Journal ArticleDOI
Functional characterization of the switchgrass (Panicum virgatum) R2R3-MYB transcription factor PvMYB4 for improvement of lignocellulosic feedstocks
Hui Shen,Xian-Zhi He,Charleson R. Poovaiah,Charleson R. Poovaiah,Wegi A. Wuddineh,Wegi A. Wuddineh,Junying Ma,David G. J. Mann,David G. J. Mann,Huanzhong Wang,Lisa A. Jackson,Yuhong Tang,C. Neal Stewart,C. Neal Stewart,Fang Chen,Richard A. Dixon +15 more
TL;DR: PVMYB4-OX transgenic switchgrass lines can be used as potential germplasm for improvement of lignocellulosic feedstocks and provide a platform for further understanding gene regulatory networks underlying switchgrass cell wall recalcitrance.
Journal ArticleDOI
Gateway-compatible vectors for high-throughput gene functional analysis in switchgrass (Panicum virgatum L.) and other monocot species
David G. J. Mann,Peter R. LaFayette,Peter R. LaFayette,Laura L. Abercrombie,Laura L. Abercrombie,Zachary R. King,Zachary R. King,Mitra Mazarei,Mitra Mazarei,Mathew C. Halter,Charleson R. Poovaiah,Charleson R. Poovaiah,Holly L. Baxter,Holly L. Baxter,Hui Shen,Richard A. Dixon,Wayne A. Parrott,Wayne A. Parrott,C. Neal Stewart,C. Neal Stewart +19 more
TL;DR: A versatile set of Gateway-compatible destination vectors (termed pANIC) was constructed to be used in monocot plants for transgenic crop improvement and was functionally validated in switchgrass and rice and allows for high-throughput screening of sequences of interest in othermonocot species as well.
Journal ArticleDOI
Enhanced Characteristics of Genetically Modified Switchgrass (Panicum virgatum L.) for High Biofuel Production
Hui Shen,Charleson R. Poovaiah,Charleson R. Poovaiah,Angela Ziebell,Angela Ziebell,Timothy J. Tschaplinski,Sivakumar Pattathil,Sivakumar Pattathil,Erica Gjersing,Erica Gjersing,Nancy L. Engle,Rui Katahira,Rui Katahira,Yunqiao Pu,Yunqiao Pu,Robert W. Sykes,Robert W. Sykes,Fang Chen,Arthur J. Ragauskas,Arthur J. Ragauskas,Jonathan R. Mielenz,Michael G. Hahn,Michael G. Hahn,Mark F. Davis,Mark F. Davis,C. Neal Stewart,C. Neal Stewart,Richard A. Dixon,Richard A. Dixon +28 more
TL;DR: The results have demonstrated that overexpression of PvMYB4, a general transcriptional repressor of the phenylpropanoid/lignin biosynthesis pathway, can lead to very high yield ethanol production through dramatic reduction of recalcitrance.
Journal ArticleDOI
Identification and overexpression of gibberellin 2-oxidase (GA2ox) in switchgrass (Panicum virgatum L.) for improved plant architecture and reduced biomass recalcitrance
Wegi A. Wuddineh,Wegi A. Wuddineh,Mitra Mazarei,Mitra Mazarei,Ji-Yi Zhang,Charleson R. Poovaiah,Charleson R. Poovaiah,David G. J. Mann,David G. J. Mann,Angela Ziebell,Angela Ziebell,Robert W. Sykes,Robert W. Sykes,Mark F. Davis,Mark F. Davis,Michael K. Udvardi,Charles Neal Stewart,Charles Neal Stewart +17 more
TL;DR: The results suggest that overexpression of GA2ox genes in switchgrass is a feasible strategy to improve plant architecture and reduce biomass recalcitrance for biofuel.
Journal ArticleDOI
Altered lignin biosynthesis using biotechnology to improve lignocellulosic biofuel feedstocks.
Charleson R. Poovaiah,Charleson R. Poovaiah,Madhugiri Nageswara-Rao,Madhugiri Nageswara-Rao,Jaya R. Soneji,Holly L. Baxter,Holly L. Baxter,Charles Neal Stewart,Charles Neal Stewart +8 more
TL;DR: This review will recapitulate the knowledge of lignin biosynthesis and discuss how lign in has been modified and the consequences for the host plant.
