Vascular cell expression patterns of Arabidopsis bZIP group I genes
The bZIP transcription factors are involved in various aspects of plant development. Studies of bZIP group I genes in several species have indicated that they may play a role in vascular development. In order to elucidate the functions of <i>Arabidopsis</i> bZIP group I genes in vascular development, the expression pattern of seven <i>AtbZIP</i> group I genes, <i>AtbZIP18</i>, <i>29</i>, <i>30</i>, <i>51</i>, <i>52</i>, <i>59</i>, and <i>69</i>, were examined in relation to vascular development using promoter::reporter lines of transgenic <i>Arabidopsis</i> plants. <i>AtbZIP18</i>, <i>51</i>, <i>52</i>, and <i>59</i> were preferentially expressed in developing vascular cells including differentiating vessels and their precursor cells. <i>AtbZIP18</i>, <i>52</i>, and <i>59</i> showed partially overlapping expression in vascular cells of cotyledons, and partially overlapping expression of <i>AtbZIP51</i>, <i>52</i>, and <i>59</i> was observed in root vascular cells. These results suggest that th ese genes may have partially redundant functions in vascular development.
