    GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear.

  • Cordyline Petiolaris Broad Leaved Palm Lily Friends Description Cordyline Petiolaris (Syn: Cordyline Terminalis Var
    Plant in Focus, June 2018 Cordyline petiolaris Broad Leaved Palm Lily Friends Description Cordyline petiolaris (syn: Cordyline terminalis var. petiolaris) is a medium- sized palm-like, strappy, understory plant, growing to a maximum of 5 metres in height in its natural habitat. of It is an Australian native plant, endemic to the east coast rain forests of northern Geelong Botanic Gardens NSW and southern Queensland. The mid-green leaves are long - up to a metre - and around 15 cm wide. It can be multi-trunked. It has white or lilac small flowers in late winter to early spring. These are followed by spectacular panicles of red berries which can persist for many months. The berries attract attention at this time of year under the large Araucaria bidwillii that is a focus of our Twenty First Century Garden. Cordyline petiolaris is one of several Australian native Cordylines. Name and classification 'Cordyline' is from the Greek 'Kordyle', which means 'club'. Some sources say this refers to the large underground rhizomes of the genus; others say this refers to swellings on the trunks of some Cordyline petiolaris. C21 Garden, GBG. species. Above: June 2018. Photo: CC. Below and over page: Jan 2018. Photo: DJ. 'Petiolaris' means 'stalked', and refers to the long stalks on the flowers (and berry panicles). Cordylines were once commonly classified in the Lilyaceae family, while other botanists placed them in the Agavaceae family. They are now formally placed in the Asparagaceae family. Further information of interest Cordylines are of special interest to Australians because they link us to the South Pacific.

  • Diversity in Host Preference of Rotylenchus Spp. Y.S
    International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 7, No 5, 2018, 1786 – 1793 2277-663X (P) DIVERSITY IN HOST PREFERENCE OF ROTYLENCHUS SPP. Y.S. Rathore Principal Scientist (Retd.), Indian Institute of Pulses Research, Kanpur -208024 (U.P.) E-mail: [email protected] Abstract: Species of the genus Rotylenchus are ecto- or semi-endo parasites and feed on roots of their host plants. In the study it was found that 50% species of Rotylenchus were monophagous and mostly on plants in the clade Rosids followed by monocots, Asterids and gymnosperms. In general, Rosids and Asterids combined parasitized more than 50% host species followed by monocots. Though food preference was species specific but by and large woody plants were preferred from very primitive families like Magnoliaceae and Lauraceae to representatives of advanced families. Woody plants like pines and others made a substantial contribution in the host range of Rotylenchus. Maximum number of Rotylenchus species harboured plants in families Poaceae (monocots), Rosaceae (Rosids) and Oleaceae (Asterids) followed by Fabaceae, Fagaceae, Asteraceae and Pinaceae. It is, therefore, suggested that agricultural crops should be grown far away from wild vegetation and forest plantations. Keywords: Rotylenchus, Magnoliids, Rosids, Asterids, Gymnosperms, Host preference. INTRODUCTION Species of the genus Rotylenchus (Nematoda: Haplolaimidae) are migratory ectoparasites and browse on the surface of roots. The damage caused by them is usually limited to necrosis of penetrated cells (1). However, species with longer stylet penetrate to tissues more deeply and killing more cells and called as semi-endoparasites (2,3). The genus contains 97 nominal species which parasitize on a wide range of wild and cultivated plants worldwide (3).

Composition, structure and restoration potential of riparian forest remnants, Hawke’s Bay, New Zealand A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science (Research) in Ecology and Biodiversity [Faculty of Science & Engineering] at The University of Waikato by Moari Denise West 2021 Abstract Extensive modification of riparian zones across the globe has seen a reduction in the important functions and services provided by the vegetation. Maintaining water quality, sediment control, nutrient cycling, habitat provision, climate change mitigation, and increased biodiversity value are a few of the services provided by riparian vegetation. Within New Zealand, approximately 16,000 ha of native forest has been cleared in recent times. This forest loss, compounded by historical forest loss over the previous seven centuries (14 million ha as of 2002), alongside the important services, gives native forests occurring within riparian zones increased value.
