Transcription profiling of Arabidopsis wild type and SAL1 mutant plants grown under normal conditions

Null mutations in the SAL1 protein, a bi-functional protein with inositol polyphosphate-1-phosphotase activity and nucleosidase activity, result in mutants with altered leaf morphology, delayed growth and tolerance to drought stress. This experiment examines the gene expression of two SAL1 mutants, alx8 in the Col-0 background and fry1-1 in the C24 background, under normal growth conditions. In brief, RNA was extracted from the leaves of three plants of each mutant and their respective ecotypes two hours after lights on. Plants were grown under normal conditions for 5 weeks before harvesting. Each array represent a single biological replicate.
