Phosphomannose isomerase gene for selection in lettuce (Lactuca sativa L.) transformation.
A positive selection system using phosphomannose isomerase was employed for Agrobacterium tumefaciens mediated transformation of lettuce (Lactuca sativa L. var. 'Achát'). It was shown that the mannose-based selection system works very well with the lettuce genotype used, reaching up to 25% transformation efficiency on the medium with 20 g/L mannose and 20 g/L sucrose. The best transformation ef...
متن کاملImproving Water Use Efficiency of Lettuce (Lactuca sativa L.) Using Phosphorous Fertilizers
A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...
متن کاملAgrobacterium-mediated transformation of cotyledonary leaf of lettuce (Lactuca sativa L.) by the GCHI gene
Lactuca sativa is widely used as a leafy vegetable belonging to the Asteraceae family. Cotyledonary leaves of in vitro lettuce seedlings were transformed by plasmids containing the GCHI gene. Also the effects of number of days of pre-cultivation and co-cultivation of explants were examined on the transformation frequency. After co-cultivation, the explants were transferred onto the regeneration...
متن کاملCross-contamination of lettuce (Lactuca sativa L.) with Escherichia coli O157:H7 via contaminated ground beef.
A lettuce outbreak strain of E. coli O157:H7 was used to quantitate the pathogen's survival in ground beef and its transfer to hands, cutting board surfaces, and lettuce. Overnight storage of inoculated beef at 4 degrees C resulted in no pathogen growth, while room-temperature storage allowed multiplication. Hamburger patty formation allowed the transfer of bacteria to hands. Contaminated finge...
متن کاملCarotenoids of lettuce (Lactuca sativa L.) grown on soil enriched with spent coffee grounds.
The impact of spent coffee grounds on carotenoid and chlorophyll content in lettuce (Lactuca sativa L. var. capitata) was evaluated. A greenhouse pot experiment was conducted with spent coffee amounts ranging from 0% to 20% (v/v). All evaluated pigments increased proportionally to spent coffee amounts. Lutein and β-carotene levels increased up to 90% and 72%, respectively, while chlorophylls in...
