G16 Family: Poaceae. Description: Deep rooted tussock-forming perennial to 1.3 m tall. Leaves to 50 cm long, 4–8 mm wide, hairless or with scattered hairs, with a scabrous point and margins. Key features: Seedhead an unbranched spike to 30 cm long that breaks up at maturity, the spikelets placed with the flat side to the axis. Value: The most common cultivar is Tyrrell; DPI Victoria in 2001 released a more leafy cultivar named Dundas. Slow to establish and should not be grazed in its first year. Responds to hard grazing and the application of nitrogen. Subsoil moisture or summer rainfall is necessary for good production. Highly productive and of high nutritive value (supports high animal growth rates) if kept vegetative and leafy, but will revert to low nutritive value and palatability (less than a maintenance feed) if allowed to grow rank and set seed. Can be highly invasive in wetland areas. Salinity and waterlogging tolerance: Does not persist in soils that are waterlogged over spring and into summer. Grows in soils that have low to moderate salinity. Notes: Native of southern and eastern Europe, western Asia. Used in rehabilitation projects where there are soils with H moderate salinity (up to EC 30 dS/m). M References: Saltland Pastures in Australia, Barrett-Lennard, 2003.

Effects of Agronomic Treatments on Silphium integrifolium, a Potential Perennial Oilseed A Thesis SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Sydney A. Schiffner IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE Craig C. Sheaffer, Advisor August 2018 © Sydney Schiffner 2018 Acknowledgements I would first like to thank my advisor, Dr. Craig Sheaffer, for allowing me to pursue a degree in Applied Plant Sciences on the Agronomy/Agroecology track within his lab. I would next like to thank Dr. Jacob Jungers, and Dr. Nicole Tautges for their assistance with interpreting findings and help with statistical analysis on my data. Next I would like to thank lab technicians Joshua Larson, Lindsay Wilson and Donn Vellekson for their assistance in field management and data collection. Thanks also to the Sustainable Cropping System/Forages lab and all of the interns and MAST students that helped make my research possible with their dedication to good science and field research. This project was funded by the Malone Foundation through The Land Institute, and I would like to thank Dr. David Van Tassel at The Land Institute for being on call whenever I had any odd question about silphium. Thank you to my friends and family who have supported me through this rigorous scientific endeavor, and last of all thank you to my fellow graduate students. Without your fellowship for the past few years, I definitely wouldn’t have made it through graduate school, or had as much of a fun time going through it.

Transgenic Wheat Expressing Thinopyrum Intermedium MYB Transcription Factor Timyb2r-1 Shows Enhanced Resistance to the Take-All Disease

Breeding resistant cultivars is an effective way to protect wheat from take-all. However, little progress has been made in improving the disease resistance level in commercial wheat cultivars. MYB transcrip- tion factors play important roles in plant responses to environmental stresses. In this study, an R2R3-MYB gene in Thinopyrum intermedium, TiMYB2R-1, was cloned and characterized. The gene sequence includes two exons and an intron.

Plant Guide for Intermediate Wheatgrass (Thinopyrum Vigorous Seedlings, Rapidly Developing Rhizomes, Intermedium)
Plant Guide INTERMEDIATE It produces good hay yields, both in monoculture and in mixtures with alfalfa (Medicago spp.), where its WHEATGRASS stiff stems tend to keep alfalfa from lodging. Thinopyrum intermedium Intermediate wheatgrass has fairly slow re-growth (Host) Barkworth & D.R. following clipping and is best adapted to single crop- haying conditions (where rainfall patterns or limited Dewey irrigation prevents multiple cuttings in a season). Plant Symbol = THIN6 Intermediate wheatgrass responds very well to irrigation with initial production nearing the level of Contributed by: USDA NRCS Idaho Plant Materials orchardgrass (Dactylis glomerata) and meadow Program brome (Bromus biebersteinii) and exceeding smooth brome (Bromus inermis) under full irrigation. Meadow brome and orchardgrass have much better regrowth characteristics and will normally produce more than intermediate wheatgrass for hay production in multiple cutting situations. Intermediate wheatgrass responds very well to limited irrigation. It is able to tolerate droughty conditions when irrigation ceases as long as about 12-14 inches or more total annual moisture is provided. It provides excellent spring, early summer, and fall pasture, but must be carefully managed to ensure maintenance of the stand and high production. Intermediate wheatgrass is palatable to all classes of livestock and wildlife. It is a preferred feed for cattle, sheep, horses, deer, antelope, and elk in spring, early summer and fall. It is considered a desirable feed for cattle, sheep, horses, and elk in summer and winter. Erosion control/reclamation: Intermediate wheatgrass is well adapted to the stabilization of disturbed soils. This grass can be used in critical and urban areas where irrigation water is limited and to stabilize ditch banks, dikes, and roadsides.

Resistance to soil-borne diseases of wheat: Contributions from the wheatgrasses Thinopyrum intermedium and Th. ponticum. Can. J. Plant Sci. 88: 195Á205. Eyespot, Cephalosporium stripe, and common root rot are soil-borne diseases that damage the stem bases, vascular system, subcrown internodes, and roots of wheat. Resistance in wheat to these diseases is insufficient to prevent significant yield loss when disease is severe. The wheatgrasses Thinopyrum intermedium and Th. ponticum are highly resistant to these diseases. Identification of disease- resistant wheat-Thinopyrum partial amphiploids, chromosome addition, substitution, and translocation lines makes them a valuable source of resistance genes for wheat breeding programs. Single chromosomes or chromosome segments containing resistance genes can be transferred into wheat to produce genetic stocks that afford a better understanding of the genetic control of resistance in wheatgrasses and new genetic resources for wheat improvement. Resistance to eyespot in Th. intermedium and Th. ponticum was associated with the homoeologous group 4 chromosomes, whereas resistance to Cephalosporium stripe was controlled by genes located on chromosomes 3 and 6 of Th.

Brentwood Blvd. St. Louis, Missouri 63144 [email protected] JUSTIN R. THOMAS Institute of Botanical Training, LLC 111 County Road 3260 Salem, Missouri 65560 [email protected] ABSTRACT An annotated checklist of the 2,961 vascular taxa comprising the flora of Missouri is presented, with conservatism rankings for Floristic Quality Assessment. The list also provides standardized acronyms for each taxon and information on nativity, physiognomy, and wetness ratings. Annotated comments for selected taxa provide taxonomic, floristic, and ecological information, particularly for taxa not recognized in recent treatments of the Missouri flora. Synonymy crosswalks are provided for three references commonly used in Missouri. A discussion of the concept and application of Floristic Quality Assessment is presented. To accurately reflect ecological and taxonomic relationships, new combinations are validated for two distinct taxa, Dichanthelium ashei and D. werneri , and problems in application of infraspecific taxon names within Quercus shumardii are clarified.

Abstract Background: Plant resistance (R) gene products recognize pathogen effector molecules. Many R genes code for proteins containing nucleotide binding site (NBS) and C-terminal leucine-rich repeat (LRR) domains. NBS-LRR proteins can be divided into two groups, TIR-NBS-LRR and non-TIR- NBS-LRR, based on the structure of the N-terminal domain. Although both classes are clearly present in gymnosperms and eudicots, only non-TIR sequences have been found consistently in monocots. Since most studies in monocots have been limited to agriculturally important grasses, it is difficult to draw conclusions.
