| suppression of cotton leaf curl disease symptoms in gossypium hirsutum through over expression of host-encoded mirnas. | cotton leaf curl disease (clcud), a major factor resulting in the enormous yield losses in cotton crop, is caused by a distinct monopartite begomovirus in association with cotton leaf curl multan betasatellite (clcumb). micro(mi)rnas are known to regulate gene expression in eukaryotes, including antiviral defense in plants. in a previous study, we had computationally identified a set of cotton mirnas, which were shown to have potential targets in the genomes of cotton leaf curl multan virus (clc ... | 2017 | 29017848 |
| ptxd gene in combination with phosphite serves as a highly effective selection system to generate transgenic cotton (gossypium hirsutum l.). | this report demonstrates the usefulness of ptxd/phosphite as a selection system that not only provides a highly efficient and simple means to generate transgenic cotton plants, but also helps address many of the concerns related to the use of antibiotic and herbicide resistance genes in the production of transgenic crops. two of the most popular dominant selectable marker systems for plant transformation are based on either antibiotic or herbicide resistance genes. due to concerns regarding thei ... | 2017 | 29032395 |
| the jasmonate zim-domain gene family mediates ja signaling and stress response in cotton. | jasmonate zim-domain (jaz) family proteins are involved in regulating diverse biological processes in plants. however, their functions have not been well characterized in cotton (gossypium spp.). in the present study, 13, 15, 25 and 30 jaz genes were identified in gossypium arboretum, gossypium raimondii, gossypium barbadense and gossypium hirsutum, respectively, based on gene homology. selection and variation analyses showed that the single nucleotide polymorphism (snp) density of ghjaz genes i ... | 2017 | 29036515 |
| the terpene synthase gene family in gossypium hirsutum harbors a linalool synthase ghtps12 implicated in direct defence responses against herbivores. | herbivore-induced terpenes have been reported to function as ecological signals in plant-insect interactions. here, we showed that insect-induced cotton volatile blends contained 16 terpenoid compounds with a relatively high level of linalool. the high diversity of terpene production is derived from a large terpene synthase (tps) gene family. the tps gene family of gossypium hirsutum and gossypium raimondii consist of 46 and 41 members, respectively. twelve tps genes (ghtps4-15) could be isolate ... | 2018 | 29044662 |
| interaction between calcium and potassium modulates elongation rate in cotton fiber cells. | calcium (ca2+) is necessary for fiber cell development in cotton (gossypium hirsutum), both as a cell wall structural component and for environmental signaling responses. it is also known that potassium (k+) plays a critical role in cotton fiber cell elongation. however, it is unclear whether ca2+ integrates its activities with k+ to regulate fiber elongation. here, we report the novel discovery that ca2+ deficiency, when integrated with k+ signaling, promotes fiber elongation. using inductively ... | 2017 | 29045717 |

| transcriptomics reveals multiple resistance mechanisms against cotton leaf curl disease in a naturally immune cotton species, gossypium arboreum. | cotton leaf curl disease (clcud), caused by cotton leaf curl viruses (clcuvs), is among the most devastating diseases in cotton. while the widely cultivated cotton species gossypium hirsutum is generally susceptible, the diploid species g. arboreum is a natural source for resistance against clcud. however, the influence of clcud on the g. arboreum transcriptome and the interaction of clcud with g. arboreum remains to be elucidated. here we have used an rna-seq based study to analyze differential ... | 2017 | 29162860 |
| larval dispersal of spodoptera frugiperda strains on bt cotton: a model for understanding resistance evolution and consequences for its management. | high dispersal of lepidoptera larvae between non-bt and bt cotton plants can favour the evolution of insect resistance; however, information on host acceptance of neonates in tropical transgenic crops is scarce. therefore, the purposes of this study were as follows: (i) to investigate the feeding behaviour of susceptible and cry1f-resistant strains of spodoptera frugiperda (j.e. smith) on bt and non-bt cotton (gossypium hirsutum l.) varieties and (ii) to understand the possible effects of cotton ... | 2017 | 29170392 |

| diaheliotropic leaf movement enhances leaf photosynthetic capacity and photosynthetic light and nitrogen use efficiency via optimising nitrogen partitioning among photosynthetic components in cotton (gossypium hirsutum l.). | phototropic leaf movement of plants is an effective mechanism for adapting to light conditions. light is the major driver of plant photosynthesis. leaf n is also an important limiting factor on leaf photosynthetic potential. cotton (gossypium hirsutum l.) exhibits diaheliotropic leaf movement. here, we compared the long-term photosynthetic acclimation of fixed leaves (restrained) and free leaves (allowed free movement) in cotton. the fixed leaves and free leaves were used for determination of pa ... | 2017 | 29222927 |
| laccase ghlac1 modulates broad-spectrum biotic stress tolerance via damp-triggered immunity. | plants are constantly challenged by a multitude of pathogens and pests, which causes massive yield and quality losses annually. a promising approach to reduce such losses is to enhance the immune system of plants through genetic engineering. previous work has shown that laccases (p-diphenol:dioxygen oxidoreductase, ec 1.10.3.2) function as lignin polymerization enzymes. here we demonstrate that transgenic manipulation of the expression of the laccase gene ghlac1 in cotton (gossypium hirsutum) ca ... | 2017 | 29229698 |
| long-term exposure to slightly elevated air temperature alleviates the negative impacts of short term waterlogging stress by altering nitrogen metabolism in cotton leaves. | short-term waterlogging and chronic elevated temperature occur frequently in the yangtze river valley, yet the effects of these co-occurring environments on nitrogen metabolism of the subtending leaf (a major source leaf for boll development) have received little attention. in this study, plants were exposed to two temperature regimes (31.6/26.5 °c and 34.1/29.0 °c) and waterlogging events (0 d, 3 d, 6 d) during flowering and boll development. the results showed that the effects of waterlogging ... | 2017 | 29253802 |

| genetic dissection of the fuzzless seed trait in gossypium barbadense. | cotton fibres are single-celled trichomes arising from the epidermal cells of the seed coat and may be either long (lint) or very short (fuzz). the dominant fuzzless n1 of gossypium hirsutum is a defective allele of the at-subgenome homoeolog of myb25-like, but the genetic components underlying the recessive fuzzless trait from g. barbadense (gb) are unknown. we have identified five genetic loci, including a major contributing locus containing myb25-like_dt, associated with gb fuzzless seeds bas ... | 2018 | 29351643 |
| a pectin methylesterase inhibitor enhances resistance to verticillium wilt. | pectins are major components of the primary plant cell wall, which functions as the primary barrier against pathogens. pectin methylesterases (pmes) catalyze the demethyl esterification of the homogalacturonan domains of pectin in the plant cell wall. their activity is regulated by pectin methylesterase inhibitors (pmeis). here, we provide evidence for the role of the pectin methylesterase-inhibiting protein ghpmei3 from gossypium hirsutum in plant responses to verticillium dahliae infection; gh ... | 2018 | 29363564 |
| genome-wide identification and comparative analysis of the 3-hydroxy-3-methylglutaryl coenzyme a reductase (hmgr) gene family in gossypium. | terpenes are the largest and most diverse class of secondary metabolites in plants and play a very important role in plant adaptation to environment. 3-hydroxy-3-methylglutaryl coenzyme a reductase (hmgr) is a rate-limiting enzyme in the process of terpene biosynthesis in the cytosol. previous study found the hmgr genes underwent gene expansion in gossypium raimondii, but the characteristics and evolution of the hmgr gene family in gossypium genus are unclear. in this study, genome-wide identifi ... | 2018 | 29364830 |
