Drought stress is one of the most common environmental abiotic stress that affects the overall growth and development of plants. Comparative analysis was carried out between the transgenic plants (Gossypium hirsutum) inherited a gene related to small heat shock protein gene (sHSP) family (GHSP-26) and wild type (non-transgenic plants under different morphological, physiological and biochemical level. The GHSP-26 gene was isolated from the Gossypium arboreum which is one of the most tolerates species of cotton to different stress condition. In this study we also identified and analysed drought...
