Mary Birkett Card (1774-1817): Struggling to Become the Ideal Quaker Woman

This paper is based on The Works of Mary Birkett Card 1774 -1817, an edition of the manuscript collection made by her son Nathaniel Card in 1834. The collection contains different genres and spans Card\u27s life from childhood to near her death, forming a unique record of one woman\u27s experience at the tum of the eighteenth and nineteenth centuries. Themes of self and identity, women\u27s participation in public and private spheres, and ideological differences are apparent in Mary Birkett Card\u27s struggle, in life and text, to become \u27the ideal Quaker woman\u27. One particular focus is on her negotiation of Quaker ideology in relation to her literary creativity. It is argued that dramatic changes in her writing resulted from efforts to contain her literary imagination in line with \u27plainer\u27 Quaker aesthetic values and more restrictive ideas about the most appropriate forms of creativity for her as a woman and a Friend

Lotus tenuis tolerates combined salinity and waterlogging: maintaining O2 transport to roots and expression of an NHX1-like gene contribute to regulation of Na+ transport

Salinity and waterlogging interact to reduce growth for most crop and pasture species. The combination of these stresses often cause a large increase in the rate of Na+ and Cl− transport to shoots; however, the mechanisms responsible for this are largely unknown. To identify mechanisms contributing to the adverse interaction between salinity and waterlogging, we compared two Lotus species with contrasting tolerances when grown under saline (200 mM NaCl) and O2-deficient (stagnant) treatments. Measurements of radial O2 loss (ROL) under stagnant conditions indicated that more O2 reaches root tips of Lotus tenuis, compared with Lotus corniculatus. Better internal aeration would contribute to maintaining Na+ and Cl− transport processes in roots of L. tenuis exposed to stagnant-plus-NaCl treatments. L. tenuis root Na+ concentrations after stagnant-plus-NaCl treatment (200 mM) were 17% higher than L. corniculatus, with 55% of the total plant Na+ being accumulated in roots, compared with only 39% for L. corniculatus. L. tenuis accumulated more Na+ in roots, presumably in vacuoles, thereby reducing transport to the shoot (25% lower than L. corniculatus). A candidate gene for vacuole Na+ accumulation, an NHX1-like gene, was cloned from L. tenuis and identity established via sequencing and yeast complementation. Transcript levels of NHX1 in L. tenuis roots under stagnant-plus-NaCl treatment were the same as for aerated NaCl, whereas L. corniculatus roots had reduced transcript levels. Enhanced O2 transport to roots enables regulation of Na+ transport processes in L. tenuis roots, contributing to tolerance to combined salinity and waterlogging stresses

The works of Mary Birkett Card 1774-1817 originally collected by her son Nathaniel Card in 1834: an edited transcription with an introduction to her life and works in two volumes

This thesis makes available the writings of Mary Birkett Card, a Dublin Quaker, as collected by her son Nathaniel Card in 1834. It provides an annotated transcription of the manuscript collection, with textual and editorial notes, and an introduction recovering her life within her cultural community. The writings consist of a spiritual autobiography, 43 religious letters, other prose pieces and over 220 poems. Two poems were published in her lifetime: A Poem on the African Slave Trade (1792) and Lines to the Memory of our Late Esteemed and Justly Valued Friend Joseph Williams (1807). The introduction is in three parts. Part 1 offers a biographical outline and sets Mary Birkett Card's childhood poems in the context of the Quaker community in which she grew up. Part 2 explores her autobiography, questioning concepts of a separate female autobiographical tradition. It then investigates her encounter with 'deist' thought, and later conflicts, after her marriage. These concern money (seeking to reconcile the spiritual and material) and issues of language and gender (a desire for'a pure language', linked to constraints upon women's speech). Part 3 contrasts her 1790s verse with her later poems, and epistles, arguing that embedded within these works as a whole lies a struggle with her literary imagination. Throughout, the writings are set within the context of contemporary literary forms in poetry, Quaker writing and women's writing. They are considered in relation to now current critical debates - on public and private spheres, autobiography, abolitionist verse, women's intimate friendships, domesticity, philanthropy and sensibility. It is shown that Mary Birkett Card's literary creativity was intimately connected with her Quakerism, and, moreover, with attempts to negotiate an ideal of Quaker womanhood. One important aspect is the challenge her work poses to assumptions, still generally prevalent, about Quaker women's far greater autonomy within marriage in comparison to women in society at large

Breeding for improved nitrogen use efficiency in oilseed rape

Oilseed rape has a high requirement for nitrogen (N) fertiliser relative to its seed yield. This paper uses published and unpublished work to explore the extent to which the N use efficiency (seed yield ÷ N supply) of oilseed rape could be improved without reducing seed yield. It was estimated that if the concentration of N in the stem and pod wall at crop maturity could be reduced from 1.0 to 0.6%, the root length density increased to 1 cm/cm3 to 100 cm soil depth and the post flowering N uptake increased by 20 kg N/ha then the fertiliser requirement could be reduced from 191 to 142 kg N/ha and the N use efficiency could be increased from 15.2 to 22.4 kg of seed dry matter per kg N. Genetic variation was found for all of the traits that were estimated to be important for N use efficiency. This indicates that there is significant scope for plant breeders to reduce N use efficiency in oilseed rape

WATERMELON MOSAIC VIRUS OF PUMPKIN (Cucurbita maxima) FROM SULAWESI: IDENTIFICATION, TRANSMISSION, AND HOST RANGE

A mosaic disease of pumpkin (Cucurbita maxima) was spread widely in Sulawesi. Since the virus had not yet been identified, a study was conducted to identify the disease through mechanical inoculation, aphid vector transmission, host range, and electron microscopic test. Crude sap of infected pumpkin leaf samples was rubbed on the cotyledons of healthy pumpkin seedlings for mechanical inoculation. For insect transmission, five infective aphids were infected per seedling. Seedlings of eleven different species were inoculated mechanically for host range test. Clarified sap was examined under the electron microscope. Seeds of two pumpkin fruits from two different infected plants were planted and observed for disease transmission up to one-month old seedlings. The mosaic disease was transmitted mechanically from crude sap of different leaf samples to healthy pumpkin seedlings showing mosaic symptoms. The virus also infected eight cucurbits, i.e., cucumber (Cucumis sativus), green melon (Cucumis melo), orange/rock melon (C. melo), zucchini (Cucurbita pepo), pumpkin (Cucurbita maxima), water melon (Citrulus vulgaris), Bennicosa hispida, and blewah (Cucurbita sp.). Aphids  transmitted the disease from one to other pumpkin seedlings. The virus was not transmitted by seed. The mosaic disease of pumpkin at Maros, South Sulawesi, was associated with flexious particles of approximately 750 nm length, possibly a potyvirus, such as water melon mosaic virus rather than papaya ringspot virus or zucchini yellow mosaic virus
