The cab genes which encode the light-harvesting chlorophyll a/b-protein (LHCP) are expressed normally with respect to phytochrome regulation in the hy-3 and hy-5 long hypocotyl mutants of Arabidopsis thaliana. In etiolated seedlings of these mutants as well as of the wild type, 1 min of red light elevates cab mRNA levels substantially within 2 h; this increase is reversed if far-red light is given immediately after the red light treatment. We conclude that the genetic defects in these mutants do not affect steps in the signal transduction pathway leading to the regulated expression of cab genes. Additionally, the mRNA from one of the three known A. thaliana cab genes, AB140, is similar in quantity to the mRNAs from the other two, AB165 and AB180, in dark-grown seedlings of hy-3 and hy-5 as well as the parent A. thaliana (Landsberg) after a brief red light treatment. This aspect of cab gene expression differs from the strain Columbia of A. thaliana in which AB140 mRNA is the predominant message. In mature white light-grown plants of the strain Columbia, AB140 as well as a combination of AB165 and AB180 mRNAs are expressed at high levels, suggesting that AB165 and/or AB180 may be developmentally regulated.
