Abstract

Cotton Gossypium spp is an important fiber and oil crop High soil salinity affects cotton growth and production severely To identify genes in response to salt stress and clarify salt tolerance mechanism in cotton suppression subtractive hybridization SSH libraries were constructed from cotton roots under salt stress A total of 1131 expressed sequence tags ESTs from both forward and reverse libraries were assembled into 468 uniESTs and grouped into 11 functional categories according to Gene Ontology prediction The results showed that many physiological processes of cotton were influenced by salt stress Some signaling elements and transcription factors which might play important roles in salt stress response were carefully discussed The expression patterns of 21 selected genes under salt stress were validated by parallel method semiquantitative reverse transcriptasepolymerase chain reaction semiquantitative RTPCR which were consistent with SSH results An interaction network of saltresponsive genes was constructed and three molecular regulatory pathways of cotton were deduced Our findings might result in further understanding of salt stress response in cotton and contribute to genetically modified cotton with enhanced salt toleranceWe thank Dr Yi Huang from the Plant Biotechnology Institute National Research Council Canada for suggestions and revision on the manuscript and Dr Kunbo Wang from the Cotton Research Institute Chinese Academy of Agricultural Sciences for providing us seeds of “Zhong G5” We are also grateful to Ms Xiaoyan Guo for assistance on sequence blast analysis This study was supported by China National “863” Project to J Hua 2006AA10A108 Program for New Century Excellent Talents in University to J Hua NCET060106 and in part by grants from Changjiang Scholars and Innovative Research Team in University Programme of Introducing Talents of Discipline to Universities 111203
