AB  - We performed the inoculation of transgenic cotton seedlings with <i>Trichoderma</i> sp. strain ICA 4 to evaluate its effects on the physiological development of seedlings. Inoculated seedlings of transgenic cotton had higher development than non-inoculated seedlings. The range of values for relative growth, doubling time, height and number of leaves (0.04 g/g d; 16.88 days; 17.16 cm and 4.2, respectively) were significantly higher that those observed in non-inoculated plants (0.03 g/g day; 24.38 days; 12.33 cm and 2.6, respectively). Regarding radical architecture, inoculated seedlings with <i>Trichoderma</i> strain ICA 4 showed a higher percentage of roots of 2<sup>nd</sup> (46%), 3<sup>rd</sup> (73%) and 4<sup>th</sup> (98%) order with respect to control plants. This indicates that inoculation of <i>Trichoderma strain</i> ICA 4 can promote better nutrient use. Future studies should be designed to evaluate the expression of genes involved in the biosynthesis of plant hormones that could be involved in root development.
