Association Study and Mendelian Randomization Analysis Reveal Effects of the Genetic Interaction Between and on Wood Formation in .

MicroRNAs (miRNAs), important posttranscriptional regulators of gene expression, play a crucial role in plant growth and development. A single miRNA can regulate numerous target genes, making the determination of its function and interaction with targets challenging. We identified PtomiR403b target to , which encodes a galactosyltransferase responsible for the biosynthesis of cell wall polysaccharides.
