Abstract


Background: The importance of cotton crop (Gossypium hirsutum) in textile industry is based on its fiber quality. A number of fiber-specific genes play important role in the development of cotton fiber. Previous studies have demonstrated the importance of genes that are responsible for metabolic functions and their involvement in cotton fiber development.

Methods: This study was focused at successful Agrobacterium mediated stable transformation of the fiber gene CpTIP1, isolated from the wild plant Calotropis procera, into cotton variety NIAB-846 for one generation. 

Results: Transformation efficiency was calculated to be 1.01% for the target gene. Different molecular techniques such as PCR were used for confirmation and Real-Time PCR was used to check the level of quantitative expression of fiber expansin gene in putative transgenic cotton plants. On the base of molecular analysis, results showed higher expression level of fiber gene (CpTIP1) in transgenic plants as compared to the control plants.

Conclusion: The results of this study support the idea of improved cotton fiber through genetic modification especially the cotton fiber strength.
