California's Native Ferns
CALIFORNIA’S NATIVE FERNS A survey of our most common ferns and fern relatives Native ferns come in many sizes and live in many habitats • Besides living in shady woodlands and forests, ferns occur in ponds, by streams, in vernal pools, in rock outcrops, and even in desert mountains • Ferns are identified by producing fiddleheads, the new coiled up fronds, in spring, and • Spring from underground stems called rhizomes, and • Produce spores on the backside of fronds in spore sacs, arranged in clusters called sori (singular sorus) Although ferns belong to families just like other plants, the families are often difficult to identify • Families include the brake-fern family (Pteridaceae), the polypody family (Polypodiaceae), the wood fern family (Dryopteridaceae), the blechnum fern family (Blechnaceae), and several others • We’ll study ferns according to their habitat, starting with species that live in shaded places, then moving on to rock ferns, and finally water ferns Ferns from moist shade such as redwood forests are sometimes evergreen, but also often winter dormant. Here you see the evergreen sword fern Polystichum munitum Note that sword fern has once-divided fronds. Other features include swordlike pinnae and round sori Sword fern forms a handsome coarse ground cover under redwoods and other coastal conifers A sword fern relative, Dudley’s shield fern (Polystichum dudleyi) differs by having twice-divided pinnae. Details of the sori are similar to sword fern Deer fern, Blechnum spicant, is a smaller fern than sword fern, living in constantly moist habitats Deer fern is identified by having separate and different looking sterile fronds and fertile fronds as seen in the previous image. -

Transcriptomic Characterization of Soybean - Sclerotinia Sclerotiorum Interaction at Early Infection Stages
TRANSCRIPTOMIC CHARACTERIZATION OF SOYBEAN - SCLEROTINIA SCLEROTIORUM INTERACTION AT EARLY INFECTION STAGES BY WEI WEI THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2017 Urbana, Illinois Master’s Committee: Assistant Professor Steven J. Clough, Co-Chair Associate Professor Youfu Zhao, Co-Chair Professor Glen L. Hartman ABSTRACT Sclerotinia stem rot, also referred to as white mold, poses a threat to soybean production world-wide. The causal agent, Sclerotinia sclerotiorum (Lib.) de Bary, can survive in harsh environments and has an extremely broad host range. No naturally complete resistance has been reported to exist in soybean, which makes it a compelling problem. Studying the molecular interactions between soybean and S. sclerotiorum is a promising approach to identify the soybeans genes that are controlling the quantitative resistance and, on the other hand, to discover pathogenicity and virulence factors in S. sclerotiorum which could be considered as targets to disable and weaken the aggressiveness of the pathogen. This study utilized RNA-sequencing to characterize the transcriptomes of the leaves of a susceptible soybean line (AC) and an AC transgenic line (OxO) which contains an enzyme that degrades the oxalic acid (OA) produced by S. sclerotiorum thereby conferring resistance. The leaves were infected with S. sclerotiorum and samples were collected at 4 and 8 hours post inoculation (hpi) to characterize this interaction and to examine the key determinants of resistance and infection at these early infection stages. More than 600 soybean genes were detected with a fairly stringent cutoff as being significantly differentially expressed in response to S. -

More than 250 species of the fungus have been reported in different host plants all over the world that cause heavy economic losses. It was a challenge to discover weak links in the disease cycle to manage Sclerotinia diseases of large number of crops. For researchers and stu- dents, it has been a matter of concern, how to access voluminous literature on Sclerotinia scattered in different journals, reviews, proceedings of symposia, workshops, books, abstracts etc. to get a comprehensive picture. With the publi- cation of book on ‘Sclerotinia’, it has now become quite clear that now only three species of Sclerotinia viz., S. -

