New Plant Invaders to Watch For Princess-tree (Paulownia tomentosa) The Threat: Princess-tree is a small to medium sized deciduous tree that can grow 30 to 60 feet tall. It has been planted as an ornamental but has been found to escape and colonize natural areas. Seeds are spread by wind and water. It’s ability to sprout from buds on stems and roots enhance its ability to survive, spread, and out-compete native plant species. Massachusetts is near the northern limit for winter hardiness of princess-tree and projected climate warming may allow this species to proliferate here. Large (up to 12 or more inches long) heart-shaped, broadly oval, or slightly lobed leaves are arranged in pairs along the stem. The underside of the leaves are hairy. Flowers are pale violet or whitish, tubular with five petals, and open in the Photo: James H. Miller, USDA Forest Service, spring.

www.nature.com/scientificreports OPEN Time-coursed transcriptome analysis identifes key expressional regulation in growth cessation and dormancy induced by short days in Paulownia Jiayuan Wang1, Hongyan Wang2, Tao Deng3, Zhen Liu1* & Xuewen Wang 3,4* Maintaining the viability of the apical shoot is critical for continued vertical growth in plants. Terminal shoot of tree species Paulownia cannot regrow in subsequent years. The short day (SD) treatment leads to apical growth cessation and dormancy. To understand the molecular basis of this, we further conducted global RNA-Seq based transcriptomic analysis in apical shoots to check regulation of gene expression. We obtained ~219 million paired-end 125-bp Illumina reads from fve time-courses and de novo assembled them to yield 49,054 unigenes. Compared with the untreated control, we identifed 1540 diferentially expressed genes (DEGs) which were found to involve in 116 metabolic pathways. Expression of 87% of DEGs exhibited switch-on or switch-of pattern, indicating key roles in growth cessation. Most DEGs were enriched in the biological process of gene ontology categories and at later treatment stages. The pathways of auxin and circadian network were most afected and the expression of associated DEGs was characterised. During SD induction, auxin genes IAA, ARF and SAURs were down-regulated and circadian genes including PIF3 and PRR5 were up-regulated. PEPC in photosynthesis was constitutively upregulated, suggesting a still high CO2 concentrating activity; however, the converting CO2 to G3P in the Calvin cycle is low, supported by reduced expression of GAPDH encoding the catalysing enzyme for this step. This indicates a de-coupling point in the carbon fxation.

The Effects of Wildland Fire and Other Disturbances on the Nonnative Tree Paulownia Tomentosa and Impacts on Native Vegetation
The Effects of Wildland Fire and Other Disturbances on the Nonnative Tree Paulownia tomentosa and Impacts on Native Vegetation THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Angela R. Chongpinitchai Graduate Program in Environment and Natural Resources The Ohio State University 2012 Master's Examination Committee: Roger Williams, Advisor Joanne Rebbeck David Hix Stephen Matthews Copyrighted by Angela Rose Chongpinitchai 2012 Abstract Increases in nonnative plant species to ecosystems of the United States have become a concern for the management of natural vegetation and ecological processes. Many exotic plant species are invasive, rapidly colonizing an area and spreading beyond the point of introduction. Nonindigenous plants can change the dynamics of soil properties, alter fire regimes, and interrupt ecological processes, such as nutrient and hydrologic cycles. These exotic plants often have a competitive edge over native species, due to adaptations in their native geographical range or because of a lack of natural predators in introduced habitats. Changes to microclimate conditions and direct competition from exotic plants often lead to a decrease in species richness in a habitat. Although this has been an issue for decades, little is known about many exotic plant species, particularly how they interact with natural vegetation in introduced habitats. Increased anthropogenic activity, such as logging, road construction, and prescribed burns, tends to facilitate invasions of exotic species by creating disturbed areas and reducing biodiversity. Paulownia tomentosa, a tree native to China, was first introduced to the U.S. in the 1840s as an ornamental; in recent decades the species has expanded its range since escaping cultivation.

Environmental and Plant Biology Ecology and invasive potential of Paulownia tomentosa (Scrulariaceae) in a hardwood forest landscape. (174 pp.) Director of Dissertation: Brian C. McCarthy Introduction of non-native species is the oldest form of human-induced global change. From the exchange of agricultural crops and domestic animals, to the accidental introduction of weeds and microbes, non-native species have been incorporated into the floras and faunas of all continents and most oceanic islands. These organisms can have marked effects on ecosystems. I wanted to address the following facets of non-native species invasion: (1) What characteristics of ecosystems make them more susceptible to non-native species invasion? and (2) What characteristics of the invader allow invasion? To address these questions, I used a gradient of anthropogenic disturbance common in southeastern Ohio forests: intact secondary forest, forest edge, and aggrading clear cuts.

