Sporobolus alterniflorus Transcriptome or Gene expression. Sporobolus alterniflorus

From the microarray experiment, many of the 43,311 probes were significantly different: 4,287 (9.9 %) between genotypes (WT and SaVHAc1-rice), 6,761 (15.6 %) between environments (saline or non-saline conditions), and 705 (1.6 %) responded differently to the environment depending upon the genotype. Although a large number of genes showed upregulation in SaVHAc1-rice relative to WT, eighteen genes that showed more than two-fold increase or decrease in transcription in SaVHAc1-rice were considered significantly up- or down-regulated, respectively. Fourteen genes encoding proteins with either ion transport or metal binding function were significantly upregulated. The four genes that showed significant down-regulation in SaVHAc1-rice did not have any functional annotation (hypothetical or expressed proteins). Interestingly, none of the other subunits of vATPase was observed as being affected by SaVHAc1. Overall design: Two genotypes (transgenic and wildtype), both exposed to two environments (saline and control) for up to 72 hours. Four biological replicates per genotype/environment combination. One sample per array.
