“…However, fewer studies have been carried out in cotton species. Hutchinson and Ghose [ 4 ] found a crinkled dwarf in upland cotton, which showed a normal phenotype during the seedling stage and a crinkled dwarf phenotype at the fourth- or fifth-leaf stage. Genetic analysis showed the mutant to be controlled by a completely recessive gene.…”

BackgroundDwarf cottons are more resistant to damage from wind and rain and associated with stable, increased yields, and also desirable source for breeding the machine harvest varieties. In an effort to uncover the transcripts and miRNA networks involved in plant height, the transcriptome and small RNA sequencing were performed based on dwarf mutant Ari1327 (A1), tall-culm mutant Ari3697 (A3) and wild type Ari971 (A9) in Gossypium hirsutum.MethodsThe stem apexes of wild-type upland cotton (Ari971) and its dwarf mutant (Ari1327) and tall-culm mutant (Ari3697) at the fifth true leaf stage were extracted for RNA, respectively. Transcriptome and small RNA libraries were constructed and subjected to next generation sequencing.ResultsThe transcriptome sequencing analysis showed that the enriched pathways of top 3 differentially expressed genes (DEGs) were categorized as carotenoid biosynthesis, plant-pathogen interaction and plant hormone signal transduction in both A1–A9 and A3–A9. The ABA and IAA related factors were differentially expressed in the mutants. Importantly, we found the lower expressed SAUR and elevated expressed GH3, and ABA related genes such as NCED and PP2C maybe relate to reduced growth of the plant height in Ari1327 which was consistent with the higher auxin and ABA content in this mutant. Furthermore, miRNA160 targeted to the auxin response factor (ARF) and miRNA166 (gma-miR166u and gma-miR166h-3p) targeted to ABA responsive element binding factor were related to the mutation in cotton. We have noticed that the cell growth related factors (smg7 targeted by gra-miR482 and 6 novel miRNAs and pectate-lyases targeted by osa-miR159f), the redox reactions related factors (Cytochrome P450 targeted by miR172) and MYB genes targeted by miR828, miR858 and miR159 were also involved in plant height of the cotton mutants. A total of 226 conserved miRNAs representing 32 known miRNA families were obtained, and 38 novel miRNAs corresponding to 23 unique RNA sequences were identified. Total 531 targets for 211 conserved miRNAs were obtained. Using PAREsnip, 27 and 29 miRNA/target conserved interactions were validated in A1–A9 and A3–A9, respectively. Furthermore, miRNA160, miRNA858 and miRNA172 were validated to be up-regulated in A1–A9 but down-regulated in A3–A9, whereas miRNA159 showed the opposite regulation.ConclusionsThis comprehensive interaction of the transcriptome and miRNA at tall-culm and dwarf mutant led to the discovery of regulatory mechanisms in plant height. It also provides the basis for in depth analyses of dwarf mutant genes for further breeding of dwarf cotton.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-015-2071-6) contains supplementary material, which is available to authorized users.

“…In cotton, the dwarf trait of most dwarf mutants of G. hirsutum L. and G. barbadense L. is described as being controlled by recessive genes. Earlier studies (Harland 1918; Hutchinson and Ghose 1937; Xu‐sheng et al. 2007) have shown that the dwarf traits are controlled by a pair of completely recessive genes.…”

“…We also found that leaves of AS98 were smaller than those of LHF10W99 although the shape of the leaves was normal and similar in both. However, all the dwarf mutants in cotton reported so far displayed crinkled leaves (Harland 1918, Hutchinson and Ghose 1937, McMichael 1942, Jian-xin et al 1996Xu-sheng et al 2007). The normally shaped leaves of the super-dwarf AS98 also support the conclusion that the dwarfness is mainly due to shorter internodes.…”

Morphological characters, inheritance and response to exogenous hormones of a cotton super‐dwarf mutant of Gossypium hirsutum

A novel super-dwarf mutant, named AS98, was discovered from an interspecific hybrid in 1998. Compared to the normal line LHF10W99, plant height and internode length were significantly shorter in AS98, but it had only slightly (3-5%) fewer internodes. Therefore, the shorter plant height was the result of shorter internodal length. AS98 was crossed with LHF10W99, and the F 1 , F 2 , BC 1 , and BC 2 populations were used for genetic analysis of the dwarf trait. The results showed that the trait was controlled by a single incomplete-dominant gene. Exogenous application of gibberellin acid (GA 3 ), brassinosteroid and indol acetic acid showed a significant response to GA 3 , which could restore plant height in AS98. The results thus provide a basis for utilizing the dwarf trait in breeding and studying the biosynthesis of GA or signal transduction in cotton.

Background Upland Cotton (Gossypium hirsutum L.) has few cotton varieties suitable for mechanical harvesting. The plant height of the cultivar is one of the key features that need to modify. Hence, this study was planned to locate the QTL for plant height in a 60Co γ treated upland cotton semi-dwarf mutant Ari1327. Results Interestingly, bulk segregant analysis (BSA) and genotyping by sequencing (GBS) methods exhibited that candidate QTL was co-located in the region of 5.80–9.66 Mb at D01 chromosome in two F2 populations. Using three InDel markers to genotype a population of 1241 individuals confirmed that the offspring’s phenotype is consistent with the genotype. Comparative analysis of RNA-seq between the mutant and wild variety exhibited that Gh_D01G0592 was identified as the source of dwarfness from 200 genes. In addition, it was also revealed that the appropriate use of partial separation markers in QTL mapping can escalate linkage information. Conclusions Overwhelmingly, the results will provide the basis to reveal the function of candidate genes and the utilization of excellent dwarf genetic resources in the future.
