英文摘要	Potassium (K+) deficiency as a common abiotic stress can inhibit the growth of plants and thus reduce the agricultural yields. Nevertheless, scarcely any development has been promoted in wheat transcriptional changes under K+ deficiency. Here we investigated root transcriptional changes in two wheat genotypes, namely, low-K+ tolerant "Tongzhou916" and low-K+ susceptible "Shiluano2-1". There were totally 2713 and 2485 probe sets displayed expression changes more than 1.5-fold in Tongzhou916 and Shiluano2-1, respectively. Low-K+ responsive genes mainly belonged to the categories as follows: metabolic process, cation binding, transferase activity, ion transporters and so forth. We made a comparison of gene expression differences between the two wheat genotypes. There were 1321 and 1177 up-regulated genes in Tongzhou916 and Shiluano2-1, respectively. This result indicated that more genes took part in acclimating to low-K+ stress in Tongzhou916. In addition, there were more genes associated with jasmonic acid, defense response and potassium transporter up-regulated in Tongzhou916. Moreover, totally 19 genes encoding vacuolar H+-pyrophosphatase, ethylene-related, auxin response, anatomical structure development and nutrient reservoir were uniquely up-regulated in Tongzhou916. For their important role in root architecture, K+ uptake and nutrient storage, unique genes above may make a great contribution to the strong low-K+ tolerance in Tongzhou916.
