| molecular cloning, differential expression, and functional characterization of a family of class i ubiquitin-conjugating enzyme (e2) genes in cotton (gossypium). | two cdnas and their corresponding genes (ghubc1 and ghubc2) encoding ubiquitin-conjugating enzymes (e2s) have been cloned and characterized from allotetraploid cotton gossypium hirsutum ((ad)(1) genome). three additional e2 genes (gaubc1, gtubc2, and grubc2) have also been identified from diploid cottons gossypium arboreum (a(2) genome), gossypium thurberi (d(1) genome), and gossypium raimondii (d(5) genome), respectively. the derived amino acid sequences of the five closely related cotton e2s a ... | 2003 | 12591614 |
| behavioral mechanisms underlie an ant-plant mutualism. | predators can reduce herbivory by consuming herbivores (a consumptive effect) and by altering herbivore behavior, life history, physiology or distribution (non-consumptive effects). the non-consumptive, or trait-mediated, effects of predators on prey may have important functions in the dynamics of communities. in a facultative ant-plant mutualism, we investigated whether these non-consumptive effects influenced the host plants of prey. here, predaceous ants (forelius pruinosus) consume and distu ... | 2003 | 12647103 |
| a selection mosaic in the facultative mutualism between ants and wild cotton. | in protection mutualisms, one mutualist defends its partner against a natural enemy in exchange for a reward, usually food or shelter. for both partners, the costs and benefits of these interactions often vary considerably in space because the outcome (positive, negative or neutral) depends on the local abundance of at least three species: the protector, the beneficiary of protection and the beneficiary's natural enemy. in gossypium thurberi (wild cotton), ants benefit nutritionally from the pla ... | 2004 | 15590599 |
| geographic variation in a facultative mutualism: consequences for local arthropod composition and diversity. | geographic variation in the outcome of interspecific interactions may influence not only the evolutionary trajectories of species but also the structure of local communities. we investigated this community consequence of geographic variation for a facultative mutualism between ants and wild cotton (gossypium thurberi). ants consume wild cotton extrafloral nectar and can protect plants from herbivores. we chose three sites that differed in interaction outcome, including a mutualism (ants provided ... | 2010 | 20198388 |
| proteomic identification of differentially expressed proteins in gossypium thurberi inoculated with cotton verticillium dahliae. | thurber's cotton (gossypium thurberi) is the wild relative of cultivated cotton. it is highly resistant to cotton verticillium wilt, a disease that significantly affects cotton yield and quality. to reveal the mechanism of disease resistance in g. thurberi and to clone resistance-related genes, we used two-dimensional electrophoresis (2-de) and tandem time-of-flight mass spectrometry (maldi-tof-ms) to identify differentially expressed proteins in thurber's cotton after inoculation with verticill ... | 2011 | 22325879 |
| comparative proteomic analysis of gossypium thurberi in response to verticillium dahliae inoculation. | verticillium wilt is threatening cotton productivity globally. this disease is caused by soil-borne verticillium dahliae which directly infects cotton roots, and exclusively colonizes and occludes xylem vessels, finally resulting in necrosis, defoliation, and most severely, plant death. for the first time, itraq (isobaric tags for relative and absolute quantification) was applied to screen the differentially expressed proteins of gossypium thurberi inoculated with v. dahliae. a total of 6533 pro ... | 2015 | 26506344 |
| individual chromosome assignment and chromosomal collinearity in gossypium thurberi, g. trilobum and d subgenome of g. barbadense revealed by bac-fish. | the experiment on individual chromosome assignments and chromosomal diversity was conducted using a multi-probe fluorescence in situ hybridization (fish) system in d subgenome of tetraploid gossypium barbadense (d(b)), g. thurberi (d(1)) and g. trilobum (d(8)), which the later two were the possible subgenome donors of tetraploid cottons. the fish probes contained a set of bacterial artificial chromosome (bac) clones specific to 13 individual chromosomes from d subgenome of g. hirsutum (d(h)), a ... | 2011 | 21952206 |

| gossypolhemiquinone, a dimeric sesquiterpenoid identified in cotton (gossypium). | the report that the cotton leaf perforator, bucculatrix thurberiella, is one of the few insect herbivores to attack gossypium thurberi prompted an investigation of the terpenoids present in the leaves of this wild species of cotton. members of gossypium produce subepidermal pigment glands in their leaves that contain the dimeric sesquiterpenoid gossypol as well as other biosynthetically related terpenoids. in addition to gossypol, a previously unknown dimeric sesquiterpenoid, gossypolhemiquinone ... | 2016 | 26725485 |
| trade-offs among anti-herbivore resistance traits: insights from gossypieae (malvaceae). | plant defense theories commonly predict negative correlations among anti-herbivore resistance traits. although this prediction has been widely accepted, the majority of empirical studies have failed to account for similarities among species due to common ancestry, thus risking pseudoreplication. wild cotton plants possess traits conferring both direct resistance (toxic leaf glands and trichomes) and indirect resistance (extrafloral nectaries that reward enemies of herbivores). the evidence for n ... | 2004 | 21653443 |
| induced resistance to herbivores and the information content of early season attack. | current models of induced plant defenses all assume that herbivory is predictable. present damage must provide information about the likelihood of future attack. we tested this assumption by measuring the relationship between damage early in the season and the number of subsequent attacks by cotton leaf perforators, bucculatrix thurberiella, to plants of wild cotton, gossypium thurberi, at three sites in the sonoran desert. damage early in the season was a good predictor of the number of new min ... | 1996 | 28307267 |
| analysis of repetitive dna in three species of gossypium. | the rate of reassociation of denatured dna was determined for two selected diploid species, gossypium thurberi (d genome) and g. arboreum (a genome), and one allotetraploid species, g. hirsutum (ad genome). the relative genome size and dna content of the chromosomes of the diploids were a greater than d. renaturation curves indicated that the differences in genome sizes were due primarily to the repetitive dna content. | 1976 | 1016222 |
