ROLE OF TRANSCRIPTION FACTORS IN IMPROVING THE COTTON FIBER DEVELOPMENT
Ammara Masood
Abstract
Cotton is the most essential fibre and oilseed crop in the world which is commonly known as the White Gold. Pakistan ranked at 4th among cotton producing countries in the world. It is considered as a life line of our country and has 0.8 percent share in GDP and contributes 4.5 percent in agriculture value addition. The present investigation was carried out to estimate the role of 5 different transcription factors (MYB, TCP, ERF, NAC & WRKY) in improving the quality of cotton and its fiber development. In which we concluded that the Myb plays a part in controlling the growth of fiber in cotton, chromosomal site determination,identification of conserved motifs, gene structure analysis, transcriptome (RNA Seq) analysis. The NAC transcription factor is involved in so many biotic processes like abiotic stress & pathogen attack response such as temperature, salinity, and drought, and also cell division, fetal development, leaf thrush. The plant TCP is involved in growth of cotton plants, such as branching, seed germination, circadian clock management, hormone pathways, development of gametophyte. WRKY play a role in both de-repression and repression on essential plant processes of cotton. ERF gene plays an essential role in the cotton stress response as well as in the management of various developmental processes.
