摘要：

Genes whose expression was up-regulated in low boron (B)-acclimated tobacco BY-2 (Nicotiana tabacum L. cv. Bright Yellow 2) cells, which had been selected under a low supply of B, were screened by the cDNA differential subtraction method. Thirteen genes were identified, including early salicylate-inducible glucosyltransferase, glutamine synthetase, glutathione S-transferase, and a pathogenesis-related protein, which might constitute a rescue system for oxidative damage. This indicates that B deficiency might impose cellular redox imbalance on the cells. Two of the 13 genes were induced within 30 min of B removal in the parent cells, indicating fast signal transfer from the cell walls to the cytoplasm.
