Transgenic tobacco plants expressing TrCel5A. Eight-week-old N. tabacum SR1 wt plants were grown in soil under standard conditions. Twenty plants of each line and wt were monitored on their stem size TrCel5A_AP plants showed a significant reduction in size and growth rate, whereas TrCel5A_ER plants were not significantly different from wt (D). The leaf shape of several transgenic plants was altered compared to wt (C). TrCel5A_ER (A) and TrCel5A_AP plants (B) displayed a curly leaf phenotype which in the case of TrCel5A_AP plants included additional necrotic lesions.
