Abstract

ABSTRACT Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance to stresses. Transcription factors (TFs) mostly are present in different copies or isoforms by which they conduct their regulation. Their copy number can determine organism behavior to a cue. Simple sequence repeats (SSRs) are one of the most informative and versatile molecular markers. Transcription factors of three Gossypium species were compared in silico. Seventy eight percent of TFs were common between the three species. Single copy for each species were 6057 TF. Gossypium hirsutum and G. raimondii shared the most common interspecific TF. Gossypium arboreum species-specific TF were the least. MYB TF family with its subfamilies is the most abundant followed by bHLH and AP2/ERF family. Gossypium hirsutum generally possesses more TF copies compared to other two species. The 2109 single-copy clusters indicate that G. hirsutum has received one copy from only one parent. The five most abundant SSR markers of TF were dinucleotides AT, TA, TC, CT and TG belonging to G. raimondii. For G. arboreum and G. hirsutum they were trinucleotides CAA, CGA, TGA, GAA (CAT: G. hirsutum) and TCA. The findings suggest that there is regulatory difference between the three Gossypium species for fiber production and insect attack response. The differences may be due to some adaptive deletion events during speciation of G. hirsutum from its parents G. arboreum and G. raimondii.

Highlights

  • Cotton plant belonging to Gossypium genus is one of the principal providers of cellulosic fiber and of great economic importance

  • The integrated Transcription factors (TFs) list of each species that was subject to group the TF families show that TFs, in terms of family number and member, were most in G. hirsutum followed by G. raimondii and G. arboreum, respectively

  • Gossypium hirsutum gains 61 TF families followed by G. raimondii with 60 and G. arboreum with 59 families (Table 2)

Summary

Introduction

Cotton plant belonging to Gossypium genus is one of the principal providers of cellulosic fiber and of great economic importance. It is one of the most important oleaginous crops worldwide because of cottonseed, which makes it an economically and agronomically important crop, mainly for the textile industry where it is usually utilized as raw material for the manufacture of garments. According to an estimated approximation concerning the world production of cotton, 80% of cotton fiber comes from Brazil, China, India, Pakistan, Turkey, USA and Uzbekistan. Breeding for stress-resistant cotton is a fundamental issue for plant biotechnology programs This importance makes it mandatory to advance the application of biotechnological tools for cotton improvement (Rathore et al 2015) in order to provide solutions to common problems that cotton producers are facing quotidianly
