The expression patterns of genes involved in sRNA biogenesis and action pathways in male and female reproductive structures of P. tabuliformis and A. thaliana. (a), The expression patterns of P. tabuliformis genes in male and female cones. Bars indicate the means and standard errors of three biological replicates. (b), The expression patterns of A. thaliana genes in the stamens and carpels. FS12 indicates flower stage 12. The expression data were downloaded from the A. thaliana database (http://jsp.weigelworld.org/expviz/expviz.jsp)
