De novo characterization of alligator weed (Alternanthera philoxeroides) transcriptome shedding light on gene expression under potassium deprivation

We use solexa sequencing technology to analysis root transcriptome of alligator weed during 7 d potassium deficiency. Further analysis suggested that 9,253 differentially expressed genes (DEGs) were up-regulated and 2,138 DEGs were down-regulated after potassium deficiency for 7 days, including 121 transcription factors, 108 kinases, 146 transporters, and 178 genes that were related to stress. Our results afford a valuable resource for genetic and genomic research on plant potassium deficiency. Overall design: Examination of 2 different root samples (control and treatment)
