Visualizing Wood Anatomy in Three Dimensions with High-Resolution X-Ray Micro-Tomography (Μ CT) – a Review –
408 IAWAIAWA Journal Journal 34 (4), 34 2013: (4), 2013 408–424 VISUALIZING WOOD ANATOMY IN THREE DIMENSIONS with high-resolution X-ray micro-tomography (µ CT) – A REvIEW – Craig R. Brodersen Horticultural Sciences Department, Citrus Research & Education Center, University of Florida, 700 Experiment Station Road, Lake Alfred, FL 33850, U.S.A. E-mail: [email protected] ABsTracT High-resolution X-ray micro-tomography (μCT) has emerged as one of the most promising new tools available to wood anatomists to study the three-dimensional organization of xylem networks. This non-destructive method faithfully repro- duces the spatial relationships between the different cell types and allows the user to explore wood anatomy in new and innovative ways. With μCT imaging, the sample can be visualized in any plane and is not limited to a single section or exposed plane. Conventional CT software aids in the visualization of wood structures, and newly developed custom software can be used to rapidly automate the data extraction process, thereby accelerating the rate at which samples can be analyzed for research. In this review the origins of xylem reconstructions using traditional methods are discussed, as well as the current applications of μCT in plant biology and an overview of pertinent technical considerations associated with this technique. μCT imaging offers a new perspective on wood anatomy and highlights the importance of the relationships between wood structure and function. Keywords: Synchrotron, 3D, tomography, wood anatomy, visualization, μCT. INTrOducTiON Over the past 10–15 years high resolution X-ray micro-computed tomography (μCT) has seen a surge in popularity as a tool for producing three-dimensional (3D) visualiza- tions of plant tissue. -

The two data sets are congruent in that the genera Prunus s.l. and Maddenia form a monophyletic group, with Maddenia nested within Prunus. -
Latitudinal Gradient in Leaf Defense Traits of Woody Plants Along Japanese Archipelago
Latitudinal gradient in leaf defense traits of woody plants along Japanese archipelago 日本産樹木種における、葉防御形質の緯度傾度 Saihanna 1 General Introduction It is estimated that over the twenty million species of organisms are living on our planet, and all of these organisms adapted to their own living environment, namely niche (Hatchinson 1957). Not only the abiotic factors but biotic interaction plays a key role in the maintenance of biodiversity. Animal-plant interactions are one of the most important topic in community ecology (e.g. Morin 1999). Plants and herbivore insects have accounted for about half of the entire diversity on the earth (Strong et al., 1984). Plant-herbivore interactions are extremely complex, which should lead the tremendous diversity of both plants and herbivores (e.g. Gutierrez et al., 1984; Hay et al., 1989). Although the interaction between these two components, namely co-speciation, should account for this diversification, most of the studies so far, tend to explain this interaction only from one side of them. Plants have interacted with insect herbivores for several hundred million years, which should lead to complex defense systems against various herbivores (Fürstenberg-Hägg et al., 2013). This interaction between plants and herbivores has long proposed the opportunity for studying the mechanism of the creation and maintenance of biological diversity because of its universality and generality (Strong et al. 1984; Ali and Agrawal 2012). It is believed that the evolution of plant defense traits followed by counter-adaptations in herbivores could lead to bursts of adaptive radiation of both components (Ehrlich and Raven 1969). Understanding the coevolution of plant and insect species and macroevolution of adaptive traits has inspired biologists for some decades, yet has been challenging to study even present days (Schluter, 2000). -

OCCURRENCE OF CANKER AND WOOD ROT PATHOGENS ON STONE FRUIT PROPAGATION MATERIAL AND NURSERY STONE FRUIT TREES by RHONA VAN DER MERWE Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in the Faculty of AgriSciences at the University of Stellenbosch Supervisor: Prof L Mostert Co-supervisor: Prof F Halleen April 2019 Stellenbosch University https://scholar.sun.ac.za DECLARATION By submitting this thesis/dissertation electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: 14 February 2019 Sign: Rhona van der Merwe Copyright © 2019 Stellenbosch University All rights reserved II Stellenbosch University https://scholar.sun.ac.za SUMMARY The phytosanitary status of stone fruit propagation material and nursery trees in South Africa are not known. Canker and wood rot pathogens can be present in visibly clean material. Due to stress and other improper cultural practices, symptoms will be expressed and cankers, dieback of parts of the tree and possible death of the trees can be seen. Therefore, the aim of this study was to identify the fungal canker and wood rot pathogens present in propagation material and nursery stone fruit trees. Green scion shoots were collected from three plum and one nectarine cultivars and dormant scion shoots were collected from three plum cultivars. -

Plants of the Seattle Japanese Garden 2020
PLANTS OF THE SEATTLE JAPANESE GARDEN 2020 Acknowledgments The SJG Plant Committee would like to thank our Seattle Parks and Recreation (SPR) gardeners and the Niwashi volunteers for their dedication to this garden. Senior gardener Peter Putnicki displays exceptional leadership and vision, and is fully engaged in garden maintenance as well as in shaping the garden’s evolution. Gardeners Miriam Preus, Andrea Gillespie and Peter worked throughout the winter and spring to ensure that the garden would be ready when the Covid19 restrictions permitted it to re-open. Like all gardens, the Seattle Japanese Garden is a challenging work in progress, as plants continue to grow and age and need extensive maintenance, or removal & replacement. This past winter, Pete introduced several new plants to the garden – Hydrangea macrophylla ‘Wedding Gown’, Osmanthus fragrans, and Cercidiphyllum japonicum ‘Morioka Weeping’. The Plant Committee is grateful to our gardeners for continuing to provide us with critical information about changes to the plant collection. The Plant Committee (Hiroko Aikawa, Maggie Carr, Sue Clark, Kathy Lantz, chair, Corinne Kennedy, Aleksandra Monk and Shizue Prochaska) revised and updated the Plant Booklet. This year we welcome four new members to the committee – Eleanore Baxendale, Joanie Clarke, Patti Brawer and Pamela Miller. Aleksandra Monk continues to be the chief photographer of the plants in the garden and posts information about plants in bloom and seasons of interest to the SJG Community Blog and related SJG Bloom Blog. Corinne Kennedy is a frequent contributor to the SJG website and published 2 articles in the summer Washington Park Arboretum Bulletin highlighting the Japanese Garden – Designed in the Stroll-Garden Style and Hidden Treasure of the Japanese Garden. -
