Summary Plant lodging resistance is an important integrative agronomic trait of grain yield and quality in crops. Although extensin proteins are tightly associated with plant cell growth wall construction, little has yet been reported about their impacts on resistance. In this study, we isolated a novel extensin‐like (Os EXTL ) gene rice, selected transgenic rice plants that expressed Os under driven two distinct promoters. Despite different expression levels, two‐promoter‐driven ‐transgenic...
Biomass recalcitrance and plant lodging are two complex traits that tightly associate with cell wall structure features. Although genetic modification of walls can potentially reduce for enhancing biomass saccharification, it remains a challenge to maintain normal growth enhanced yield resistance in transgenic plants. Sucrose synthase (SUS) is key enzyme regulate carbon partitioning by providing UDP-glucose as substrate cellulose other polysaccharide biosynthesis. SUS plants have reportedly...
Cellulose is an abundant biopolymer and a prominent constituent of plant cell walls. also central component to morphogenesis contributes the bulk plant's biomass. While cellulose synthase (CesA) genes were identified over two decades ago, genetic manipulation this family enhance production has remained difficult. In study, we show that increasing expression levels three primary wall AtCesA6-like (AtCesA2, AtCesA5, AtCesA6), but not AtCesA3, AtCesA9 or secondary AtCesA7, can promote major...
Auxin signaling provides a promising approach to controlling root system architecture and improving stress tolerance in plants. However, how the auxin is transducted this process remains unclear. The Aux indole-3-acetic acid (IAA) repressor IAA17.1 stabilized by salinity, primarily expressed lateral (LR) primordia tips poplar. Overexpression of auxin-resistant form (IAA17.1m) led growth inhibition LRs, markedly reduced salt tolerance, increased reactive oxygen species (ROS) levels, decreased...
Ferulate 5-hydroxylase (F5H) is a limiting enzyme involved in biosynthesizing sinapyl (S) monolignol angiosperms. Genetic regulation of F5H can influence S synthesis and therefore improve saccharification efficiency biofuel production. To date, little known about whether post-transcriptionally regulated by endogenous microRNAs (miRNAs) woody plants. Here, we report that microRNA, miR6443, specifically regulates lignin biosynthesis during stem development Populus tomentosa. In situ...
Grain size and weight are two important determinants of grain yield in rice. Although overexpression sucrose synthase (SUS) genes has led to several improvements on cellulose starch-based traits transgenic crops, little is reported about SUS enhancement hull In this study, we selected rice plants that overexpressed OsSUS1-6 driven with the maize Ubi promoter. Compared controls (wild type empty vector line), all independent OsSUS homozygous lines exhibited considerably increased weights....
Abstract Background As a leading biomass feedstock, poplar plants provide enormous lignocellulose resource convertible for biofuels and bio-chemicals. However, recalcitrance particularly in wood plants, basically causes costly bioethanol production unacceptable commercial marketing with potential secondary pollution to the environment. Therefore, it becomes important reduce by genetic modification of plant cell walls, meanwhile establish advanced process technology woody plants....
Abstract Background The recalcitrance of lignocellulosic biomass provided technical and economic challenges in the current conversion processes. Lignin is considered as a crucial component utilization. An in-depth understanding lignin biosynthesis can provide clues to overcoming recalcitrance. Laccases are believed play role oxidation monomers, leading formation higher-order lignin. In plants, functions only few laccases have been evaluated, so little known about effect on cell wall...
CSLD3, a gene of the cellulose synthase-like D family, affects root hair elongation, but its interactions with ethylene signaling and phosphate-starvation are poorly understood. Here, we aim to understand role CSLD3 in context phosphate starvation pathways Arabidopsis plant growth. Therefore, performed comparative analysis csld3-1 mutant, CSLD3-overexpressing lines, ethylene-response mutants, such as constitutive mutant i-ctr1. We found that overexpression enhanced hypocotyl growth by...
Woody plants provide the most abundant biomass resource that is convertible for biofuels. Since lignin a crucial recalcitrant factor against lignocellulose hydrolysis, genetic engineering of biosynthesis considered as promising solution. Many MYB transcription factors have been identified to involve in regulation cell wall formation or phenylpropanoid pathway. In previous study, we PtoMYB115 contributes proanthocyanidin pathway, however, little known about its role and saccharification...
Miscanthus is a leading bioenergy candidate for biofuels, and it thus becomes essential to characterize the desire natural germplasm accessions with high biomass saccharification. In this study, total 171 were geographically mapped using public database. According equation [P(H/L| East) = P(H/L∩East)/P(East)], probability (P) parameters calculated on relationships between geographical distributions of in East China, related factors high(H) or low(L) values including saccahrification under 1%...
Lignin and flavonoids play a vital role in the adaption of plants to terrestrial environment. 4-Coumarate: coenzyme A ligase (4CL) is key enzyme general phenylpropanoid metabolism which provides precursors for both lignin biosynthesis. However, very little known about how such essential enzymatic functions evolve diversify. Here, we analyze 4CL sequence variation patterns phylogenetic framework further identify evolutionary forces that lead functional divergence. The results reveal...
