Nanhu News Network (correspondent Wu Leiming and He Boyang) Recently, the research group of Associate Professor Xia Tao from the biomass and bioenergy team of our school integrated the genetic improvement of crops and yeast, and the green optimization of the biomass conversion process, and proposed the efficient and green resource utilization of crop stalks.
Crop straw biomass is a promising renewable resource.
Cellulose is the main component of biomass, and its high degree of crystallization and polymerization are the key limiting factors for enzymatic saccharification of biomass.
Observation of phenotype and microfibril nanostructure of OsMYB103L mutant and transgenic plants
Traditional Saccharomyces cerevisiae has low xylose metabolism, and the effective utilization of xylose has become a bottleneck problem in the efficient conversion of lignocellulosic biomass
Recombinant Saccharomyces cerevisiae model diagram of efficient use of xylose and glucose to produce ethanol
Associate Professor Xia Tao from the School of Life Science and Technology is the corresponding author of the two articles.

Background: As a major component of plant cell walls, cellulose provides the most abundant biomass resource convertible for biofuels.
Results: In this study, we identified a novel rice mutant (Osfc9/myb103) encoded a R2R3-MYB transcription factor, and meanwhile generated OsMYB103L-RNAi-silenced transgenic lines.
Conclusions: This study has demonstrated that down-regulation of OsMYB103L could specifically improve cellulose features and cellulose nanofibers assembly to significantly enhance biomass enzymatic saccharification under green-like and mild chemical pretreatments in rice.

Cellulosic ethanol has been regarded as excellent additive into petrol fuels for reduced net carbon release, and yeast fermentation is thus a crucial step for bioethanol production.
