Botany Of Desire: Looking At The Rose Plant As A Manmade Tool Of Love, Taylor Aaserud

Undergraduate Review: a Journal of Undergraduate Student Research

The use of roses as a symbol of emotion (specifically love) and as a result, a model of artificial selection, is rarely questioned. These plants share a rich history with multiple humanities around the world and have been a subject of genetic interest to see exactly what genes are being expressed that signal those beautiful desirable traits. To answer the question of “why” these plants have been a vector for human love for so long, I have analyzed 7 articles, one of them outlining the cause of the favored “double flower” mutation found in so many modern roses today. Upon ...

Review Of The Purple Amole Chlorogalum Purpureum (Agavaceae): A Threatened Plant In The Coast Ranges Of Central California, Christopher P. Kofron, Connie Rutherford, Elizabeth R. Clark, Darlene Woodbury, Jody Olson, Robert F. Holland

Bulletin of the Southern California Academy of Sciences

The purple amole Chlorogalum purpureum (Agavaceae) is a bulbous, perennial soap plant endemic to central California and listed as threatened under the U.S. Endangered Species Act since 2000. Chlorogalum p. purpureum occurs in the rain shadow of the Santa Lucia Range on Fort Hunter Liggett, south Monterey Co., and on Camp Roberts, north San Luis Obispo Co. Chlorogalum p. reductum occurs in the rain shadow of the La Panza Range in central San Luis Obispo Co., mostly on Los Padres National Forest and with potential for a substantially larger occupied area on private land. We review and enhance the ...

La Serreta Endokarst (Se Spain): A Sustainable Value?, Antonia D. Asencio, Teodoro Espinosa

International Journal of Speleology

La Serreta endokarst (SE Spain), which UNESCO declared a World Heritage Site in 1998, was considered a sanctuary with cave art and one of the most important archaeological sites in the Mediterranean region for both the remains it hosts and the spectacular karstic landscape at the site.

To coincide with the 40th anniversary of its discovery, the La Serreta cave-chasm was adapted for public use with the intention of showing visitors the remains, which date back to prehistoric times. The solution included attempts to minimize contact with the valuables in the cave in order to alter the existing remains as ...

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano

Landscapes: the Journal of the International Centre for Landscape and Language

Abstract. In this article, I examine human-plant perceptions and interactions in terms of developing a new perspective on the perception and the actions of people towards plants. By combining my scientific understanding of the biological world and my own experiences working with plant shamans, storytellers and mystics from around the world, I engage with the idea that the hierarchical structure by which Western science defines the variety of life forms as ‘primitive’ or ‘more evolved’ is at the root of the current environmental crisis and I argue that the solution to it rests in a change of this very perspective.

A Comparative Analysis Of The Relative Water Content Of The Pollen Of Early Diverging Angiosperms, Andrew Robert Moffatt

Ecology and Evolutionary Biology Publications and Other Works

The pollen of most angiosperms goes through a process of dehydration before anthesis, the opening of the flower (Heslop-Harrison 1979a). During dispersal, further dehydration often occurs (Heslop-Harrison 1979b). Dehydrated pollen comes in two degrees: hydrated (also termed desiccation-sensitive or recalcitrant) at greater than 30% water content by mass and dehydrated (also termed desiccation-tolerant or orthodox) at less than 30% water by mass (Franchi et al 2002, 2011). Most species tend to undergo some degree of dehydration, or developmental arrest, before anther opening (Franchi et al 2002). Angiosperms are known to have much faster reproductive processes than other seed plants, which ...

High School Horticulture Curriculum, Margaret Maratsos

Horticulture and Crop Science

Horticulture is just one of the many topics covered in a high school agriculture curriculum, and yet, there are very few lesson plans or resources available to teachers for these classes specifically. The objectives of this project were to compile a set of lesson plans, lab plans, and tests that would emphasize interactive and investigative learning. The lesson plans were written in such a way that they reflected a certain set of standards, set down by the state of California, and were meant to serve as a bare outline of topics that would be discussed within a week’s worth ...

The Role Of Olfactory Cues In The Sequential Radiation Of A Gall-Boring Beetle, Mordellistena Convicta, Bradley C. Rhodes, Catherine P. Blair, Mizuki K. Takahashi, Warren G. Abrahamson Ii

Warren G. Abrahamson, II

1. Herbivorous insects often have close associations with specific host plants, and their preferences for mating and ovipositing on a specific host-plant species can reproductively isolate populations, facilitating ecological speciation. Volatile emissions from host plants can play a major role in assisting herbivores to locate their natal host plants and thus facilitate assortative mating and host-specific oviposition. 2. The present study investigated the role of host-plant volatiles in host fidelity and oviposition preference of the gall-boring, inquiline beetle, Mordellistena convicta, using Y-tube olfactometers. Previous studies suggest that the gall-boring beetle is undergoing sequential host-associated divergence by utilizing the resources that ...

