Supplementary Fig 1 Semi-quantitative Reverse Transcriptase-PCR analysis showing AtNPR1 transcript accumulation in T 2 and T 3 generations of transgenic cotton.
Supplementary Fig 2 (a) Southern blot analysis on genomic DNA from transgenic cotton lines expressing AtNPR1. DNA was digested with EcoR1 and probed with P 32 labeled fragment of the AtNPR1 gene. (b) Map of AtNPR1 gene construct that was used to generate transgenic cotton. b a
** * * a b Supplementary Fig 3 Salicylic acid (SA)-induced (a) Chitinase and (b) Glucanase activities in the cotyledons of transgenic cotton line, 68L-19 following treatment of the roots with 3 mM SA. Roots of two-day old pre-germinated seedlings were treated with 3 mM SA and the cotyledons were harvested at different time points for enzyme activity analyses. Data represent mean±SE (n=10); the induced enzyme activity value for the transgenic line is significantly higher than that of the WT value at *P<0.05; **P<0.01.

Data represent mean ±SE (n=10); the induced enzyme activity values for the transgenic line is significantly higher than that of the WT value at ***P<0.001. a b

Non-transgenic Coker 312 plants (WT) were used as control and a Fusarium wilt-resistant, commercial cotton variety (DP 444) was used for comparison. Two parameters were used to score the effects of infection, three weeks following the inoculation of roots; (a) Shoot weight, and (b) Leaf disease index. Data represent mean ±SE, *P<0.05, n=12. (c) Photographs of various sets of plants showing their relative state before scoring for disease severity.

(a) Nematode count in soil after 10 weeks of inoculation, (b) Number of bolls per plant, (c) Boll weight per plant, (d) Boll position (Number of bolls at given nodes in 10 plants). Data represent mean ±SE, *P<0.05; **P<0.01, n=10. Note that on the 5 th day after inoculation, due to the equipment break down, the temperature in the growth chamber rose to 42 o C for several hours and the plants were transferred to and maintained in a greenhouse for four days before returning to the chamber for growth under controlled conditions until completion of the experiment. Also, note that the final nematode count in this experiment is substantially higher compared to what is presented for the experiment described in the main text. These high numbers are not unusual and have been reported previously for reniform nematodes (Agudelo et al. 2005). The large differences between two experiments can easily result from small variability in the number of reproductive cycles completed. Agudelo P, Robbins RT, Kim KS, Stewart MJ. 2005.
