Cloning and Functional Analysis of the Promoter of an Ascorbate Oxidase Gene from Gossypium hirsutum
Apoplastic ascorbate oxidase (AO) plays significant roles in plant cell growth. However, the mechanism of underlying the transcriptional regulation of AO in Gossypium hirsutum remains unclear. Here, we obtained a 1,920-bp promoter sequence from the Gossypium hirsutum ascorbate oxidase (GhAO1) gene, and this GhAO1 promoter included a number of known cis-elements. Promoter activity analysis in ov...
Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton (Gossypium hirsutum) seed lots. There was no correlation, however, between its incidence and seedling emergence and disease symptoms on the emerged seedlings in autoclaved sand. Inoculation technique simulating internally seedborne nature of the fungus showed that the observed non-correla...
The SWEET (sugars will eventually be exported transporters) proteins are sugar efflux transporters containing the MtN3_saliva domain, which affects plant development as well as responses to biotic and abiotic stresses. These proteins have not been functionally characterized in the tetraploid cotton, Gossypium hirsutum, which is a widely cultivated cotton species. In this study, we comprehensive...
Acetyl-CoA carboxylase is an important enzyme, which catalyzes acetyl-CoA's carboxylation to produce malonyl-CoA and to serve as a committed step for de novo fatty acid biosynthesis in plastids. In this study, 24 putative cotton BCCP genes were identified based on the lately published genome data in Gossypium. Among them, 4, 4, 8, and 8 BCCP homologs were identified in Gossypium raimondii, G. a...
در این تحقیق امکان استفاده از ساقه پنبه (gossypium hirsutum l) در ساخت تخته خرده-چوب در دو مرحله مجزا مورد بررسی قرار گرفت. در مرحله اول ذرات پنبه به صورت مخلوط با خرده-چوب های صنوبر (populus nigra) برای ساخت تخته خرده چوب سه لایه مورد استفاده قرار گرفت.
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...
Membrane-bound fatty acid desaturases (FADs) are of great importance and play multiple roles in plant growth and development. In the present study, 39 full-length FAD genes, based on database searches, were identified in tetraploid upland cotton (Gossypium hirsutum L.) and were phylogenetically clustered into four subfamilies. Genomic localization revealed that 34 genes were mapped on 22 chromo...
ILD Gossypium anomalum Wawrs. and Peyr. among Gossypium species whas anomalous petal spot inheritance. Its petal spot involves two independently inherited genes; a ghost spot gene interacts with a spotless gene making a large anthocyanin area at the base of a petal (SILOW 1941). In the two cultivated Asiatic diploid species red petal spot involves three closely linked genesmargin. ghost spot, a...
A bacterial artificial chromosome library and BAC-end sequences for cultivated cotton (Gossypium hirsutum L.) have recently been developed. This report presents genome-wide single nucleotide polymorphism (SNP) mining utilizing resequencing data with BAC-end sequences as a reference by alignment of 12 G. hirsutum L. lines, one G. barbadense L. line, and one G. longicalyx Hutch and Lee line. A to...
گونههای جنس Gossypium (حدودا 42 گونه) ذخایر عظیمی از تنوع ژنتیکی برای اصلاح پنبه زراعی هستند. برای تعیین روابط ژنتیکی درون و بین گونهای جنس ,Gossypium 30 جفت آغازگر(Primer) ده تایی RAPD روی 13 رقم از دو گونه دیپلوئید زراعی( Gossypium herbaceum L. (A1) و Gossypium arboreum L. (A2) و 11 ژنوتیپ از دو گونه تتراپلوئید Gossypium hirsutum L. (AD) استفاده گردید. با استفاده از مارکر RAPD کلاً 422 ب...