Morphological And Anatomical Characteristics Of Blackbrush (Coleogyne Ramosissima Torr.) Leaves: A Review Of Literature, Simon Lei

Bulletin of the Southern California Academy of Sciences

Leaves of blackbrush (Coleogyne ramosissima Torr.) shrubs share a number characteristics of leaves of both xerophytic and sclerophyllous shrubs. Despite some leaf surface (morphological) and anatomical similarities with typical xerophytic leaves, blackbrush leaves are more similar to typical semi-arid coastal chaparral plants in Mediterranean and southern California, or cool and high elevation inland desert perennial plants. Semi-deciduous, thick blades, well-cutinized epidermises, numerous small leaves, sclerophyllic leaves, hypostomatry, sunken stomata, thickened epidermal cell walls, and abundant abaxial and adaxial trichomes are characteristics of blackbrush plants, as well as typical woody xerophytic and sclerophyllous plants. Blackbrush also exhibit summer dormancy, with characteristics ...

Effects Of Burial Depth And Substrate On The Emergence Of Bromus Rubens And Brassica Tournefortii, Abella R. Scott, Amber C. Lee, Alexis A. Suazo

Bulletin of the Southern California Academy of Sciences

The germination of seed is critical in deserts where annual plants are abundant and rely on seed buried in the soil for sustaining populations. The exotic annuals Bromus rubens and Brassica tournefortii threaten arid indigenous ecosystems such as the Mojave Desert, but little is known about the potential effects on seed emergence of different burial depths and substrates that could enhance or reduce emergence. Using seed from Mojave Desert populations, we conducted a threefactor greenhouse experiment testing the effects of species (Bromus or Brassica), burial depth (0, 2, 5, or 10 cm), and substrate (none, gravel, or litter) on seed ...

East Asian Plants In Eastern Us Forests: Are Invaders Pre-Adapted For More Efficient Resource Use? (Talk), Mason Heberling, Jason Fridley

Mason Heberling

The globalization of human activities has resulted in the widespread movement of plants around the world. Paradoxically, many of these exotic species are out-competing native plants, despite the presumption that native species have locally adapted to their environments. Further, global invasion patterns are frequently asymmetric, with some regions more likely to produce invasive species and others more likely to be invaded. This phenomenon is particularly prominent in eastern North American (ENA) forests, where an unexpected, substantial fraction of woody invaders originated from East Asia (EAS). Although both regions lie primarily in the north temperate mesic forest biome with comparable niches ...

The Spatial Signature Of Biotic Interactions Of A Clonal And A Non-Clonal Palmetto In A Subtropical Plant Community, Mizuki K. Takahashi, Toshiro Kubota, Liana M. Horner, Nathan A. Keller, Warren G. Abrahamson Ii

Warren G. Abrahamson, II

Spatial analyses of plant-distribution patterns can provide inferences about intra- and interspecific biotic interactions. Yet, such analyses are rare for clonal plants because effective tools (i.e., molecular markers) needed to map naturally occurring clonal individuals have only become available recently. Clonal plants are unique in that a single genotype has a potential to spatially place new individuals (i.e., ramets) in response to intra- and interspecific biotic interactions. Laboratory and greenhouse studies suggest that some clonal plants can avoid intra-genet, inter-genet, and inter-specific competition via rootplacement patterns. An intriguing and yet to be explored question is whether a spatial ...

Involvement Of Hexokinase1 In Plant Growth Promotion As Mediated By Burkholderia Phytofimans, Jae Min Park

University of Western Ontario - Electronic Thesis and Dissertation Repository

Burkholderia phytofirmans strain PsJN consistently enhanced the growth of potato plants in vitro. The role of hexokinase1 in glucose phosphorylation was investigated in plants with PsJN. Increased hexokinase1 activity only in roots of PsJN-treated plants cultivar Kennebec suggests that hexokinase1 is associated with plant root and stem growth.

Plant growth with PsJN was determined when plants were grown with different sugars at various concentrations. PsJN-treated plants expressed diverse forms of growth promotion. When growth promotion did occur, hexokinase1 activity also increased. Growth promotion and hexokinase1 activity appear to be correlated to the enzyme to recognize the substrate for catalytic activity ...

Hairy Roots As A Model To Investigate The Role Of Suberin In The Phytophthora Sojae-Soybean Pathosystem, Pooja Sharma

University of Western Ontario - Electronic Thesis and Dissertation Repository

Part of the resistance mechanism of soybean (Glycine max [L.] Merr.) to Phytopthora sojae Kauf. & Gerd. involves pre-formed root suberin. In order to investigate the role of suberin in this host-pathogen interaction, I characterized hairy roots, formed as a result of Agrobacterium rhizogenes (Riker et al.) Conn infection, as a model to be used as a reliable soybean transformation system. I established hairy root cultures and demonstrated that they were a result of A. rhizogenes infection. The anatomy and suberin deposition in soybean hairy roots was examined, and found to be very similar to that of wild-type roots. In hairy ...
