Abstract Glucosinolates are natural plant products that function in the defense toward herbivores and pathogens. Plant is regulated by multiple signal transduction pathways which salicylic acid (SA), jasmonic acid, ethylene as signaling molecules. Glucosinolate content was analyzed Arabidopsis wild-type plants response to single or combinatorial treatments with methyljasmonate (MeJA), 2,6-dichloro-isonicotinic ethylene, 2,4-dichloro-phenoxyacetic wounding. In addition, several mutants...
The rab17 gene from maize is transcribed in late embryonic development and responsive to abscisic acid water stress embryo vegetative tissues. In vivo footprinting transient transformation of were performed embryos tissues characterize the cis ‐elements involved regulation gene. By footprinting, protein binding was observed nine elements promoter, which correspond five putative ABREs (abscisic elements) four other sequences. footprints indicated that distinct proteins interact with these two...
Lignin is known to hinder efficient enzymatic conversion of lignocellulose in biorefining processes. In particular, nonproductive adsorption cellulases onto lignin considered a key mechanism explain how retards cellulose extended reactions. Lignin-rich residues (LRRs) were prepared via extensive degradation corn stover (Zea mays subsp. L.), Miscanthus × giganteus stalks (MS) and wheat straw (Triticum aestivum L.) (WS) samples that each had been hydrothermally pretreated at three severity...
Abstract The chemical characteristics of wheat straw lignin pretreated under dilute acid conditions were compared. After pretreatment, the content solid residue increased as temperature (from 160°C to 190°C) and with amount added (0%, 0.25%, or 1% H 2 SO 4 ). Pretreatment at 190°C increasing concentrations catalyst led a decrease in glucan content, whereas remained almost constant pretreatment regardless concentration. xylan decreased proportion concentration temperature. residual lignins...
Understanding factors that govern lignocellulosic biomass recalcitrance is a prerequisite for designing efficient 2nd generation biorefining processes. However, the reasons and mechanisms responsible quantitative differences in enzymatic digestibility of various feedstocks response to hydrothermal pretreatment at different severities are still not sufficiently understood. Potentially important biorefining, corn stover (Zea mays subsp. L.), stalks Miscanthus × giganteus, wheat straw (Triticum...
Abstract Understanding of how the plant cell walls different species respond to pretreatment can help improve saccharification in bioconversion processes. Here, we studied chemical and structural modifications lignin hemicellulose hydrothermally pretreated poplar wheat straw using wet chemistry 2D heteronuclear single quantum coherence nuclear magnetic resonance (NMR) their effects on cellulose conversion. Increased severity reduced levels β─O─4 linkages with concomitant relatively increased...
After hydrothermal pretreatment and enzymatic hydrolysis of wheat straw, a slurry rich in lignin but with high content inorganic substances, especially silica, residual carbohydrates is produced. This was used to develop an ethanol organosolv separation method produce silica-free fractions. The addition para toluene sulphonic acid (PTSA) the use two alternative long-chain alcohols, oleyl alcohol or nonylphenol, were tested. In every reaction, fractions produced their molecular size elemental...
