Project description:This study is a time course of growth induction (0, 12, 24, 48, and 72 hrs) following the breaking of paradormancy in underground buds of the perennial weed leafy spurge (Euphorbia esula). Keywords: Time course, growth induction, apical dominance, paradormancy, root buds, leafy spurge
Project description:Transcriptome changes were investigated for Euphorbia esula (leafy spurge) seeds with a focus on the effect of constant and diurnal fluctuating temperature on dormancy and germination. Leafy spurge seeds do not germinate when incubated for 21 days at 20°C constant temperatures, but nearly 30% germinate after 21 days under fluctuating temperatures 20:30°C (16:8 h). Incubation at 20°C for 21 followed by 20:30°C resulted in approximately 63% germination in about 10 days. A cDNA microarray representing approximately 22,000 unique sequences was used to profile transcriptome changes.
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.
Project description: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). 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).
