“…Thus, M. lutarioriparius cell wall was classified as type II cell wall (Heaton et al 2010). The occurrence of MLG in type II cell walls has been reported in the cell walls of the leaves of various Poaceae species, such as Lolium multiflorum (Trethewey et al 2005), barley Fincher 2009), rice (Vega-Sánchez et al 2012), and three Miscanthus ecotype seedlings, where MLG content increased during cold acclimation (Domon et al 2013). The trace of MLG, however, was undetectable in the stem of M. lutarioriparius in the present study.…”

Key message Cell wall polysaccharides' occurrences in two internodes of different development stages in M. lutarioriparius stem were analyzed and three major differences between them were identified by cell wall polysaccharide probes. Abstract Deposition and modification of cell wall polysaccharides during stem development affect biomass yield of the Miscanthus energy crop. The distribution patterns of cell wall polysaccharides in the 2nd and the 11th internodes of M. lutarioriparius stem were studied using in situ immunofluorescence assay. Crystalline cellulose and xylan were present in most of the stem tissues except phloem, where xyloglucan was the major composition of hemicellulose. The distribution of pectin polysaccharides varied in stem tissues, particularly in vascular bundle elements. Xylogalacturonan, feruloylated-1,4-b-D-galactan and (1,3)(1,4)-b-glucans, however, were insufficient for antibodies binding in both internodes. Furthermore, the distribution of cell wall polysaccharides was differentiated in the two internodes of M. lutarioriparius. The significant differences in the pattern of occurrence of long 1,5-a-L-arabinan chain, homogalacturonan and fucosylated xyloglucans epitope were detected between the two internodes. In addition, the relationships between probable functions of polysaccharides and their distribution patterns in M. lutarioriparius stem cell wall were discussed, which would be helpful to understand the growth characteristics of Miscanthus and identify potential targets for either modification or degradation.

“…For example, pectin content increases during cold acclimation in oilseed rape (Kubacka-Zębalska and Kacperska, 1999; Solecka et al , 2008), and increases in the degree of methylesterification of pectins and the amounts of homogalacturonan, xylogalacturonan, and highly branched rhamnogalacturonan I has been reported during cold acclimation in a freezing-tolerant pea cultivar (Baldwin et al , 2014). The hemicellulose content and its composition are also influenced by cold acclimation in wheat and Miscanthus (Zabotin et al , 1998; Domon et al , 2013). Cuticular deficiencies under cold conditions induced by mutation of acetyl-CoA carboxylase result in freezing and drought sensitivity (Amid et al , 2012).…”

“…A thorough comparison of the field performance and the physiological and growth response to chilling temperatures was carried out using one M. × giganteus clone and one M. sinensis Goliath clone. M. × giganteus was chosen because it is the most planted and studied Miscanthus genotype, while M. sinensis Goliath has been included in several field trials (Robson et al 2011, Van Hulle et al 2012, Zub et al 2012a, Larsen et al 2013 and physiological studies (Clifton-Brown and Jones 1997, Vargas et al 2002, Zub et al 2012b, Domon et al 2013, Purdy et al 2013). Similar to a report from Denmark (Larsen et al 2013), M. × giganteus was consistently higher yielding than M. sinensis Goliath in a field trial established in Melle, Belgium in 2007 (Muylle et al 2015).…”

A long growing season, mediated by the ability to grow at low temperatures early in the season, can result in higher yields in biomass of crop Miscanthus. In this paper, the chilling tolerance of two highly productive Miscanthus genotypes, the widely planted Miscanthus x giganteus and the Miscanthus sinensis genotype 'Goliath', was studied. Measurements in the field as well as under controlled conditions were combined with the main purpose to create basic comparison tools in order to investigate chilling tolerance in Miscanthus in relation to its field performance. Under field conditions, M. x giganteus was higher yielding and had a faster growth rate early in the growing season. Correspondingly, M. x giganteus displayed a less drastic reduction of the leaf elongation rate and of net photosynthesis under continuous chilling stress conditions in the growth chamber. This was accompanied by higher photochemical quenching and lower nonphotochemical quenching in M. x giganteus than that in M. sinensis 'Goliath' when exposed to chilling temperatures. No evidence of impaired stomatal conductance or increased use of alternative electron sinks was observed under chilling stress. Soluble sugar content markedly increased in both genotypes when grown at 12A degrees C compared to 20A degrees C. The concentration of raffinose showed the largest relative increase at 12A degrees C, possibly serving as a protection against chilling stress. Overall, both genotypes showed high chilling tolerance for C-4 plants, but M. x giganteus performed better than M. sinensis 'Goliath'. This was not due to its capacity to resume growth earlier in the season but rather due to a higher growth rate and higher photosynthetic efficiency at low temperatures
