Agrobacterium-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 کاملEffects of Nitrogen Fertilizers on the Growth and Nitrate Content of Lettuce (Lactuca sativa L.)
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer i...
متن کاملInflorescence Development and the Role of LsFT in Regulating Bolting in Lettuce (Lactuca sativa L.)
Lettuce (Lactuca sativa L.) is one of the most important leafy vegetable that is consumed during its vegetative growth. The transition from vegetative to reproductive growth is induced by high temperature, which has significant economic effect on lettuce production. However, the progression of floral transition and the molecular regulation of bolting are largely unknown. Here we morphologically...
متن کاملThe nitrogen and nitrate economy of butterhead lettuce (Lactuca sativa var capitata L).
Quantifying and simulating the relationships between crop growth, total-nitrogen (total-N) and nitrate-N (NO3--N) concentration can improve crop nutritional husbandry. In this study, the relationship between shoot relative growth rate (RGR) and shoot total-N, organic-N and NO3--N concentration of hydroponically-grown lettuce (Lactuca sativa var. capitata L. cv. Kennedy) was described and simula...
متن کاملInduction of Light Sensitive Dormancy in Seed of Lactuca sativa L. (Lettuce) by Patulin.
The antibiotic patiilin (I) has been reported to inhibit seed germination becauise of its toxicity (7). We considered that this butenolide (I) might induce light sensitive dormancy in seeds of lettuce because of its structural similarity to coumarin (II) and ramulosin (III), (see fig 1), which have been demonstrated to possess this biological activity (2,5,6). Possible activitv was tested in th...
