Table I.

Genes whose expression was altered 4 h after the withdrawal of P from the nutrient solution

Elements (P, K, or N) were withdrawn from the nutrient solutions supplied to 28-d-old Arabidopsis plants growing hydroponically. Gene expression profiles were determined in shoots 4 h after the withdrawal of P and 28 h after the withdrawal of K or N. Gene expression was calculated as the ratio of transcript abundance in shoots of plants starved of P, K, or N divided by transcript abundance in shoots of plants supplied with full nutrient solution.

Affymetrix probe set number. ^b Qualitative estimates of absolute gene expression, classified as low (L, Affymetrix signal values < 150), medium (M) and high (H, Affymetrix signal values > 800). ^c Treatments for which genes were differentially expressed 2.5-fold in two biological replicates. (+), Genes whose expression has increased; (-), Genes whose expression has decreased. ^d Genes whose expression responds to auxin (a); aluminum (Al); brassinosteroids (b); cold (c); cell-cycle regulated (cc); drought (d); gravity (g); high light (hl); heat shock (hs); low oxygen (lo); mechanical stimulus (ms); oxidative stress (o); ozone (Oz); phosphate stress (P); salinity (s); sulfur deficiency (sulf); touch (t); and wounding and/or pathogen attack (w); see text for references. ^e AGI numbers and brief descriptions of the transcript identified by BLAST searching and from the descriptions provided by Ghassemian et al. (2002). ^f Functional categories for genes were identified using the AGI number to search the MIPS database (http://mips.gsf.de/proj/thal/db/; 28/11/02), where no category had been experimentally determined the category with the highest probability score was used.
