Expression analysis of leafy spurge crown buds during seasonal dormancy transitions.

ABSTRACT: This submission contains the RNAseq data from a study of leafy spurge crown buds transitioning through a seasonal dormancy time course where buds transitioned from paradoprmancy to endodormancy and then to ecodormancy. The sequences in this study were mapped to an assembled transcriptome built from sequences from this study along with sequences from : 1) A study of leafy spurge crown buds through a time course for paradormancy release induced by excision of the aerial portion of the shoot (Series GSE71317). 2) A study identical to this study but where leafy spurge plants were first treated with glyphosate (Series GSE71406). 3) A previously submitted study of leafy spurge shoots following treatment with glyphosate was also used to assemble the transcriptome (Series GSE56509).

Expression analysis of leafy spurge crown buds during seasonal dormancy transitions after glyphosate treatments.

Project description:This submission contains the RNAseq data from a study of leafy spurge crown buds transitioning through a seasonal dormancy time course following glyphosate treatments where buds transitioned from paradoprmancy to endodormancy and then to ecodormancy. The sequences in this study were mapped to an assembled transcriptome built from sequences from this study along with sequences from : 1) A study of leafy spurge crown buds through a time course for paradormancy release induced by excision of the aerial portion of the shoot (Series GSE71317). 2) A study identical to this study but where leafy spurge plants were not treated with glyphosate (Series GSE71321). 3) A previously submitted study of leafy spurge shoots following treament with glyphosate was also used to assemble the transcriptome (Series GSE56509).

Expression analysis of leafy spurge crown buds during dormancy transitions and release.

Project description:This submission contains the RNAseq data from one (just the study on paradormancy release) of several studies used to assemble the leafy spurge tranacriptome. These assembled transcrptome was built from 1) A study of leafy spurge crown buds through a time course for paradormancy release induced by excision of the aerial portion of the shoot (this study). 2) A study of leafy spurge crown buds through a seasonal dormancy time course where buds transitioned from paradoprmancy to endodormancy and then to ecodormancy (Series GSE71321). 3) A study identical to #2 above but where leafy spurge plants were first treated with glyphosate (Series GSE71406). 4) A previously submitted study (Series GSE56509) of leafy spurge shoots following treament with glyphosate was also used to assemble the transcriptome.

This crown buds transitioning through a seasonal dormancy time course study has 4 biological replicates collected at each of the three dormancy states (paradormant, endodormant, and ecodormant).

Seasonal bud dormancy progression

Project description:This study investigated changes in the transcriptome of outdoor grown leafy spurge crown buds as they progress from paradormancy in August and September into endo dormancy in October through to ecodormancy in November and December. Keywords: Dormancy leafy spurge adventitious-buds A series of balanced dyeswap rolling circle hybiridizations were used with each year representing s seperate circle and with direction of the circles reversing on alternate years. Note, the Aug-Sep 04 hybridization failed and is missing from the dataset

Seasonal variation in leafy spurge crown bud gene expression

Project description:These experiments were designed to follow the seasonal changes in the transcriptome of field-grown leafy spurge crown buds. The goal was to identify specific signaling pathways and marker genes characteristic to the changes that occur when the buds transitioned from paradormancy through endodormancy and into ecodormancy. Keywords: Time course seasonal dormancy

Hormone and transcriptome profiling in aerial tissues derived from crown buds of glyphosate treated leafy spurge

Project description:Glyphosate is known to inhibit 5-enolpyruvylshikimate-3-phosphate synthase of the chorismate biosynthetic pathway, and chorismate is a precursor to aromatic amino acids, auxin, and many other secondary products. Although the perennial weed leafy spurge (Euphorbia esula L.) is considered glyphosate tolerant, glyphosate is often used as part of an integrated pest management program in non-cultivated ecosystems of North America. Part of its tolerance is attributed to escape through an abundance of underground adventitious buds (UABs). Sub-lethal concentrations of foliar applied glyphosate leads to new shoot growth from UABs that have a stunted and/or bushy phenotype after growth-inducing decapitation. To gain insights into glyphosateM-bM-^@M-^Ys impact on molecular mechanisms associated with the stunted and bushy phenotype, we obtained global transcriptome abundance using RNAseq from a subsequent generation of aerial shoots derived from crown buds of glyphosate-treated and -untreated leafy spurge. We further correlated transcript abundance to accumulation of shikimate and phytohormones from the same samples to elucidate interactions. Abundance of shikimate was similar in subsequent generations of aerial shoots generated from crown buds of treated and untreated plants and is likely not a direct factor leading to the stunted and bushy phenotype. However, the results do suggest that transcripts involved in auxin transport and signaling and crosstalk with other phytohormones likely play a role in the bushy phenotype. The results of this study provide some insights for identifying new targets for manipulation of plant growth and development. Transcriptome and metabolite profiling are obtained for aerial tissues derived from crown buds of foliar glyphosate-treated and control (2.24 or 0 kg/ha active ingredient glyphosate + 0.25% v/v surfactant) leafy spurge plants. Each experiment included 4 biological replicates.
