Figure 4.

Heat map of the hormone response of the expression of LjPrx genes in roots. Plants grown in hydroponic cultures were treated for 48 h with 50 μm of each hormone. The effects of CK on LjPrx expression in leaves and nodules, and on LjCAT and LjAPXc genes, are also shown. Transcript levels were normalized with ubiquitin and expressed relative to those found in control plants, which were arbitrarily given a value of 1. Values are means ± se of four to 10 biological replicates from at least two independent treatments. ACC, 1-Aminocyclopropane-1-carboxylic acid; IAA, indole-3-acetic acid; SA, salicylic acid.
