Lily leaf spot, a fungal foliar disease caused by Pseudocercosporella inconspicua, leads to premature senescence of aboveground tissues in Lilium grayi. At Roan Mountain, North Carolina/Tennessee, the disease was most prevalent and most severe in seedlings and juveniles. In the two growing seasons assessed, 59 and 70% of mature plants experienced disease-induced premature senescence. Plants with disease lesions on seed capsules matured fewer capsules and had fewer seeds per capsule, and seeds had reduced viability. Disease prevalence over the growing season followed a sigmoidal pattern typical of polycyclic epidemics. Plants with low and high disease severity occurred in clusters whose locations were stable across growing seasons. Prior to the recent description of lily leaf spot, L. grayi was already considered threatened or endangered in each of the three states where it naturally occurs. Therefore, this infectious disease poses conservation and management difficulties because increases in plant density can be expected to lead to enhanced disease transmission. Lily leaf spot of L. grayi is best characterized as an annually recurring epidemic because of high prevalence rates, strong impacts on all life stages, and reductions in seed production and viability.

The ghost story--in all its forms--has haunted humans since the first tales of the strange and inexplicable were told around the campfires of pre-history. Such stories explore collective ideas of death and the afterlife, the eeriness of certain places, and the awe that is felt in the presence of the Unknown. Pictures of Lily and Other Stories contains three examples of the genre, each written in a different sub-genre. "Money," the story of an impoverished college student who gets a housesitting job that is more perilous than it first appears, owes much to the haunted house stories of British master M.R. James, while "Under the House" parallels the haunted love stories of Edith Wharton. Finally, the novella "Pictures of Lily" explores gothic themes in the tradition of Shirley Jackson and Oscar Wilde.

<p>The flower is debatably the most complex of the plant organs, composed of far more tissues than any other plant organ system, and, as such, the molecular mechanisms that govern tissue specification and development have only just begun to be explored. One tissue that has seen little research is the stigma. The stigma is the apical-most part of the gynoecium and is designed to trap pollen grains on specialized cells called stigma papillae and provide the means for them to germinate. Using a forward genetic screen, many mutants which exhibit defects in stigma development were identified. The identification of the genes with the causative mutations will uncover new genes involved in stigma development which can be linked to previously discovered genes to build a more comprehensive gene regulatory network of stigma specification. Over the course of the screen, a new mutant, <i>lily</i>, was identified which has open buds throughout most of flower development. This valuable genetic tool allows microscopy and chemical applications at younger stages than emasculation allows. Here, <i>lily</i> was used to show the importance of reactive oxygen species in stigma specification and identity maintenance. In addition to specification, the morphological differentiation of stigma papillae was investigated. Using reverse and chemical genetics, live-imaging, and morphometrics, it was found that stigma papillae grow via an anisotropic diffuse growth mechanism. Collectively, these findings constitute a substantial breaking of ground for stigma research, providing a solid foundation for future investigation.</p>

<p>This essay focuses on the character of Lily Briscoe in Virginia Woolf's <em>To the Lighthouse. </em>From a gender perspective it discusses Lily's striving to exceed her socially constructed position as a woman by attempting to be an artist. At the beginning of the twentieth century women were supposed to be housewives rather than artists. This ideology of femininity held women back from achieving anything outside the home, and forced women to attempt to escape their femininity in order to pursue their dreams. This essay discusses Lily's efforts to escape her femininity by attempting to transcend her body and by striving to achieve an androgynous mind.</p>

This thesis critiques the representations, and lacunas in representation, of teenage girls’ sexual desires in a selection of young adult (YA) novels written since the turn of the millenium, considering their contributions either to a necessary opening up of a cultural discourse of girls’ desire, or to the prevalent dangerous silencing of such a discourse. It takes as a point of departure the perspective that, to the extent that YA fiction engages with that which is sexy about sex, it is an ideal safe, private space for girls’ exploration of their sexual subjectivities. Through critical analysis informed by interdisciplinary and cross-disciplinary perspectives, as well as by autoethnographic life writing, the research uncovers a marked tendency for YA fiction to construct girls’ desire as doubly wrong: girls are most commonly represented not only as the wrong gender for desire, but also as having individual particularities that are wrong for desire. Thus South African heroines are constructed as inhabiting the wrong country for desire, their desires inextricably linked to violence. Bisexual heroines are constructed as liking the wrong objects of desire, their desires desexualized, monosexualized, and submerged under essentialist stereotype. And conspicuous-breasted girls who experienced puberty early are constructed as possessing the wrong bodies for desire, representation of them among YA heroines largely an inhospitable absence. The research supports, however, the contention that spaces for the liberation of a genuine discourse of girls’ desire may be found in lesbian-focussed stories that hold themselves apart from the patriarchy of compulsory heterosexuality; and it finds that such spaces may also be carved out by heroines who interrogate their own desires in thoughtful, nuanced ways and, especially, by the exceptional few stories that engage with that which is sexy about sex, and thus open a discourse of desire through the direct evocation of desire itself. / Thesis (DLitt (English))--University of Pretoria, 2019. / English / DLitt (English) / Unrestricted
