trehalose is an important disaccharide signal metabolite in plants which is involved in various aspects of plant function such as response to stress, photosynthesis and carbon allocation and partitioning. a mutant of arabidopsis lacking trehalose-6-phosphate synthase activity (tps1) accumulates ascorbate. exogenous ascorbate application ameliorates trehalose induced growth inhibition of wild ty...

Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA-g-MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLAþ starch blends without a compatibilizer do not...

Saccharification of polysaccharides releases monosaccharides that can be used by ethanol-producing microorganisms in biofuel production. To improve plant biomass as a raw material for saccharification, factors controlling the accumulation and structure of carbohydrates must be identified. Rice SUB1A-1 is a transcription factor that represses the turnover of starch and postpones energy-consuming...

in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...

this study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. starch-based sbr1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (plastograph brabender).the content in starch was varied from 0 to 50 phr. the effect of starch content on the rheological behavior was evaluated through...

gbss protein, that is the product of waxy gene (wx) is one of the major enzyme in starch biosynthesis that controls the proportion of amylose to amylopechtine and its absence leads to production of starch with low amylose and higher amylopechtine content, called waxy starch.wx-a1, wx-b1, wx-d1 are three locuses in bread wheat (triticum aestivum) genome that encodes gbss protein and waxy starch ...

The objective of this study was to evaluate the effects of different concentrations of DL-malate (disodium salt) on the in vitro mixed ruminal microorganism fermentation of soluble starch or cracked corn. Ruminal fluid was collected from a steer fed 6.8 kg of forage and 2.3 kg of concentrate supplement once daily, and mixed ruminal microorganisms were incubated in anaerobic media (40 mL) that c...
