Table 1. Plant growth in Arabidopsis expressing ISPS.
Leaf area, leaf curling, dry weights of leaf, stem, and aboveground plant organs, LMA, length of leaf, number of leaves, and inflorescence stem height were measured in 28- and 35-d-old Arabidopsis empty vector control (EV-B3) and lines expressing ISPS (B2 and C4). All plants were grown in growth chambers under a light intensity of 200 μmol m−2 s−1. Nd, Not determined. Different lowercase letters indicate significant differences between the three lines at P < 0.05 using one-way ANOVA followed by Fisher’s lsd test. Values represent means ± se (n = 5 plants per line).
