(Submitter supplied) New shoot growth from underground adventitious buds of leafy spurge is critical for survival of this invasive perennial weed after episodes of severe abiotic stress. Because global climate change is expected to increase abiotic stress, such as dehydration, objectives of this study include examining the impact that dehydration stress has on molecular mechanisms associated with vegetative reproduction. more...

(Submitter supplied) Leafy spurge is a model for studying well-defined phases of dormancy in underground adventitious buds (UABs) of herbaceous perennial weeds, which is a primary factor allowing many invasive perennial weeds to escape conventional control measures. A 12-week ramp down in both temperature (27°C → 10°C) and photoperiod (16 h → 8 h light) is required to induce a transition from para- to endo-dormancy in UABs of leafy spurge. more...

(Submitter supplied) Leafy spurge (Euphorbia esula) is an herbaceous perennial weed that produces vegetatively from an abundance of underground adventitious buds. The objectives of this study were to determine how mimicking natural seasonal conditions (photoperiod and temperature) under controlled environmental conditions affect dormancy and flowering competence; to determine molecular mechanisms associated with well-defined phases of seasonal dormancy transitions based on transcript profiles obtained by microarray analysis; and to link mechanisms regulating induction and release of endodormancy and flowering competence. more...

(Submitter supplied) 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. more...

(Submitter supplied) We investigated differential gene expression patterns in Populus vegetative buds between paradormant, endodormant, and ecodormant dormancy states. Our primary objectives were to (1) identify which individual genes, biological processes, molecular functions, and regulatory pathways were differentially expressed among dormancy states, (2) classify the differentially expressed genes into contrasting gene expression patterns, and (3) identify cis-acting elements associated with each gene expression group. more...

(Submitter supplied) Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. more...

Seedlings were incubated in 0.1% dimethyl sulfoxide (control) or 50 micromolar solutions of indole-3-acetic acid (IAA treatment) and benzyl aminopurine (BAP treatment) for 1h and 3h. Equal amounts of 1h and 3h samoles were pooled for each treatment before RNA isolation. more...

(Submitter supplied) Sporobolus stapfianus is a desiccation tolerant (DT) grass and a member of the Poaceae family alongside prominent crop and forage species. Despite the worldwide distribution of this family, most of its species are vulnerable to water loss within their vegetative tissues. As a DT species, S. stapfianus, could, therefore, serve as a model species for identifying the molecular changes that enabled such a rare occurrence of the DT phenotype in resurrection grasses and the implications of such a unique adaptation for agriculture. more...

(Submitter supplied) 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. more...

(Submitter supplied) By sequencing 36 cDNA libraries with Illumina technology, we identified genes differentially expressed in soybean plants in response to water deficit and genes that were either up- or down-regulated in different periods of the day. Of 54,175 predicted soybean genes (Glyma v1.1), 35.52% exhibited expression oscillations in a 24 h period. This number increased to 39.23% when plants were submitted to water deficit. more...

(Submitter supplied) Pre-exposure of plants to various abiotic conditions confers improved tolerance to subsequent stress. Mild drought acclimation induces acquired rapid desiccation tolerance (RDT) in the resurrection plant Boea hygrometrica, but the mechanisms underlying the priming and memory processes remain unclear. In this study, we demonstrated that drought acclimationinduced RDT can be maintained for at least four weeks but was completely erased after 18 weeks based on a combination of the phenotypic and physiological parameters. more...

(Submitter supplied) Arabidopsis thaliana plants that have experienced an initial exposure to dehydration stress (“trained plants”) have an increased ability to maintain leaf relative water content (RWC) during subsequent stresses than plants experiencing the stress for the first time and transcription of selected dehydration response genes is altered during successive exposures to dehydration stress. This physiological and transcriptional behavior of trained plants is consistent with a “memory “of an earlier stress. more...
