Fusarium wilt (FW), caused by the fungus Fusarium oxysporum f. There are various limiting factors that threaten cotton production ( Hillock, 1992). barbadense, which is grown in the Xinjiang Autonomous Region, a Northwest province. China ranks the third after the United States and India in production of the extra-long staple G. barbadense is only grown in limited production areas in about a dozen of countries including China, India, Uzbekistan, Tajikistan, Turkmenistan, Spain, Egypt, Israel, Sudan, Peru, and the United States 1. However, due to its low yield potentials and requirements for warm and dry weathers, G. barbadense (extra-long staple, Egyptian, Pima or Sea-Island cotton) is grown for high quality fibers with long, strong and fine parameters ( Zhang et al., 2014). hirsutum (Upland cotton) is a tetraploid cotton species and is grown in more than 80 countries, producing 97% of world cotton due to its high yield and wide adaptation. In addition, it is also an important source of feed, food and biofuel components ( Fang and Percy, 2015). A further analysis confirmed that the expression of GB_D03G0217 was suppressed, leading to increased disease severity in plants of the resistant parent with virus induced gene silencing (VIGS).Ĭotton ( Gossypium spp.) is the most important fiber crop for the textile industry in the world. Through a comparative analysis of gene expression and DNA sequence for predicted genes within the QTL region between the two parents and selected lines inoculated with FOV7, GB_D03G0217 encoding for a calmodulin (CaM)-like (CML) protein was identified as a candidate gene. Nine quantitative trait loci (QTLs) for FOV7 resistance were identified, including qFOV7-D03-1 on chromosome D03 in two tests. barbadense from a cross between susceptible Xinhai 14 and resistant 06-146 in eight tests and constructed a high-density genetic linkage map with resequencing-based 933,845 single-nucleotide polymorphism (SNP) markers covering a total genetic distance of 2483.17 cM. To understand the genetic basis of cotton resistance to FOV race 7 (FOV7), this study evaluated a recombinant inbred line (RIL) population of 110 lines of G. vasinfectum (FOV) is one of the most destructive diseases in cotton ( Gossypium spp.) production, and use of resistant cultivars is the most cost-effective method managing the disease. 2Department of Plant and Environmental Sciences, New Mexico State University, Las Cruces, NM, United Statesįusarium wilt caused by Fusarium oxysporum f.1Engineering Research Centre of Cotton, Ministry of Education/College of Agriculture, Xinjiang Agricultural University, Ürümqi, China.Wanli Han 1†, Jieyin Zhao 1†, Xiaojuan Deng 1, Aixing Gu 1, Duolu Li 1, Yuxiang Wang 1, Xiaoshuang Lu 1, Qianli Zu 1, Qin Chen 1, Quanjia Chen 1, Jinfa Zhang 2 and Yanying Qu 1*
