Overuse of a small number of Upland cotton cultivars has narrowed cotton's genetic base, leading to major difficulties in developing cotton cultivars with diverse genetic backgrounds that are able to adapt to adverse conditions. To effectively broaden the genetic base, chromosome introgression lines (ILs) were developed, where TM‐1, the genetic standard of Upland cotton, was used as the common recipient and its two feral landraces, TX‐256 and TX‐1046, were used as the donors. A total of 115 ILs, with an average segment length of 11.15 cM, were first developed via intraspecific hybridization by marker‐assisted selection (MAS) in BC3F2 generations, spanning 3887.75 cM of the cotton genome. Association analysis showed that 63 markers were found to be associated with boll weight (BW), lint percentage (LP) and seed index. The percent of phenotypic variance explained by 148 QTLs detected was 4.12% on average. Eleven and five new QTLs for BW and LP (one stable QTL identified for LP in all environments) were detected, respectively, which can be used for efficiently pyramiding favourable alleles into one cultivar by MAS.

“…[110][111][112] Changes in expression of these genes decrease intracellular Na + levels and abscisic acid (ABA) contents and increase intracellular K + levels and cytokinin expression. 110,113,114 Similar to the effects of NO in cotton, exogenous hydrogen sulfide production enhances salt tolerance by decreasing Na + content in wheat seedlings. 115,116 During salt acclimation in Arabidopsis thaliana, cell wall remodeling, ethylene biosynthesis, and signaling pathways play crucial roles.…”

Environmental stresses are ubiquitous and unavoidable to all living things. Organisms respond and adapt to stresses through defined regulatory mechanisms that drive changes in gene expression, organismal morphology, or physiology. Immune responses illustrate adaptation to bacterial and viral biotic stresses in animals. Dysregulation of the genotoxic stress response system is frequently associated with various types of human cancer. With respect to plants, especially halophytes, complicated systems have been developed to allow for plant growth in high salt environments. In addition, drought, waterlogging, and low temperatures represent other common plant stresses. In this review, we summarize representative examples of organismal response and adaptation to various stresses. We also discuss the molecular mechanisms underlying the above phenomena with a focus on the improvement of organismal tolerance to unfavorable environments.

“…To date, CottonGen has 988 mapped QTL representing 25 traits by using interspecific and intraspecific populations. Researchers have detected QTL associated with fiber properties from both intraspecific populations of G. hirsutum and interspecific crosses between G. hirsutum 9 G. barbadense, as well as their later generations (e.g., Shappley et al 1998;Jiang et al 1998;Yu et al 1998;Kohel et al 2001;Paterson et al 2003;Zhang et al 2003Zhang et al , 2005Zhang et al , 2012Shen et al 2005;Lacape et al 2005;Chee et al 2005;He et al 2006;Wang et al 2006Wang et al , 2013aYu et al 2013). The QTL obtained from interspecific populations accounted for 80 % of the fiber quality QTL.…”

Mapping QTL for cotton fiber quality traits using simple sequence repeat markers, conserved intron-scanning primers, and transcript-derived fragments

Cotton is an important fiber crop worldwide. Improved fiber quality is a driving force for cotton genetic studies and breeding. A BC 1 population containing 115 individuals from a cross between Gossypium hirsutum cv. CCRI8 and G. barbadense cv. Pima 90-53 was established, and 519 simple sequence repeat (SSR) markers, two conserved intronscanning primers (CISPs), and transcript-derived fragments (TDFs) amplified from 156 ApoI/TaqI selective primer combinations were used to construct a genetic linkage map. The map included 579 markers distributed on 56 linkage groups. Accounting for 83.4 % of the cotton genome, it covered 4,168.72 cM, with an average distance of 7.19 cM between markers. Lengths of the linkage groups ranged from 1.25 to 255.79 cM, with 2 to 44 markers per group. Of these 56 groups, 43 were assigned to 26 chromosomes, with the remaining 13 unknown. Based on this newly constructed map of tetraploid cotton, we performed quantitative trait loci (QTL) mapping and analysis of fiber quality traits from the BC 1 and its derived BC 1 F 2 lines. A total of 44 fiber quality QTL were detected on 17 chromosomes, explaining 7.72-23.73 % of the phenotypic variation. Pima 90-53 offered 13 QTL alleles with positive additive effects and four with negative additive effects for fiber quality traits. The results from this study may provide useful information for breeders to transfer desirable fiber traits from cotton types, such as the Sea Island strain, to Upland cotton that is primarily cultivated currently.
