• Rice OsPEX1, an extensin-like protein, affects lignin biosynthesis and plant growth., 2019, Plant Mol Biol.

Genbank accession number

• Rice leucine-rich repeat extensin-like protein OsPEX1 mediates the intersection of lignin deposition and plant growth
• When OsPEX1 was ectopically expressed in rice cultivars with tall stature that lacks the allele of semi-dwarf 1, well-known green revolution gene, the resulting transgenic plants displayed reduced height and enhanced lodging resistance
• Lastly, we demonstrated that modulating OsPEX1 expression could provide a tool for improving rice lodging resistance
• Conversely, OsPEX1-suppresssed transgenics displayed low lignin content and reduced transcriptional abundance of genes associated with lignin biosynthesis, indicating that the OsPEX1 mediates lignin biosynthesis and/or deposition in rice
• Our study uncovers a causative effect between the expression of OsPEX1 and lignin deposition
