CDNA expression profiles of +7 DPA wild-type upland cotton (Gossypium hirsutum cv. Xuzhou142) ovules over the one-year cycle

ABSTRACT: A cDNA library from 0-10 day post anthesis cotton ovules was established to study genes expressed in cotton ovule during initiation and quickly elongation period. We randomly sequenced over 100,000 ESTs from this library and acquired a gene pool of more than 28,000 UniESTs. The cotton UniESTs were then PCR-amplified and printed onto microarray. This array is comprised of about 28000 high-quality cotton cDNAs (with average length>750bp) and external controls. To study the different growth potential of cotton fibers in a one-year cycle, we then hybridized the array with RNA samples derived from +7 DPA wild-type upland cotton fibers in four different seasons, respectively.

cDNA expression profiles of wild-type and fl-mutant upland cotton ovules during fiber initiation peroid

Project description:We constructed cDNA library from 0-10 day post anthesis cotton fibers when fiber cells begin to initiate and elongate throughout this peroid. We randomly sequenced over 95,000 ESTs from this library, and with request of upland cotton ESTs from other laboratories, we acquired a gene pool of more than 30,000 UniESTs. The cotton UniESTs were then PCR-amplified and printed onto microarray. This array is comprised of about 29,000 high-quality cotton cDNAs (each sequence length>400bp, average length > 600bp) and external controls. Keywords: repeat samples for transcriptome analysis

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.

Identification of candidate thermotolerance genes during early seedling stage in upland cotton (Gossypium hirsutum L.) revealed by comparative transcriptome analysis

Project description:High temperature (HT) stress is a major environmental stress that limits cotton growth, metabolism, and yield worldwide. The identification and characterization of thermotolerance is restricted by the plant growth environment and growth stage. In this study, four genotypes of upland cotton (Gossypium hirsutum L.) with known field thermotolerance were evaluated under normal and HTs at the seedlings stage in a growth cabinet with 11 physiological, biochemical, and phenotypic assays. Consistent with previous field observations, the thermotolerance could be identified by genotype differences at the seedling stage under HT in a growth cabinet. Comparative transcriptome analysis was performed on seedlings of two contrasting cotton genotypes after 4 and 8 hours of HT exposure. Gene ontology analysis combined with BLAST annotations revealed a large number of HT-induced differentially expressed genes (4,698) that either exhibited higher expression levels in the heat-tolerant genotype (Nan Dan Ba Di Da Hua) compared with the heat-sensitive genotype (Earlistaple 7), or were differentially expressed only in Nan Dan Ba Di Da Hua. These genes encoded mainly protein kinases, transcription factors, and heat shock proteins, which were considered to play key roles in thermotolerance in upland cotton. Two heat shock transcription factor genes (homologs of AtHsfA3, AtHsfC1) and AP2/EREBP family genes (homologs of AtERF20, AtERF026, AtERF053, and AtERF113) were identified as possible key regulators of thermotolerance in cotton. Some of the differentially expressed genes were validated by quantitative real-time PCR analysis. Our findings provide candidate genes that could be used to improve thermotolerance in cotton cultivars.
