two species can be defined from the σ values associated with the peaks and their relative concentrations obtained even without that knowledge. Inulins, widely studied and used, usually have a major component with a molecular weight in the region of 5–6 kDa, sedimentation coefficient s 20,w ~0.7S (Imran et al 2012 ; Azis et al 1999 ). They readily degrade to smaller species, particularly at acidic pH levels (Windfield et al 2003 ).…”

MultiSig is a newly developed mode of analysis of sedimentation equilibrium (SE) experiments in the analytical ultracentrifuge, having the capability of taking advantage of the remarkable precision (~0.1 % of signal) of the principal optical (fringe) system employed, thus supplanting existing methods of analysis through reducing the ‘noise’ level of certain important parameter estimates by up to orders of magnitude. Long-known limitations of the SE method, arising from lack of knowledge of the true fringe number in fringe optics and from the use of unstable numerical algorithms such as numerical differentiation, have been transcended. An approach to data analysis, akin to ‘spatial filtering’, has been developed, and shown by both simulation and practical application to be a powerful aid to the precision with which near-monodisperse systems can be analysed, potentially yielding information on protein-solvent interaction. For oligo- and poly-disperse systems the information returned includes precise average mass distributions over both cell radial and concentration ranges and mass-frequency histograms at fixed radial positions. The application of MultiSig analysis to various complex heterogenous systems and potentially multiply-interacting carbohydrate oligomers is described.

“…Jerusalem artichoke has the ability to tolerate different environmental stress conditions including drought, frost as well as some pests and diseases [Slimestad et al 2010]. This plant is native to north America and is considered to be an important source of inulin [Azis et al 1999, Muir et al 2007] and a good source of alcohol production [Chekroun et al 1996]. Also, Denoroy [1996] indicated that Jerusalem artichoke is a potential source of ethanol because of its high carbohydrate content of tubers and also may be used for inulin production and for energy production in the future [Kim et al 2013.…”

Water shortage is a major problem that limits growth and productivity of plants in arid and semi-arid regions. Protecting plants from adverse environmental conditions by using simple methods could be of great value under these conditions. In the present study, we examined water status and drought tolerance of snap bean, a drought-sensitive plant, and Jerusalem artichoke, a relatively drought tolerant plant in response to the application of salicylic acid (SA). Different levels of SA were applied and several physiological, growth, productivity and quality parameters were recorded together with the relative water content. Foliar application of SA improved growth, productivity, quality as well as some physiological parameters of snap bean and Jerusalem artichoke plants exposed to drought stress. Total chlorophyll content and relative water content were higher in plants treated with SA compared to control plants when subjected to drought stress. The specific responses of snap bean and Jerusalem artichoke to SA under drought stress as well as the possible explanations of the effects of SA are discussed.
