Cotton Fiber Development Time-course Analysis

Project description:To get glance to the events of the fast elongation and second cell wall synthesis stages of developing cotton fiber cells, we examined expression patterns of over 5000 genes by cDNA array from 3 to 18 DPA in a 3-day interval. RNAs from the 3-, 6-, 9-, 12-, 15-, and 18-DPA fibers were compared to the 9-DPA fiber RNA for time-course analysis. Four biological repeats were carried out including two dye-swap ones.

Cotton fiber LC-MS/MS - Proteomic Analysis of Differences in Fiber Development between Wild and Cultivated Gossypium hirsutum L

Project description:Upland cotton (Gossypium hirsutum L.) is one of the world’s most important fiber crops, accounting for more than 90% of all cotton production. While their wild progenitors have relatively short and coarse, often tan-colored fibers, modern cotton cultivars possess longer, finer, stronger, and whiter fiber. In this study, the wild and cultivated cottons (YU-3 and TM-1) selected show significant differences on fibers at 10 day post-anthesis (DPA), 20 DPA and mature stages at the physiological level. In order to explore the effects of domestication, reveal molecular mechanisms underlying these phenotypic differences and better inform our efforts to further enhance cotton fiber quality, an iTRAQ-facilitated proteomic methods were performed on developing fibers. There were 6990 proteins identified, among them 336 were defined as differentially expressed proteins (DEPs) between fibers of wild versus domesticated cotton. The down- or up-regulated proteins in wild cotton were involved in Phenylpropanoid biosynthesis, Zeatin biosynthesis, Fatty acid elongation and other processes. Association analysis between transcroptome and proteome showed positive correlations between transcripts and proteins at both 10 DPA and 20 DPA. The difference of proteomics had been verified at the mRNA level by qPCR, also at physiological and biochemical level by POD activity determination and ZA content estimation. This work corroborate the major pathways involved in cotton fiber development and demonstrate that POD activity and zeatin content have a great potential related to fiber elongation and thickening.

Activation of Arabidopsis seed hair development by cotton fiber-related genes

Project description:This experiment was designed to investigate the molecular basis of cotton fiber cell initiation. 32,000 ESTs were sequenced from Gossypium hirsutum L. TM-1 immature ovules (GH_TMO) and developed cotton oligonucleotide microarrays containing ~23,000 unigenes. Transcriptome analyses were performed to compare gene expression changes in laser capture microdissected fiber cell initials (or epidermis) and inner ovules. The gene expression profiles of the fiber cell initials were compared with those of the inner ovules in each developmental stage prior to, right at, and shortly after the initiation of fiber cells. Many genes in various molecular function or biological processes were over- or under-represented between fibers and non-fiber tissues in each developmental stage, suggesting temporal regulation of gene expression during early stages of fiber development. For gene expression studies using a large set cotton oligo-microarray, 4 developmental stages were chosen. To study differential expression during fiber initiation, ovules at -2 DPA, 0 DPA, and 2 DPA were used. One of the fiber elongation stage tissues (7 DPA) was included. In each developmental stage, epidermis was separated from inner ovules and subjected to the hybridization. In addition, epidermis and ovule comparisons were performed individually with 0 DPA as a control point for comparison.

non-coding RNA sequencing of upland cotton fiber and ovule

Project description:Three samples of cotton fiber harvested 3, 7 and 15 days post anthesis (DPA) and a sample of cotton ovule harvestd 0 DPA were used for non-coding RNA extraction and seloxa sequencing experiments, respectively.Cotton plants (Gossypium hirsutum cv. Xuzhou 142) were grown in a soil mixture in fully automated walk-in growth rooms with 300 M-BM-5mol mM-bM-^@M-^S2 sM-bM-^@M-^S1 average light intensity, 60% relative humidity and temperatures set to 30C during the light period and 28C during the dark (12-h light/dark cycle). These conditions were consistent throughout the year. Small RNA molecules under 30 bases were amplified and isolated from an agarose gel. The purified DNA was used directly for cluster generation and sequencing analysis using the Illumina Genome Analyzer IIx according to the manufacturer's instructions. The 38nt sequence tags from sequencing went through data cleaning first, which included getting rid of the low-quality tags and clipping adapter sequences. Three samples of cotton fiber harvested 3, 7 and 15 days post anthesis (DPA) and a sample of cotton ovule harvestd 0 DPA were used for non-coding RNA extraction and seloxa sequencing experiments, respectively.

Comparison of upland li mutant with normal fibers

Project description:The G. hirsutum mutant li1 is caused by a dominant mutation which has pleiotropic effects on plant development. To get information for molecular effects by li1 mutation on cotton fiber development, we examined expression patterns of over 5000 genes by cDNA array from 6 to 18 DPA in a 3-day interval between li1 mutant and normal fibers. Keywords: Mutant and normal fiber comparison

Identification and comparison of miRNAs involved in cotton fiber elongation between sea-island and upland cotton

Project description:To identify potential miRNAs involved in fiber development and elucidate their expression differences between G. barbadense and G. hirsutum, we constructed two small RNA libraries, Gb10 and Gh10, prepared from fibers of 3-79 (G. barbadense) and TM-1 (G. hirsutum) collected at 10 days post-anthesis (DPA). We identified 28 conserved miRNA families, including 24 that exactly match known plant miRNA families in miRBase. With MIREAP and newly developed software miRsearcher, 7 candidate-novel miRNAs were found. 5 candidate-novel miRNAs were expressed in both species, 2 candidate-novel miRNAs were expressed only in one species. Moreover, 4 miRNA families showed significant expression differences between sea-island cotton and upland cotton in 10 DPA fibers. two examples including 3-79 and TM-1 10 DPA fibers
