Figure 2

Expression of PtLIM genes using semi quantitative RT-PCR analysis in opposite and tension wood. Three young poplars (Populus tremula × P. alba) were cultivated in the greenhouse for two months, and tilted for one month to induce tension wood formation. Phloem and bark (PB), cambial zone (CZ), developing xylem (DX) and mature xylem (XM) samples were scraped from the upper side (tension wood) and the lower side (opposite wood) of tilted stems. 18S rRNA signals are indicative of the total RNA quantity in each sample
