Chlorogenic acid facilitates root hair formation in lettuce seedlings.
Root hairs, which arise from root epidermal cells, are tubular structures that increase the efficiency of water absorption and nutrient uptake. A low pH (pH 4) medium induced root hair formation in lettuce (Lactuca sativa L.) seedlings, and the decapitation of shoots inhibited root hair formation. The addition of shoot extract to the medium restored root hair formation in the decapitated lettuc...
متن کاملRoot exudation and root development of lettuce (Lactuca sativa L. cv. Tizian) as affected by different soils
Development and activity of plant roots exhibit high adaptive variability. Although it is well-documented, that physicochemical soil properties can strongly influence root morphology and root exudation, particularly under field conditions, a comparative assessment is complicated by the impact of additional factors, such as climate and cropping history. To overcome these limitations, in this stu...
متن کاملIntegrated Effects of Root-Zone Temperatures and Phosphorus Levels on Aeroponically-Grown Lettuce (Lactuca sativa L.) in the Tropics
In this study, butterhead lettuce (Lactuca sativa L. cv. Baby Butter) plants were grown at three root-zone temperatures (RZTs): 25 o C, 30 o C and ambient-RZT (A-RZT) ranging from 26 o C-42 o C while their shoots were maintained at hot ambient temperature ranging from 26 o C-42 o C. Three phosphorus (P) concentrations: -25% P (minus P, 23.25ppm), control (31.00ppm) and +25% P (plus P, 38.75ppm)...
متن کاملAvailability on Total Productivity, Root Morphology, Photosynthesis and Nitrogen Metabolism of Lettuce (Lactuca sativa L.) Recombinant Inbred Lines
We have identified certain heat-resistant (HR) and heat-sensitive (HS) lettuce (Lactuca sativa) recombinant inbred lines (RILs) from 113 lines under hot ambient temperature by studying the root morphology, shoot and root productivity. Except for temperature, one of the other major determinants of root morphology is nitrate (NO3 ) availability. In this study, total productivity, root morphology,...
متن کاملAsymmetric growth of root epidermal cells is related to the differentiation of root hair cells in Hordeum vulgare (L.)
The root epidermis of most vascular plants harbours two cell types, namely trichoblasts (capable of producing a root hair) and atrichoblasts. Here, in vivo analysis, confocal laser-scanning microscopy, transmission electron microscopy, histological analysis, and three-dimensional reconstruction were used to characterize the cell types present in the barley root epidermis and their distribution ...
