Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

Creator:: Pino, María-Teresa
Abstract:: Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

Creator:: Park, Eung-Jun
Abstract:: Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

Developing Tools for Hardy Hibiscus and Lilac Breeding: Quantile Regression, Cytogenetics, Interspecific Hybridization, Somatic Hybridization, and Marker-Trait Association

Creator:: Chen, Hsuan
Abstract:: Hibiscus and lilacs (Syringa spp.) are economically important nursery crops in the US that accounted for 4.5 million units ($30 million) and 2 million units ($20 million), respectively (USDA, 2016). To maintain and expand the market share of ornamental plants such as lilacs and Hibiscus, novel performance, floral ornamental value,...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...

Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:: Eskelsen, Steven R.
Abstract:: Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...

Changes in developing strawberry fruit : I. Cell division and enlargement ; and II. Biosynthesis of anthocyanins and other phenolics and activity of associated enzymes

Creator:: Cheng, Guiwen
Abstract:: Size and color are important visual quantity attributes of the fruit of strawberry (Fmgaria x ananassa Duch.). Strawberry cultivars produce fruit of a characteristic size and color, the later being the result of accumulation of particular anthocyanins. This research sought to determine the basis for genotypic differences in fruit size...

Relationship of "near-lethal" stress on dormancy, cold hardiness and recovery of Red-Osier dogwood

Creator:: Shirazi, Abbas M.
Abstract:: The effects of overcoming rest by application of "near-lethal" (NL) stress treatments on the subsequent development of cold hardiness of stem tissues of red-osier dogwood, Comus sericea L., at different rest stages under three post-environments (0°, 23°, and natural condition) were studied. NL-heat stress (47°C for one hour) treatment during...

Exploration of the feasibility of developing a winter hardy 'Marion' blackberry through genetic engineering

Creator:: Meng, Rengong
Abstract:: Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...
