Microarray of young shoot of Populus trichocarpa under abiotic stresses. Microarray of young shoot of Populus trichocarpa under abiotic stresses

We identified 1251 and 1509 significantly up-regulated and down-regulated genes, respectively (FDR<0.05) by drought-treatment. In contrast, in response to salt stress, only 133 genes and 309 genes were significantly up- and down-regulated (FDR<0.05) respectively. Of these, 55% of the up-regulated and 75% of the down-regulated genes were also identified in the drought data set. Overall design: To explore the mechanism by which poplar cell wall responses occur, we collected microarray data for young shoot (Ys) tissue in response to drought and salinity exposure
