Identification of putative monolignol transporter gene homolog I in Oryza sativa

Lignin is present in plant’s cell wall constitutes which mainly function to provide vital structural support to the plant. The transportation of lignin precursors, monolignols, from the membrane to the cell wall, where they are oxidized and polymerized, is facilitated by ATP dependent transport proc...
