“…Out of those 33 QTLs, five were related to physiological traits, 11 to plant productivity and 17 to fiber quality. Recently the NILs had also been developed by shifting the QTLs for yield and other traits among G. barbadence and G. hirsutum (Levi et al, 2009). A large number of QTLs associated with drought tolerance has also been identified in rice (Lafitte et al, 2007).…”

Abiotic stresses are one of the major constraints to crop production and food security worldwide. The situation has aggravated due to the drastic and rapid changes in global climate. Heat and drought are undoubtedly the two most important stresses having huge impact on growth and productivity of the crops. It is very important to understand the physiological, biochemical, and ecological interventions related to these stresses for better management. A wide range of plant responses to these stresses could be generalized into morphological, physiological, and biochemical responses. Interestingly, this review provides a detailed account of plant responses to heat and drought stresses with special focus on highlighting the commonalities and differences. Crop growth and yields are negatively affected by sub-optimal water supply and abnormal temperatures due to physical damages, physiological disruptions, and biochemical changes. Both these stresses have multi-lateral impacts and therefore, complex in mechanistic action. A better understanding of plant responses to these stresses has pragmatic implication for remedies and management. A comprehensive account of conventional as well as modern approaches to deal with heat and drought stresses have also been presented here. A side-by-side critical discussion on salient responses and management strategies for these two important abiotic stresses provides a unique insight into the phenomena. A holistic approach taking into account the different management options to deal with heat and drought stress simultaneously could be a win-win approach in future.

“…F-177 and Gossypium hirsutum (GH) cv. Siv'on, have been characterised for their metabolic and mineral compositions and compared to their parental genotypes (Levi et al, 2011). Plants were field-grown under wellwatered and water-limited conditions and comparative analysis was performed between i) GB and GH genotypes ii) the two water regimes and iii) each NIL and its recipient parent.…”

“…On the basis of the previously reported improved drought tolerance of the NILs versus their recipient parents, the authors focused their attention on those metabolites whose amount increased under stress in one or more of the NILs. In particular, an increase in aspartic acid, citric acid, malic acid, threonic acid, alanine, glycerol and myo-inositol among metabolites as well as in potassium, magnesium and calcium among minerals was suggested to contribute to the ameliorated adaptation to drought of these NILs (Levi et al, 2011).…”

“…Over the last two decades, many QTLs related to target traits have been identified using QTL-mapping methods by constructing intraspecific segregating populations of G. hirsutum with different target traits, such as fiber quality traits [4–6], yield and its components [7], resistance traits [8–10], early maturation traits [2, 11, 12] and drought-related traits [13]. In a study of traits associated with early maturity in cotton, more than 70 related QTLs were detected by linkage mapping [2, 11, 12].…”

BackgroundEarly maturity is one of the most important and complex agronomic traits in upland cotton (Gossypium hirsutum L). To dissect the genetic architecture of this agronomically important trait, a population consisting of 355 upland cotton germplasm accessions was genotyped using the specific-locus amplified fragment sequencing (SLAF-seq) approach, of which a subset of 185 lines representative of the diversity among the accessions was phenotypically characterized for six early maturity traits in four environments. A genome-wide association study (GWAS) was conducted using the generalized linear model (GLM) and mixed linear model (MLM).ResultsA total of 81,675 SNPs in 355 upland cotton accessions were discovered using SLAF-seq and were subsequently used in GWAS. Thirteen significant associations between eight SNP loci and five early maturity traits were successfully identified using the GLM and MLM; two of the 13 associations were common between the models. By computing phenotypic effect values for the associations detected at each locus, 11 highly favorable SNP alleles were identified for five early maturity traits. Moreover, dosage pyramiding effects of the highly favorable SNP alleles and significant linear correlations between the numbers of highly favorable alleles and the phenotypic values of the target traits were identified. Most importantly, a major locus (rs13562854) on chromosome Dt3 and a potential candidate gene (CotAD_01947) for early maturity were detected.ConclusionsThis study identified highly favorable SNP alleles and candidate genes associated with early maturity traits in upland cotton. The results demonstrate that GWAS is a powerful tool for dissecting complex traits and identifying candidate genes. The highly favorable SNP alleles and candidate genes for early maturity traits identified in this study should be show high potential for improvement of early maturity in future cotton breeding programs.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-016-2875-z) contains supplementary material, which is available to authorized users.
