Gene Details:

• Gene ID:
• Gene Symbol: PvMYB4a
• Gene Name: R2R3-MYB transcription factor4
• Genome:
• Species: Panicum virgatum

Functional Descriptions:

• Effects of overexpression of PvMYB4 in transgenic tobacco and switchgrass suggest that the gene is functionally orthologous to AtMYB4 and ZmMYB31.
• PvMYB4 binds directly to AC-I (preferred), AC-II and AC-III elements, both in vitro and in a yeast transcription system. Lignin biosynthetic genes are significantly down-regulated in PvMYB4-overexpressing plants, associated with reductions in lignin content and ester-linked p-CA:FA ratio.
• Overexpression of PvMYB4 in transgenic switchgrass increases saccharification efficiency threefold.
• 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.