Paulownia Control Plan
Scientific Name: Paulownia tomentosa Common Name: Princess Tree Updated: 12/30/2015 A. Priority: B B. Description – Native to eastern Asia, Paulownia tomentosa has been widely planted for horticultural purposes in North America from Montreal to Florida and west to Missouri and Texas. This tree is moderately cold-hardy so it has spread principally in the Eastern and Southern portions of the United States. In North Carolina it poses a particular problem in the foothill and mountain regions. Paulownia tomentosa is capable of flowering within 8 to 10 years and a mature tree can produce millions of seeds. The seeds are small and winged, dispersing easily in the wind. This aggressive tree grows rapidly (up to 15 feet per year) in all types of disturbed habitats. Princess tree may reach a height of up to 50 feet. The bark of this tree is characteristically gray with shallow, shiny ribs. The leaves are large (5-10 inches long on mature trees), heart-shaped, and oppositely arranged along the branches. The edges of the leaves often have blunt “horns” on each side. Stump sprouts and young plants have extremely large leaves that can be up to 32 inches long. This tree flowers in April and May, usually before its leaves have fully emerged. The very, large, light purple flowers are distinctively sticky and hairy on the outside. These flowers are arranged in pyramidal clusters that are about 10 to 15 inches long. The fruits appear from April through June and the hulls persist in large brown clusters through the winter and into early spring.

Amber List: Potential Species
Invasive Species Ireland Invasive Species Ireland http://invasivespeciesireland.com Amber List: Potential Species The risk assessment has generated prioritised lists of established and potential invasive species for Ireland and Northern Ireland. These lists been used to inform the selection of species for the development of Invasive Species Action Plans for potential and established invasive species. The risk assessment has also allowed the development of 'amber list' species. These lists identify species that, in the right ecological conditions, may have an impact on the conservation goals of a site or impact on a water body achieving good/high ecological status under the Water Framework Directive. The species listed in the following table are those that could represent a significant impact on native species or habitats causing significant decline or loss; or species that could impact either/both Natura 2000 sites and the goals of the WFD. These species did not achieve a high risk rating overall. In some cases, this may be due to a lower risk of arriving in Ireland due to the fact that the species is not yet present in Britain while in other cases some of these species have been shown to impact on conservation goals elsewhere but it is possible that they will not establish in the wild. Please see the database for more information on the overall scoring of these species.

Paulownia Tomentosa, an Exotic Species in North America, Is Spreading in fi Re-Opened Landscapes of Southern Appalachia
Paulownia tomentosa, an exotic species in North America, is spreading in fi re-opened landscapes of southern Appalachia. Nature in a Name: Paulownia tomentosa—Exotic Tree, Native Problem Summary While awareness of fi re’s importance in dry Appalachian forests, and the application of fi re as a restoration tool have increased over the last two decades, so too has the post-fi re invasion of Paulownia tomentosa (Princess tree). For the last ten years, managers have witnessed Paulownia invasion grow following fi re events. To understand this better, the team studied fi ve life history transitions for the species: seed dispersal, seed germination, seed survival over time through incorporation in the seed bank, initial habitat requirements, and seedling persistence to maturity. Paulownia seeds were found to disperse over two miles from their source tree. Fires of greater severity promote conditions Paulownia favors—exposed soil free of organic litter, and openings in the canopy cover that allow ample light. Subsequent persistence by Paulownia is greatest in the drier and more exposed areas, such as ridges and steep slopes. Fire Science Brief Issue 116 July 2010 Page 1 www.fi rescience.gov Key Findings • Paulownia seeds were widely dispersed. Though the majority of these wind-dispersed seeds did not travel far from the parent tree, seedlings were frequently encountered two miles from the nearest mature (seed producing) tree. • Paulownia trees had the greatest presence and numbers on high benches, crests and high slopes—places that are drier and experience greater fi re intensity. • Canopy cover was the most signifi cant predictor of Paulownia invasion overall.

Reproductive Biology of Paulownia Elongata, A
REPRODUCTIVE BIOLOGY OF PAULOWNIA ELONGATA, A MULTIPURPOSE TREE Brajesh N Vaidya, Richa Bajaj, Nirmal Joshee Graduate Program in Biotechnology, Fort Valley State University, Fort Valley, GA 31030, USA Contact: Nirmal Joshee [email protected] ABSTRACT: Paulownia genus is a group of fast growing trees that grow well in the southern United States. Paulownia (Paulowniaceae) is a genus of deciduous hardwood trees from China used for agroforestry, biomass production, land reclamation, and animal waste remediation. Paulownia (Paulownia tomentosa), or kiri, was introduced into the US during the 1800s. It quickly became naturalized over much of the eastern states. Except for its A B C ornamental qualities, it was generally ignored as a non-native weed tree. However, since Japanese buyers have begun to buy US grown logs, Paulownia is now considered a premier timber species. Forestlands, an important source of cellulosic biofuels feedstock, are expected to play an important role in meeting the national biofuel target. Plants are improved continuously by using molecular or classical breeding tools and in both cases it is important to have a clear understanding of reproductive biology. Light, Fluorescent, and Scanning D E Electron Micrography was conducted to study pollination and subsequent steps. Variable Figure 2. Paulownia in pictures. A.