Epidemiology of Sclerotinia Sclerotiorum, Causal Agent of Sclerotinia Stem Rot, on SE US Brassica Carinata
Epidemiology of Sclerotinia sclerotiorum, causal agent of Sclerotinia Stem Rot, on SE US Brassica carinata by Christopher James Gorman A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Masters of Science Auburn, Alabama May 2, 2020 Keywords: Sclerotinia sclerotiorum, epidemiology, sclerotia conditioning, apothecia germination, ascospore infection, fungicide assay Copyright 2020 by Christopher James Gorman Approved by Kira Bowen, Professor of Plant Pathology Jeffrey Coleman, Assistant Professor of Plant Pathology Ian Smalls, Assistant Professor of Plant Pathology, UF Austin Hagan, Professor of Plant Pathology ABSTRACT Brassica carinata is a non-food oil seed crop currently being introduced to the Southeast US as a winter crop. Sclerotinia sclerotiorum, causal agent of Sclerotinia Stem Rot (SSR) in oilseed brassicas, is the disease of most concern to SE US winter carinata, having the potential to reduce yield and ultimately farm-gate income. A disease management plan is currently in development which will include the use of a disease forecasting system. Implementation of a disease forecasting system necessitates determining the optimal environmental conditions for various life-stages of SE US isolates of this pathogen for use in validating or modifying such a system. This is because temperature requirements and optimums for disease onset and subsequent development may vary depending on the geographical origin of S. sclerotiorum isolates. We investigated the optimal conditions necessary for three life-stages; conditioning of sclerotia, germination of apothecia, and ascospore infection of dehiscent carinata petals. Multiple isolates of S. sclerotiorum were tested, collected from winter carinata or canola grown in the SE US. -
Desmodium Cuspidatum (Muhl.) Loudon Large-Bracted Tick-Trefoil
New England Plant Conservation Program Desmodium cuspidatum (Muhl.) Loudon Large-bracted Tick-trefoil Conservation and Research Plan for New England Prepared by: Lynn C. Harper Habitat Protection Specialist Massachusetts Natural Heritage and Endangered Species Program Westborough, Massachusetts For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, 2002 SUMMARY Desmodium cuspidatum (Muhl.) Loudon (Fabaceae) is a tall, herbaceous, perennial legume that is regionally rare in New England. Found most often in dry, open, rocky woods over circumneutral to calcareous bedrock, it has been documented from 28 historic and eight current sites in the three states (Vermont, New Hampshire, and Massachusetts) where it is tracked by the Natural Heritage programs. The taxon has not been documented from Maine. In Connecticut and Rhode Island, the species is reported but not tracked by the Heritage programs. Two current sites in Connecticut are known from herbarium specimens. No current sites are known from Rhode Island. Although secure throughout most of its range in eastern and midwestern North America, D. cuspidatum is Endangered in Vermont, considered Historic in New Hampshire, and watch-listed in Massachusetts. It is ranked G5 globally. Very little is understood about the basic biology of this species. From work on congeners, it can be inferred that there are likely to be no problems with pollination, seed set, or germination. As for most legumes, rhizobial bacteria form nitrogen-fixing nodules on the roots of D. cuspidatum. It is unclear whether there have been any changes in the numbers or distribution of rhizobia capable of forming effective mutualisms with D. -

COVER CROPS and SOIL-BORNE FUNGI DANGEROUS TOWARDS the CULTIVATION of SALSIFY (Tragopogon Porrifolius Var
Acta Sci. Pol., Hortorum Cultus 10(2) 2011, 167-181 COVER CROPS AND SOIL-BORNE FUNGI DANGEROUS TOWARDS THE CULTIVATION OF SALSIFY (Tragopogon porrifolius var. sativus (Gaterau) Br.) Elbieta Patkowska, Mirosaw Konopiski University of Life Sciences in Lublin Abstract. Salsify has a remarkable taste and nutritious values. It is a rich source of inulin – a glycoside which has a positive effect on human and animal organisms. The paper pre- sents studies on the species composition of soil-borne fungi infecting the roots of Tragopogon porrifolius var. sativus cultivated with the use of oats, tansy phacelia and spring vetch as cover crops. In a field experiment the cover crops formed abundant green mass before winter and it constituted a natural mulch on the surface of the plough land. It was managed in two ways: 1) mixed with the soil as a result of spring ploughing, or 2) mixed with the soil as a result of pre-winter ploughing. The conventional cultivation of salsify, i.e. without cover crops, constituted the control. The studies established the number and health status of four-week-old salsify seedlings and roots with necrotic signs. A laboratory mycological analysis made it possible to determine the quantitative and qualitative composition of fungi infecting the underground parts of Tragopogon porri- folius var. sativus. The emergences and the proportion of infected salsify seedlings varied and depended on the species of the mulching plant. The smallest number of infected seed- lings was obtained after the mulch with oats, slightly more after the application of spring vetch or tansy phacelia as cover crops, and the most in the control.
