“…GolS protein sequences were identified to include Glyco_transf_8 (PF01501) domain structure and have a very close molecular weight (36.40-39.59 kDa) and amino acid length (318-347 amino acids) with a slightly acidic pI value of 5.35-6.40. Similar results were also reported in different plant species, including cotton (Zhou et al, 2012), Coffea arabica (dos Santos et al, 2011) and tomato (Downie et al, 2003). Sub-cellular locations of GolSs were mainly predicted as cytoplasmic.…”

“…Also, monocot GolS proteins were clustered in subgroup B with the high bootstrap value (99%) and this monocot clade was observed in previous studies (dos Santos et al, 2011;Sengupta et al, 2012;Zhou et al, 2014). Arabidopsis GolS1 and GolS2 were induced by drought, salt and heat stress while Arabidopsis GolS2 was induced by cold stress (Taji et al, 2002).…”

“…The expression of ZmGOLS2, which encodes tissue responses to dehydration stress, is positively correlated with myo-inositol concentrations (Zhao et al 2004b). Numerous copies of GolS genes, which were detected in vegetative tissues of Arabidopsis thaliana (Nishizawa et al 2008), Salvia miltiorrhiza (Wang et al 2012) and Coffea arabica (Dos Santos et al 2011), are specifically expressed in response to abiotic stressors such as salinification, cold, dehydration and soil drought. Increased expression of GolS genes intensifies the accumulation of galactinol and raffinose in tissues and increases plant resistance to stress (Wang et al 2012;Zhuo et al 2013).…”

The accumulation of soluble carbohydrates in maturing diaspores of flowering plants comprising Arctic populations of Cerastium alpinum, indigenous Antarctic species Colobanthus quitensis and Deschampsia antarctica, and cosmopolitan Poa annua from the Antarctic was investigated. For comparative purposes, the diaspores of two species of flowering plants growing in the area of Olsztyn (Poland), Poa annua (Poaceae) and Cerastium arvense (Caryophyllaceae) were used. A qualitative and quantitative analysis of soluble carbohydrates conducted by means of high-resolution gas chromatography showed that monosaccharides (glucose and fructose), maltose and sucrose, raffinose, myo-inositol and galactinol are ubiquitous in developing and mature diaspores among investigated species. Moreover, D. antarctica and P. annua caryopses additionally contained stachyose and 1-kestose; the seeds of Caryophyllaceae studied were found to contain D-pinitol and D-ononitol. The development and maturation of the seeds of polar Caryophyllaceae and Poaceae were accompanied by the changes in the concentration of their soluble carbohydrates. During maturation, seeds accumulated galactinol and raffinose family of oligosaccharides (RFOs), except C. quitensis. Although seeds of the studied Caryophyllaceae contained D-pinitol and lower amounts of D-ononitol, they did not accumulate a-D-galactoside derivatives of mentioned cyclitols. P. annua caryopses, occurring in the Antarctic, were found to accumulate considerably higher amounts of sucrose and 1-kestose than those developed in Olsztyn.

ORCID IDs: 0000-0003-3830-0415 (J.-G.H.); 0000-0001-5248-9096 (M.B.).Nonstructural carbohydrates (NSCs) play a crucial role in xylem formation and represent, with water, the main constraint to plant growth. We assessed the relationships between xylogenesis and NSCs in order to (1) verify the variance explained by NSCs and (2) determine the influence of intrinsic (tissue supplying carbon) and extrinsic (water availability and temperature) factors. During 2 years, wood formation was monitored in saplings of black spruce (Picea mariana) subjected to a dry period of about 1 month in June and exposed to different temperature treatments in a greenhouse. In parallel, NSC concentrations were determined by extracting the sugar compounds from two tissues (cambium and inner xylem), both potentially supplying carbon for wood formation. A mixed-effect model was used to assess and quantify the potential relationships. Total xylem cells, illustrating meristematic activity, were modeled as a function of water, sucrose, and D-pinitol (conditional r 2 of 0.79). Water availability was ranked as the most important factor explaining total xylem cell production, while the contribution of carbon was lower. Cambium stopped dividing under water deficit, probably to limit the number of cells remaining in differentiation without an adequate amount of water. By contrast, carbon factors were ranked as most important in explaining the variation in living cells (conditional r 2 of 0.49), highlighting the functional needs during xylem development, followed by the tissue supplying the NSCs (cambium) and water availability. This study precisely demonstrates the role of carbon and water in structural growth expressed as meristematic activity and tissue formation.
